From the methylene chloride extract of Ehretia ovalifolia leaves, a new flavone derivative named ovalifolin [3-(3-methyl-1-butenyl)-6-methoxy-5,7,4'-trihydroxy flavone] has been isolated and identified together with the known flavone aglycones apigenin, luteolin and the highly methoxylated flavanol araneosol. The structures of these metabolites have been established on the basis of chemical, chromatographic and spectral methods.
从椭圆叶厚壳树叶片的二氯甲烷提取物中，分离并鉴定出一种名为椭圆叶黄酮醇[3-(3-甲基-1-丁烯基)-6-甲氧基-5,7,4'-三羟基黄酮]的新黄酮衍生物，以及已知的黄酮苷元芹菜素、木犀草素和高度甲氧基化的黄烷醇蛛丝菌素。这些代谢产物的结构已通过化学、色谱和光谱方法确定。
