摘要
以夹竹桃为原料,先通过叶的生物碱提取实验确定提取生物碱的浸提液为0.025mol/L稀硫酸,最佳提取时间5h,最佳提取温度40℃。然后按上述条件分别测定茎、叶、皮中生物碱的含量,得出夹竹桃各部位生物碱的含量为皮>叶>茎。
The extraction conditions are confirmed through the extraction of leaf of Nerium indicum Mill. The optimal conditons are： the liquor of extraction is the sparse sulfuric acid （0. 025 mol/L）, the time of extraction is 5 h, the temperature of extraction is 40 ℃. According to the experimental conditions above, the content of alkaloid in bark is maximum, the content of alkaloid in turn is ： bark 〉 leaf 〉 stalk.
