不同规格枳实药材质量分析研究

目的对不同规格枳实药材进行系统的质量研究.方法采用HPLC法测定不同规格枳实中辛弗林含量,同时依照药典方法分别测定了其挥发油、总灰分、酸不溶性灰分和水分含量,对不同规格枳实药材进行综合质量对比研究,并与其传统规格分类进行比较.结果不同产地不同规格的枳实药材的总灰分、酸不溶性灰分、水分含量没有差异,总灰分含量均低于7%,符合<中国药典>中枳实项规定.不同规格枳实药材中挥发油含量和辛弗林含量有明显差异,其含量高低与传统等次划分相符.结论与现行药典标准中枳实项相比,本研究新增了酸不溶性灰分、水分、挥发油和辛弗林含量项,可更有效地评价枳实药材的质量,为枳实药材的商品流通和研究开发提供依据.

Quality Analysis of Different Specifications of Frutus Aurantii Immaturus

Objective To study the quality standard of different specifications of Frutus Aurantii Immaturus. Methods The contents of synephrine, volatile oil, total ash, acid- insoluble ash and water in different specifications of Frutus Aurantii Immaturus were determined by HPLC or other methods according the china pharmacopoeia. Results The contents of volatile oil and synephrine in different specifications of Frutus Aurantii Immaturus were obviously different, and in accordance with empirically traditional classification. The contents of the total ash, acid- insoluble ash and water were similar in the different specifications and the total ash content was lower than 7 % which was in accordance with that recorded in China Pharmacopoeia.Conclusion Volatile oil, acid- insoluble ash, water and synephrine with a definite content limit can be chosen as the parameters for the research of quality standard of Frutus Aurantii Immaturus, which will supply evidence for the medicinal trade and research of Frutus Aurantii Immaturus.
