Two compounds, 3β-acetoxyl,2,14,22-trihydroxy,19-hydroxymethyl,9α,5β,14β-card-20(22)enolide (1) and 1,2,3,4-tetrahydro-6-hydroxy1-5-pyrimidinecarbox-aldehyde (2), were isolated from arthropods in scorpion, Buthus martensii Karsch, by medium pressure liquid chromatography with silica gel as stationary phase and RP-HPLC analysis technology. The structures were elucidated on the basis of NMR spectroscopic analysis and HR-ESI-MS determination. It was found that (1) is a novel compound and both compounds showed inhibitory activities against the Gram-positive bacteria Bacillus subtilis (minimum inhibitory concentrations = 15 μg/mL), with diameter of inhibition zone at ϕ = 6.0 mm (compound 1) and ϕ = 9.0 mm (compound 2), respectively.
两种化合物,3β-乙酰氧基,2,14,22-三羟基,19-羟甲基,9α,5β,14β-卡-20(22)烯内酯 (1) 和 1,2,3,4-四氢-6-羟基-1-嘧啶羧酸醛 (2),从节肢动物蝎子(Buthus martensii Karsch)中通过中压液相色谱用硅胶作为固定相和 RP-HPLC 分析技术分离得到。根据 NMR 光谱分析和 HR-ESI-MS 测定确定了它们的结构。发现(1)是一种新型化合物,两种化合物都显示出对革兰氏阳性菌枯草芽孢杆菌(最小抑菌浓度 = 15 μg/mL)的抑制活性,抑菌圈直径分别为 ϕ = 6.0 毫米(化合物 1)和 ϕ = 9.0 毫米(化合物 2)。
