Phytochemical investigations of the fruits of Stocksia brauhica (Sapindaceae) resulted in the isolation of a new acylated flavone glycoside. Its structure of the new compound brauhenefloroside D (1) was established as 3-O-[(alpha-L-rhamnopyranosyl)oxy]-7-O-[(acetyl)-beta-D-glucopyranosyl (1 --> 4)]-[6-O-(4-hydroxy-E-cinnamoyl)-beta-D-glucopyranosyl-(1 --> 2)-alpha-L-rhamnopyranosyl)-oxy]-kaempferol. The structure elucidation of the new compound was based primarily on 1D and 2D NMR analysis, including COSY, HMBC and HMQC correlations.
对无患子科植物布氏无患子果实进行的植物化学研究，分离出一种新的酰化黄酮苷。新化合物布氏无患子苷D（1）的结构确定为3 - O - [（α - L - 鼠李糖吡喃糖基）氧基] - 7 - O - [（乙酰基） - β - D - 葡萄糖吡喃糖基（1→4）] - [6 - O - （4 - 羟基 - E - 肉桂酰基） - β - D - 葡萄糖吡喃糖基 - （1→2） - α - L - 鼠李糖吡喃糖基）氧基] - 山奈酚。新化合物的结构解析主要基于一维和二维核磁共振分析，包括COSY、HMBC和HMQC相关。
