epigynum auritum/glycoside

Chemical investigation of the stems of Epigynum auritum led to the isolation and identification of a novel 16,17-seco pregnane glycoside, epigynoside D, along with other three known compounds (2-4). The structure of compound 1 was elucidated by means of spectroscopic analysis, including HRESIMS, 1D

Phytochemical investigation on the leaves of Epigynum auritum led to the isolation of three novel C21 pregnane glycosides, epigynosides, E-G (1-3), together with two known pregnane glycosides, epigynosides A (4) and C (5). Their structures were elucidated based on extensive spectroscopic data (MS,

Five undescribed C₂₁ pregnane glycosides, epigycosides D-H, together with four known analogues, two lignans, and a flavonoid have been isolated from the stems of Epigynum cochinchinensis. The structures of pregnane glycosides were elucidated using spectroscopic techniques and acid

Chemical investigation on the aqueous fraction of the stems of Epigynum cochinchinensis led to the isolation of a new pregnane glycoside named as epigycoside A (1) along with three known analogues (2-4). The structure of compound 1 was elucidated by means of spectroscopic techniques, including

Phytochemical investigation on the ethyl acetate fraction of the leaves of Epigynum cochinchinensis led to the isolation of a new C21 pregnane glycoside, epigycoside B (1), together with three known analogues. Their structures were elucidated on the basis of extensive spectroscopic techniques,

A known compound and a new glycoside, epigeoside, were isolated from the rhizomes of Epigynum auritum (Schneid.) Tsiang et P. T. Li (Apocynaceae). The structure of known compound was identified as daucosterol (beta-sitosterol-beta-D-glucopyranoside). The structure of epigeoside has been deduced on
