UV-Vis scanning coupled with PCA as an alternative method for phytochemical screening of natural products – Costus Igneus leaf metabolites

Abstract

Utilization of medicinal plants to discover new drugs and to invent nutraceuticals and functional foods is the current trend for natural product researchers and food technologists. Availability of cost effective and reliable methods to identify the functional groups and bioactive molecules from natural products are scarce. In this study the patterns of absorbance at different wavelengths by the bioactive compounds were detected using principal component analysis of the absorbance data of extracts of Costus igneus plant leaf. Thin layer chromatography method and qualitative phytochemical screening chemicals methods were done simultaneously. Principal component analysis depicted significant correlation (p
