Abstract:

The structure of apigenin was modified by sulfonation reaction with concentrated H2SO4, and water-soluble sodium apigenin sulfonate was obtained. Its structure was characterized by IR, MS and 1H -NMR spectroscopic techniques. The best reaction conditions for producing water-soluble sodium apigenin sulfonate were: ratio of apigenin to concentrated sulfuric acid 1:6 (g/ml), and temperature 15 ℃ for a reaction duration of 60 min. Under the conditions, and the yellow acicular crystals of sodium apigenin sulfonate were obtained with the yield of 83.5%.

Key words: apigenin, sulfonation reaction, structure characterization
