In this work, different extraction techniques (soxhlet extraction, hydrodistillation, subcritical water and supercritical carbon dioxide followed by conventional extraction) were employed for the isolation of bioactive compounds from areal parts industrial hemp (Cannabis sativa L.). The process parameters, time temperature pressure, on yield content examined. As plant material after still conta...

BACKGROUND Gongronema latifolium Benth. (GL) possesses considerable glucose lowering effects able to be utilized on a large-scale. This paper investigates the effects of a Soxhlet extract on hyperglycemia, Langerhans islets and glucose uptake by abdominal muscles. METHODS Ethanol and a Soxhlet apparatus were used to obtain GL ethanolic Soxhlet extract (GLES). It was then administered to rando...

The aim was to determine the conjugated linoleic acids in beef with GC-FID. Perfect separation of all of the isomers cannot be achieved, though conjugated linoleic acid isomers proved to be separable from the other fatty acids that are present in beef in a significant amount related to conjugated linoleic acids. Lipid-extraction was carried out with n-hexane/i-propanol, giving 6.8 percent highe...

Supercritical fluid extraction of the volatile oil of the aerial part of the winter savory was carried out in different conditions of pressure, temperature, mean particle size and CO2 flow rate and the results were compared with those obtaining by hydrodistillation with a Clevenger-type apparatus. The non-volatile components were extracted by SFE at higher pressures and by soxhlet extraction wi...

In the last years the supercritical fluid extraction has been frequently used to obtain volatile oils from aromatic plants. In this work we have applied this technique to a different vegetable matrix: poplar (Populus nigra and MC) buds as it is known that they contain antioxidant compounds. The results of the supercritical extraction have been compared with those of the conventional soxhlet ext...

Currently microalgae are considered as an efficient biological producer of oil.Present study was conducted to explore the lipid yield percentage three microalgal strains Chlorellasp., Oedogonium sp. and Spirogyra Bligh Dyer, Soxhlet, Folch Microwave assistedextraction methods were employed for oil extraction. It observed that Dyer method withChloroform-methanol (1:2, v/v) gave maximum extractio...

Seeds are another product in addition to leaves (raw materials for teas) of tea (Camellia sinensis L.) plant. The great increase of tea consumption in recent years raises the challenge of finding commercial applications for tea seeds. In the present study, supercritical carbon dioxide (SC-CO(2)) extraction edible oil from tea seed was carried out, response surface methodology (RSM) was used to ...
