Chemical investigation of the leaves of Tephrosia apollinea has yielded a new flavanone named (+)-apollineanin, together with two known flavones: (-)-semiglabrin and (-)-semiglabrinol. The structure of the new compound was determined on the basis of mass, 1D and 2D NMR spectroscopies including NOE difference spectroscopy. The absolute stereochemistry of (+)-apollineanin was determined by Mosher ester methodology and from CD data.
对紫穗槐叶进行化学研究,得到了一种名为(+)-紫穗槐宁的新黄烷酮,以及两种已知黄酮:(-)-半光荚豆素和(-)-半光荚豆醇。通过质谱、一维和二维核磁共振光谱(包括NOE差光谱)确定了新化合物的结构。通过莫舍尔酯法和圆二色光谱数据确定了(+)-紫穗槐宁的绝对立体化学结构。
