摘要

目的 :比较当归超微粉体和普通粉体的粉体学性质

为超微粉粹应用于当归提供试验依据。方法 :通过测定当归粉体的粒径及分布、吸湿性、粉体的形貌结构等粉体学特征和体外溶出行为

研究当归粉体的粒径对其粉体学特性、含量和体外溶出行为的影响。结果 :随当归粉体粒度的减小

比表面积及孔容和吸湿性增加

流动性变弱

4种粉体中阿魏酸含量大小顺序为普通粉＞微粉Ⅰ＞微粉Ⅱ＞微粉Ⅲ

但是随着粉碎程度的加强

微粉Ⅱ中的阿魏酸溶出速率、累积溶出率和溶出总量均高于其它粒径级别的当归粉体。结论 :适度的微粉化能促进当归有效成分的溶出。

Abstract

Objective: To compare the powder properties between common powder and micropowders of Angelica to provide experimental evidence for the superfine grinding application. Method: Morphology structure

hygroscopic property

liquidity

surface area and porosity of Angelica powders were investigated; the contents and the dissolution of ferulic acid of Angelica powders were determined by HPLC. Result : With the decreasing of particle size of powders

the surface area

pore volume and moisture increased

and the liquidity decreased; the contents of ferulic acid from four Angelica powders were in the order of: common powder > ultrafine powder I > ultrafine powder II > ultrafine powder III; but with the crushing level increased

dissolution rate and the total dissolution of the ultrafine powder II was higher than levels of particle size in other angelica powder. Conclusion : An appropriate degree of micronization is helpful for the dissolution of the active components in Angelica.
