Investigation on chemical constituents of essential oils from Achillea mellifolium L. subsp. mellifolium by distillation methods
The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

متن کاملComparison Extraction Methods of Essential oils of Rosmarinus officinalis L. in Iran By Microwave Assisted Water Distillation; Water Distillation and Steam Distillation
Rosmarinus officinalis L. is a perennial herb that belongs to the Lamiaceae family. It is used as a food flavouring agent, and well known medicinally for its powerful antimutagenic, antibacterial and chemopreventive properties. The most applicable method for extraction of essential oil is water distillation (WD) and steam distillation (SD). It is a traditional technique which is used in most in...
متن کاملTools for Teaching Batch Distillation Inductively using Process Simulation
One approach to active learning involves taking students through a guided exploration process; one which ensures students will observe phenomena and then be asked questions intended to draw conclusions regarding the observations. In recent years, this has been called inductive teaching, but more recently the expression “inquiry-based instruction” or related terms have become more common. Concur...
متن کاملHomogeneous azeotropic pressure swing distillation: continuous and batch process
The separation of a binary homogeneous azeotropic mixture using pressure swing distillation will be analysed on the example of acetonitrile/water. Two different processes are considered: the continuous heatand mass-integrated process and the inverted batch process. For both processes a model is developed and experimental data are given. In the paper the potential of the pressure swing distillat...
