FTIR-ATR based fingerprinting and chemometrics analysis of metabolites profile of Phyllanthus niruri L. affected by fertilization with NPK-chitosan nanopolymer and harvesting age

Abstract

Introduction: Phyllanthus niruri L. (PnL) is a herbaceous plant containing flavonoid quercetin and can be used as an immunomodulator to prevent Covid-19. However, the flavonoid content and yield of herbs extract were not maximized. Therefore, PnL herbs were planted in various harvest periods and application of NPK-chitosan nanopolymer fertilizer to estimate these parameters.
