A reversed-phase high-performance liquid chromatographic method is described for the simultaneous determination of seven flavonoids in Potentilla multifida: hyperin, quercetin-3-O-beta-D-glucopyranoside, luteolin-7-O-beta-D-glucuronide, apigenin-7-O-beta-D-glucuronide, quercetin, tribuloside, and apigenin. The method involves the use of a Hypersil octadecylsilyl silica (ODS) analytical column (125A, 5 microm, 4.6 x 250 mm) at 25 degrees C with the mixture of acetonitrile and aqueous H(3)PO(4) as the mobile phase and detection at 254 nm. The recovery of the method is 95.4-104.8%, and linearity (r > 0.9998) is obtained for all the flavonoids. The results indicate that the flavonoid content of P. multifida varied significantly from locality to locality.
描述了一种反相高效液相色谱法,用于同时测定多裂委陵菜中的七种黄酮类化合物:金丝桃苷、槲皮素 - 3 - O - β - D - 吡喃葡萄糖苷、木犀草素 - 7 - O - β - D - 葡萄糖醛酸苷、芹菜素 - 7 - O - β - D - 葡萄糖醛酸苷、槲皮素、刺蒺藜苷和芹菜素。该方法采用Hypersil十八烷基硅烷硅胶(ODS)分析柱(125Å,5μm,4.6×250mm),在25℃下,以乙腈和磷酸水溶液的混合物为流动相,并在254nm处进行检测。该方法的回收率为95.4 - 104.8%,所有黄酮类化合物均获得线性关系(r > 0.9998)。结果表明,多裂委陵菜中黄酮类化合物的含量因产地不同而有显著差异。
