Background: Curculigo orchioides Gaertn, a plant belonging to the Hypoxidaceae family, is well-known for its traditional uses of all plant parts. This plant is commonly known as golden eye grass, black musli, Kali musli, or Kali Musali. Parkinson's disease is a neurodegenerative disorder that is commonly observed in older adults. It is caused by a variety of mechanisms, including neuroinflammation, which results in the loss of dopamine release when triggered and causes motor symptoms. Methods: Ethanolic extract was prepared by shade-drying the leaves, making them into a coarse powder, and the extract was prepared by maceration technique with the help of ethanol. GCMS analysis and Haloperidol-induced Parkinsonism study were carried out to evaluate the antiParkinson activity in albino Wistar rats. Ethanolic extract of Curculigo orchioides was subjected to GCMS analysis. The National Institute of Standards and Technology database was used to interpret the mass spectrum of the GC-MS. The screening models were catalepsy, rotarod and a few in vitro models, namely the estimation of catalase acetylcholinesterase levels. The animals were divided into 6 groups, namely control, disease, standard (levodopa), low dose (100 mg/kg p.o.), medium dose (200 mg/kg p.o.), high dose (400 mg/kg p.o.) groups having 6 animals each were used for rotarod and catalepsy models for 14 days Results: The results obtained showed a dose-dependent increase in the anti-Parkinson activity. The evaluation of neuromuscular movements of the ethanolic leaf extract of Curculigo orchioides showed that the pre-treatment with different ranges of dose (100 mg/ml, 200 mg/kg, and 400 mg/kg) suggested a dose-dependent significant increase in fall-off time when compared with both standard and disease groups GCMS analysis revealed the presence of flavonoids, Vitamin and fatty acid esters. Conclusion: The anti-Parkinson activity of Flavonoids has been reported previously. Hence, the activity may be attributed to kaempferol-3-O-glucuronide.
