Content Determination of Plumbagin in the Leaves of Plumbago zeylanica L. by Soxhlet Extraction with Different Solvents
摘要
Abstract
[Objective] To determine and compare the contents of plumbagin in the leaves of Plumbago zeylanica L. By different extraction methods, and to select the optimal extraction solvent. [ Method ] Soxhlet extraction method was adopted; plumbagin in the leaves of P. Zeylanica was extracted by different solvents. Its content was detected by HPLC, so as to select the optimal extraction solvent. [ Result] Contents of plumbagin extracted by chloroform, petroleum ether ( Ⅱ), 95% ethanol and anhydrous methanol were 0. 511% , 0. 341% , 0. 233% and 0.191%, respectively. Content of plumbagin in P. Zeylanica extracted by chloroform was the highest. [Conclusion] There were significant differences in the content of plumbagin in P. Zeylanica fresh leaves by different extraction methods.关键词
