目的：优选槐米防晒成分芦丁的最佳提取工艺。方法采用紫外分光光度法检测槐米提取液在波长200~400 nm各区间的平均吸收率，采用高效液相色谱法测定其主要成分芦丁含量。分别以槐米提取液紫外吸收率、芦丁含量为指标，对超声波提取工艺进行单因素考察，并采用L9(34)正交试验优选槐米芦丁的提取工艺。结果槐米提取液在UVA、UVB、UVC波段内对紫外线均有较强的吸收作用。槐米提取液的最佳提取工艺：乙醇浓度为70%，料液比为1：30，超声时间为30 min，超声温度为65℃。结论槐米提取液在紫外各区间均有较强吸光能力，具有很好的广谱防晒能力。超声波提取法具有时间短、提取率高等优点，可用于槐米防晒成分芦丁的提取。

Objective To optimize the extraction of Flos Sophora. Methods The samples were scanned from 200 to 400 nm by ultraviolet spectrophotometry, then the average ulrtaviolet absorption was calculated in UVC, UVB and UVA. The quantity of rutin was determined by HPLC. With ultraviolet absorption, rutin content and extraction rate as indexes, the single factor tests and orthogonal experimental design tests L9 (34) were applied to investigate the influence of each factor during ultrasonic extraction. Results The extraction of Flos Sophora had strong UV absorption effect in the UVA, UVB, UVC range. The optimal conditions for extracting were as follows: 70% ethanol concentration, 1:30 solid-liquid ration, 30 min and 65℃ ultrasound extraction. Conclusion The extraction of Flos Sophora has good ability of ultraviolet ab-sorption and broad-spectrum sun protection. Ultrasonic wave extraction has high extraction yield and requires short time which can be used to extrat sunscreen formulation from Flos Sophora.
