Abstract A comprehensive phytochemical research on roots of Caragana grandiflora, a native plant to Iran, resulted in isolation of ten compounds including four phenolic compounds (2, 4, 5, 8), two fatty alcohols (1, 6), one fatty acid (9), one triterpene (3), one glyceride derivatives (7) and one fatty acid methyl ester (10), from which eight compounds (1, 2, 4–6 and 8–10) were isolated from the genus Caragana and two compounds (5 and 10) from the family Fabaceae, for the first time. All compounds (1–10) were described from Caragana grandiflora for the first time. Chemical structures of the purified compounds were identified through FT-IR, NMR and MSS, and spectral data comparison with literature reported evidences. Our findings provide valuable information in reporting the rare existence of natural fatty acid methyl ester (10) in the Fabaceae family. Moreover, the chemotaxonomic significance of these compounds was discussed.

摘要 对伊朗本土植物 Caragana grandiflora 根的综合植物化学研究结果分离出 10 种化合物，包括四种酚类化合物 (2, 4, 5, 8)，两种脂肪醇 (1, 6)，一种脂肪酸 ( 9)、一种三萜 (3)、一种甘油酯衍生物 (7) 和一种脂肪酸甲酯 (10)，从中分离出 8 种化合物（1、2、4-6 和 8-10）来自 Caragana 属和两种首次从豆科植物中分离出化合物（5 和 10）。所有化合物 (1-10) 都是首次从 Caragana grandiflora 中描述。纯化化合物的化学结构通过 FT-IR、NMR 和 MSS 以及光谱数据与文献报道的证据进行比较。我们的发现为报告豆科植物中罕见的天然脂肪酸甲酯 (10) 的存在提供了有价值的信息。此外，还讨论了这些化合物的化学分类学意义。
