Özet: Anthocyanins are the most important of flavonoid pigments of plants. Researches shown that anthocyanins have important roles in floralpigmentation, additionally, they serve functions in plants as signalling to micro-organisms, protecting against pathogens, ameliorating bioticand abiotic stress. Anthocyanins have a 15-carbon base structure comprised of two phenil rings as called the A and B ring. Connected by athree carbon bridge that usually forms a third ring as called C-ring. An increased number of hydroxyl groups on B rings of anthocyanins hasa blueing effect on the color. Three basic types of anthocyanins, pelargonidin (orange and pink colours), cyanidin (magentha colour) anddelphinidin (purple and blue colours) are occured according to the degree of hydroxilation. Flowers can also accumulate mixtures ofanthocyanin types, providing furter variation in colour. Improvements in methods and instrumentations used for analysis of anthocyaninshave made it easier and more sensitive. The number of identified anthocyanins are excess of 600, thus specific solvents and methods requiredfor individual anthocyanin analysis. Proper extraction and isolation procedure shall be follow by chromatographic seperation and purificationmethods. Last step is quantification with specroscopic technics. In this article is compiled the chemical properties of anthocyanins and releateto analytic technics.
