Compounds identified in plant extracts applied to agriculture and seed treatment

ABSTRACT: Plant extracts effects have been regarded and proven in researches under different applications in agriculture, including seed treatment. The plant extracts effectiveness is attributed to the presence of certain classes of compounds; therefore, studies that aim to identify and quantify these composites, which are present in plant extracts used in agriculture, are important, as well as the seed treatment. This research aimed to understand and describe through a systematic review, what were the main carried approaches, classes and identified compounds in studies with plant extracts to different applications in agriculture and the seed treatment. The period 2015 to 2020 was the one that exposed the higher research publication indexes, considering the theme under analysis, plant extracts in agriculture, seeking to identify or quantify the presence of metabolic composites, indicating a growing interest in this theme. Such studies pursued identifying and/or quantifying the compounds that are present in the plant extracts. The phenolic compounds constitute the priority class of metabolites to different functions, effects and applications in agriculture, mainly in seed treatment. The terpenes present a substantial potential as bioinsecticides to agriculture. Plant species that are rich in phenolic and terpenes compounds are a significant source of alternative control in the protection of the productive system.

摘要：植物提取物的功效已在多项涵盖农业不同应用场景（包括种子处理）的研究中得到认可与实证。植物提取物的功效源于其所含的特定类别化合物，因此，旨在识别并定量分析农业用植物提取物中此类成分的研究，与种子处理相关研究均具有重要价值。本研究通过系统综述的方式，旨在阐明针对农业不同应用场景（含种子处理）开展的植物提取物相关研究中，所采用的主要研究方法、化合物类别以及已被鉴定出的活性成分。就本研究分析的主题——农业领域用于识别或定量分析代谢成分的植物提取物研究——而言，2015年至2020年是该领域研究发文量最高的时期，反映出学界对该主题的关注度持续提升。此类研究均围绕植物提取物中化合物的识别与/或定量分析展开。酚类化合物是满足农业领域多种功能、功效及应用需求的首要代谢物类别，在种子处理场景中尤为关键。萜类化合物则具备作为农业生物杀虫剂的巨大应用潜力。富含酚类与萜类化合物的植物物种，是农业生产系统保护中替代传统防治手段的重要资源。
