Anthocyanins are red , purple , and blue and are wiedly distributed , particularly in flowers and fruits where they are important in attracting insects , birds , etc 花青素呈现红色、紫色或蓝色，广泛分布于花或果实中，用来吸引昆虫或者鸟类。
It shows that besides procyanidins . there are other phenolic compounds in procyanidin extract which may contribute to its great antioxidant activity 表明葡萄籽提取物强大的抗氧化活性不仅与其中所含的原花青素有关，也与其他酚类物质的存在有关。
Then , cl - i , an allele of cl , was also isolated from maize . it was thought to act as a transcriptional represser in the anthocyanin pathway 后来人们又发现了c1的等位突变基因c1 - i ，它在相应基因转录方面的调节作用与c1相反：抑制花青素的合成。
What gies the wines their higher concentration of procyanidins ? is it just the wine - making methods ? how does this differ to other areas of the world 什么原因能产生较高含量的原花青素？仅仅是红葡萄酒的酿造工艺吗？这些地区的酿造工艺与世界其它地区有什么不同？
What gives the wines their higher concentration of procyanidins ? is it just the wine - making methods ? how does this differ to other areas of the world 什么原因能产生较高含量的原花青素？仅仅是红葡萄酒的酿造工艺吗？这些地区的酿造工艺与世界其它地区有什么不同？
The expression quantity of as gene was correlated with synthesis quantity of anthocyanin . the expression of as gene was induced by light in light - dependent " tsuda " turnip As基因的表达量与花青素的合成量相关，且在光敏感型津田芜菁中， as基因的表达受光诱导。
Color may also be modified by traces of iron and other metal salts and organic substances , for example cyanin is red in roses but blue in the cornflower 此外一些微量的离子，金属盐以及其他的有机物质也可以改变其显色，例如花青素在玫瑰中显红色而在玉米花中显蓝色。
Sweetpotato storage root flesh contains the active compositions which can make the anthocyanins color fading , the pigment loss could reach more than 50 % 摘要甘薯薯肉内含有能使花青素分解退色的活性物质，在甘薯匀浆中可导致一半以上的色素损失，严重影响了色素提取效率。
The genes encoding enzymes that are needed during the anthocyanin synthesis are conservative in many higher flowering plants , especially among plants that have near relative 在许多高等开花植物中，尤其是在进化上亲缘关系比较近的物种，花青素合成各步骤所需酶的结构基因高度保守。
A mixture of catechin and epicatechin , procyanidin b4 , 4 - hydroxy - benzoic acid and ethyl gal - late were purified and identified from grape seed procyanidin extract 得到2种原花青素的单体： ( + ) -儿茶素和( - ) -表儿茶素； 1种原花青素二聚体b4 ； 2种其他酚类物质：对羟基苯甲酸及没食子酸乙酯。
