微粉化对丹参质量影响的研究

Effect of Micronization on the Quality of Salvia miltiorrhiza Bge.

目的:比较丹参普通粉和微粉的粉体学特征、水溶性浸出物含量、指标成分隐丹参酮、丹参酮ⅡA及原儿茶醛提取率,探索微粉化技术在丹参中的应用价值。方法:通过激光粒度分析仪对普通粉和微粉进行表征,扫描电镜(SEM)观察普通粉和细粉的表面形态,测定粉体学参数休止角和堆密度,热浸法测定水溶性溶出物的含量,加热回流分别提取隐丹参酮、丹参酮ⅡA及原儿茶醛,采用HPLC测定它们的含量。结果:丹参普通粉和微粉的粉体学特征及表面形态差异显著,水溶性浸出物微粉为普通粉的1.23倍,隐丹参、丹参酮ⅡA及原儿茶醛分别为普通粉的1.54、1.48、1.90倍。结论:丹参微粉化既能提高脂溶性成分隐丹参酮和丹参酮ⅡA的提取率,又能提高水溶性成分原儿茶醛的提取率,表明丹参药材利用微粉化技术能提高药材的利用率,减少药材的使用量,从而达到节省药材资源的目的。

Objective： The powder characteristic, water extraction amount and active ingredients cryptotanshinone （CTS）, tanshinone Ⅱ A （TS） and protocaechuic aldehyde （PA） were comparatively studies between crude powder and micronized powder to study the application of micronization technology to Salvia miltiorrhiza Bge. Methods ： Salvia miltiorrhiza Bge powedr was characterized by laser diffraction analyzer and scanning electron microscopy, the angle of repose and bulk density was measured. The water extraction was quantified by heated extraction method. The active ingredinents CTS, TS and PA were detected by RP-HPLC after it released from Salvia miltiorrhiza Bge. Results： The differences of particle characteristic and surface modality between crude powder and superfine were significant. Water extraction amount of micronized powder was 1.23 times as that of crude powder. The CTS, TS and PA extraction amount of micronized powder were 1.54,1.48 and 1.90 times as those of crude powder. Conclusion： The extraction content of lipo-solubility and water-solubility active ingredients of Salvia miltiorrhiza Bge. are improved by micronization. Micronization can economize the resource of Salviae miltiorrhiza Bge. The bioavability of Salviae miltiorrhiza Bge. will be improved with the new techonology.
