Abstract
The zebrafish obesogenic test (ZOT) is a powerful tool for identifying anti-adipogenic compounds for in vivo screening. In our previous study, we found that Moringa oleifera (MO) leaf powder suppressed the accumulation of visceral adipose tissue (VAT) in ZOT. MO demonstrates a wide range of pharmacological effects; however, little is known about its functional constituents. To identify the anti-adipogenic components of MO leaves, we prepared extracts using different extraction methods and tested the obtained extracts and fractions using ZOT. We found that the dichloromethane extract and its hexane:EtOAc = 8:2 fraction reduced VAT accumulation in young zebrafish fed a high-fat diet. We also performed gene expression analysis in the zebrafish VAT and found that CCAAT/enhancer-binding protein beta and CCAAT/enhancer-binding protein delta (associated with early stages of adipogenesis) gene expression was downregulated after fraction 2 administration. We identified a new MO fraction that suppressed VAT accumulation by inhibiting early adipogenesis using the ZOT. Phenotype-driven zebrafish screening is a reasonable strategy for identifying bioactive components in natural products.
