白芷饮片产地加工方法探索

目的:探讨建立白芷饮片的产地加工炮制方法。方法:测定不同干燥状态下白芷药用部位的含水量,并进行饮片的炮制加工,以《中国药典》规定的方法对不同方法炮制加工的白芷饮片进行浸出物及有效成分欧前胡素和异欧前胡素的含量比较。结果:白芷药用部位含水量在29%～21%时,炮制加工的饮片中有效成分及浸出物的含量与传统饮片较接近,可作为饮片产地加工工艺参数。结论:产地加工方法不仅解决了白芷饮片炮制加工过程中软化时间过长的问题,而且节约了生产成本,保证了饮片质量的稳定,是一种适于饮片生产企业规模化、规范化生产的新型炮制方法。

Research on Habitat Processing Method of Angelica dahurica

Objective: To discuss and establish the habitat processing method of Angelica dahurica. Method: The water content of medicinal parts of A. dahurica were determined under the different dry conditions,then,evaluate the quantities in different pieces by comparing the contents of ethanol soluble extraction,imperatorin and isoimperatorin accordance with the "Chinese Pharmacopoeia". Result: It is more convenient for processing when the water content of medicinal parts were at 29%-21%.At the same times,the contents of extraction and active ingredients were close to traditional pieces. Conclusion: Habitat processing method not only shorten the soften time in processing,but also save the cost of production to ensure quality of pieces.It is a new processing method for modern scale and standardized production of Chinese herbal pieces.
