Subcritical Water Extraction of Essential Oils from Matricaria Chamomilla L.
Subcritical water extraction (SWE) of essential oil from Matricaria Chamomilla L. (M. Chamomilla L.) was performed and compared with conventional method including hydro distillation. The percentage of main extracted components of different temperatures (100, 125, 150 and 175 oc) and water flow rates (1, 2 and 4 ml/min) were investigated at 20 bar pressure and 0.50 mm mean particle size in SWE....
متن کاملSubcritical Water Hydrolysis Treatment of Waste Biomass for Nutrient Extraction
Nutrients were extracted from corn stalks, peanut shells, de-oiled peanut meal, chicken manure, and sewage sludge by a subcritical water (SCW) hydrolysis reaction. Compared with the other feedstock, the aqueous phases extracted from de-oiled peanut meal showed the highest watersoluble organic carbon, amino acid, total nitrogen, and phosphorus contents. The effects of solution pH, final hydrothe...
متن کاملExtraction of Quercetin from Polygonum Hydropiper L. by Subcritical Water
The new method of quercetin extraction from Polygonum hydropiper L. by subcritical water was developed. High performance liquid chromatography was used for identification and quantification of flavonoids in the extract. The new method is environmentally friendly and more effective (7.6-times) than traditional flavonoids extraction methods using expensive and toxic organic solvents.
متن کاملExtraction of Bioactive Components from Centella Asiatica Using Subcritical Water
Centella asiatica is a tropical medicinal plant with a long history of therapeutic uses, dermal disorders, venous insufficiency and microangiopathy. The substances of therapeutic interest are the saponin-containing triterpene acids and their sugar esters. Two bioactive components, asiatic acid and asiaticoside, were extracted from Centella asiatica using subcritical water as an extraction solve...
متن کاملSubcritical-Water Extraction of Organics From Solid Matrices
An apparatus for extracting organic compounds from soils, sands, and other solid matrix materials utilizes water at subcritical temperature and pressure as a solvent. The apparatus, called subcritical water extractor (SCWE), is a prototype of subsystems of future instrumentation systems to be used in searching for organic compounds as signs of past or present life on Mars. An aqueous solution g...
