Two new compounds, along with two known compounds, were isolated from the barks of Parabarium huaitingii, and their structures were determined as 5α-pregn-6-ene-3β,17α,20(S)-triol-20-O-β-d-digitoxopyranoside (1), cymaropyranurolactone 4-O-β-d-digitalopyranosyl-(1 → 4)-O-β-d-cymaropyranosyl-(1 → 4)-O-β-d-oleandropyranosyl-(1 → 4)-O-β-d-cymaropyranoside (2), 3β,17α,20(S)-trihydroxy-5α-pregn-6-ene (3), and 5α-pregn-6-ene-3β,17α,20(S)-triol-3-O-β-d-digitalopyranoside (4) by spectroscopic methods.
从怀亭杜仲藤的树皮中分离出两种新化合物以及两种已知化合物，通过光谱方法确定它们的结构分别为5α-孕甾-6-烯-3β,17α,20(S)-三醇-20-O-β-D-洋地黄毒吡喃糖苷（1）、 cymaropyranurolactone 4-O-β-D-洋地黄吡喃糖基-(1→4)-O-β-D- cymaropyranosyl-(1→4)-O-β-D-夹竹桃吡喃糖基-(1→4)-O-β-D- cymaropyranoside（2）、3β,17α,20(S)-三羟基-5α-孕甾-6-烯（3）和5α-孕甾-6-烯-3β,17α,20(S)-三醇-3-O-β-D-洋地黄吡喃糖苷（4）。
