accumulated by carrot cell cultures include some that are acylated. Addition of cinnamic and benzoic acid analogues to the culture medium resulted in the production of fourteen novel monoacylated anthocyanins. Four additional anthocyanins were prepared by partial acid hydrolysis, which selectively removed the xylose side chain from the branched trisaccharide part of the molecule. The carrot cells accommodate
摘要胡萝卜细胞培养物中积累的花青素包括一些被酰化的花青素。在培养基中加入肉桂酸和苯甲酸类似物导致产生了十四种新颖的单酰化花色苷。通过部分酸水解制备了另外四个花色苷,其从分子的支链三糖部分选择性除去木糖侧链。胡萝卜细胞可容纳多种用于酰化花青素的羧酸,并为制备带有多个酰基的花青素提供了系统。通过1 H NMR光谱和质谱,以及在pH 2和6下的UV-vis吸收光谱对化合物进行表征。
