OBJECTIVE
To systematically study the chemical constituents in the roots of Gentiana dahurica.
METHODS
Various column chromatographic techniques were used for isolation and purification. The structures were elucidated on the basis of spectral data (UV, IR, MS, NMR) and identified by comparing with the authentic substance.
RESULTS
Seven compounds were isolated and identified as: roburic acid (1), oleanolic acid (2), beta-sitosterol (3), daucosterol (4), gentiopicroside(5), swertiamarine (6), sweroside (7).
CONCLUSION
Compounds 1, 2 and 4 are isolated from this plant for the first time.
目的
系统研究达乌里秦艽根中的化学成分。
方法
采用多种柱色谱技术进行分离纯化。根据光谱数据（紫外、红外、质谱、核磁共振）阐明结构，并与对照品比较进行鉴定。
结果
分离鉴定了7个化合物，分别为：蔷薇酸（1）、齐墩果酸（2）、β-谷甾醇（3）、胡萝卜苷（4）、龙胆苦苷（5）、獐牙菜苦苷（6）、獐牙菜苷（7）。
结论
化合物1、2和4首次从该植物中分离得到。
