파 지하부로부터 분리된 2종의 diosgenin 배당체의 구조를 그의 분광학적 data와 화학적 실험 등의 방법으로 결정하였다. 그 결과, 이 두화합물의 구조는 diosgenin 3-O-$alpha$-L-rhamnopyranosyl (1$longrightarrow$2)-[$alpha$-L-rhamnopyranosyl (1$longrightarrow$4)]-$eta$-D-glucopyranoside (1, dioscin)과 diosgenin 3-O-$alpha$-L-rhamnopyranosyl (1$longrightarrow$4)-$alpha$-L-rhamnopyranosyl (1$longrightarrow$4)]- [$alpha$-L-rhamnopyranosyl (1$longrightarrow$2]-$eta$-D-glucopyranoside (2, saponin P-d)로서 기지 물질이나, saponin P-d를 부분가수분해하여 얻은 prosapogenin 중 compound 4는 문헌 미기재의 물질이다.
The structures of dioscin(1) and saponin P-d(2), isolated from the subterranean part of Allium fistulosum, were determined as diosgenin 3-O-$alpha$-L-rhamnopyranosyl (1longrightarrow2)-[$alpha$-L-rhamnopyranosyl (1longrightarrow4)]-$eta$-D-glucopyranoside (1, ) and diosgenin 3-O-$alpha$-L-rhamnopyranosyl (1longrightarrow4)-$alpha$-L-rhamnopyranosyl(1longrightarrow4)［$alpha$-L-rhamno-pyranosyl (1longrightarrow2)]-$eta$-D-glucopyranoside (2) by spectroscopic and chemical degradational methods. The prosa-pogenin(4), which was provided on partial hydrolysis of 2, was not reported in previous literature.
