目的 研究蓖麻Ricinus communis根的化学成分。方法 利用硅胶柱色谱进行分离纯化，通过波谱方法鉴定化合物的结构。结果 从蓖麻根中分离并鉴定了14个化合物，分别为蓖麻三甘油酯（1）、3-乙酰氧基-油桐酸（2）、豆甾醇（3）、蓖麻碱（4）、3, 4-二羟基苯甲酸甲酯（5）、没食子酸（6）、油桐酸（7）、短叶苏木酚酸乙酯（8）、9-hydroxytridecyl docosanoate（9）、羽扇豆醇（10）、木犀草素（11）、棕榈酸（12）、二十八烷醇（13）、正十八烷（14）。结论 化合物1为新化合物，命名为蓖麻三甘油酯，化合物2、3、5～12和14为首次从蓖麻属植物中分离得到。

Objective To study the chemical constituents from the roots of Ricinus communis. Methods The chemical constituents were isolated and purified by silica gel column, and spectroscopic methods were used for the structural elucidation. Results Fourteen compounds were isolated and identified as ricintriglyceride (1), 3-acetoxyl-acid (2), stigmasterol (3), ricinine (4), methyl-3-dihydroxy benzoate (5), gallic acid (6), aleuritic acid (7), ethyl brevifolincarboxylate (8), 9-hydroxytridecyl docosanoate (9), lupeol (10), luteolin (11), palmitic acid (12), octacosanol (13), and octadecane (14). Conclusion Compound 1 is a new compound, named ricintriglyceride, and compounds 2, 3, 5—12, and 14 are isolated from the plants of Ricinus L. for the first time.
