Perfil Químico Fixo e Semivolátil de Sementes de Melancia por Gc-Ms e Hplc-Dad

Abstract

It is a known fact in the literature that the bacterium A. citrulli is the pathogen responsible for watery spot disease in melons and watermelons, the which infection of the fruit and as seeds. In view of the economic importance of watermelon culture for Tocantins, especially for municipalities such as Lagoa da Confusão and Formoso do Araguaia, in addition to its national relevance, the present work proposals to investigate the compounds present in infected watermelon samples and healthy using HS-SPME / GC-MS (Headspace-Solid Phase Microextraction/Gas Chromatography–Mass Spectrometry) and HPLC-DAD (High Performance Liquid Chromatography-Diode Array Detector) techniques. As the result not only detects differences in the compounds present or absent, but it abundance of phenolic compounds that allows possible the deduce of treat yourself defense of the plant for an infection. It is relevant that there is more research, mainly of collaboration between research groups, to obtain more complete results, which allows the creation of economically viable pesticides while being environmentally safe.
