Abstract

Fruits and vegetables are the food sources that serve as healthy food to provide additional physiological benefit, beyond the basic nutrition due to their richness in bioactive phytochemicals such as polyphenols and carotenoids that serve both nutrients as well as protection against maladies. Psidium guajava L. plant belongs to the family Myrtaceae, commonly known as guava is cultivated as flora in tropical and sub tropical region. The fruits of this plant are consumed daily and known for its medicinal value from folk medicine. The aim of present study was to analyze the phytochemical constituents in extracts of guava fruit. The extracts under study were made from fruit peel, pulp, and seeds of guava fruit by employing solvents like ethanol, ethyl acetate, methanol, sterile distilled water. The parameters studied are organoleptic characters, extractive values, phytochemical constituents [alkaloids, flavonoids, saponins, tannins, glycosides, and amino acids] were analyzed in the variety of fruit extracts. The total phenolic content of fruit extracts was evaluated spectrophotmetrically according to Folin-Ciocalteu phenol method and expressed in gallic acid equivalents [GAE]. Results showed that organoleptic characters were the color for fruit peel was green, pulp was white and seeds were creamy and the taste was bitter and palatable. The odor was leafy and aroma and the texture were rough. The extractive values, phytochemical screening and phenol content for extracts from peel, pulp and seeds was in better alcoholic solvents like ethanol and methanol. This study reveals the P. guajava fruit extracts are moderate potential sources of natural antioxidants.
