%X 对赫章半夏总生物碱(Total alkaloids from Pinellas ternata)的提取工艺进行研究，通过加入适量氨水、乙酸乙酯辅以超声波提取，以盐酸麻黄碱(Ephedrine hydrochloride)为标准品对提取到的总生物碱含量进行测定。通过单因素试验，得出提取的最佳条件为：粒径大小80目、氨水浓度25%、浸提溶剂量18倍和浸提时间3 h，该条件下生物碱提取率为10.65 mg/g。<br />
The extraction technology of total alkaloids from Pinellas ternata was studied. By adding appropriate amount of ammonia, ethyl acetate and ultrasonic extraction, the total alkaloid content extracted was determined with ephedrine hydrochloride as the standard. Through single factor test, the optimal extraction conditions were as follows: particle size of 80 mesh, ammonia concentration of 25%, extraction solvent of 18 times and extraction time of 3 h. Under these conditions, the extraction rate of alkaloids was 10.65 mg/g.
