Abstract
Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by the loss of dopaminergic neurons and the exist of alpha-synuclein aggregates in the substantia nigra pars compacta (SNpc). Among the various types of neuroprotective therapy, natural products are potential therapeutic agents for PD. Objective: The aim of this study is to describe the neuroprotective effect of herbal plant extracts against Parkinson's Disease (PD). Method: The search strategy was carried out on electronic databases, namely Google Scholar, ScienceDirect, and PubMed. There are 111 scientific journals that have been filtered into 20 scientific journals which are international journals published in the last 5 years (2015-2020). The keywords used include Parkinson's Disease, Neuroprotective Effects, Neuroprotection, Plant Extracts, Natural Products and Parkinson's Disease Model. Results: Several experimental studies have shown the neuroprotective ability of various plant extracts to protect against neurotoxicity, through several neuroprotective pathways including antioxidant activity, anti-inflammatory activity, and antiapoptotic activity. Conclusion: Herbal plant extracts have been shown to have strong neuroprotective effects, making them as potential drug candidates for prevention or treatment of Parkinson's Disease (PD). There are Mucuna pruriens, Centella asiatica, Camellia sinensis, Ginkgo biloba, and Uncaria rhynchophylla. Keywords: Parkinson's Disease (PD), neuroprotective, extract.
