摘要: 采用高效液相色谱(HPLC)法检测了通过低温微波辐射辅助处理后橘皮中类柠檬苦素的含量,并对提取分离后所得的类柠檬苦素以果蝇为实验对象进行了驱蝇效应探讨。提取实验应用正交试验设计法,考察提取溶剂、溶液pH值、提取温度、提取时间、料液比五个因素对橘皮中类柠檬苦素提取率的影响,采用正交实验设计表L16(45)对橘皮中类柠檬苦素的提取工艺进行了优化。结果表明,最优提取工艺为:无水乙醇作为提取剂、溶液pH=5、提取温度50 ℃、提取时间120 min、料液比1:12。在最优工艺条件下,橘皮中类柠檬苦素提取量为0.876 mg/g。在驱蝇效应实验中,通过不同浓度的类柠檬苦素对果蝇驱除效应的比较,发现时间和浓度对果蝇均有影响,但浓度效应大于时间效应,喷洒1.152 mg/mL浓度的类柠檬苦素溶液可以在12h内将果蝇全部杀死。

Abstract: In this study,the limonoids was extracted from orange peel by low-temperature microwave radiation and solvent reflux extraction.The content of limonoids was determined by high performance liquid chromatography (HPLC).The orthogonal experiment design was used to optimize the extraction conditions.In addition,the anthelmintic effect of the extract was tested on drosophila.The results showed that the optimal extraction conditions were:using ethanol as extraction solvent,pH of 5,extraction temperature of 50 ℃,extraction time of 120 min,material/solvent ratio of 1:12.Under the optimal conditions,the extraction yield of limonoids was 0.876 mg/g.Different concentrations of limonoids extract all showed anthelmintic effects on drosophila in time and concentration dependent manner.The effect of sample concentration was higher than the effect of time.When the concentration of extract reached 1.152 mg/mL,drosophila was all killed in 12 hours.

Key words: high performance liquid chromatography, orange peel, limonoids, extraction process, anthelmintic effect
