YANG Ai-mei, HAN Han, SUN Jing, et al. Chemical Constituents from Gentiana algida[J]. Chinese journal of experimental traditional medical formulae, 2011, 17(19): 121-124. DOI: CNKI:11-3495/R.20110809.1706.019.
Objective: To isolate and identify chemical constituents from Gentiana algida collected from Qinghai province. Method: The chemical constituents were isolated by column chromatography and their structures were elucidated through NMR
MS and IR. Result: Eleven compounds were isolated and identified as β-sitosterol(1)
β-amyrin(2)
ursolic acid(3)
oleanolic acid(4)
24-hydroxyl- β- amyrin(5)
28-hydroxyl-α-amyrin(6)
28-hydroxyl- β-amyrin(7)
pseudotaraxasterol(8)
pseudotaraxasterol-3 β- O -palmitate(9)
3 β-palmitate-28-hydroxyl-α-amyrin(10)
3 β-palmitate-28-hydroxyl- β-amyrin(11). Conclusion: All these compounds are obtained from G. algida for the first time.
