Microwave-assisted and ultrasound-assisted extraction assays were used to isolate total flavonoids (TF) from Osmanthus fragrans flowers. The effects of the solid-liquid ratio, ethanol concentration, microwave power, microwave extraction time, ultrasonic power and ultrasonic extraction time on the yield of TF were studied. A sequential combination of microwave- and ultrasound-assisted extraction...

Background & Aim: A simple and rapid microwave- assisted extraction (MAE) procedure was developed and optimized for the isolation of borneol and bornyl acetate from Ferulago macrocarpa. Ferulago macrocarpa (Apiaceae) is an endemic plant in Iran. Experimental: Dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a Clevenger extraction app...

A microwave-assisted hydrodistillation protocol was modified to extract essential oils from leaves of Salvia triloba L. and Laurus nobilis L. The essential oils of these plants are generally obtained by hydrodistillation or steam distillation. The volatile compounds obtained by microwave-assisted hydrodistillation and hydrodistillation methods were analyzed by GC and GC/MS. Both distillation me...

An accurate method based on combination of microwave assisted digestionsuppressed ion chromatography is proposed for the determination of fluoride and chloride in nuclear grade enriched boron (B10). The digestion of the boron matrix is carried out in closed vessel microwave assisted digestion using hydrogen peroxide and dilute nitric acid. By using the microwave assisted approach, the digestion...

background: pentachlorophenol (pcp) is one of the most fungicides and pesticides. acute and chronic poisoning from pcp may be occurred by dermal absorption, and respiration or ingestion. with respect to health and environmental effects of pcp, many methods were considered regarding its removal. microwave assisted other methods are environmental friendly, safety, and economical method, consequen...

The genus Haplophyllum, which belongs to the Rutaceae family, includes 18 species in Iran. In this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of Haplophyllum robustum Bge. were extracted by three different isolation techniques, conventional hydrodistillation (HD), microwave-assisted hydrodistillati...

The microwave assisted synthesis nowadays attracts a great deal of attention. Monoclinic phase VO2 (M) was prepared from NH4VO3 and H2C2O4 · 2H2O by a rapid microwave assisted technique. The synthesis parameters, microwave irradiation time, microwave power, and calcinations temperature were systematically varied and their influences on the structure and morphology were evaluated. The microwave ...

Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. This review was conducted to introduce and compare the conventi...

The major challenges for industrial commercialized biodiesel production from microalgae are the high cost of downstream processing such as dewatering and drying, utilization of large volumes of solvent and laborious extraction processes. In order to address these issues the microwave irradiation method was used to produce biodiesel directly from wet microalgae biomass. This alternative method o...
