Antibacterial, Antioxidant Activity and Phyto-Chemical Screening of Prunus armeniaca (L.) var. (Hari & Khobani) Leaf Extracts

Abstract

Antibacterial and antioxidant properties of different varieties (Hari and Khobani) of Prunus armeniaca L. in methanol, water, ethyl acetate and chloroform were studied. Antibacterial activities of various leaf extracts were tested against Staphylococcus aureus, Klebsiella pneumonia, Proteus vulgaris and Escherichia coli. Ampicillin was used as standard antibiotic. Aqueous and methanol extracts showed significant activities whereas ethyl acetate and chloroform extracts showed least activity. Methanol extracts of Prunus armeniaca L. Hari and Khobani showed IC₅₀ value of 0.21mg/ml and 0.01mg/ml respectively. Qualitative phyto-chemical study of aqueous and methanol extracts of Prunus armeniaca showed the presence of saponins, glycosides and flavonoids in both varieties. The comparison between antibacterial activities showed that both varieties of Prunus armeniaca L. (Hari and Khobani) were significantly different from each other. Hari showed highest antibacterial activities than Khobani. Both varieties could be used for therapeutic purpose.
