    Extract RE was obtained from the roots of Althaea officinalis in a yield of 8.1%, related to the dried plant material, by extraction with MeOH–H2O (1:1), followed by precipitation with EtOH to remove high molecular weight constituents. Phytochemical investigation of RE revealed the presence of N-phenylpropenoyl-l-amino acid amides 1–5, 8% glycine betaine 6, about 9% total amino acids with proline as

Apart from flavonoid 8-hydroxylase activity, the presence of all enzymes involved in the formation of flavonoid 7-O-glucosides in C. segetum was demonstrated. The pathway leading to 8-hydroxyflavonoids in C. segetum has been derived from enzyme activities and
    黄色黄酮醇有助于科植物的花色素沉着。与普通黄酮醇相比,它们除了基本的 5,7-羟基化模式外,在芳香族 A 环的 6 位和/或 8 位还显示出额外的羟基。首次用来自花花瓣的酶制剂证明了一种在黄酮醇和黄酮的 8 位引入羟基的酶。黄烷酮、二黄酮醇和糖基化黄酮醇和黄酮不被接受为底物。该酶位于微粒体部分,并使用 NADPH 和 FAD 作为辅助因子。用一氧化碳/蓝光和对细胞色素 P450 还原酶特异的抗体进行的实验没有表明经典的细胞色素 P450 依赖性单加酶参与反应。因此,类黄酮 8-羟化酶代表了类黄酮途径中的一种新型羟化酶。除了黄酮类 8-羟化酶活性外,还证明了在 C. segetum 中存在参与黄酮类 7-O-葡萄糖苷形成的所有酶。导致 C. segetum 中 8-羟基黄酮类化合物的途径源自观察到的酶活性和底物特异性。

    Herein, we report the use of the Suzuki–Miyaura cross-coupling reaction for the preparation of a library of synthetic derivatives of flavonoids for biological activity assays. We have investigated the reactivity of halogenated flavonoids with aryl boronates and with boronyl flavonoids. This reaction was used to prepare new synthetic derivatives of flavonoids substituted at C-8 with aryl, heteroaryl
