The objective of this study is to isolate and clone the genes of flavonoid biosynthesis in Brassica juncea.

分离和克隆芥菜型油菜类黄酮合成相关基因。

UV-B-induced damage in such leaves could be reduced with 0.5 mmol.L-1 NaHSO3 treatment; brown spots on the leaf surface were reduced in number, the degree of leaf wilt was reduced, degradation of chlorophyll and carotinoid was reduced and flavonoid level was increased. With the NaHSO3 treatment, the content of H2O2 in leaves of Phaseolus vulgaris under enhanc ed UV-B radiation was significantly lower than in controls, and the activities of antioxidant enzymes were higher with treatment than in controls.

结果表明：与未处理对照相比较，用0.5 mmol.L-1 NaHSO3处理的离体红芸豆叶片表面褐色斑减少、边缘蜷曲及萎蔫程度降低；且能延缓叶片中叶绿素和类胡萝卜素含量的降低；使类黄酮含量升高；叶片中过氧化物酶和抗坏血酸过氧化物酶活性升高，过氧化氢(H2O2)含量降低。

This is because a lot depends on the type of cocoa beans used and how they have been processed.

这是因为类黄酮的含量很多取决于使用何种类型的可可豆和对可可豆加工处理的方法。

Corder and his associates maintain that traditional wine-making methods and use of the flaonoid-rich grape Tannat commonly grown in southwest France result in high leels of oligomeric procyanidins in the local wine.

Corder及其同事认为传统造酒工艺以及使用在法国西南部广泛种植的富含类黄酮的葡萄使得当地红酒前氰定低聚物水平较高。

In order to explore the mechanism of the resistance to cucumber damping-off induced by plant growth-promoting rhizobacteria CH1, the physiological and biochemical method was employed to study the changes in activities of Phenylalanine ammonia-lyase, Polyphenol oxidase and contents of ferulic acid, chlorogenic acid, lignin, phenolic compound and flavonoid of phenolic metabolism in cucumber roots pretreated with plant growth-promoting rhizobacteria CH1 and infected by Pythium aphanidermatum.

为研究植物生长促生细菌CH1诱导黄瓜对猝倒病的抗性的作用机制，采用生理生化的方法，测定了黄瓜根部酚类物质代谢中苯丙氨酸解氨酶、多酚氧化酶活性动态及阿魏酸、绿原酸、木质素、总酚、类黄酮含量变化。

Flavonoids can act as antioxidants, free radical scavengers, and chelators of divalent cations and have a wide range of biological effects .

类黄酮是一组化学结构和性质上不同的多酚化合物，具有抗氧化、自由基清除和二价阳离子螯合作用，具有广泛的生物学功能。

Carotenoids in carrots and tomatoes, isothiocyanates in broccoli and cabbage, and flavonoids in soy, cocoa and red wine are just a few examples.

例如，胡萝卜和番茄中的类胡萝卜素、椰菜和卷心菜中的硫氰酸盐、以及大豆、可可和红酒中的类黄酮。

Anthocyanins are plant unique phenolic compounds derived from flavonoid biosynthetic pathway. The red cyanidins, orange pelargonidin, and purple-blue delphinidin are three major anthocyanins, which are reported to have anti-oxidative activity on lipid and scavenge activity on removing free radical.

花青素是植物所特有的多酚类化合物，也是类黄酮代谢路径所衍生的化合物，植物主要的花青素有紫红色的矢车菊素、橘红色的天竺葵素及蓝紫色的飞燕草素等三种，均为抗氧化物，可抑制脂质过氧化，并具有清除自由基的能力。

The cultivar 'Dongzao' of Chinese jujube was used to study the types and content variations of flavonoids in fruit peel during colorling progress.

以'冬枣'为试材，对果皮着色过程中类黄酮类物质的成分及含量变化进行了研究。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
