The process of amygdalin extraction from plum seeds was optimized using central composite design (CCD) and multilayer perceptron (MLP). The effect of time, ethanol concentration, solid-to-liquid ratio, and temperature on the amygdalin content in the extracts was estimated using both mathematical models. The MLP 4-3-1 with exponential function in hidden layer and linear function in output layer ...

In the work described here, two techniques for the recovery of anthocyanins from potato peel were studied and compared. One of the techniques employed was supercritical fluid extraction (SFE) with pure CO2 or with CO2 and ethanol as cosolvent and the other technique was pressurized liquid extraction (PLE), where the solvent used was ethanol in water acidified to pH 2.6. The effects of pressure ...

By use of fungi grown in the presence of [3H]-inositol and [14C]choline, we have explored methods for the quantitative extraction of inositol-containing phospholipids and phosphatidylcholine. Slightly alkaline mixtures of both ethanol-water and ethanol-diethylether-water at elevated temperatures were shown to effectively extract these lipids from intact Saccharomyces cerevisiae and Neurospora c...

Microalgae have increasingly gained research interest as a source of lipids for biodiesel production. The wet way processing of harvested microalgae was suggested and evaluated with respect to the possible environmental impacts and production costs. This study is focused on the three key steps of the suggested process: flocculation, water recycling, and extraction of lipids. Microalgae strains ...

The aim of the present study was to determine the antioxidant activity of Coreopsis tinctoria flowering tops (CTFT). Studies were conducted to obtain suitable extraction conditions for chlorogenic acid, quercetin, luteolin, apigenin and kaempferol, which were identified and quantified by HPLC. Response surface methodology was employed to optimise the ultrasound-assisted extraction conditions in...

BACKGROUND DNA extraction from paraffin wax embedded tissue requires special protocols, and most described methods report an amplification success rate of 60-80%. AIMS To propose a simple and inexpensive protocol consisting of xylene/ethanol dewaxing, followed by a kit based extraction. METHOD Xylene/ethanol dewaxing was followed by a long rehydration step and a kit based DNA extraction ste...

Bioherbicides are an alternative to minimize the damage caused environment using agrochemicals. This study had objective of extracting neem oil from ripe waste fruits that Azadirachta indica A. Juss and optimizing process solvents (or a mixture solvents) with different polarities. Then, through solid-liquid extraction system (Soxhlet), hexane, methanol/hexane (1:1), ethanol, hexane/ethanol (1:1...

Abstract This paper reports the results of supercritical carbon dioxide (scCO 2 ) extraction β-carotene from Dunaliella salina as potential alternative to conventional organic solvent extraction. In pilot-scale scCO experiments, pressure, temperature, and co-solvent concentration were varied. The at 500 bar, 70 °C, 10 wt% ethanol yielded in highly efficient pigment recovery over 90%. Techno-eco...

a comparative study of ultrasound-assisted extraction (uae) and hydro-distillation was performed for fast extraction of estragole from tarragon (artemisia dracunculus l.) dried leaves. several influential parameters of the uae procedure in the extraction of estragole (type of solvent, extraction cycles, solvent to material ratio, irradiation time and particle size) were investigated and optimiz...
