摘要
采用正交设计法测定各样品的氯仿提取液和水煎浓中总生物碱含量。其最佳方案有两种:以煎剂入药时,可将鲜元胡个用食醋烫至无白心;若提取总生物碱浸膏制备中成药时,可将鲜元胡个用含1/2食醋的醋水液烫至微沸。
The Total alkaloid contents of chloroform extracts and aqueous decoctions of different vinegar-processed samples of fresh Rhizoma Corydalis were determined and compared using orthogonal experimental design. Two optimum schemes suggested by the results are 1. If aqueous decoction is wanted, the fresh tuber Corydalis should be scalded by hot edible vinegar till the liquid has permeated to its center; 2. If total alkaloid extract is required for making Chinese traditional patent medicine, the fresh Rhizoma should be slightly scalded with edible vinegar which has been diluted with an equal volume of water.
