Four apigenin glycosides were isolated from the ethyl acetate extract of the leaves of Mayodendron igneum Fam.Bignoniaceae. They were identified as apigenin 7-O-glucoside; 6-methoxy apigenin-7-O-glucoside; 6-methoxy apigenin-7-O-rhamnoglucoside and 6-hydroxy apigenin-7-O-rhamnoglucoside. In addition an isoflavone glycoside was isolated, and identified as genistin 5,4'-methyl ether. Ethanol (80%) extract of Mayodendron igneum leaves exhibited significant anti-inflammatory and analgesic activities. LD(50) determination of the extract indicated the safety of the leaves of the plant.
从紫葳科火焰树的叶子乙酸乙酯提取物中分离出四种芹菜素糖苷。它们被鉴定为芹菜素7-O-葡萄糖苷、6-甲氧基芹菜素-7-O-葡萄糖苷、6-甲氧基芹菜素-7-O-鼠李糖葡萄糖苷和6-羟基芹菜素-7-O-鼠李糖葡萄糖苷。此外，还分离出一种异黄酮糖苷，并鉴定为染料木苷5,4'-甲醚。火焰树叶子的乙醇（80%）提取物表现出显著的抗炎和镇痛活性。提取物的半数致死量（LD50）测定表明该植物叶子的安全性。
