Microwave-Assisted Extraction of Phenolic Compounds from Almond Skin Byproducts (Prunus amygdalus): A Multivariate Analysis Approach.
A microwave-assisted extraction (MAE) procedure to isolate phenolic compounds from almond skin byproducts was optimized. A three-level, three-factor Box-Behnken design was used to evaluate the effect of almond skin weight, microwave power, and irradiation time on total phenolic content (TPC) and antioxidant activity (DPPH). Almond skin weight was the most important parameter in the studied resp...
متن کاملSynthesis and Evaluation of Fatty Hydrazides Based on Schiff Bases from Oil Processing Industries Byproducts
Schiff bases of fatty acid hydrazides made from Oil recovered from spent bleaching earth (ORSBE) and Acid oil (AO)were prepared. These newly synthesized Schiff bases were characterized on the basis of FT-IR, elemental analysis and evaluated for biological performance. Schiff bases exhibited mild antibacterial activities against certain micro-organisms if compared with streptomycin used as stand...
