摘要
目的测定单味根及根茎类中药饮片在常温下的吸水系数,对煎药机在中药煎煮过程中的加水量提供依据。方法通过对222味根及根茎类中药饮片的吸水系数进行研究,将模拟药方分别按煎药机厂家推荐公式和吸水系数计算加水量煎煮,两者得到的出液量分别与需液量比较。结果不同质地的根及根茎类中药饮片吸水系数差异较大,按煎药机厂家推荐公式加水所得的出液量与需液量相差较大且无规律可循,而按吸水系数加水所得的出液量与需液量误差较小且有规律可循。结论实验测定中药饮片的吸水系数可指导煎药工在煎药时的加水量。
Objective To determine the water absorption coefficient of single-flavor root and rhizome Chinese herbal medicine pieces at room temperature,and guide the water addition in the decoction process of decocting machine of Chinese herbal.Methods The water absorption coefficient of 222-flavor root and rhizome Chinese herbal medicine pieces were studied,the simulated prescriptions were decocted according to the recommended formula of the decocting machine manufacturer and the water absorption coefficient,and the amount of liquid were obtained by the two methods which were compared with the amount of liquid required.Results The water absorption coefficients of roots and rhizomes with different textures were quite different.The amount of liquid obtained according to the manufacturer′s recommended formula was quite different from the amount of liquid required and there was no rule to follow.The error of the amount of liquid obtained according to the water absorption coefficient and the amount of liquid required was small and regular.Conclusion The experimental determination of the water absorption coefficient of traditional Chinese medicine decoction pieces could guide the amount of water added to the decoction machine.
