| Summary: | Cysteine and glutathione (GSH) are important low molecular mass thiols or sulfhydryl
compounds that play numerous important roles in metabolism. They also have myriads
of applications in industry including pharmaceutical, cosmetic and foods. These
compounds naturally occur in plants but less was focused on extracting them from plant
sources. Garlic is of particular interest as potential source for thiol compounds since it
contains high concentration of organosulfur which correlates with the presence ofcysteine and GSH. In this work, water-based ultrasonic assisted extraction was used toextract thiols from garlic bulbs. The effect of garlic concentration and amplitude of sonicator on thiol concentration was investigated. The optimal garlic concentration of
10 % (w/v) was able to extract 0.170 mMthiols and 100 % amplitude of sonicator corresponds to the highest value of thiol compounds obtained. |
