Abstract

Guava leaves (Psidium guajava L.) have been documented as a rich source of phytochemicals with potential health benefits. This study aimed to investigate the effects of selected solvents on the polyphenols content and the antioxidant activity of guava leaf (Psidium guajava L.) extracts. Ethanol 70%, methanol 70%, and hot water are selected solvents. Total phenolic content (TPC) and total flavonoid content (TFC) were determined to evaluate the efficient recovery of polyphenols..
