A pregnane glycoside from the roots of Mandevilla pentlandiana

A pregnane triglycoside containing a new genin 3β,14β-dihydroxy-21-methoxy-5β-pregnan-20-one has been isolated from the dried roots of Mandevilla pentlandiana. Chemical and spectroscopic evidence for the glycoside are consistent with the structure 3β,14β-dihydroxy-21-methoxy-5β-pregnan-20-one-3-O- β...
