摘　　要：目的　分离并鉴定高原植物椭圆叶花锚 H alenia elliptica全草中的化学成分。方法　采用元素分析 (EA)、核磁共振波谱 (NMR)、质谱 (MS)、红外光谱 (IR)、紫外光谱 (U V)、差示扫描量热 (DSC)等分析方法 ,测定其理化常数和波谱数据 ,鉴定其化学结构。结果　确证从椭圆叶花锚中所得到的两种针状结晶化合物 ,分别为 1-羟基 - 3,7,8-三甲氧基酮 (1- hydroxy- 3,7,8- trimethoxyxanthone)和 1,7-二羟基 - 3,8-二甲氧基酮 (1,7- dihydroxy- 3,8-dimethoxyxanthone)。结论　上述两种酮衍生物为首次从藏药花锚中分离得到。Object To separate and characterize the chemical constituents of a plateau plant Halenia elliptica D Don Methods Elemental analysis (EA), 1HNMR and 13 CNMR, MS, FTIR and UV spectrometry, as well as DSC were employed Results Two needle shaped crystal chemical constituents obtained from H elliptica were confirmed to be 1 hydroxy 3, 7, 8 trimethoxyxanthone and 1, 7 dihydroxy 3, 8 dimethoxyxanthone, respectively Conclusion This is the first time for these two chemical constituents to be separated from this Tibetan medicinal plant
