Study on Chemical Constituents from Roots of Psychotria rubra
摘要
Abstract
Objective:To study the chemical constituents from the roots of Psychotria rubra.Methods:The roots of Psychotria rubra were extracted with 80％ ethanol for reflux,and the extracts were evaporated.Eight compounds were isolated by D101 macroporous resin,silica gel chromatography,ODS C18 and Sephadex LH-20 column chromatography from water part of extracts.Their structures were identified on the basis of physico-chemical characters and spectroscopic analysis.Results:Eight compounds were obtained from the roots from Psychotria rubra,and identified as asperulosidic acid (1),6-methoxygeniposidic acid(2),6α-hydroxygeniposide (3),deacetylasperulosidic acid(4),asperuloside (5),sucrose (6),1-O-acetyl-β-D-galactopyranose (7) and 1-O-acetyl-β-D-glucoside (8).Conclusion:Compounds 1,2,4,5 are isolated from Psychotria rubra for the first time,compounds 2,4 are isolated from Psychotria genus for the first time.关键词
