目的：对黄花败酱根及根茎的化学成分进行研究。方法：用化学法和光谱法分离、鉴定其成分。结果：从干燥根及根茎中分得４ 个皂苷类化合物，分别为常春藤皂元３Ｏβ（２′乙酰基）吡喃阿拉伯糖苷，齐墩果酸２８ＯβＤ吡喃葡萄糖苷，常春藤皂苷元３ＯαＬ吡喃阿拉伯糖（１ →３）βＤ吡喃木糖苷，齐墩果酸３ＯαＬ吡喃鼠李糖（１→２）βＤ吡喃木糖苷。结论：均为首次从该植物中获得。 Objective: To study the chemical constituents of roots and rhizomes of P. vulgaris. Methods: Chemical components and spectroscopic methods were used to separate and identify the components. Results: Four saponins were isolated from the dried roots and rhizomes. They were Ivy-3  O  β  (2′  acetyl) - arabinopyranoside, oleanolic acid  28  O βDglucopyranoside, ivy saponin3OαLarabinose (1→3)βDxylopyranoside, oleanolic acid3O ααL-rhamnopyritol (1→2)βD-pyroxyloside. Conclusion: All were obtained from this plant for the first time.
