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%.
