Abstract Phytochemical study of Glycyrrhiza pallidiflora Maxim. gave seventeen compounds, including two sterols (3 and 4), four triterpenes (1, 2, 5, 6), ten flavones (7, 9–17), and one pterocarpan (8). The chemotaxonomic significance of G. pallidiflora was discussed, which indicated the close relationship between G. pallidiflora with other species of Glycyrrhiza. Moreover, pallidiflorin can be served as a fingerprint for G. pallidiflora, macedonic acid and echinatin can be recognized as biomarkers for Glycyrrhiza, while formononetin, afrormosin and calycosin may be typical second metabolites for Papilionoideae.

白花甘草化学成分及化学分类学研究

摘要 甘草的植物化学研究。得到了 17 种化合物，包括两种甾醇（3 和 4）、四种三萜（1、2、5、6）、十种黄酮（7、9-17）和一种紫檀木 (8)。讨论了G. pallidiflora的化学分类学意义，表明G. pallidiflora与其他甘草属植物的亲缘关系密切。此外，苍白菊素可作为苍白菊科的指纹，马其顿酸和紫锥菊素可被认为是甘草的生物标志物，而芒柄花素、无毛花素和毛蕊花素可能是凤蝶科典型的第二代谢产物。
