Isolation of chemical constituents from methanol extract in stem bark of pithecellobium jiringa / Nosafarina Abdul Manaf

This study is designed to isolate and identify chemical constituents from the
methanol extract in stem barks of Pithecellobium jiringa. The chemical
constituents from methanol extract were isolated and purified by using liquid liquid
extraction, silica gel in column chromatography and were analyse by using
GC-MS and FT-IR techniques. The structures of the chemical constituents were
identified on the basis of spectral data on GC-MS, and FT-IR. n-Hexadecanoic
acid, Hexadecanoic acid (ethyl ester), 1,2,4-Trioxolane-2 octanoic acid, 5-octyl (methyl ester),
Eicosane and two of Hexadecanoic acid (methyl ester) constituents
at different peaks were isolated from methanol extracts of stem barks of
Pithecellobium jiringa. The results suggested that the current studies on
Pithecellobium jiringa is still far from being well known and therefore more
studies need to be done for better understanding of this plant.
