Chemical composition of essential oil in dried fruits of Xylopia aethiopica from Sudan

Abstract

The essential oil from the dried fruit of Xylopia aethiopica (Dunal) A. Richard from Sudan was analyzed using combined GC-MS and 1 HNMR. The main constituents identified in the oil were 4-terpineol (11.30%), ?-pinene (6.12%), ?-terpineol (6.02%), 1,8-cineole (5.42%), cis -?-copaene-8-ol (4.68%),13-epimanoyl oxide (4.62%), (+)-spathulenol (4.26%), L-pinocarveol (3.26%), myrtenol (2.94%), o-cymene (2.82%), eudesma-1,3-dien-11-ol (2.35%), eudesma,4-11(13)-dien-2-ol (2.32%), cumic alcohol (2.29%), Kaur-16-ene (2.21%) and ?-pinene (1.88%). Fifteen compounds were identified for the first time in X. aethiopica essential oil, among which thujol, 1,5-epoxysalvial,4(14)-ene, salvial-4(14)-en-1-one and 13-epimanool were the major compounds.
