Comparative Study on Anti-Acetylcholinesterase and Anti-Inflammatory Activities of Date and Apple Vinegars Fortified with Centella Asiatica

Abstract

Neuroinflammation and deficiency of cholinergic are major factors of neurodegenerative damage correlated to cognitive impairment in Alzheimer’s disease (AD). We investigated the anti-inflammatory and anti-acetylcholinesterase activities of apple and date vinegars added with Centella asiatica in SH-SY5Y neuroblastoma cells. The neuroprotective effect of apple or date vinegar added with various percentage of C. asiatica (0, 0.5, 2, 5) % w/v was determined in vitro. The methanolic extract of apple vinegar added with 2% C. asiatica (AV-2% CA) and date vinegar added with 2% C. asiatica (DV-2% CA)  extracts showed potent neuroprotective effect. Both extracts were subjected to liquid-liquid partitioning yielded aqueous (H2O: AV/DV-2% CA) and ethyl acetate (EA: AV/DV-2% CA) extracts. Anti-inflammatory response against nitric oxide (NO) of all extracts was measured in LPS-induced SH-SY5Y neuroblastoma cells and percentage inhibition of acetylcholinesterase (AChE) was measured using commercially available test kits. It was found that EA: DV-2% CA showed potent ameliorating effect against LPS-induced inflammation (I50: 563.5 ± 0.13μg/mL) and was also responsible in the AChE inhibition activity (IC50: 9.087 ± 0.02). Thus, this extract is suggested to have dual properties of anti-inflammatory and anti-acetylcholinesterase inhibition activity that could be beneficial in the treatment and prevention of neurodegenerative disease.
