This study evaluated methanol extracts from the leaves and branches of the Thai medicinal plant Diospyros mollis (Ebenaceae). Seven triterpenes and 22 aromatic compounds, including five new compounds, were isolated, and their structures were determined. The new compounds had the following structures: diospyrol glycoside (makluoside A, 1), 8,8′-di-O-6-β-d-apiofuranosyl-β-d-glucopyranosyl-6,6′-dimethyl-2
这项研究评估了泰国药用植物Diospyros mollis(Ebenaceae)的叶子和树枝上的甲醇提取物。分离了7种三萜和22种芳香族化合物,包括5种新化合物,并确定了它们的结构。新化合物具有以下结构:地高吡咯糖苷(makluoside A,1),8,8'-二-O -6-β- d-呋喃呋喃糖基-β- d-吡喃吡喃糖基-6,6'-二甲基-2,3 ′-联萘-1-醇-1',4'-二酮(麦角甙B,2)和3-甲基-1,8-萘二醇糖苷(麦角甙CE,3 – 5)。Makluoside B是具有3-甲基-1,8-萘二醇单元和5-羟基-7-甲基-1,4-萘醌单元的萘醌糖苷的第一个实例。评价了分离物的透明质酸酶抑制活性,发现三萜衍生物之一具有中等抑制活性。
