[0057] Comparative Example 1

[0058] The difference from Example 3 is that Comparative Example 1 does not contain Artemisia quercetinus leaves and nettles, and the rest is the same as Example 3.

[0059] Comparative Example 2

[0060] The difference from Example 3 is that Comparative Example 2 does not contain Millettia spatholobi and Clematis spatholobi root, and the rest is the same as Example 3.

[0061] Comparative Example 3

[0062] The difference from Example 3 is that Comparative Example 3 does not contain geranium and liquorice, and the rest is the same as Example 3.

[0063] Comparative Example 4

[0064] The difference from Example 3 is that Comparative Example 4 does not contain peach branches and polygonatum odoratum, and the rest is the same as Example 3.

[0065] 1. Malassezia inhibition ring test:

[0066] Test principle: Malassezia is one of the main pathogens that cause dandruff and itching.

[0067] The Malassezia inhibition ring was tested to determine whether the compositions of Examples 1 to 4 and Comparative Examples 1 to 4 had an antipruritic effect.

[0068] Test method: The ambient temperature is 18℃~25℃, and the ambient humidity is 30%~70%. The sterile filter paper with the test sample is placed on the stained Malassezia plate and cultured in an incubator at 30℃ for 3-7 days; the diameter of the Malassezia inhibition ring is measured with a ruler. If the diameter of the inhibition ring is greater than 7mm, it can be considered that the test sample has a certain antipruritic effect. The results of the Malassezia inhibition ring test are shown in Table 1.

[0069] Table 1 Malassezia inhibition ring test results

[0070] sample Diameter of antibacterial ring / mm Antipruritic effectiveness Example 1 10.3 efficient Example 2 13.9 efficient Example 3 15.2 efficient Example 4 11.5 efficient Comparative Example 1 <7.0 invalid Comparative Example 2 <7.0 invalid Comparative Example 3 7.6 efficient Comparative Example 4 7.8 efficient

[0071] Examples 1 to 4 have a good inhibitory effect on Malassezia, and the diameter of the antibacterial ring is all above 10 mm, among which Example 3 has the best antibacterial effect; Comparative Example 1 does not contain a monarch drug, and has no inhibitory effect on Malassezia; Comparative Example 2 does not contain a ministerial drug, and has no inhibitory effect on Malassezia; Comparative Example 3 does not contain an adjuvant drug, and has an inhibitory effect on Malassezia, but its antibacterial ring is far different from that of Example 3; Comparative Example 4 does not contain a messenger drug, and has an inhibitory effect on Malassezia, but its antibacterial ring is also far different from that of Example 3. It can be seen that compared with Comparative Examples 1 to 4, Example 3 uses the traditional Chinese medicine theory of monarch, minister, assistant and messenger, and the oil-control and antipruritic composition prepared with Artemisia quercetinus leaves, nettles, Millettia spatholobi, stinking peony root, geranium, peach twig, licorice, and Polygonatum odoratum can play a synergistic effect.

[0072] 2.5α-reductase inhibition test

[0073] Test principle: 5α-reductase can convert testosterone into dihydrotestosterone (androgen), which will affect the excessive secretion of oil by the sebaceous glands. The oil control effect of the compositions of Examples 1 to 4 and Comparative Examples 1 to 4 is determined by detecting the inhibition rate of 5α-reductase.

[0074] Test method: Add a blank control solution (100 μL of 0.5 mg / ml testosterone, 200 μL of phosphate buffer, 15 μL of 1 mg / ml reduced coenzyme II tetrasodium salt solution) to the reaction tube, then add 15 μL of 150 mg / ml 5α-reductase, mix and incubate at 37°C, and measure the A340nm value after 60 minutes (blank control sample A1).

[0075] A blank control solution and 50 μL of 0.1% finasteride solution were added to the reaction tube, and finally 15 μL of 150 mg / ml 5α-reductase was added, mixed and incubated at 37° C. for 60 min, and then the A340nm value was measured (finasteride control sample A2).

[0076] A blank control solution and 50 μL of the composition of Examples 1 to 4 or Comparative Examples 1 to 4 were added to the reaction tube, and then 15 μL of 150 mg / ml 5α-reductase was added, mixed and incubated at 37° C. for 60 min, and then the A340nm value was measured (test sample A2).

[0077] The calculation formula of 5α-reductase inhibition rate is: A1: absorbance of blank control sample; A2: absorbance of sample. The test results of 5α-reductase inhibition rate are shown in Table 2.

[0078] Table 2 5α-reductase inhibition test results

[0079]

[0080]

[0081] Examples 1 to 4 have a good inhibitory effect on 5α-reductase, with an inhibition rate higher than 39.87%, which is almost more obvious than the inhibitory effect of finasteride on 5α-reductase. Compared with comparative examples 1 to 4, the oil-controlling and antipruritic composition of Example 3, which is compounded with Artemisia argyi leaves, nettles, Millettia spatholobi, Cryophyllum scabra, Pelargonium graveolens, peach branches, licorice, and Polygonatum odoratum, has a significantly improved inhibitory effect on 5α-reductase, and can play a synergistic role.

[0082] 3. User Testing

[0083] Test sample: The compositions of Examples 1 to 4 and Comparative Examples 1 to 4 were prepared into shampoos at an addition amount of 5%.

[0084] Test subjects: 40 volunteers aged 18 to 50 years old with itchy scalp and greasy hair problems, 5 people for each embodiment and comparative example.

[0085] Test steps: Volunteers used shampoo to wash their hair every day in the same process and method, with the amount used each time being 5g to 10g. After 28 days of use, the volunteers were subjected to sensory evaluation and the average score of each item was calculated. The sensory evaluation results are shown in Table 3.

[0086] Oil control effect evaluation criteria: 1 point - very greasy, 2 points - very greasy, 3 points - relatively greasy, 4 - slightly greasy, 5 points - not greasy.

[0087] Evaluation criteria for antipruritic effect: 1 point - frequent severe itching, 2 points - frequent itching, 3 points - occasional itching, 4 points - mild itching, 5 points - no itching.

[0088] Irritation evaluation criteria: 1 point - severe irritation, 2 points - moderate irritation, 3 points - mild to moderate irritation, 4 points - mild irritation, 5 points - no irritation.

[0089] The evaluation criteria for preference are: 1 point - very disgusted, 2 points - relatively disgusted, 3 points - neither disgusted nor liked, 4 points - relatively liked, 5 points - very much liked.

[0090] Table 3 Sensory evaluation results

[0091]

[0092]

[0093] Examples 1 to 4 are significantly better than Comparative Examples 1 to 4 in terms of oil control effect, antipruritic effect and likability, indicating that the shampoos prepared from the oil control and antipruritic compositions of Examples 1 to 4 better meet the user's shampooing needs and are more popular with users.

[0094] The present invention utilizes the theory of monarch, minister, assistant and envoy of traditional Chinese medicine, and prepares the oil-controlling and antipruritic composition by compounding Artemisia quercetinii leaves, nettles, Millettia spatholobi, stinking peony root, geranium, peach twig, licorice and Polygonatum odoratum through the above preparation method, wherein Artemisia quercetinii leaves and nettles are used as monarch drugs to ensure a strong oil-controlling and antipruritic effect, enhance scalp immunity, reduce scalp oil secretion and relieve itching; Millettia spatholobi and stinking peony root are used as assistant drugs to improve the heat-clearing and detoxifying and active blood-stasis-removing abilities of the composition, assist the monarch drug in resisting damp-heat and inflammation, and enhance the oil-controlling and antipruritic effects; and Geranium and peach twigs are used as adjuvants to soothe and relax the scalp and improve the blood circulation between the scalp muscles, thereby assisting the main medicine in improving the health of the scalp; licorice and polygonatum are used as guiding medicines to moisturize the scalp, harmonize the medicinal properties of the group of medicines, enhance the overall efficacy of the group of medicines, and have a significant inhibitory effect on Malassezia and 5-α reductase; ethanol and water are used for temperature-controlled extraction respectively to effectively extract the volatile or water-insoluble active ingredients of the Chinese medicine raw materials, so that the active ingredients are synergistically enhanced; at the same time, the preparation method is simple, does not require special equipment, and is suitable for industrial production.
