Isolation and Structural Investigations of Green Pigment (Gp) from Pineapple Peels

Abstract

This study describe the philosophy of Green Chemistry Principles when applied to the treatment of pineapple peels waste. Green pigments were isolated and identified from pineapple fruit peels extracts by using renewable methods like two phase system extraction (TPE) by ether: acetone at 40°C. The extract was analyzed and purified via flash column chromatography under certain condition (FCC) .The fractional components monitored with thin layer chromatography (TLC) at room temperature and identified utilizing spectroscopic analysis tools such as UV-visible, FT-IR, 1H-NMR ,13C-NMR and GC-Mass analysis .Two components of green pigments (GP) were identified .They are chlorophyll types(a) and (b) respectively.The advantages of this method include friendly environment, low cost of preparation, isolation, identification, and ease of scale detection.
