OBJECTIVE
To study the chemical constituents of Geranium eristemon.
METHOD
Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures.
RESULT
Five compounds were isolated from acetone extract of the whole grass of G. eristemon, and identified as beta-sitosterol, protocatechuic acid, myricetin, kaempferol-7-O-alpha-L-arabifuranoside and kaempferol-3-O-alpha-L-arabifuranoside.
CONCLUSION
kaempferol-7-O-alpha-L-arabifuranoside and kaempferol-3-O-alpha-L-arabifuranoside were isolated from G. genus for the first time.
目的
研究滇西老鹳草的化学成分。
方法
采用色谱法和光谱分析法分离化合物并鉴定其结构。
结果
从滇西老鹳草全草的丙酮提取物中分离得到5个化合物，分别鉴定为β-谷甾醇、原儿茶酸、杨梅素、山柰酚-7-O-α-L-阿拉伯呋喃糖苷和山柰酚-3-O-α-L-阿拉伯呋喃糖苷。
结论
山柰酚-7-O-α-L-阿拉伯呋喃糖苷和山柰酚-3-O-α-L-阿拉伯呋喃糖苷为首次从老鹳草属植物中分离得到。
