Chemistry of Natural Compounds Aims and scope

Abstract

Orbicoside, a new lanostane glycoside and the first from plants of the Astragalus genus, was isolated from the aerial organs of Astragalus orbiculatus Ledeb. (Leguminosae). It has the structure 23ξ,24ξ-lanost-9(11)-en- 3β,7β,16β,19,23,24,25-heptaol 3-O-β-D-xylopyranoside. The structure of orbicoside was established using PMR and 13C NMR, which were interpreted using DEPT and 2D NMR spectroscopies 1H-1H COSY, HSQC, and HMBC.
