摘要 建立HPLC法同时测定不同产地川佛手中木犀草素、6,7-二甲氧基香豆素、莨菪亭、5,7-二甲氧基香豆素、7-羟基香豆素、橙皮苷、槲皮素、阿魏酸8种成分含量的方法。采用Thermo BDS HYPERSIL C18(250 mm×4.6 mm,5μm)色谱柱,甲醇-0.2%冰醋酸水溶液进行梯度洗脱,流速1 mL/min,柱温30℃,检测波长322 nm。在该色谱条件下,川佛手中8种成分分离良好,平均加样回收率为91.22%~96.52%,RSD<5.0%。不同产地的川佛手中8种成分含量存在差异,部分成分之间存在相关性,样品聚为3类。产于四川省宜宾市长宁县老翁镇的川佛手质量最优。该方法可为川佛手的资源开发利用、质量控制以及安全评价提供参考依据。 To establish a HPLC method for the simultaneous determination of Luteolin,6,7-dimethoxycoumarin,Scopoletin,5,7-dimethoxy coumarin,7-hydroxy coumarin,Hesperidin,Quercetin,Ferulic acid in Fructus ctris sarcodactylis from different regions.Thermo BDS HYPERSIL C18(250 mm×4.6 mm,5μm)column was used,with methanol-0.2% glacial acetic acid as the mobile phases in gradient elution mode.The column temperature was 30℃,with flow rate 1.0 mL/min.The detection wavelength was set at 322 nm.The eight kinds of active ingredients components in Fructus ctris sarcodactylis were separated well in the chromatographic conditions.The average recoveries were between 91.22%-96.52%,RSD<5.0%.There were differences in the contents of eight components in 48 species.There was a correlation between some active ingredients.The samples of medicinal materials from 48 producing area could be divided into 3 categories.The quality of Fructus ctris sarcodactylis from Lao weng town,changning county,yibin city,sichuan province was the best.This study on active ingredients in Fructus ctris sarcodactylis can be used to provide guidance for the quality control and safety evaluation.
