Jyotishmati (Celastrus paniculatus) seeds are widely used in Ayurvedic formulations for learning and memory, but they are usually extracted with conventional methods such as maceration that give relatively low yields. This study compared those methods with two greener techniques — microwave-assisted and ultrasound-assisted extraction — and optimized them using a statistical design approach. The optimized green extracts gave higher yields and richer phenolic and flavonoid content, along with stronger antioxidant and acetylcholinesterase-inhibiting activity. The extracts were then tested in rodents with memory impairment induced by scopolamine. The optimized extracts reversed the memory impairment more effectively than conventionally prepared extracts and improved markers of oxidative stress. The work links how Jyotishmati is extracted to the strength of its biological activity.
Key Learnings
- Optimized Jyotishmati seed extracts reversed scopolamine-induced memory impairment in rodents.
- They performed better than extracts made by conventional methods.
- Antioxidant activity and oxidative-stress markers both improved.
- The study shows that extraction method directly affects the concentration and activity of plant actives.
- The memory findings come from an animal model — human effects were not assessed.
