The essential oil extracted by n-Hexane solvent extraction and hydro-distillation of Arabian jasmine flowers collected from Pothohar region was analyzed by GC/MS. Concrete oil recovery on fresh petal weight basis was 1.78 g (0.17%) and absolute oil recovery from this concrete was 0.09%. Essential oil recovery in hydro-distillation was 0.08 g (0.008%). The colour of absolute oil was very light b...

ABSTRAK Ekstraksi adalah suatu proses pemisahan zat berdasarkan perbedaan kelarutannya terhadap dua cairan tidak saling larut yang berbeda. Pengambilan ekstrak minyak atsiri dapat dilakukan dengan tiga metode yaitu penyulingan atau destilasi, ekstraksi menggunakan pelarut, dan melalui pengepresan penekanan.Pada percobaan ini digunakan untuk mengekstrak dari daun sereh wangi cara penyulingan. Ad...

The essential oil from flowering aerial parts of Nepeta macrosiphon Boiss. growing wild in Kermanshah Province, Iran, was analyzed by GC/MS. This essential oil was prepared by a modified Likens-Nickerson’s simultaneous distillation-extraction (SDE) method. Forty-five compounds consisting 95.1% of the total components were identified from the oil obtained with a yield of 0.1%w/w. Among them, spa...

essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. lythrum salicaria has not been previously subjected to examination of its volatile oil. the present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (hd) and microwave a...

Quantum channels underlie the dynamics of quantum systems, but in many practical settings it is themselves that require processing. We establish universal limitations on processing both states and channels, expressed form no-go theorems quantitative bounds for manipulation general channel resources under most transformation protocols. Focusing class distillation tasks -- which can be understood...

Star anise (Illicium verum) is widely used as a medicinal herb and spice. The extracts, essential oil oleoresin, can be produced by hydro-distillation steam distillation, while solvent supercritical fluid extraction to extract oleoresin. In this work, the star distilled obtain oil, subsequently, its residue extracted get Whole grounded fruit for 8, 12, 16, 20, 24 hours, thus highest yield obtai...

The volatile constituents obtained from Juniperus communis berries by the application of different methods, Hydro distillation (HD), Super Critical Fluid Extraction (SFE) and Headspace (HSE) static technique were examined as regards their qualitative and quantitative composition. Significant differences were noticed among the percentages of the main components of the extracts: the monoterpene h...
