A new secoiridoid glycoside, swertiapunimarin (I), was isolated from the whole plant of Swertia punicea Hemsl. The structure was elucidated as 6'-O-beta-D-glucopyranosylsweroside on the basis of chemical and spectroscopic analysis. The other seven known compounds were identified as sweroside (II), swertiamarin (III), oleanolic acid (IV), daucosterol (V), beta-sitosterol (VI), 2,3-dihydroxy-1,4-benzodicarboxylic acid (VII) and methylswertianin (VIII).
从紫红獐牙菜全草中分离得到一种新的裂环环烯醚萜苷，即獐牙菜苦苷（I）。通过化学和光谱分析，其结构被鉴定为6'-O-β-D-吡喃葡萄糖基獐牙菜苷。另外七种已知化合物被鉴定为獐牙菜苷（II）、獐牙菜苦苷（III）、齐墩果酸（IV）、胡萝卜苷（V）、β-谷甾醇（VI）、2,3-二羟基-1,4-苯二甲酸（VII）和甲基獐牙菜苷（VIII）。
