Abstract

Nymphaea pubescens is one of the floating plant species that can be widely found in the wetland area like rivers and lakes across Malaysia and Southeast Asia. It is traditionally used in Philippines as medicinal plant in treating gonorrhea and as a sleep inducer. Currently there are a few conventional and modem methods of extracting essential oils such as distillation, organic solvent extraction, supercritical fluid extraction and microwave extraction. Work done in this research identified that essential oil can be extracted from Nymphaea pubescens by organic solvent extraction. The yield of essential oil extracted by hexane from IO g leaves sample was 0.180 g and from 10 g stems sample was 0.108 g. While, for methanol extraction, yield of essential oil extracted from 10 g leaves sample was 6.310 and from 10 g of stems sample was 5.772 g. Identification of functional groups of the essential oil were done using FT-IR spetrophotometer and showed that it may contain alcohols, phenols, carboxylic acids, esters, alkanes, phenyl rings, and nitrites.
