Microwave-Assisted Extraction of Cannabinoids in Hemp Nut Using Response Surface Methodology: Optimization and Comparative Study.
Hemp nut is commonly incorporated into several food preparations; however, most countries set regulations for hemp products according to their cannabinoid content. In this study, we have developed an efficient microwave-assisted extraction (MAE) method for cannabinoids (i.e., Δ9-tetrahydrocannabinol, cannabidiol, and cannabinol) in hemp nut. Optimization of the MAE procedure was conducted throu...

Betulinic Acid from Zizyphus Joazeiro Bark Using Focused Microwave-Assisted Extraction and Response Surface Methodology
BACKGROUND The effect of the extraction time (min) and temperature (°C) on the yield of betulinic acid (BA) from Zizyphus joazeiro barks using focused microwave-assisted extraction was investigated. MATERIALS AND METHODS The ethyl acetate was used as extractor solvent because it was shown to provide a betulinic acid-clean extract. A full two-level statistical factorial design was applied to d...
متن کاملOptimization of Microwave-assisted Extraction of Flavonoids from Cryptotaenia japonica Hassk using Response Surface Methodology
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 ...
متن کاملOptimization of Microwave Assisted Alkaline Extraction of Xylan from Birch Wood Using Response Surface Methodology
The main purpose of this study was to optimize microwave assisted alkaline extraction of the hemicellulose, xylan, from birch wood. The simultaneous effects of process variables such as time (10 30 minutes), concentration of sodium hydroxide solution (4 8 wt%), solid to liquid ratio (1:8 to 1:20, g:mL), and sample size (5 10 g) on the temperature of the wood slurry, wood dissolution, and yield ...
