From leaves of Rhus alata, one new benzofuranic acid named [(2E)-3-(4-hydroxy-5,7-dimethyl- benzo[3,4-b] furan-6-yloxy)-prop-2-enoic acid has been isolated together with eight known compounds: dimethyl ester of terephthalic acid, beta-amyrin, friedelin, lupeol, beta-sitosterol, oleanolic acid, taraxerone and ethyl gallate. Structural elucidations were done on the basis of chemical and physical data (IR, UV, 1H-NMR, 13C-NMR and MS spectra).
从盐肤木的叶子中,分离出一种新的苯并呋喃酸,即[(2E)-3-(4-羟基-5,7-二甲基苯并[3,4-b]呋喃-6-基氧基)-2-烯丙酸,同时还分离出8种已知化合物:对苯二甲酸二甲酯、β-香树脂醇、软脂醇、羽扇豆醇、β-谷甾醇、齐墩果酸、蒲公英赛酮和没食子酸乙酯。通过化学和物理数据(红外光谱、紫外光谱、1H-核磁共振谱、13C-核磁共振谱和质谱)对其结构进行了鉴定。
