Chinese J. of Guangdong Agr. Sci. (9), 103-105 (2012). Garlic (Allium sativum L.) contains high levels of carbohydrates (up to 75 %), the main of which are fructo oligosaccharides (FOS). FOS have antioxidative activity. The quality control of garlic has to monitor the content of FOS because it changes during its storage. TLC of the extracts of garlic on silica gel twice with n-butanol – isopropanol – water – acetic acid 7:5:4:2, detection by spraying with vanillin – sulfuric acid – ethanol – water 3:13:81:26 and heating at 100 °C for 5 min. Up to seven monosaccharides in garlic are well separated by using the procedure.
