天麻细胞级微粉碎和普通粉碎质量标准对比实验研究

The experimental studies on quality standard of cellular level and ordinary pulverization for Gastrodia elata BL.

目的 :比较天麻细胞级微粉碎和普通粉碎在显微鉴别、天麻素及其他成分含量测定等方面的差异。方法 :同一批次天麻分别用细胞级粉碎设备和普通设备粉碎成超微粉和普通粉 ,用显微镜观察和 HPLC法测定两者的天麻素和其他成分含量。结果 :天麻超微粉不但是天麻素含量比普通粉高得多 ,而且其他成分也高得多。结论 :天麻细胞级微粉碎和普通粉碎在显微鉴别、天麻素及其他成分含量测定方面均有差异 ;证明天麻经细胞级微粉碎后的超微粉 ,可以缩短提取时间 。

OBJECTIVE:To compare micro identification, content of gastrodine and other ingredients of cellular level pulverization with those of ordinary pulverization for Gastrodia elata BL.. METHOD:The same batch of Gastrodia elata BL. was pulverized into ultra fine powder and ordinary powder by cellular level and ordinary pulverizer respectively, the characterizations of powder were indentified by micro identification and content determination of gastrodine and other ingredients were measured by HPLC. RESULTS:In addition to gastrodine, the content of other ingredients were much higher in ultra fine powder than those in ordinary powder. CONCLUSION:There was significant difference of micro identification, content of gastrodine and other ingredients between methods of cellular level and ordinary pulverization; Extracting time of active ingredients can be reduced and Extracting rate can be increased simultaneously by cellular level pulverizing.
