RESUMEN
Gentiana L. is the largest genera in Gentianaceae. Plants in Gentiana L. contain a lot of chemical constituents with pharmacological activities, especially iridoids. Iridoids has good hepatoprotective, anti-inflammatory, antipyretic, antiviral, and other pharmacological effects. This article summarizes the research progress of iridoids in plants from Gentiana L., which provide references for the studies of chemical constituents in Gentiana L. and the exploitation of medicinal resources.
RESUMEN
Objective To study the non-iridoid constituents from the roots of Gentiana straminea.Methods The compounds were repeatedly separated and purified on column chromatography of silica gel,Sephadex LH-20,and ODS,and their structures were identified on the basis of spectral and chemical methods.Results Twelve compounds were isolated from 70% ethanol extract of G.straminea and were identified as(-)-syringaresinol-4,4′-bis-?-O-D-glucopyranoside(1),gentiaphyllide-D(2),erythrecentaurin(3),macrophyiioside D(4),gentiaphyllide-E(5),roburic acid(6),uvaol(7),?-sitosterol(8),daucosterol(9),gentianose(10),?-glucose(11),and ?-glucose(12),respectively.Conclusion Compounds 1-6 and 10 are isolated from this plant for the first time.
