Mangiferin is a xanthone widely distributed in higher plants showing antioxidative, antiviral, anticancer, antidiabetic, immunomodulatory, hepatoprotective and analgesic effects. In the present study, an ultrasonic-assisted extraction method was developed for the effective extraction of mangiferin from mango leaves. Some parameters such as ethanol concentration, liquid-to-solid ratio, extractio...

To utilize starch and protein contained in microalgae as carbon and nitrogen sources for ethanol production, an extraction method, i.e. ultrasonic treatment using a homogenizer, and simultaneous saccharification and fermentation (SSF) of extracted microalgae solution were studied using Chlamydomonas fasciata Ettl 437. 30 min of ultrasonic treatment gave the maximum extraction ratio of starch co...

Cannabis-based products are still not produced in many countries and the great need makes them imported, often expensive. As an objective, a low-cost extraction method was proposed to facilitate access medicinal effects of cannabidiol. The samples Cannabis sativa used were obtained from vitro cultivation or commercially purchased products. Two techniques (ultrasonic turbo-extraction) two solven...

This research was undertaken to investigate the influence of extraction parameters during microwave-assisted extraction on total phenolic content, total flavonoids, total hydroxycinnamic acids and total flavonols of blackthorn flowers as well as to evaluate the antioxidant capacity by two different methods (2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and ferric reducing antio...

The Thelephora ganbajun mushroom has been found to be a potential rich source of natural antioxidants. In this study, an ultrasound-assisted extraction (UAE) technique together with GRAS (generally recognized as safe) solvents (ethanol and water) was used to maximize the extraction of antioxidants from Thelephora ganbajun. Five extraction parameters (ethanol concentration, solvent to solid rati...

World wine industry transforms 10% 25% of raw grapes into residues, mainly represented by lees, grape marcs, seeds and stems. These byproducts are a rich source of polyphenols and therefore they can be used to produce new added value products. The aim of this work was to determine the best process conditions (treatment time, % of ethanol and pH of the solvent) during solid-liquid extraction of ...

In this study is presented a general methodology to predict the performance of a continuous near-critical fluid extraction process to remove compounds from aqueous solutions using hollow fiber membrane contactors. A comprehensive 2D mathematical model was developed to study Porocritical extraction process. The system studied in this work is a membrane based extractor of ethanol and acetone from...

This work aims to study the impact of solvent mixture (between 0 and 50% ethanol/water mixture) and temperature (between 25°C and 75°C) levels on the solid-liquid extraction of phenolic compounds (quantity and bioactivity) from apricot pomace. Results show that the mean augmentation of 1% ethanol in the range [0-12%] enhances by three times the extraction of polyphenols compared to the same aug...

The functionality of gluten extracted from Canada Western Red Spring (CWRS) and Canada Western Extra Strong (CWES) wheat flours was evaluated and compared. The extra-strong wheat cultivars had stronger dough properties and produced smaller bread loaves than AC Barrie. Modifications of a starch displacement gluten extraction method were evaluated. For optimal gluten formation and extraction, wat...

The objective of the study was to optimize the processing of Microwave-Assisted Extraction (MAE) of flavonoids from Cryptotaenia japonica Hassk. The effects of processing parameters include ethanol proportion, extraction time, extraction temperature and ratio of liquid to solid on the flavonoids yield were determined and the optimal conditions for flavonoids were evaluated by means of Response ...
