Resumen:
A pregnane triglycoside containing a new genin has been isolated from the dried roots of Mandevilla pentlandianu. Chemical and spectroscopic evidence for the glycoside are consistent with the structure 38,14B-dihydroxy-21-methoxy-5B-pregnan-20-one-3-O-B-D-diginopyranosyl-( 1+4)-O-/I-D-cymaropyranosyl-( 1+4)-0-B-D-cymaropyranoside. It is noteworthy that 38,148, 21-trihydroxy SB-pregnan-20-one, biosynthetically related to the genin of this glycoside, has been proved to be a precursor of cardenolides, alsoproduced by this plant.
