Department of Chemistry, Zhejiang University,Hangzhou(310027)Abstract : Nine azo pigments have been synthesized by coupling 1- aminoanthraquinone with various couplers.

由1-氨基蒽醌和不同偶合基合成了九个含蒽醌基的单偶氮染料，并对其进行了元素分析、红外光谱和紫外光谱表征。

The results showed that the red pigment belonged to anthocyanidin, it was soluble in water, stable against heat treatment, light, acid and sugar concentration, tolerant to reduction, but sensitive to alkaline, oxidation and Fe(superscript 3+). The research also showed that acid medium is favorable for extraction. The pigments have more general stability in acid medium and have high ufility value.

结果表明：该色素为水溶性多酚类花色素，在不同的pH环境下显示不同的颜色；其耐热性、耐光性、耐酸、耐糖、耐还原性较好，但耐氧化性、耐碱性较差；Fe(上标 3+)对色素有破坏性；该色素的提取宜在酸性介质中进行，酸性条件下其综合稳定性较优，有较高的利用价值。

In the brewing production, Aronia berries can be processed into Aronia-brewing wine, healthy vinegar as well as lactic-acid drink. Furthermore, the natural pigment is rich in Aronia berries, such as procyanidins, anthocyanins, flavonoids and so forth. Therefore they can be used as raw materials for the production of natural pigments.

在酿造加工方面，黑果腺肋花楸可用于酿造果酒、酿制保健醋以及研制乳酸发酵型饮料；在天然色素提取方面，黑果腺肋花楸的果实富含原花青素、花色苷、类黄酮等天然色素，因此可作为天然色素生产的原材料。

Some small molecules and the synthesized azo pigments have been treated by AM1 method from a quantum chemical viewpoint.

本文对一些小分子偶氮染料和上述合成的偶氮染料首次运用AMl方法从量子化学的角度对其进行了优化计算。

In model plant Arabidopsis thaliana, also from Brassicaceae, the TRANSPARENT TESTA 12 (TT12, AtTT12) gene is seed coat-specific and encodes a vacuolar flavonoid/H+ antiporter, transporting cytoplasm-synthesized glycosylated flavan-3-ols to the vacuoles for further polymerization into seed coat pigments.

同属十字花科的模式植物拟南芥中，种皮特异表达的TT12（透明种皮12，AtTT12）基因编码一种液泡型类黄酮/H+-逆向转运蛋白，将胞浆内合成的糖苷化的黄烷-3-醇转运到液泡中，供进一步聚合形成种皮色素。
