ABSTRACT

Zephyranthes rosea, member of the family Amaryllidaceae, contains a rich source of several neuroactive alkaloids, including Galantamine, with established relevance in Alzheimer's disease management. While the bulb constituents have been investigated previously, the biological potential of the leaves remain largely unexplored.

The present study aimed to characterize the phytochemical composition of ethanolic extract of Z. rosea leaves (ZRLE) by GC–MS and to evaluate its antioxidant and acetylcholinesterase inhibitory activities, along with its cytotoxicity and neuroprotective efficacy against aluminium-induced neurotoxicity in SH-SY5Y cells.

GC–MS identified 33 phytochemicals in ZRLE, including galantamine-related alkaloids. The extract demonstrated notable antioxidant activity as well as moderate AChE inhibition. Cytotoxicity studies showed an LC₅₀ of 85.38 µg/mL in SH-SY5Y cells. Aluminium chloride markedly reduced cell viability, while extract pre-treatment significantly attenuated neurotoxicity and restored cell viability with observable morphological protection. These findings suggest that ZRLE exerts significant neuroprotective activity.
