柑橘类黄酮成分的同步HPLC检测

目的建立检测柑橘类黄酮(柚皮苷、橙皮苷、新橙皮苷、橙黄酮、川陈皮素)的中药材质量控制用快速HPLC方法.方法用仅含甲醇和水的无盐流动相梯度洗脱,Kromasil反相分析柱(100-5C18-250A,4.6 mm×250 mm,5 μm),结合二级阵列管紫外扫描做峰识别.结果对于要检测的5种柑橘类黄酮均得到满意的分辨率和线性范围,其加样回收率95%～102%;重现性RSD 1.88%～2.93%分析了6种酸橙类柑橘中药材黄酮含量.结论建立了多成分柑橘类黄酮快速HPLC检测方法并可用于LC-MS.

Citrus fiavonoids simultaneous HPLC analysis

AIM: To develop a rapid HPLC method for quality control of traditional Chinese medicinal ingredients consisted of citrus flavonoids, naringin, hesperidin, neohesperidin, sinensetin and nobiletin. METHODS:Gradient elution with non-salt mobile phase ( methanol and water only) HPLC method on a Kromasil column ( 100-5C18-250A, 4.6 mm ×250 mm, 5 μm, C18 reverse phase) with peaks identification through DAD full UV wavelength scan. UV 284 nm and 332 nm profiles were observed. RESULTS: Satisfactory resolution, linearity, 95%～ 102% of recovery and 1.88 ～ 2.93% of repeatability were obtained for those five citrus flavonoids. Content of 6 Citrus aurantium L. based TCM ingredients were analyzed and identified. CONCLUSION: Rapid HPLC test method on citrus flavonoids was developed and can be in LC-MS identification.
