Abstract:

Psidium guajava or typically recognized as guava is useful to deal with gastroenteritis, dysentery, stomach pain and indigestion. In this study, the leaves of this species were screened for its phytochemical and antioxidant activity. The phytochemicals have been extracted by sequential maceration with the aid of the usage of n-hexane, chloroform and methanol, whilst phytochemical screening was once performed the usage of various chemical tests. Meanwhile, its antioxidant exercise was assessed by using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. Steroids and terpenoids were located to be existing in the n-hexane extract, whilst phenols and terpenoids had been detected in the chloroform extract. The methanol extract contained flavonoids, steroids, saponins, phenols and terpenoids. Among the tested extracts, the methanolic extract confirmed robust DPPH radical scavenging undertaking with an IC50 value of 44.72 μg/mL.
