Abstract
Due to the great interest in obtaining natural bioactive carbohydrates to be used as functional ingredients, a selective microwave assisted extraction (MAE) method was optimized to ensure the exhaustive extraction of inositols and α-galactooligosaccharides (α-GOS) from mung bean. Thereafter, a comprehensive characterization of these compounds was carried out by gas chromatography coupled to mass spectrometry (GC-MS). Apart from free inositols and α-GOS, several glycosyl-methyl-scyllo-inositols and glycosyl-inositols were detected for the first time in this legume. Under optimized MAE conditions (0.5â¯g dry sample, 2 cycles of 3â¯min, 50â¯Â°C, 10â¯mL 50:50 ethanol:water, v:v), bioactive carbohydrates yields were similar to those found using solid-liquid extraction (SLE), but with shorter analytical times. Concentrations of bioactive carbohydrates in MAE extracts from samples of different geographical origins ranged between 74.1 and 104.2â¯mg.gâ1 dry sample. MAE was proved a good alternative to SLE to obtain extracts enriched in bioactive carbohydrates.
