从我国蒺藜科特有属植物四合木(Tetraena mongolicaMaxim)的全株中首次得到了五种化合物。应用光谱等检测方法,对其结构进行了鉴定。分别鉴定为:十四碳酸月桂醇酯(1)、羽扇豆醇(2)、β-谷甾醇(3)、5,7,3′,4′-四羟基-3-甲氧基黄酮(4)、5,7,4′-三羟基-3,3′-二甲氧基黄酮(5)。上述成分均为首次从四合木中得到。其中5,7,3′,4′-四羟基-3-甲氧基黄酮表现出较高的抗氧化活性。 For the first time, five compounds were obtained from the whole plant of Tetraena mongolica Maxim. The spectrum and other methods were used to identify the structure. They were identified as: lauryl tetradecanoate (1), lupeol (2), β-sitosterol (3), 5,7,3′,4′-tetrahydroxy-3-methoxyflavone (4 ), 5,7,4’-trihydroxy-3,3’-dimethoxyflavone (5). All of the above ingredients were obtained from Tetraena for the first time. Among them, 5,7,3’,4’-tetrahydroxy-3-methoxyflavone showed higher antioxidant activity.
