国标方法分析了日本花柏心材外缘的基本化学组成,并利用气质联用仪对其心材外缘的二氯甲烷提取物化学组分进行了分析,根据计算机数据库鉴定出14种化合物。二氯甲烷提取物中主要化学组分是萜烯类和萘衍生物。在14种化合物中,含量最高的组分是7-甲基-4-亚甲基-1-(1-异丙基)-(1.α,4a.α,8a.α)-1,2,3,4,4a,5,6,8a-八氢化萘(35.235%)。用黑曲霉对二氯甲烷提取物进行抑菌性能测试,结果表明该提取物对黑曲霉没有抑菌能力。图4表2参29。 The chemical composition of methylene chloride extracts from the outer edge of heartwood was analyzed by GC-MS, and 14 compounds were identified based on the computer database. The main chemical components in dichloromethane extract are terpenes and naphthalene derivatives. Among the 14 compounds, the highest content of the components was 7-methyl-4-methylene-1- (1-isopropyl) - (1.α, 4a.α, 8a.α) , 3,4,4a, 5,6,8a-octahydronaphthalene (35.235%). Aspergillus niger dichloromethane extracts were tested for antibacterial activity, the results show that the extract has no antibacterial activity against Aspergillus niger.
