Abstract
Description
[Technical Field]
[0001] The present invention relates to a composition for preventing, alleviating, improving or treating female hormone dysregulation disorders or symptoms, which comprises a green tea extract with an altered component content. [Background technology]
[0002] Premenstrual syndrome (PMS) refers to the physical and mental symptoms experienced by women during their fertile period. PMS is known to occur during the latter half of the luteal phase, approximately one week before menstruation, when the body's progesterone levels decrease, leading to a decrease in endorphin levels. While the intensity and duration of PMS pain vary from person to person, 10-15% of women experience physical and mental pain severe enough to interfere with their daily lives. Severe menstrual pain can also cause severe abdominal pain, along with nausea, vomiting, diarrhea, headaches, and dizziness. Pain-related stress and depression can also occur, potentially interfering with social activities such as work and school. Therefore, preventing, alleviating, and treating PMS is crucial for women's normal activities and lifestyles.
[0003] The International Health Organization (WHO) also classifies premenstrual syndrome and menstrual pain as diseases requiring treatment under the disease classification code N94 (N943: premenstrual syndrome, N944: primary dysmenorrhea, N945: secondary dysmenorrhea). The number of patients receiving medical treatment for menstrual pain is increasing year by year, resulting in rising social medical costs. According to a survey conducted by the National Health Insurance in Korea, the number of patients receiving treatment for menstrual pain (N94) increased by 47.93% in 2011, and the resulting health insurance medical costs increased by 78.85% over the five-year period (2007-2011). Therefore, there is a growing need for effective and safe treatments for premenstrual syndrome and menstrual pain to reduce these social losses.
[0004] Treatments for the relief and treatment of premenstrual syndrome and menstrual cramps include symptomatic treatments such as keeping the lower abdomen warm, avoiding cold foods, light exercise, and taking warm showers to promote blood circulation. Medical treatments include the administration of prostaglandin inhibitors, estrogen therapy (which suppresses ovulation and maintains anovulation), progesterone therapy, testosterone therapy, and tocolytics. The most common treatment involves the administration of painkillers (typically aspirin-based drugs) that inhibit prostaglandin synthesis. However, their use is limited for those with aspirin-based drug allergies or digestive disorders. While these drugs are effective in temporarily reducing pain, they do not provide relief from the emotional anxiety and inconvenience experienced by patients with premenstrual syndrome. Furthermore, excessive dependence on painkillers or long-term use can lead to side effects such as gastrointestinal or vascular disorders, making long-term use undesirable. Therefore, there is a need for the development of an agent for preventing, alleviating and treating premenstrual symptoms and menstrual pain that is highly effective and safe and can be administered for a long period of time.
[0005] In addition, women generally enter menopause around the age of 50 due to a rapid decline in ovarian function. As menopause continues, the secretion of the female hormone estrogen also decreases, resulting in an increased risk of developing menopausal symptoms such as osteoporosis, hyperlipidemia, facial hot flashes, breast cancer, and depression. Therefore, active research is being conducted on functional health foods and pharmaceuticals that can effectively regulate blood estrogen levels, which are important for the treatment and prevention of menopausal symptoms, as well as biomarkers related to menopausal women's diseases.
[0006] A study of menopausal women has shown that applying estrogen to the skin significantly improves elasticity, dryness, wrinkles, etc., making estrogen a powerful anti-aging substance that improves skin aging. However, these hormone ingredients have limitations in that they cannot be used as ingredients in products such as cosmetics, so there is a need to discover effective ingredients that can replace estrogen to improve the causes of menopausal skin aging.
[0007] Furthermore, hormone replacement therapies that have already been developed are known to have various side effects. For example, when estrogen is administered as hormone replacement therapy, it is known to carry risks such as endometritis, breast cancer, gallbladder disease, breast pain, mood changes, high blood pressure or thrombophlebitis, and weight gain. Therefore, it is not recommended for all menopausal women to undergo hormone replacement therapy, and some menopausal women are hesitant to try it or give up midway through.
[0008] Therefore, there is a pressing need to develop natural ingredients that can replace hormones to alleviate menopausal symptoms in women. [Prior art documents] [Patent documents]

The temperature of the sample was lowered to room temperature, and the filtered solution was distilled under reduced pressure to obtain 23g of a dark brown powder of a general notification type green tea extract (GT-LE-35CAT, sample 1) (yield 23%).
[0064] On the other hand, to prepare high-temperature processed green tea extract, 100g of green tea (Camellia sinensis, Osulloc Farm, Jeju Island) was added with 1000ml of 50% ethanol and stirred under reflux at 60°C for 1 hour. After concentrating, the extract was heated under steam at 1.5kgf / cm. 2 The mixture was stirred at RT for 1 to 7 hours. The temperature was then lowered to room temperature, and the insoluble material was filtered and concentrated under reduced pressure to obtain 10 g of high-temperature processed green tea extract. The high-temperature processed green tea extract obtained at each stirring time (1 to 7 hours) was measured for changes in the content of eight catechins using the equipment shown in Table 1 below. It was confirmed that the conversion of EGCG to GCG due to heat was at its highest at 5 hours, and that the amount of the eight catechins had not decreased any further. The 10 g of high-temperature processed green tea extract (HTP-GTE) obtained at this time was designated Sample 2.
[0065] The conditions and results of analyzing the compositions of the two extracts obtained are shown in Table 1 (composition analysis conditions for Samples 1 and 2), Table 2 (composition analysis results for Sample 1), and Table 3 (composition analysis results for Sample 2), respectively. The chromatograms for the two extracts are shown in Figures 1 (Sample 1) and 2 (Sample 2). That is, Sample 2 was confirmed to have a different composition from existing green tea extracts. Specifically, Sample 2 contained significantly lower amounts of EGCG (5.27 wt%), EGC (3.53 wt%), and total catechins (24.41 wt%) than Sample 1. However, it was confirmed that four epicatechin epimers, components not found in Sample 1, were also produced.

[0076] [Production Example 3] Production of theanine 10 kg of green tea leaves (Camellia sinensis, Osulloc Farm, Jeju Island) were extracted with hot water and then eluted with 1N sodium hydroxide (NaOH) using a cation exchange resin. The eluted solution was purified with activated carbon and eluted with 15% (v / v) ethanol (EtOH). It was then concentrated using an RO (reverse osmosis) membrane, purified by column chromatography, and crystallized to produce 24.8 g of L-theanine.
[0077] [Test Example 1] Evaluation of efficacy in improving premenstrual syndrome To evaluate the efficacy of the notified green tea extract, high-temperature-treated green tea extract, and theanine in improving premenstrual symptoms, 500 mg tablets containing 225 mg of Sample 1 (notified green tea extract), 225 mg of Sample 2 (high-temperature-treated green tea extract), 225 mg of Sample 3, and 225 mg of Sample 4 from Preparation Examples 1 and 2, and 12.5 mg of theanine from Preparation Example 3 were manufactured using a tabletop single-punch tablet press (ERWEKA, Germany). A control drug was also manufactured using the same method, except that 225 mg of maltodextrin (Target Corporation) was used.
[0078] According to the diagnostic criteria for premenstrual syndrome (Table 6), those with five symptoms, including one physical symptom, were considered to be in the premenstrual syndrome group. Of 88 women in their 20s to 50s of childbearing age, 60 were selected as study subjects. The 60 women were randomly divided into six groups, each with 10 participants: Sample 1 (publicly recognized green tea extract group), Sample 2 (high-temperature processed green tea extract group), Sample 3 (group), Sample 4 (group), theanine group, and control group (control drug group). Each group completed a premenstrual syndrome self-assessment questionnaire (Table 7) before their first menstrual period, and then took the appropriate tablets twice a day (two tablets per dose) for approximately four weeks until the end of their next menstrual period. That is, each group took 900 mg of the notified green tea extract (Sample 1), high-temperature processed green tea extract (Sample 2), Sample 3, and Sample 4 per day, and 50 mg of theanine per day. After the intake was completed, the subjects were asked to complete the self-questionnaire they had completed before their period again, and the average changes in total score and mood score were confirmed. The results are shown in Figure 3 (change in total score) and Figure 4 (change in mood score).
[0079] [Table 6]
[0080] [Table 7]
[0081] As shown in FIG. 3, it was confirmed that the subjects who ingested the high-temperature processed green tea extract of Sample 2 according to one embodiment of the present invention had a significantly reduced average total score compared to the subjects who ingested other notified green tea extracts, Samples 3 and 4, and the subjects who ingested theanine, an amino acid found in large amounts in green tea.
[0082] Furthermore, as shown in FIG. 4, regarding the mental symptoms (numbers 21 to 26) among the items in the questionnaire in Table 7, it was confirmed that the average score of the mental symptoms was significantly reduced in the subjects who ingested the high-temperature processed green tea extract of Sample 2 according to one embodiment of the present invention, compared to the subjects who ingested other notified green tea extracts, Sample 3, Sample 4, and the subjects who ingested theanine, an amino acid found in large amounts in green tea.
[0083] From the above results, it was confirmed that the high-temperature processed green tea extract of Sample 2 according to one embodiment of the present invention is very effective in alleviating or improving the physical and mental symptoms of premenstrual syndrome.
[0084] In particular, among samples 2 to 4, which are high-temperature processed green tea extracts, sample 2, which has a GCG:EGCG weight ratio of approximately 1:0.9, was confirmed to show a significant and excellent effect in alleviating or improving the physical and mental symptoms of premenstrual syndrome compared to samples 3 and 4, which have GCG:EGCG weight ratios of approximately 1:0.3 and 1:3, respectively.
[0085] [Test Example 2] Evaluation of efficacy in improving menopausal symptoms To evaluate the efficacy of the notified green tea extract, high-temperature-treated green tea extract, and theanine in improving premenstrual symptoms, 500 mg tablets containing 225 mg of Sample 1 (notified green tea extract), 225 mg of Sample 2 (high-temperature-treated green tea extract), 225 mg of Sample 3, and 225 mg of Sample 4 from Preparation Examples 1 and 2, and 12.5 mg of theanine from Preparation Example 3 were manufactured using a tabletop single-punch tablet press (ERWEKA, Germany). A control drug was also manufactured using the same method, except that 225 mg of maltodextrin (Target Corporation) was used.
[0086] The study subjects were 60 women with an average age of 50 years, who were pre- and post-menopausal and had a total score of 5 or higher on the menopausal symptom assessment scale (Table 8) below. These 60 women were randomly divided into six groups (10 women each). The study was conducted in the following groups: a group taking the designated green tea extract (Sample 1), a group taking high-temperature processed green tea extract (Sample 2), a group taking Sample 3, a group taking Sample 4, a group taking theanine, and a control group (control drug). The 60 women completed the menopausal symptom assessment scale (Table 8) below before taking each tablet, and then took two tablets twice daily for four weeks. Specifically, each group received 900 mg of designated green tea extract (Sample 1), high-temperature processed green tea extract (Sample 2), Sample 3, or Sample 4 daily, and 50 mg of theanine daily. After the end of the intake period, the menopausal symptom assessment scale was completed again to determine the average change in total score. The results are shown in Figure 5.
[0087] [Table 8]
[0088] As shown in FIG. 5, it was confirmed that the subjects who ingested the high-temperature processed green tea extract of Sample 2 according to one embodiment of the present invention had a significantly reduced average total score compared to the subjects who ingested other notified green tea extracts, Samples 3 and 4, and the subjects who ingested theanine, an amino acid found in large amounts in green tea.
[0089] These results confirmed that the high-temperature processed green tea extract of Sample 2 according to one embodiment of the present invention is highly effective in alleviating or improving the physical and mental symptoms of menopause.
[0090] Furthermore, among the high-temperature processed green tea extracts Samples 2 to 4, Sample 2, which has a GCG:EGCG weight ratio of approximately 1:0.9, was confirmed to exhibit significant and superior effects in alleviating or improving the physical and mental symptoms of menopause compared to Samples 3 and 4, which have GCG:EGCG weight ratios of approximately 1:0.3 and 1:3, respectively.
[0091] [Test Example 3] Evaluation of estrogen receptor activation efficacy To evaluate the efficacy of the notified green tea extract, high-temperature-treated green tea extract, and theanine in activating estrogen α and β receptors (ERα / β) at various GCG:EGCG weight ratios, Sample 1 (notified green tea extract), Sample 2 (high-temperature-treated green tea extract), Sample 3, Sample 4, and theanine from Preparation Example 3 were treated at concentrations of 20 μg / ml, 20 μg / ml, and 1 μg / ml, respectively, in a human ERα / β reporter assay panel (IB00421-48P, Indigo Bioscience) for 24 hours, and the level of increased activity of estrogen receptors ERα and ERβ was analyzed. 100 pM 17β-estradiol, which was included in the assay panel, was used as a positive control.
[0092] Specifically, the cells included in the human ERα / β reporter assay panel overexpress ERα and ERβ, respectively, and contain the ERE-luc reporter gene. When the activity of the estrogen receptor increases upon treatment with the test substance, ERα and ERβ bind to ERE and induce the expression of luciferase. The activity of ERα and ERβ can then be measured by measuring the level of luminescence emitted from the cells. The results are shown in Figure 6.
[0093] 6, when the activation level of estrogen receptors ERα and ERβ was analyzed by luciferase activity measurement, the notified green tea extract of Sample 1, Samples 3 and 4, and theanine treatment did not show any receptor activation effect, whereas the high-temperature-treated green tea extract of Sample 2 according to one embodiment of the present invention showed the effect of increasing the activity of estrogen receptors ERα and ERβ. This result indicates that the high-temperature-treated green tea extract according to one embodiment of the present invention can be effective in alleviating or improving premenstrual syndrome or menopausal symptoms by increasing the activity of estrogen receptors ERα and ERβ.
[0094] In particular, among samples 2 to 4, which are high-temperature processed green tea extracts, sample 2, which has a GCG:EGCG weight ratio of approximately 1:0.9, showed a significant effect of increasing the activity of estrogen receptors ERα and ERβ compared to samples 3 and 4, which have GCG:EGCG weight ratios of approximately 1:0.3 and 1:3, respectively, while samples 3 and 4 were confirmed to be at the same level as the remaining general, notified green tea extracts and theanine.
[0095] Furthermore, the results of Figure 6 confirmed that while 17b-estradiol, the positive control, increased the activity of both estrogen receptors ERα and ERβ to similar levels, the high-temperature-treated green tea extract of Sample 2 according to one embodiment of the present invention increased ERβ activity to a much greater extent than ERα. Activation of ERα increases breast cancer cell growth and cell division, leading to a higher incidence of breast cancer. However, since ERβ inhibits ERα activity and thus cancer cell growth, a higher increase in ERβ activity compared to ERα is expected to significantly reduce the risk of developing breast cancer, a known side effect of estrogen replacement therapy. Therefore, the following Test Example 4 was conducted to determine whether the high-temperature-treated green tea extract according to the present invention exhibits the side effect of promoting breast cancer cell growth.
[0096] [Test Example 4] Evaluation of growth inhibitory effect on MCF-7 breast cancer cell line MCF-7 cells (breast cancer cell line) obtained from the Korea Cell Line Bank were treated for 48 hours with the official green tea extract, high-temperature processed green tea extract, Sample 3, and Sample 4 (Preparation Example 1) at 20 μg / ml each, theanine (Preparation Example 3) at 1 μg / ml, and 17β-estradiol (100 pM) at 100 pM each, and then the cell number was measured using a cell counting device (Countess, Thermo Fisher Scientific). The results are shown in Figure 7.
[0097] As shown in Figure 7, 17b-estradiol, which was used as a positive control for estrogen receptor activation in Test Example 3, not only exhibited excellent ERβ activation efficacy but also significantly activated ERα to a similar extent, thereby significantly promoting the growth of MCF-7 breast cancer cells and causing significant side effects such as breast cancer development. In contrast, the high-temperature-treated green tea extract of Sample 2 according to one embodiment of the present invention did not exhibit such side effects and instead exhibited an effect of inhibiting the growth of MCF-7 cells.
[0098] Furthermore, in the case of Samples 3 and 4, which are high-temperature processed green tea extracts and have a GCG:EGCG weight ratio of approximately 1:0.3 and 1:3, respectively, it was confirmed that, as in Test Example 3, there was no significant effect on the activity of estrogen receptors ERα and ERβ, and therefore no significant effect on the growth of MCF-7 cells.
[0099] These results demonstrate that the high-temperature processed green tea extract of sample 2 according to one embodiment of the present invention exhibits excellent estrogen receptor activation efficacy without the side effects of existing estrogen replacement therapy, and may even be effective in preventing or treating breast cancer.
