ABSTRACT
Flavonoids are important not only for their roles in floras but similarly for their medicinal and nutraceutical applications. Flavonoids are a family of plants that can be found in various concentrations in an inclusive range of plant species. Flavonoids are secondary plant metabolites that play a key part in the biological activity processes of plants. They are dependable for the color characteristic of flowers and fruits. They also take part in symbiosis between plants and microbes. Flavonoids are a class of bioactive chemicals present in a wide range of plant-based foods. Flavonoids are classified into subgroups that establish their chemical arrangement, containing flavones, flavanones, flavonols, flavanonols, anthocyanins, and isoflavones. The determinable and subjective examination of flavonoids has been supported by the metabolomics technique. Flavonoids are a broad set of compounds found in agricultural crops, and researchers have used metabolomics technologies to examine flavonoid composition using various analytical approaches. Allelopathy is currently studied as an organic management of weeds and insect pests, as well as a way to alleviate stress and contamination in consideration of boosting yield output in order to tackle many problems in agriculture. The main objective of this study is to give an outline of their uses and demonstrate that metabolomics is a useful means for studying flavonoid metabolism in various agricultural crops.
