摘要
Two new compounds, along with two known compounds, were isolated from the barks of Parabarium huaitingii, and their structures were determined as 5 alpha-pregn-6-ene-3 beta,17 alpha,20(S)-triol-20-O-beta-D-digitoxopyranoside (1), cymaropyranurolactone 4-O-beta-D-digitalopyranosyl-(1 -> 4)-O-beta-D-cymaropyranosyl-(1 -> 4)-O-beta-D-oleandropyranosyl-(1 -> 4)-O-beta-D-cymaropyranoside (2), 3 beta,17 alpha,20(S)-trihydroxy-5 alpha-pregn-6-ene (3), and 5 alpha-pregn-6-ene-3 beta,17 alpha,20(S)-triol-3-O-beta-D-digitalopyranoside (4) by spectroscopic methods.
