本文采用传统后下、分次后下、分次煎煮法三种煎煮方法对含芳香性挥发油成分药物的煎出物量、汤液色泽变化、挥发油显色反应进行实验观察比较。认为采用分次煎煮法既减少药物的受热时间,提高有效成分溶出量,又简化了操作工艺。 In this paper, three methods of decoction were used: traditional post-bottom, sub-subsequent, and sub-boiling decoctions. Experimental observation and comparison were made on the amount of decoction of aromatic volatile oils, changes in color of the decoction, and color reaction of essential oils. It is considered that the fractional decoction method not only reduces the heating time of the medicine, but also improves the dissolution amount of the active ingredient and simplifies the operating process.
