Plant produces a large number of phenolic compounds with several biological activities. Phenolics such as phenolic acids, flavonoids and tannins are considered to be the major contributor to the antioxidant ability of plants. These antioxidants of the plant also possess diverse biological activities, such as anti-carcinogenic, free radical scavenger, anti-atherosclerotic and anti-inflammatory, activities. These all activities are related to their antioxidant capacity. Phenolic compounds contribute evidently to
antioxidative action and they constitute the major class of natural antioxidants present in plants; therefore, it is necessary to calculate total phenolic content in plant species. In present study, using Folin-Ciocalteau method we found different response from three different samples in various concentration for each which were quantitively expressed as mg GAE/g of extract. Here, sodium carbonate produces blue color of phosphormolybdicphosphor tungstic phenol complex. Thus, most concentrated blue color contains highest total phenolic content. According to results G. sylvestre has the highest amount of phenolic content than C. frutescens and A. bilimbi. Present studies indicate the presence of polyphenolic compound in G. sylvestre, C. frutescens and A. bilimbi.
