摘要
目的对广东德庆产佛手犤CitrusmedicaL.var.sarcodactylis(Noot)Swingle犦进行系统化学研究,为建立其质量指标提供依据。方法利用层析和重结晶的方法从其乙醇提取物中分得3个化合物。结果经理化鉴定和光谱法分析确定3个化合物结构分别为柠檬内酯(Limittin)、△5,22-豆甾烯醇和棕榈酸。结论△5,22-豆甾烯醇为首次从佛手中分离得到。
Objective: To study the chemical components of Citrus medica L.var. sarcodactylis Swingle and to supply evidence for the quality control. Methods: Chromatography and recrystallization methods were applied to analyze the components. Results and Conclusion: Three compounds were extracted from Citrus medica L. var. sarcodactylis (Noot) Swingle. And their structures were identified as Limettin (I), stigmasta-5,22-dien-3-ol (II) and palmitic acid (III) by the methods of UV, MS, IR, 1HNMR, 13CNMR and DEPT. Stigmasta-5,22-dien-3-ol (II) was obtained by extraction.
