Annotation

Three renowned compounds cycloartane series are highlighted from aboveground organs Тrаgасапthа stiриlоsа Воriss– cyclosiversiosides Е and F, cyclonifolioside В and a new glycoside - cyclostipuloside D that has structure 3-О-b-О- glucopyranoside, 6-О-b-D- xylopyranoside -20R, 24S- epoxycycloartan -3b,6a,16b,25- tetraola. Structure of glycosides is determined based on NMR spectra 1Н and 13С interpreted with 2М NMR – spectroscopy 1Н-1Н COSY, ROESY, TOCSY, HSQC, HMBC
