Unconventional source of anise volatile oil

Recycling agricultural waste plays a positive role in getting rid of the remnants of plants and reduces the proportion of environmental pollution,especially in agricultural areas,in addition to optimization of the economic situation in egypt. this work intended to discuss the discovery of new and unconventional ways to produce essential oils. it amid to examine and evaluate anise oil extracted from new plant materials such as herb and waste (remnants of post-harvest) as new sources of anise essential oil. the chemical constituents of anise ( pimpinella anisum) oils were analyzed by means of gc and gc/ms. the results of anise oil analysis showed that,nineteen constituents representing 68.72% of the oil herb were identified,against twenty one (93.12 %) and nineteen constituents (84.88 %) for seed and waste oil,respectively. in all cases,the major component of essential oils is anethole < trans > which amounted to 52.17,65.58 and 62.72 % in the oil extracted from herb,seeds and waste,respectively. all oils were rich in oxygenated monoterpenes (om) compared with other terpene groups. the om recorded (62.87%) in herb oil against 81.24 and 79.87 % in the oil of seeds and waste of anise,respectively. significant compounds were detected in the oil of herb,seeds and waste of anise. from the compounds detected in the oils were,estragole,eugenyl acetate,germacrene d,anethole < cis- > and linalool. some new compounds were identified in the egyptian anise oil,such as butyrate,isopentyl n-butyrate,myrtenal,p-anisaldehyde,methyl eugenol,cuparene,nuciferol < e- > and eugenyl acetate . © 2017,university of mohammed premier oujda morocco.
