Embodiment 1

[0123] Example 1 Vitex vitex coarse powder 1kg, soaked in 2000ml of extraction solvent 60% ethanol, left overnight, percolation according to the routine, control percolation speed 3 ~ 5ml / min, add extraction solvent at any time during percolation process, percolation to The percolate is collected until the test reactions of flavonoids and terpenoids are negative. The percolation solution was recovered under reduced pressure until there was no ethanol smell, diluted with distilled water to 1000ml, filtered to remove suspended solids and insoluble impurities, and adjusted to a relative density of 1.05 with distilled water. Pass the above filtrate through D 101 Macroporous adsorption resin, wash with water to remove inactive components such as water-soluble sugars and soluble hemicelluloses in the filtrate, wash away non-flavonoid soluble substances with 15% ethanol, then elute with 40% ethanol as the eluting solvent, and collect the eluate , recovered the solvent to 250ml, and ...

Embodiment 2

[0124] Example 2 The extraction solvent was 20% methanol, and the rest was the same as in Example 1 to obtain VT-16.07g with a flavonoid content of 31.20%.

Embodiment 3

[0125] Example 3 The extraction solvent was 95% ethanol, and the rest was the same as in Example 1 to obtain 9.07 g of VT-1 with a flavonoid content of 74.54%.

Abstract

Two extracts VT-1 and VT-2 of shrub chastetree fruit for treating periodic mastodynia, menalgia and premenstrual syndrome is prepared through extracting in mixture of water and methanol or ethanol, separating by adsorptive resin to remove impurities, and eluting by the aqueous solution of alcohol with different concentrations.

Description

technical field [0001] The present invention relates to the technical field of medicine, and consists of two extracts prepared from Vitex vitae as raw materials, one is VT-1 rich in flavonoids, and the other is VT-2 containing both flavonoids and terpenoids , and the application of VT-1 and VT-2 in the preparation of medicines and foods for preventing and treating premenstrual syndrome and diseases closely related to premenstrual syndrome. Background technique [0002] Premenstrual syndrome (Premenstrual Syndrome, PMS) and its closely related diseases such as periodic mastalgia, dysmenorrhea, etc. are common and frequently-occurring diseases in women, and a survey shows that more than 90% of women will experience symptoms 7 to 14 days before menstruation. Different degrees of irritability, malaise, breast pain, headache, insomnia, lower abdominal pain, blunt low back pain and pelvic heaviness, edema, epigastric pain, nausea and vomiting, memory loss, work d...
