| 中文摘要:目的 测定单味全草类中药饮片在常温下的吸水系数，以对采用煎药机煎煮中药的加水量提供依据。方法 通过对107味全草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计算的加水量和按吸水系数计算的加水量进行煎煮，把两者得到的出液量与需液量进行比较。结果 不同质地的全草类中药饮片之间的吸水系数差异较大，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对指导煎药工用煎药机煎药所需加水量具有实际指导意义。 |

| Abstract:Objective To determine the water absorption coefficient of each individual whole grass Chinese herbal medicine pieces at room temperature,and to guide the water addition in the decoction process of Chinese herbal by the decocting machine.Methods Through the study of the water absorption coefficient of 107 kinds of Chinese herbal medicine pieces,the simulated prescriptions were decocted according to the recommended formula provided by the decocting machine manufacturer or according to and the water absorption coefficient.The amount of liquid obtained by the two methods was compared with the amount of liquid required.Results The water absorption coefficients of the whole grass Chinese herbal medicine pieces,with different characteristic 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.Plus,there was no specific rules to follow.However,the error between the amount of liquid obtained according to the water absorption coefficient and the amount of liquid required was small and there was a regular pattern to follow.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. |
