they have a common biosynthetic origin in which cinnamyl pyrophosphate (or its equivalent) is the postulated precursor of the neoflavanoids. It is suggested that the natural dalbergiones, dalbergins and benzophenones are inter-related as transformation products of neoflavanoids.
Machaerium scleroxylon心材和边材产生了新的天然产物,O-乙酰油醇醛(I),R-3,4-二甲氧基dalbergione(IV),其相应的喹诺醇(Va)以及二苯甲酮衍生物scleroin(X)如已知的达巴丹(IIa)和O-甲基达巴丹(IIb)。黄烷酮和黄柏素的共存表明它们具有共同的生物合成来源,其中肉桂酸焦磷酸酯(或其等价物)是新黄酮的假定前体。有人提出,天然的黄烷酮,黄柏素和二苯甲酮是相互关联的新黄酮类化合物的转化产物。
