Phytochemical, proximate, anti-inflammatory and antimicrobial activity of Psidium guajava

Psidium guajava, or guava, is used in traditional medicine for a wide range of conditions, including diarrhea, diabetes, high blood pressure, respiratory issues like coughs, and various infections. The present study aimed to address phytochemical studies, in vitro antioxidant activities, screening of antimicrobial activity and in vitro anti-inflammatory activity of Psidium guajava. The phytochemical and proximate analysis was done by usual method. Agar well diffusion method and protein denaturation method was carried out for antimicrobial and anti-inflammatory screening. The results showed that the presence of various phytochemical. The proximate composition shows that the plant has high carbohydrate (38.25%), moderate concentration of protein (6.56%) and low concentration of fat (5.15 %). Alkaloids were found to be the most abundant one followed by tannins and flavonoids while phenols and saponins were least in concentration. In our knowledge aqueous extract of Psidium guajava showed a potential antioxidant, antimicrobial and anti-inflammatory activity because of its high secondary metabolites.
