This experiment was conducted to bring in a suitable and economic agarwood oil extraction method for Agar tree (Aquilaria agollocha) growers in Bangladesh. Agarwood was collected from Fotikchori upazila of Chittagong district and a prototype of hydro-distillation extraction chamber was developed at the lab of Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh...

This paper introduces the krypton sampling and extraction facilities currently developed at the Centre for Science and Peace Research to collect and extract the krypton content from small air samples. The extraction unit able to isolate the krypton in small ambient air samples with high speed and high efficiency using a combination of cryogenic distillation and gas chromatography. Air samples a...

Essential oils (EOs) from Abies sachalinensis (Sakhalin fir), a conifer species found in Sakhalin Island and Hokkaido Japan, effectively remove nitrogen dioxide possess antifungal activity. EOs also exert relaxing effect enhance air quality. Underwater shock waves generate instantaneous high pressure that ruptures cell walls, enhancing the performance of steam distillation oil extraction. In th...

Background and objectives: It is necessary to specify the best conditions of essential oils production to get more major compound(s) and higher yield oil. The fennel oil is useful in pharmaceutical industry as flavor. The main component of fennel oil is anethole (55-75%). The objective of this work was to identify the effect of  particle size, pH of water, method of distillatio...

Syzygium aromaticum L. is an aromatic plant with a significant amount of essential oil (EO), which used in food, medicine, for flavoring, and the fragrance industry. The purpose this study was to comparatively evaluate chemical composition, yield, antioxidant antifungal activities oils extracted by conventional hydro-distillation, steam distillation, emerging superheated distillation methods. I...

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...

Microwave extraction and separation has been used to increase the concentration of the extract compared to the conventional method with the same solid/liquid ratio, reducing extraction time and separate at the same time Volatile Organic Compounds (VOC) from non-Volatile Organic Compounds (NVOC) of boldo leaves. As preliminary study, a response surface method has been used to optimize the extrac...
