The research advances of the anthocyanins pigment from purple sweet potato are described , including the physiological activity , the methods of extraction and purification and composition analysis 摘要概述了国内外关于紫甘薯花色苷色素的研究进展,包括其生理活性、色素提取和纯化方法、含量测定以及组分分析,为该色素的进一步开发利用提供依据。
Researches on pigmentation of flower color , types of flower pigments , biosyntheses of anthocyanins , genes of flower color , and strategies and methods of genetic engineering of flower color were described to various degrees in this paper 本文从花的成色作用和花色素种类入手,介绍了花色苷的生物合成,并从花色基因的种类和克隆、花色基因工程操作的策略和方法等角度综述了近年来观赏植物花色基因工程的研究进展。
Abstract : the diferrences in cell growth , composition and levels of anthocyanins and catechins , activity of phenylalanine ammonia - lyase and dynamics of production between anthocyanin accumulating and non - accumulating subclones of tea cultured cells were examined 文摘:从细胞生长、色素和儿茶素次生产物组成与含量、苯丙氨酸解氨酶活性以及产物合成动态分析几方面,研究比较了积累色素与不积累色素的两类茶树培养细胞系之间的差异。
Apart from imparting color to plants , anthocyanins also have an array of health - promoting benefits , as they can protect against a variety of oxidants through a various number of mechanisms . this article reviews their biological functions and the most recent analytical techniques concerning anthocyanin isolation and identification 文章根据国内外对花青素生理功能的研究报导归纳了花色苷的主要生理活性并就其成分分离和结构鉴定做了概括。
2 : the accumulation of anthocyanins : after treated by low - temperature for 3 weeks , the color of the controls " leaves turned red and could be observed from the appearance which indicated the accumulation of anthocyanins was remarkable , but there nearly has no changes on the color of transgenic plants " leaves 花青素的积累:低温处理3周后,从外观即可看出对照的叶片明显变红,花青素积累显著,而转基因苗的叶色几乎没有变化,有的微红,花青素积累极少。
