Classification and Identification of Flavonoids from plant kingdom as Acacia species (original) (raw)

Flavonoids, a group of natural substances with variable phenolic structures, are found in fruits, vegetables, grains, bark, roots, stems, flowers, tea and wine. These natural products are well known for their beneficial effects on health and efforts are being made to isolate the ingredients so called flavonoids. Flavonoids are now considered as an indispensable component in a variety of nutraceutical (are products, nutrition are also used as medicine), pharmaceutical, medicinal and cosmetic applications. This is attributed to their antioxidative, anti-inflammatory, anti-mutagenic and anticarcinogenic properties coupled with their capacity to modulate key cellular enzyme function. In this study we try to classify the flavonoids from higher plant specially Acacia species. Various sub groups of flavonoids are classified according to the substitution pattern of ring C. Flavonoids classified into: flavones, flavanols, flavanones, chalcones, aurones, isoflavonoids and anthocyanins .The chemical structure of the all types of flavonoids can be deduced on the basis of its Infrared(IR),Ultra violet (UV), proton nuclear magnetic resonance (1 H NMR) Spectrophotometer.
