Phytochemical screening and antioxidant activity of Psidium guajava
Psidium guajava or commonly known as guava is useful to treat gastroenteritis, dysentery, stomach pain and indigestion. In this study, the leaves of this species were screened for its phytochemical and antioxidant activity. The phytochemicals were extracted by sequential maceration by using n-hexane...

| description | Psidium guajava or commonly known as guava is useful to treat gastroenteritis, dysentery, stomach pain and indigestion. In this study, the leaves of this species were screened for its phytochemical and antioxidant activity. The phytochemicals were extracted by sequential maceration by using n-hexane, chloroform and methanol, while phytochemical screening was performed using various chemical tests. Meanwhile, its antioxidant activity was assessed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Steroids and terpenoids were found to be present in the n-hexane extract, while phenols and terpenoids were detected in the chloroform extract. The methanol extract contained flavonoids, steroids, saponins, phenols and terpenoids. Among the tested extracts, the methanolic extract demonstrated strong DPPH radical scavenging activity with an IC50 value of 45.52 μg/mL.\

Psidium guajava atau dikenali sebagai jambu batu berguna bagi mengubati gastroenteritis, disenteri, sakit perut dan masalah
pencernaan. Dalam kajian ini, daun spesis ini telah disaring untuk fitokimia dan aktiviti antioksidan. Fitokimia telah diekstrak
menggunakan rendaman berturutan menggunakan n-heksana, kloroform dan metanol, manakala saringan fitokimia telah
dijalankan menggunakan pelbagai ujian kimia. Sementara itu, aktiviti antioksidan telah dinilai menggunakan kaedah 2,2-difenil1-pikrilhidrazil (DPPH). Steroid and terpenoid telah didapati hadir di dalam ekstrak n-heksana, manakala fenol dan terpenoid
telah dikesan di dalam ekstrak kloroform. Ekstrak metanol telah mengandungi flavonoid, steroid, saponin, fenol dan terpenoid.
Di kalangan ekstrak yang diuji, ekstrak metanol menunjukkan aktiviti perencatan radikal DPPH yang kuat dengan nilai IC50
45.52 μg/mL. |
