目的测定对比不同产地甘松中的挥发油及浸出物含量,为控制甘松药材的质量提供理论依据。方法参考《中国药典》附录中挥发油及浸出物测定方法。结果不同产地和不同采收期甘松挥发油含量存在差异,体积分数范围为2.0~5.2%(ml·g-1);采用稀乙醇作溶剂、热浸法的浸出物含量最高,且不同产地甘松浸出物含量也存在差异,含量范围为14.2%~37.7%。结论不同产地和不同采收期甘松中挥发油和浸出物含量差异较大,浸出物含量可以作为评价甘松药材质量的指标之一,该研究为完善甘松药材质量标准提供了一定的科学依据。
Objective To compare and contrast the contents of volatile oil and extract in kumiss pine from different habitats and to provide a theoretical basis for the quality control of kumyspora herbs. Method reference “Chinese Pharmacopoeia” Appendix volatile oil and extract determination. Results Volatile oil content in different producing areas and different harvesting periods varied with the volume fraction ranged from 2.0 to 5.2% (ml · g-1). With dilute ethanol as solvent, the content of volatile oil in hot-dip was the highest, There are also differences in the content of pine extract, the content range of 14.2% ~ 37.7%. Conclusion The content of volatile oil and extract in different producing areas and different harvesting periods are quite different. The content of extractables can be used as an index to evaluate the quality of the medicinal materials. The study provided some scientific evidences for improving the quality standard of Chinese medicines.
