Novel dammarane-type glycosides from Gynostemma pentaphyllum.
Three new dammarane glycosides (1-3), together with five known compounds, gypenoside LXIX (4), gylongiposide I (5), gypenoside XLVIII (6), allantion (7) and vitexin (8) were isolated from the MeOH extract of the aerial parts of Gynostemma pentaphyllum. Compounds 5, 7, and 8 were isolated from this plant for the first time. Their structures were elucidated by 1D and 2D NMR spectra interpretation...
متن کاملNew dammarane-type glycosides from the roots of Gynostemma pentaphyllum.
Twelve new dammarane-type glycosides ( 1- 12) were isolated from the ethanol extract from the roots of a wild-type of Gynostemma pentaphyllum. The structures of the compounds were elucidated by 1D and 2D NMR spectroscopic analysis as well as by chemical degradation. The compounds contained six structurally diverse aglycons similar to those of the reported ginseng saponins with differences in th...
متن کاملDammarane-type triterpene saponins from the flowers of Panax notoginseng.
Four new dammarane-type triterpene saponins named floranotoginsenosides A (1), B (2), C (3) and D (4), together with five known triterpene saponins, were isolated from the flowers of Panax notoginseng. Their structures were elucidated on the basis of spectral and chemical evidence.
متن کاملSix new dammarane-type triterpene saponins from the leaves of Panax ginseng.
Six new minor saponins, together with known ginsenosides, were isolated from the leaves of Panax ginseng. The new saponins were named as ginsenoside-Rh5, -Rh6, -Rh7 -Rh8, -Rh9 and -Rg7, and their structures were elucidated on the basis of chemical and physicochemical evidence to be as follows: ginsenoside-Rh5: 3beta,6alpha,12beta,24zeta-tetrahydroxy-dammar-20(22),25-diene 6-O-beta-D-glucopyrano...
متن کاملIdentification of Major Saponins from Jiaogulan Extract (Gynostemma pentaphyllum)
Jiaogulan (Gynostemma pentaphyllum; GP) contained a saponin glycoside which was related to ginseng saponin. The purpose of this study was to identify the main saponin in water extract GP compared to methanol and ethanol extract. The sample was prepared by alkaline cleavage, trimethylsilyl (TMS) derivatization and gas chromatographic-mass spectrometric (GC-MS) analysis comparison with standard g...
