Exploring phytochemical diversity and antioxidant potential in leaves extracts: A comparative study of Psidium guajava (Guava) and Terminalia chebula (Myrobalan)

Abstract

The investigation delved into the biochemical analysis of leaf extracts from Psidium guajava (Guava) and Terminalia chebula (Myrobalan), revealing the presence of vital phytochemicals. Total phenolic contents (TPC) were quantified at 101.791 mg/ml for Psidium guajava and 133.795 mg/ml for Terminalia chebula, while total flavonoid contents (TFC) exhibited higher values in Psidium guajava (42.2869 mg/ml) compared to Terminalia chebula (36.4787 mg/ml). Remarkably, Psidium guajava leaf extract displayed robust antioxidant activity, displaying a remarkable 93.44% inhibition at 250μg/ml. Terminalia chebula extract, on the other hand, demonstrated maximum inhibition (92.55%) at a concentration of 350μl/ml. These findings underscore the distinctive biochemical profiles and potent antioxidant potential of the studied extracts, providing insights into their promising applications in the realm of natural health and wellness. Moreover, the phytochemicals present in Psidium guajava and Terminalia chebula leaves attributed to antimicrobial properties make them also suitable for treating textile materials, endowing them with antimicrobial activity.
