OBJECTIVE
To study the chemical constituents of Viola tianshanica.
METHOD
Compounds were isolated by silica column, pharmadex LH-20 column and polyamide column, and their structures were elucidated by UV, IR, ESI-MS and NMR.
RESULT
Six compounds were isolated and identified as daucosterol (1), kaempferol-7-O-beta-D-glucopyranoside (2), kaempferol- 3-O-beta-D-glucopyranoside (3), isorhamnetin-3-O-beta-glucoside (4), kaempferol (5) and quercetin (6).
CONCLUSION
Compounds 2-5 were isolated from this plant for the first time.
目的
研究天山堇菜的化学成分。
方法
采用硅胶柱、葡聚糖凝胶LH - 20柱和聚酰胺柱进行化合物分离，通过紫外光谱（UV）、红外光谱（IR）、电喷雾电离质谱（ESI - MS）和核磁共振（NMR）对其结构进行鉴定。
结果
分离鉴定出6个化合物，分别为胡萝卜苷（1）、山柰酚 - 7 - O - β - D - 吡喃葡萄糖苷（2）、山柰酚 - 3 - O - β - D - 吡喃葡萄糖苷（3）、异鼠李素 - 3 - O - β - 葡萄糖苷（4）、山柰酚（5）和槲皮素（6）。
结论
化合物2 - 5首次从该植物中分离得到。
