Extraction, Phytochemical profile, and neuroprotective activity of fruit extract against sodium valproate-induced postnatal autism in BALB/c mice.

The aim of the present study was to evaluate the effect of the ethyl acetate fraction of amla (EAFA) extract on valproic acid (VPA)-induced postnatal autism in BALB/c mice. Our study revealed that mice treated with VPA on postnatal day 14 (PND14) showed significant abnormal behaviours such as social interaction, social affiliation, anxiety, and motor coordination compared to the control group, while EAFA extract treatment (100 mg/kg) ameliorated these symptoms. Our study highlights the protective effect of EAFA extract on improving behavioural alterations, significantly restoring anti-oxidative enzymes such as GST and GR, and reducing MDA and NO levels. Furthermore, the EAFA-treated group significantly lowered the proinflammatory markers (IL-1β and TNF-α) and the expression of up-regulated 5-HT1D, 5-HT2A, and D2 receptor proteins. Based on histopathological studies, the percentage of neuronal injury in the EAFA-treated group as well as cellular structural changes were reduced using SEM analysis. In conclusion, the present study suggests that treatment with EAFA extract ameliorates VPA-induced autism due to its anti-oxidant and neuroprotective activity.
