Abstract

Three new pregnane glycosides, tinctorosides A–C (1–3, resp.), together with one known pregnane glycoside, stephanoside B (4), were isolated from the stems of Marsdenia tinctoria R. Br. (Asclepiadaceae). Their structures were elucidated by extensive spectral methods, especially 2D-NMR experiments (1H,1H-COSY, HSQC, HMBC, TOCSY, HSQC-TOCSY, and ROESY), and chemical evidence.
