Results The purification effect was satisfactory when the concentration of original solution of the extract of Cacumen Platycladi was 0.20 gmL^(-1), the loading amount was 0.375 g of Cacumen Platycladi per 1 mL of wet AB-8 resin, the adsorption velocity was 1 mLmin^(-1), the eluant was 70% alcohol being 4 times as much as the resin volume, and the elution velocity was 2 mLmin^(-1). AB-8 resin could be used for 3 times repeatedly after being reproduced by 95% of ethanol and 1 moLL^(-1) of natrium hydroxydatum. The remaining rate of the total flavonoids and quercitrin was over 70% and 95% respectively, and the remaining rate of peaks 1~3 was over 90%.

Under the above conditions,the extraction yield of total flavonoids was 20.6μmol/g,rutin was 11.2μmol/g,quercitrin 5.6μmol/g,epicatechin 3.8μmol/g.

结果表明，苦荞麸皮黄酮类化合物的最佳提取工艺条件为微波加热时间15min，乙醇体积分数40%，压力400kPa。

The oxidation mechanism of synephrine was also investigated;(2) The electrochemical behavior of twelve flavonoids (quercetin, morin, fisetin, luteolin, isorhamnetin, myricetin, hyperoside, quercitrin, puerarin, farrerol, naringenin and hesperidin) was investigated. The method for the determination of flavonoids was developed by using different pulse voltammetry, and the detection limit was in the range of 10-7~10-9 mol/L. This method has been successfully employed to determine the total amount of flavonoids in pericarpium citri reticulatae and quercetin in the spiked human blood plasma samples.
