An ethanol extract of Baileya pauciradiata exhibited cytotoxic activity against the human epidermoid carcinoma of the nasopharynx and the lymphocytic leukemia test systems. Two constituents responsible for this activity were isolated and identified as odoratin and paucin. Their identities were proven by IR, PMR, and mass spectral data; elemental analysis; preparation of their acetates; and melting-point determinations. Odoratin was confirmed by comparison with an authentic sample.
少花百日菊的乙醇提取物对人鼻咽癌和淋巴细胞白血病测试系统表现出细胞毒性活性。分离并鉴定了导致这种活性的两种成分，分别为少花百日菊素和少花苷。通过红外光谱、核磁共振氢谱、质谱数据、元素分析、制备它们的醋酸酯以及熔点测定来证实它们的结构。通过与标准样品比较确认了少花百日菊素。
