Garlic (Allium sativum L.) husk waste as a potential source of phenolic compounds: Influence of extracting solvents on its antimicrobial and antioxidant properties

Evaluation of Antioxidant Activity from Different Plant Parts of Senduduk Herb: Extraction Conditions Optimization of Selected Plant Part

“…However, the further increase in solvent concentration up to 100% results in the decrease of antioxidant activity. This is in agreement with Fatma et al, [10] that stated the extraction using a mixture of organic solvent and water could promotes higher recovery of antioxidant phenolic compounds as compared using of pure organic solvent due to the polarity effects. Therefore, acetone with concentration of 80% was selected as the best concentration of solvent to extract antioxidant activity from flower of Senduduk herb.…”

“…However, the declined trends were observed in antioxidant activity when the solvent concentration was kept increase to 90%. This might be due to a decrease in polarity of acetone as more polar solvent will facilitates the extraction of phenolic compound [10]. …”

Determination of Essential and Non-essential Metals Concentration in Garlic (<i>Allium sativum</i> L.) Bulb and Leaf Cultivated in Ambo Woreda, Ethiopia

“…Garlic has been used throughout its history for both culinary and medicinal purposes [2]. Garlic (Allium sativum L.) is the most widely used bulb vegetable next to onion in Ethiopia.…”

Recent patents on the application of bioactive compounds in food: a short review

“…Several agricultural and industrial residues represent a great alternative as raw material of bioactive compounds production and have been studied as sources of potentially safe natural additives with antimicrobial and/or antioxidant properties for the food industry [4].…”

“…Important factors in the process are solvent type, extraction time and temperature [9]. Solvents or co solvents with different polarities such as ethanol and water [5,10,11] and/or organic solvents [4,6,7] can be employed for solid-liquid extractions in heat-reflux systems. Furthermore, non-conventional methods (ultrasound, pulsed electric field, enzyme digestion, extrusion, microwave heating, ohmic heating, supercritical fluids) are more environment friendly due to decreased use of synthetic and organic chemicals and reduced operational time, enhancing extract yield and quality [9].…”
