目的 对西藏雪莲花(Saussurea tridac-tyla Sch-Bip)全草化学成分进行分离鉴定。方法 用色谱技术进行分离，UV，IR，EIMS，FABMS，ESIMS，¹H-NMR和¹³C-NMR等光谱方法对化合物结构进行鉴定。结果 从西藏雪莲花全草的乙醇提取物中分离得到4个化合物，分别鉴定为对羟基苯甲酸(p-hydroxy benzonic acid Ⅰ)、胡罗卜苷(daucosterol Ⅱ)、金合欢素-7-O-β-D-芦丁糖苷(acacetin-7-O-β-D-rutinoside Ⅲ)和伞形花内酯-7-O-β-D-葡萄糖苷(umbeliferone-7--O-β-D-glucoside Ⅳ)。结论 化合物Ⅰ～Ⅳ首次从该植物中得到，化合物Ⅲ首次从该属植物中得到。

OBJECTIVE To separate and identify the chemical constitutes of the whole plant of Saussurea tridac-tyla Sch-Bip.METHODS The compounds were separated with chromatographic technology and their chemical structures were elucidated with UV,IR,MS,¹H-NMR and ¹³C-NMR spectral methods.RESULTS Four compounds were isolated from the plant.They were identified as p-hydroxy benzonics acids(Ⅰ),daucosterol(Ⅱ),acacetin-7-O-β-D-rutinoside(Ⅲ) and umbeliferone-7-O-β-D-glucoside(Ⅳ),respectively.CONCLUSION These compounds were isolated from the plant for the first time,and the compound Ⅲ was isolated from this genus for the first time.
