Study of Antioxidant and Larvicidal Properties of Selected Medicinal Plants of Fringe Villages of Manas National Park, Assam, India

A study on medicinal plants from the fringe villages of Manas National Park, Assam, India, reveals that Cinnamomum tamala exhibits strong antioxidant and larvicidal properties, with significant potential as a natural mosquito repellent. The research found that C. tamala had the highest phenolic and flavonoid content (up to 147.15 µg GAE/mg and 28.43 µg QE/mg, respectively) and demonstrated potent antioxidant activity, with an IC50 value as low as 15.05 µg/mL in certain assays. Additionally, it showed strong larvicidal effects against Aedes aegypti larvae, with an LC50 of 3.11 mg/mL, outperforming other tested plants. The findings suggest that C. tamala could serve as a promising alternative to synthetic insecticides, particularly in regions where mosquito-borne diseases are prevalent.
