摘要
目的:确定郁金浸润切片的最佳工艺参数。方法:测定温郁金Curcumawenyujin和桂郁金Ckwangsiensis水浸泡前后的药材质量变化、挥发油类成分变化、甲醇和氯仿提取物质量变化和莪术烯醇的含量变化,以确定炮制的质量控制指标;并研究了不同大小的温郁金的最短加压浸制时间和闷润时间及最佳干燥温度。结果和结论:①水浸泡过程郁金药材质量减少,挥发油类成分含量有变化,但甲醇和氯仿提取物量和有效成分莪术烯醇的含量变化不明显,因而确定以尽可能短的浸泡时间为炮制控制指标。②加压浸泡能明显缩短药材浸泡时间,加压浸泡时间与药材断面的短径相关。③郁金加压浸泡工艺为:浸泡-0.095MPa05h,014MPa10～16h,闷润36～48h,切片,室温晾干或不高于40℃烘干。
Objective: To determine the best processing technology parameters. Method: The changes of the weights, volatile constituents, total extract quantities by MeOH or CHCl 3 and curcumenol contents of the roots of Curcuma wenyujin and C. kwangsiensis roots before and after water soaking were determined, so as to determine the quality control index for the process of preparing Yujin slices. The shortest soaking and moistening time and the appropriate drying temperature were studied. Result and Conclusion: (1)The weight was decreased and the quantities of volatile constituents were changed during water soaking process. But the total extracts quantities and the curcumenol contents didn't change obviously. So the quality control index was decided as soaking as short as possible. (2) The soaking time could be decreased by using high pressure. The soaking time was related with the short diameter of the cross section of the root. (3) The soaking under pressure technology is that soaking on -0.095 MPa for 0.5 h, then on 0.14 MPa for 10-16 h, and moistening for 36-48 h, cutting drying in room temperature or less than 40 ℃.
