Abstract:
The present study was planned to determine the effect of extraction techniques (mechanical shaking, refluxing, soxhlet extraction, and centrifugation) and solvents (acetone, ethanol and water) on antioxidant activity of turmeric rhizomes. Soxhlet extraction technique was found to be most efficient extraction technique for turmeric rhizomes as extracts obtained by soxhlet possess highest antioxidant activity. Amongst solvents, acetone extracts exhibited highest antioxidant activity. Extract yield and sugars content were estimated and their contents were also found to be highest in soxhlet extracts.
