Evaluation of Anti-Parkinson Activity of Aqueous Extract of Barleria prionitis

Abstract

AIM- The aim of the preset investigation is Evaluation of Anti-Parkinson Activity of Aqueous Extract of Barleria prionitis. MATERIAL & METHODS- The whole plant of Barleria prionitiswere collected from the surrounding areas of Erode district, Tamilnadu, India during the month of December. Coarsely powdered whole plant of Barleria prionitis were extracted with water for 48 hours at room temperature. After extraction the extracts were evaporated by using rotary evaporator and dried at room temperature. The obtained crude extracts were weighed and stored at 4ᵒC for the further analysis. Male Swiss albino mice 3 month of age, and 25-30 g body weight were offered. All the rats were kept at room temperature and allowed to acclimate in standard conditions less than 12 hr light/ 12 hr dark cycle in the animal house. The MPTP was purchased from sigma chemicals, Mumbai, India and was stored according to the manufacturer label (370C) to prevent its decomposition. The length of time (duration) the animal stay on the rod without falling, gives a measure of their coordination, balance, physical condition and motor-planning. RESULTS- The grip strength of treated rats were found to be increased in the rats as compared to untreated rats. Similarly, Locomotor activity were also significantly increased in the rats treated in rats as compared to untreated rats. DISCUSSION- From the results the Actophotometer readings (locomotor activity) of animals of vehicle-treated control group (Group I) was found to be 386.33±1.56 and 396±1.15 counts/5 min for all 7 days of treatment. MPTP treatment to animals of Group II showed a significant reduction in locomotor activity every week. The actophotometer readings decreased to 186±2.30 counts/ 5 min. on the 7th day, went down to 145.33±0.23 counts/5 min. Thus, there was a significant decline in the locomotor activity of rotenone treated control animals (Group III) when compared to vehicle-treated control group (Group I). CONCLUSION- From the present study, it can be considered that the aqueous extract of Barleria prionitis exhibited significant anti-parkinsonism activity in MPTP model in mouse and rats respectively.
