Method of preparing ginseng saponine monomer from ginseng leaf

Abstract

A process for preparing ginsenoside monomer from ginseng leaf includes such steps as preparing general ginsenoside from ginseng leaf, chromatography with alumina column to obtain several groups of ginsenosides, and chromatography by column to obtain different ginsenoside monomers.

Description

technical field [0001] The invention relates to a method for extracting and separating various ginsenoside monomers from ginseng leaves, and more specifically discloses extracting and separating ginsenoside Rb from ginseng leaves 1 , Ginsenoside Rb 2 , Ginsenoside Rb 3 , Ginsenoside Rc, Ginsenoside Rd, Ginsenoside F 2 , Panax notoginsenoside Fe, ginsenoside Re, ginsenoside Rg 1 , Ginsenoside Rg 2 , Ginsenoside F 1 , especially extracting and separating ginsenoside F 1 , Ginsenoside F 2 1. The method of notoginseng saponin Fe belongs to the field of natural medicinal chemistry research. Background technique [0002] Ginseng leaves are the dried leaves of ginseng (Panax ginseng C.A.Mey.), harvested in autumn, dried or dried; it has the functions of invigorating qi, benefiting the lungs, dispelling heat, and promoting body fluid; it is used for cough due to qi deficiency, heat and irritability, and body fluid injury Thirst, blurred vision, tired limbs.
