Abstract

Impact of Environmental Factors on Secondary Metabolite Diversity and Free Radical Scavenging Activity of V .vinefera Jumbo Seedless From Nashik Valley

Highlights

Secondary metabolites are known for their multiple functionality and bioactivity due to presence of more than one functional groups. [1]
The tests were identified by visual observation of colour change or by precipitate formation on addition of specific reagents to the test solution
Methanolic extracts of leaf lamina, stem and petiole were tested for the presence of different secondary metabolites

Summary

Introduction

Secondary metabolites are known for their multiple functionality and bioactivity due to presence of more than one functional groups. [1]. Uniform plants growing at higher altitude showed higher antioxidant activity compare to plants at lower altitude [7,8].High altitudes and effect of enhanced UV-B radiation on contents of secondary metabolites has been discussed by Korner,1999 [9].The correlation of low temperature with increase of antioxidant secondary metabolite are described by .Ncube,2011.Enhanced productivity of phenolic compounds absorbing, UV-B with antioxidant is reported in response to enhanced UV-B radiation where, enhanced production is a protective response against damage from excessive UV-B radiation due to their UV-shielding properties [10,11].Soil nutrients and soil water availability has direct interlink with biosynthesis of secondary metabolites .Their abundance or limited availability has effect on contents of secondary metabolites in plants .Biosynthesis of secondary metabolites is dependent of photosynthetic rate which is affected by duration and intensities of stress factors and limits the carbon and energy distribution for the biosynthesis of secondary metabolites and quantitatively affect their levels in plants .In addition to climatic factors, biotic stress factor is one of the important factors in which plants are exposed in environment of multiple herbivore and pathogenic attacks.
