Abstract:Diabetes mellitus is a long-term condition marked by elevated blood glucose levels. It is a leading cause of morbidity and mortality worldwide. Diabetes is linked to heart disease, particularly coronary artery disease. Plant-based diets, which include fruits, vegetables, herbs, and spices, are thought to be a good source of phytonutrients that can improve one's health. The presence of non-nutritive secondary metabolites known as phytochemicals, which contain numerous physiologically active moieties, has been related to the capacity of several plant-based meals to reduce the risk of chronic diseases. These phytonutrients' bioactivity has been linked to their antioxidant properties, as they scavenge free radicals, which are responsible for the development of various serious degenerative illnesses such as LDL oxidation, DNA oxidation, inflammation, and ageing. The Syzygium jambolanum is one of the valuable antidiabetic plants and a significant medicinal resource in many traditional medical systems, sometimes referred to as black plum and initially indigenous to India. The seeds include phenols, polyphenols, jambosine, alkaloid, and glycoside antimellin or jambolin, inhibiting the diastatic conversion of starch into sugar.
Objective of our study are, preparation and extraction of Jamun seed extracts, and characterization of the extracts using UV-Visible spectroscopy, Phytochemical screening of seed extracts and test on glucose using seed extracts. Here three different extracts, ethanol+water, pure ethanol and pure methanol have been used. All the extracts were placed in UV-Visible spectroscopy to check their absorbance. Glucose solution with different extracts were tested to check the glucose breakdown using UV-Visible spectroscopy.
All three extracts with jamun seed showed promising result in breaking down of the glucose, but pure ethanol extract showed the maximum breaking down of the glucose and it showed highest percentage of phenol and alkaloids are present, so these compounds in various food systems can be used in efficacious dose for humans, it is possible to develop nutraceuticals or functional foods for diabetic patients.
