A phytochemical investigation of the leaf exudate of Aloe marlothii has resulted in the isolation of a new chromone (7-O-methylaloeresin A) and a new anthrone (5-hydroxyaloin A 6'-O-acetate). Furthermore 7-O-methylaloesin was isolated as a natural product for the first time from the leaf exudate of Aloe rupestris. The structure elucidation of these compounds was based on spectral data including 2D NMR. The chemotaxonomic value of 7-O-methylaloesin in Aloe series Asperifoliae and section Pachydendron is discussed.
对多叶芦荟叶渗出物进行的植物化学研究，已分离出一种新的色酮（7 - O - 甲基芦荟树脂A）和一种新的蒽酮（5 - 羟基芦荟苷A 6'- O - 乙酸酯）。此外，7 - O - 甲基芦荟素首次作为天然产物从岩生芦荟的叶渗出物中分离出来。这些化合物的结构解析基于包括二维核磁共振在内的光谱数据。讨论了7 - O - 甲基芦荟素在芦荟属阔叶芦荟系和厚叶芦荟组中的化学分类学价值。
