比较藏药中不同炮制方法对铁屑炮制品中Fe~(2+)含量的影响,探讨其较显著的影响因素。在收集到的4种工艺中,按照《中华本草·藏药卷》记载工艺所制得的铁屑炮制品Fe~(2+)含量最高;炮制过程中影响铁屑炮制品中Fe~(2+)含量的因素,依次是铁屑煎煮时间>诃子粉加入量>铁屑粒度;密封阶段影响铁屑炮制品中Fe~(2+)含量的主要因素是温度。而不同炮制方法所制得的铁屑炮制品中Fe~(2+)含量有显著差异;对炮制和密封阶段关键因素的控制,能显著影响炮制品中Fe~(2+)含量。
The effects of different processing methods on the Fe ~ (2+) content in processed products of iron filings were compared, and the more significant influencing factors were discussed. Among the four collected technologies, the content of Fe 2+ in the fermented products prepared according to the record of “Chinese Materia Medica Tibetan Medicine Volume” was the highest; the content of Fe 2+ in the fermented products +) Content, followed by iron decoction time> myrobalan powder addition> iron scrap particle size; sealing stage The main factor that affects the content of Fe ~ (2+) in the iron filings is the temperature. However, the content of Fe2 + in the fermented products prepared by different processing methods was significantly different. The control of the key factors during processing and sealing could significantly affect the content of Fe2 + in processed products.
