IDENTIFICATION OF THE ISOLATED COMPOUNDS FROM Zingiber amaricans BL. RHIZOME
ABSTRACT: Five extracts were
obtained from extraction of rhizomes of Zingiber amaricans. Hexane,
dichloromethane and methanol extracts were obtained by maceration, while
dichloromethane and acetone extracts the resulted of soxhlet extraction. By
column chromatography technique 2,6,9-humulantrien-9-one (zerumbone) was
isolated as the major constituent of the hexane, dichloromethane and methanol
extracts. The minor constituents were phytosterol mixtures isolated from hexane
and dichloromethane extracts. The mixtures consisted cholesterol, campesterol,
stigmasterol and β-sitosterol. The
structure elucidations of zerumbone was
confirmed by spectroscopic method, whereas the phytosterol mixtures was
identified by gas chromatography-mass.
