Parkinson's disease (PD) is characterized by progressive locomotive defects and loss of dopaminergic neurons. leaves are used by Vietnamese as herbal medicines to support the treatment of some diseases related to neurodegeneration such as Parkinson's and Alzheimer's diseases. However, recent scientific data have not provided sufficient evidence for the use of leaves to treat PD or decelerate PD progression. In the present study, the capacity of leaf extract for PD treatment on the dietary supplementation was investigated using dUCH-knockdown model. The results indicated that leaf extract decelerated dopaminergic neuron degeneration induced by dUCH knockdown in not only the larval stage but also the adult stage, which might result in the amelioration in locomotor ability of dUCH-knockdown larvae and flies. Furthermore, antioxidant activities and some key phytochemicals such as saponins, polyphenols, and flavonoids that might contribute to the effects of the leaf extract were identified.
