Structural Characterization of Chlorogenic Acid and Myricetin Flavonoids from Indian Plantation White Sugars

Chlorogenic acid and myricetin are natural flavonoids found in many medicinal plants, is well known for its rich pharmacological activities. This paper describes the flavonoids composition of the plantation white sugar and the method of isolation thereof. A simple method for the simultaneous determination of chlorogenic acids and myricetin content in plantation white sugar has been reported. Two unknown sugar flavonoids were isolated from sugar by using resin-based column chromatography. After filtration, the colorant solution was adsorbed on to the gel column at a flow rate of 1ml/3min, and elution was done with water at the same rate. 10 ml fractions were collected which were then chromatographed on cellulose TLC plates. The pure fractions were completely evaporated and investigated for identification. Flavonoids structures were elucidated by Rf value, UV and NMR spectroscopic techniques, and chromatography. This is the first report of chlorogenic acid and myricetin as cane sugar pigments that can be used as natural antioxidants in food or non-food products.
