在鼠尾草（Salvia uliginosa）的蓝色花瓣中发现了一种金属花青素（cyanosalvianin）。cyananosalvianin由3-O-（6- o -对香豆醇基葡萄糖吡喃基）-5- o -（4- o -乙酰基-6- o -丙二醇基葡萄糖吡喃基）飞燕草苷、7,4'-二- o -葡萄糖吡喃甲素和镁离子组成。我们将这三种成分混合在一起，重现了与花瓣相同的蓝色。ESI-MS测定其分子量为9014，表明其组成为6个花青素分子、6个黄酮分子和2个镁离子。用CD和2D-NMR分析了氰丹参素中有机成分的特殊排列。结果表明，cyanansalvianin与commelin具有相似的结构，commelin是一种从山茱萸（Cornmelina communis）中分离的中间体花青素。(c) 2008 Elsevier Ltd.版权所有。
A metalloanthocyanin, cyanosalvianin, was found in blue petals of Salvia uliginosa. Cyanosalvianin consisted of 3-O-(6-O-p-coumaroylglucopyranosyl)-5-O-(4-O-acetyl-6-O-malonylglucopyranosyl) delphinidin, 7,4'-di-O-glucopyranosylapigeiiin and magnesium ion. We reproduced the same blue color as the petals by mixing the three components together. An ESI-MS measurement gave a molecular weight of 9014 indicating the composition of cyanosalvianin to be six molecules of the anthocyanin component, six molecules of the flavone component and two magnesium ions. The special arrangement of the organic components in cyanosalvianin was analyzed by CD and 2D-NMR spectroscopy. It was clarified that cyanosalvianin has a similar structure to that of commelinin, a nietalloanthocyanin isolated from blue dayflower, Cornmelina communis. (c) 2008 Elsevier Ltd. All rights reserved.
