Optimization of Subcritical Water Extraction of Polysaccharides from Inonotus Obliquus and their Antioxidant Activities
Subcritical water extraction (SWE) of Inonotus Obliquus polysaccharides (IOP) was investigated using response surface methodology (RSM) with a design by Box–Behnken design (BBD). Results showed that the optimum SWE conditions for IOP production were as follows: extraction temperature 194°C, residence time 5.36 min and liquidsolid ratio 53 mL/g, yielding 168.80 ± 0.59 mg/g of IOP, which was in c...
متن کاملSubcritical 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 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 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.
