Nematocidal principles obtained from oakmoss absolute were identified as methyl 2, 4-dihydroxy-3, 6-dimethylbenzoate (2), ethyl 3-formyl-2, 4-dihydroxy-6-methylbenzoate (4), and ethyl 5-chloro-3-formyl-2, 4-dihydroxy-6-methylbenzoate (7). In relation to their structures, the nematocidal activity of 2, 4-dihydroxybenzoates of methyl to tetradecyl was tested and the strongest activity was found in the octyl ester (minimal lethal concentration=13 μM).
从橡树苔中提取的杀线虫物质被鉴定为 2,4-二羟基-3,6-二甲基苯甲酸甲酯(2)、3-醛基-2,4-二羟基-6-甲基苯甲酸乙酯(4)和 5-氯-3-醛基-2,4-二羟基-6-甲基苯甲酸乙酯(7)。根据它们的结构,测试了甲基至十四烷基的 2,4-二羟基苯甲酸酯的杀线虫活性,发现辛酯的活性最强(最小致死浓度=13 μM)。
