Abstract

Antioxidant plays essential roles in the maintaining of good health. Fruits and vegetables are the primary sources of antioxidants. Antioxidant contents in fruits and vegetables could vary in geographical distribution and also in the same soil for different time intervals. Therefore, the present study aimed to analyze the total antioxidant status and proximate analysis of some selected locally available fruits and vegetables and they were Mangiferaindica, Musa acuminate, Psidium guajava, Carcia papaya, Lagenariasiceraria, Trichosanthesdioica, Momordica charantia, Basella alba, and Amaranthus gangeticus from three villages. In this analysis, total antioxidant status was determined by DPPH free radical scavenging assay, and proximate analysis of moisture, ash, fat (Soxhlet extraction method), and protein (Kjeldahl method with N × 6.25) were determined as the method outlined in AOAC (2005). Among the four fruits sample, Papaya hadthe highest moisture content (88.08%)but was lower in ash, protein, fat, and carbohydrate contents. Among the vegetables, Bottle gourd had the highest moisture content (94.14%).Regarding all samples, Red amaranth showed the highest ash (1.59%) and protein (4.32%) content. However, both Mango and Papaya showed the lowest protein content (0.70%). Fat content was low in Papaya and Bottle gourdwith 0.10% and 0.15% respectively. For the carbohydrates, Banana was the greatest source with 22.62%. Furthermore, among the fruits Guava had the highest total antioxidants activity of 70.90% and among vegetables, Bitter gourd had 45.47% which was the highest compared to other studiedvegetables. Whereas, Indian spinachhad the lowest antioxidants activity and the value was 28.60%. The above results indicate that the selected fruits contents higher levels of antioxidant activity compared to selected vegetables samples.

Highlights

In recent years, increasing attention has been paid to the role of fruits and vegetables in the diet and human health
The bottle gourd from Ambottola village had the highest level of moisture (95.18%) than all the fruits and vegetables from three villages
Red amaranth showed the lowest level of moisture in vegetables group and that was 84.38%

Summary

Introduction

In recent years, increasing attention has been paid to the role of fruits and vegetables in the diet and human health. Higher fruits and vegetables intake are related to a healthy diet pattern correlated with lower CHD (chronic heart disease) incidence rates and negatively associated with the consumption of saturated fat-rich food.[9,10,11] fruits and vegetables are the main sources of antioxidants, which are the phytochemicals that prevent some of the processes of developing cancer and cardiovascular diseases.[12] Antioxidants prevent the oxidation process of lipids or other molecules by hindering the initiation of oxidizing chain reactions where redox reactions are fundamental for the biological processes.[13] In the Human body, at the time of ATP (adenosine triphosphate) production, cells use oxygen and release free radicals by the mitochondria. Where reactive oxygen species (ROS) and reactive nitrogen species (RNS) are produced as a result of the cellular redox process.[14]
