目的:探讨苍术煎药最佳方法。方法:本实验通过拟定三种煎煮方法:A不浸泡后下、B浸泡煎煮、C浸泡后下,以及五个煎煮时间段:5min、10min、15min、20min、25min,对苍术药材煎煮,并进行平行实验,所得汤液用挥发油测定器,测定汤液中所含挥发油的含量及浸出物的含量。计算挥发油提取率和浸出物得率。结果:挥发油提取率以浸泡后下10min为最高,浸膏的出膏率则随着煎煮时间的延长而呈现增加趋势。
Objective: To explore the best method of decocting herbal medicine. Methods: This experiment developed three decoction methods: A not soaked, B soaked, C soaked, and five decoctions: 5min, 10min, 15min, 20min, and 25min. Boil, and conduct parallel experiments, the resulting soup using a volatile oil measuring device to determine the content of volatile oil and leachate content in the soup. The volatile oil extraction rate and the leachate yield were calculated. Results: The extraction rate of volatile oil was the highest after soaking for 10 min, and the extracting rate of the extract showed an increasing trend with the prolonged boiling time.
