Protoplumericin, 13-O-(β-D-glucopyranosyl-p-coumaroyl)-plumieride (IV), was isolated from the polar fraction of the MeOH percolate of Allamanda neriifolia HOOK by means of several column chromatographies and droplet counter current chromatography. Enzymatic and alkaline transformations of IV into plumericin (I) and plumieride (III), respectively, were carried out.
通过多次柱色谱和液滴逆流色谱,从钩藤(Allamanda neriifolia HOOK)甲醇渗滤液的极性部分中分离出原普鲁梅利辛(Protoplumericin,13-O-(β-D-吡喃葡萄糖基-对香豆酰)-普鲁梅利德(IV))。分别将IV酶促转化成普鲁梅利辛(I)和普鲁梅利德(III),并进行了碱性转化。
