Tagetes patula L. (marigold) is a valuable source of biologically active compounds, including flavonoids. A quantitative determination method for total flavonoids in T. patula flowers using differential spectrophotometry at analytical wavelength 428 nm and a reference standard of patulitrin (3,5,7,3′,4′-pentahydroxy-6-methoxyflavone 7-O-β-D-glucopyranoside) was developed during the present work. The error of a single determination of total flavonoids in T. patula flowers was ± 3.86% with confidence probability 95%. The content of total flavonoids in T. patula flowers varied from 6.12 ± 0.07% to 8.30 ± 0.12%.

万寿菊万寿菊花中总黄酮的定量测定

万寿菊（万寿菊）是生物活性化合物（包括类黄酮）的重要来源。在总类黄酮的定量测定方法孔雀草使用差分光光度法在分析波长428 nm和patulitrin的参考标准（3,5,7,3'花，4'-五羟基-6- methoxyflavone -7- ö -β-在当前工作中开发了D-吡喃葡萄糖苷。pat蒲花中总黄酮的单次测定误差为±3.86％，置信概率为95％。蒲花中总黄酮含量从6.12±0.07％到8.30±0.12％。
