以桩柑核为原料，研究水溶助剂法提取桩柑核中柠檬苦素类物质的最佳工艺参数。结果表明：以水杨酸钠为提取溶剂，提取剂浓度为2．5mol／I。，提取时间6h，浸提温度40℃，料液比1：20（m：V）条件下，柠檬苦素类物质的最佳提取率为4．21％，四因素对柠檬苦素类物质提取率的影响次序为料液比〉浓度〉时间〉温度。

The extraction conditions of Limonoids in Ponkan pit were studied. Taking Ponkan pit powder as the raw material, with single factor experiment and orthogonal test, the optimization extracting processing parameters were studied on Limonoids in Ponkan-pit by hydrotropic solvent means. The optimal extracant concentration, ex- traction time, temperature, ratio of material to extractant were 2.5 mol/L sodium salicylate, 6 h, 40 ℃, 1 ： 20（m ： V）, respective ly. The optimum rate of extraction on Limonoids was 4. 214 % under the conditions. In the...
