Study on the Chemical Constituents from the Aerial Parts of Medicago sativa and Their Hypolipidemic Activity

Objective:To research the chemical constituents from the aerial parts of Medicago sativa.Methods:Various column chromatographies were emoployed to isolate and purify the constituents.Their structures were elucidated by spectral analysis(IR,UV,MS,1H-NMR,13C-NMR)and chemical evidence.Results:Two constituents were obtained and identified as soysaponinⅠ(Ⅰ),azukisaponin V(Ⅱ).Conclusion:These two compounds are isolated from the arial parts of Mesicago sativa for the first time.Moreover,the compounds are found to have hypolipidemic activity.
