Classification of pomegranate cultivars by multivariate analysis of biochemical constituents of HPLC

Abstract

Pomegranate fruits are highly diverse and may be divided into geographical groupings based on their characteristics. Genetic research has verified these categories in recent years and further categorized variants into geographic-genetic groupings. This study aimed to assess the biochemical contents of eight varieties of pomegranate fruit seed and the categorization of pomegranate using multivariate statistical analysis. Polyphenolic chemicals are key secondary metabolites in pomegranate, and their presence influences the quality and sensory qualities of the fruit they produce. Fruit extracts from the Faqyan cultivar contained the highest total phenolic content of all studied cultivars. Pomegranate cultivars such as Shaqlawa, Halabja Sour, and Faqyan were shown to have the highest antioxidant activity. Gallic acid, caffeic acid, chlorogenic acid, p-coumaric acid, cinnamic acid, rutin, apigenin, rosmaric acid, and quercetin were the most abundant phytochemical components in the study. According to the results of multivariate analysis, pomegranate cultivars were divided into four major groups. The pomegranate fruit seed is the most abundant source of antioxidants and beneficial phytochemical elements. Finally, the Sidakan Sweet and Shaqlawa cultivars included a significant content polyphenolic compounds.
