摘要: Six plant crude extracts were chosen to evaluate their acaricidal activity against Tetranychus cinnabarinus adults. The extract from the stems and leaves of Arachis hypogaea L. presented highest in leaf‐dip bioassays, with an LC₅₀ value 3,545.98 mg/L. Further extraction using four different solvents (petroleum ether, ethyl acetate, n‐butyl alcohol distilled water) demonstrated that active components mainly existed petroleum ether phase. Then, compound, palmitic acid, was isolated phase via two‐step column chromatography columns filled silica gel C‐18 identified mass spectrometry nuclear magnetic resonance analyses. acid T. cinnabarinus 534.58 mg/L. present study compound extracted A. hypogaea is a potential novel botanical acaricide for controlling T. cinnabarinus.
