篇名: 单因素试验结合Box-Behnken设计-响应面法优化甘草中黄酮类成分的提取工艺
TITLE:
摘要: 目的:优化甘草中黄酮类成分的提取工艺。方法:以芹糖甘草苷、甘草苷、芹糖异甘草苷、芒柄花苷4种黄酮类成分的总提取量为考察指标,以提取溶剂种类(水、乙醇)及其不同体积分数、加入量与提取时间为考察因素,在单因素试验基础上,运用Box-Behnken设计-响应面法优化甘草中黄酮类成分的提取工艺,并进行验证试验。结果:优化的提取工艺为以50%乙醇为提取溶剂,在0.200 g药材中加入50 mL,超声提取50 min。在验证试验中,芹糖甘草苷、甘草苷、芹糖异甘草苷、芒柄花苷提取量分别为10.733 0、27.784 9、3.441 9、0.429 1 mg/g(RSD均<3.0%,n=3),4种黄酮类成分平均总提取量为42.388 9 mg/g,与预测值(42.173 2 mg/g)的相对误差为0.52%(n=3)。结论:优化的提取工艺简便、快捷、稳定,可用于甘草中黄酮类成分的提取。
ABSTRACT: OBJECTIVE: To optimize the extraction technology of the flavonoids from Glycyrrhiza uralensis. METHODS: Using total contents of four flavonoids, liquiritinapioside, glycyrrhizin, isoliquiritin apioside and formononetin as indexes, types and volume fractions of extraction solvents (water, ethanol), volume of addition and extraction time as factors, based on single factor experiment, Box-Behnken design-response surface method was used to optimize the extraction technology of flavonoids from G. uralensis. Validation test was also conducted. RESULTS: The optimal extraction technology was 50 mL 50% ethanol as extraction solvent, 0.200 g G. uralensis, ultrasonic extraction for 50 min. In validation test, the extraction amounts of liquiritinapioside, glycyrrhizin, isoliquiritin apioside and formononetin were 10.733 0, 27.784 9, 3.441 9, 0.429 1 mg/g, respectively (all RSDs<3.0%, n=3). The average total extraction amount of four flavonoids was obtained was 42.388 9 mg/g, the relative error of which to predicted value (42.173 2 mg/g) was 0.52% (n=3). CONCLUSIONS: The optimized extraction technology is simple, rapid and stable, and can be used for the extraction of flavonoids from G. uralensis.
