New pregnane glycosides from Sinomarsdenia incisa.
Five new pregnane glycosides, sinomarinosides A (1), B (2), C (3), D (4), and E (5), have been isolated from Sinomarsdenia incisa (Asclepiadaceae). The structures of these compounds were elucidated by NMR and mass spectroscopic methods and chemical evidence.
