Abstract:

Lotus () leaves are widely used for both edible and medicinal applications. For its further utilization, we studied the vasodilatory activity of lotus leaf extract for the first time. In this study, we obtained the extracts using different ratios of water and ethanol, which was followed by polarity-dependent extraction. We found that the CHCllayer exhibited better vasodilatory activity (EC= 1.21±0.10 μg/ml). HPLC and ESI-HRMS analysis of the CHCllayer using the standard product as a control revealed that nuciferine (E= 97.95±0.76%, EC= 0.36±0.02 μM) was the main component in this layer. Further research revealed that nuciferine exerts a multi-target synergistic effect to promote vasodilation, via the NO signaling pathway, Kchannel, Cachannel, intracellular Carelease,αandβreceptors, etc. Nuciferine exhibits good vasodilatory activity, and it exhibits the potential to be utilized as a lead compound.
