Anti-Angiogenesis Screening of Moringa oleifera Pod Extracts by In-Ovo Chorioallantoic Membrane (CAM) Assay

Abstract

Moringa oleifera has many therapeutic benefits one out of it is anti-cancer property. Therefore, many researchers have been screening the therapeutic potential of Moringa oleifera. The main objective of this study was to screen and explore the angiogenesis inhibition potential of Moringa oleifera pod extracts. With the aim of screening anti-angiogenic potential, extracts of Moringa oleifera pods were prepared by decoction method. The extracts were subjected to preliminary phytochemical screening to identify the nature of phytochemicals present in the pods. In-ovo chorioallantoic membrane assay was chosen to achieve the objective of the study. Water-soluble extractive value (15.00% w/w) was higher than that of alcohol-soluble extractive value (3.89% w/w), indicating that the Moringa oleifera pods have more water-soluble constituents. Qualitative phytochemical screening revealed presence of flavonoids. Angiogenesis inhibition effect was studied and compared with sunitinib. Statistical analysis revealed highest anti-angiogenesis activity in 100% methanolic extract. Least effect was observed in 50% aqueous extract. Anti-angiogenic potential of 100% methanolic extract was statistically significant when compared with other study groups. It is concluded that Moringa oleifera pods exert anti-angiogenic potential and more intensified and diversified studies are needed to enable a thorough investigation of this plant components in anti-cancer treatment.
