Anti-Aging Activity and Non-Toxic Dose of Phytooxyresveratrol from Artocarpus lakoocha Roxb
Purpose: To determine the anti-aging activity and toxicity doses of phytooxyresveratrol extracted from Artocarpus lakoocha Roxb.
Methods: Artocarpus lakoocha 100 g was extracted with 2 ml of 95 % ethanol to obtain phytooxyresveratrol (POV). Total phenolic content, as well as free radical scavenging and anti-glycation activities of POV were characterized in order to assess its anti-aging properties. The models of DNA nicking and bacterial reverse mutation (Ames) were applied to the extract in order to determine its effective and toxic doses, respectively.
Results: Phytooxyresveratrol (POV) exhibited antiaging activity. It also showed high levels of phenolic content, radical scavenging activity and anti-glycation. A POV concentration of 25 μg/ml promoted strong anti-DNA nicking. Furthermore, it was non-toxic at concentrations ranging from 5 - 100 μg/ml.
Conclusion: In vitro, phytooxyresveratrol (POV) extracted from Artocarpus lakoocha exerted effective anti-aging activity at a concentration of 25 μg/ml. Thus, the substance should be further studied for possible formulation into pharmaceutical products.
