Abstract:
Objective: Nyctanthes arbortristis is a common plant in Bangladesh. The objective of our research was to biochemical and biological analysis of the methanolic extract of the dried leaves of Nyctanthesarbortristis found in Bangladesh. Methods: We investigated the presence of polyphenols, flavanoids and other types of compounds by thin layer chromatography, infrared spectroscopy, and UV spectroscopy analysis. We performed antioxidant assay by colorimetric methods. We investigated antibacterial assay by disk diffusion method. Cell surface receptor binding assay was performed by hemagglutination inhibition assay and hemolysis assay. Results: Methanolic extract of the leaves of Nyctanthes arbortristis contains flavanoids and other biologically active compounds. The extract showed antioxidant, peroxide scavenging and total reducing activity. The extract also showed antibacterial activities against several strains of bacteria. It also showed hemaglutination inhibition activities and hydrogen peroxide induced hemolysis inhibition activity in human blood cells. Conclusions: Therefore, Nyctanthes arbortristis may be considered as a plant of various health benefits.
