The previously known astrailienin A and the new cycloartane glycoside cyclounifolioside B with structure cyclosiversigenin 3-O-[-D-glucopyranosyl(1-2)]--D-glucopyranoside were isolated from Astragalus unifoliolatus Bunge. The structures of these compounds were established using chemical transformations and two-dimensional spectra (ROESY, HMBC, HSQC, TOCSY, COSY). 相似文献

The known compound trojanoside A (1) and a new cycloartane glycoside cyclostipuloside E (2) were isolated from the aerial parts of Tragacantha stipulosa Boriss. The structure of cyclostipuloside E was proposed as 24R-cycloartan-3,6,16,24,25-pentaol 6,16,25-tri-O--D-glucopyranoside 3-O--D-xylopyranoside based. 相似文献

The new triterpene glycoside zygoeichwaloside G was isolated from the roots of Zygophyllum eichwaldii C.A.M. by column chromatography. Acid hydrolysis and PMR and 13C NMR spectroscopy using twodimensional COSY, TOCSY, and HSQC and analysis of HMBC and ROESY spectra established that glycoside G is 19--hydroxyursolic acid 3-O--L-(2-O-sulfo)-arabinopyranoside. 相似文献

Another seven components from the roots of Astragalus exilis A.Kor. (Leguminosae) were identified using spectral data and chemical transformations. A triterpenoid of genin nature was identical to cyclosiversigenin. One compound of glycosidic nature turned out to be a new cycloartane glycoside called by us cycloexoside B of structure 20R,24S-epoxycycloartan-3,6,16,25-tetraol 3-O--D-(2-Oacetyl) xylopyranoside. Five glycosides were identified as cyclosiversigenin 3-O--D-xylopyranoside and cyclosiversiosides B, C, D, and G. 相似文献
