[Saponins from roots of Hedysarum multijugum].Zhongguo Zhong Yao Za Zhi. 2007 Feb; 32(4):315-7.ZZ
To study the chemical constituents from the root of Hedysarum multijugum.
The compounds were separated by chromatographic methods, their structures were identified by spectral analysis.
Four compounds were isolated and identified as soyasaponin II methyl ester (1), soyasaponin II (2), soyasaponin Bg (3), and soyasaponin I (4).
The four compounds were obtained from the plant for the first time. Compound 3 was isolated from the genus Hedysarum for the first time, and the NMR data of 3 was reported for the first time.
