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 of Ricinus communis roots. Methods The compounds were separated and purified by silica gel column chromatography and identified by spectroscopic methods. Results Fourteen compounds were isolated from castor root and identified as castor bean triglyceride (1), 3-acetoxy-tungstolic acid (2), stigmasterol (3), ricinine Methyl gallate (5), gallic acid (6), tartaric acid (7), ethyl fumarate (8), 9-hydroxytridecyl docosanoate 10), luteolin (11), palmitic acid (12), octacosanol (13) and n-octadecane (14). Conclusion Compound 1 is a new compound named as castor triglyceride. Compounds 2,3,5 ~ 12 and 14 were isolated from castor for the first time.
