ABSTRACT

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.
