Abstract

This invention discloses resurrection lily rhizome glycoside distilling from light leaf small la tree. The tree flower and leaf powder is got and distilled by water three times, then extracting solution is united and concentrated, ethanol is added until its content reaches 80 percent, filtrated and precipitation is abandoned. The filtrate is decompressed and the solvent is recovered, then 40 percent ethanol solvent is used to dissolve it, staying and filtrating after recrystallization, and the crystallization is abandoned. The mother liquor is decompressed and distilled by normal butyl alcohol 4 times, the normal butyl alcohol liquor is united, and solvent is recovered to few quantity, staying and recrystallization, and that is crude resurrection lily rhizome glycoside. It is recrystalled by ethanol to get yellow needle crystal, and that is the resurrection lily rhizome glycoside. This invention is simple and practical, and its material cost is cheap, its resurrection lily rhizome glycoside content is tested between 2.86 mg / g and 9.25mg / g, it can provide abundant material and simpole distillation method for resurrection lily rhizome glycoside and its derivative.

Description

technical field

[0001] The invention relates to a method for extracting and separating active ingredients of natural plants in the pharmaceutical industry, and in particular to a method for extracting and separating kaempferrin from S. glabrata. Background technique

[0002] L. sinense Lour var nitidum Ruhd is a plant of Oleaceae Oleaceae Ligustrum Linn. It is an evergreen shrub and is recorded in "Dictionary of Chinese Medicine" [1] Zhong, also known as water white wax, has a flat taste and slightly bitter taste, and has the functions of clearing heat and reducing fire, and is used to treat hematemesis, toothache, aphtha, sore throat, damp heat, yellow water to nourish sores, etc. The research on chemical composition shows that it mainly contains alkanes, higher fatty alcohols, steroids, triterpenoids and flavonoids, among which the content of kaempferol is relatively high.

[0003] Kaempferitrin is a flavonoid compound (C 27 h 30 o 14 , molecula...
