Microwave assisted extraction of phenolic compounds from four different spices.
Spices and herbs are known not only for their taste, aroma and flavour, but also for their medical properties and value. Both spices and herbs have been used for centuries in traditional medical systems to cure various kinds of illnesses such as common cold, diabetes, cough and cancers. The aim of this work was the comparison between two different extractive techniques in order to get qualitati...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Optimization of Ultrasonic-Assisted Extraction of Phenolic Compounds from Apples
In order to optimize conditions for the extraction of polyphenols from apples, peel and flesh of apples were subjected to an extraction process with different solvents consisting of various ratios of methanol and water (40, 60, 80 %), 100 % methanol, or with methanol acidified with hydrochloric acid (0.1 %). Extractions were performed using an ultrasonic bath with time periods from 5 to 15 min....
متن کاملExtraction and Antioxidant Activity of Phenolic Compounds from Okra Flowers
Purpose: To investigate the extraction and antioxidant activity of phenolic compounds from Okra flowers. Methods: The phenolic compounds in Okra flowers was obtained by traditional solvent extraction method and determined by Folin-Ciocalteu (FC) method. The extraction was optimized using response surface methodology (RSM). The antioxidant activity of the obtained extract was determined by 1,1di...
