本文对六味地黄汤不同工艺制备的汤剂和拆方配伍进行了化学成分的初步研究,以薄层扫描法定性比较。发现复方汤剂中的化学成分不等于单味药化学成分之和,在全方和不同配伍中均有新峰出现。在水提取液中化学成分比乙醇提取液中多。初步研究结果提示,对中药方剂改变剂型和开发新制剂时,应充分注意化学成分的变化,以保证新制剂的疗效。 In this paper, the chemical composition of the decoction prepared by different technology of Liuwei Dihuang Decoction and the compatibility of disassembled prescriptions were studied. It was found that the chemical composition in the compound decoction was not equal to the sum of the chemical components of the individual herbs. New peaks appeared in all the combinations and in different combinations. There are more chemical components in the aqueous extract than in the ethanol extract. The preliminary findings suggest that when changing prescriptions and developing new preparations, Chinese herbal medicines should pay full attention to changes in chemical composition to ensure the efficacy of new preparations.
