Abstract

Three prenylated rotenoids, elliptol, 12-deoxo-12alpha-methoxyelliptone and 6-methoxy-6a,12a-dehydrodeguelin were isolated from the twigs of Millettia duchesnei, together with the known compounds, 6a,12a-dehydrodeguelin, 6-hydroxy-6a,12a-dehydrodeguelin, 6-oxo-6a,12a-dehydrodeguelin, elliptone, 12a-hydroxyelliptone and eriodictyol. Their structures were elucidated on the basis of spectral data and comparison with information reported in the literature and with authentic specimens for some known compounds. The full NMR data of 6-oxo-6a,12a-dehydrodeguelin and 6-hydroxy-6a,12a-dehydrodeguelin are reported here for the first time.

摘要

从鸡血藤的嫩枝中分离出三种异戊烯基鱼藤酮类化合物，椭圆托酚、12-脱氧-12α-甲氧基椭圆酮和6-甲氧基-6a,12a-脱氢鱼藤素，以及已知化合物6a,12a-脱氢鱼藤素、6-羟基-6a,12a-脱氢鱼藤素、6-氧代-6a,12a-脱氢鱼藤素、椭圆酮、12a-羟基椭圆酮和圣草酚。根据光谱数据，并与文献报道的信息以及一些已知化合物的标准样品进行比较，阐明了它们的结构。本文首次报道了6-氧代-6a,12a-脱氢鱼藤素和6-羟基-6a,12a-脱氢鱼藤素的完整核磁共振数据。
