Background: Piper longum, a traditional plant used for regenerative medicine commonly known as the long pepper, is used to treat many pathological conditions. Piper longum is used as a source for obtaining the production of various nanoparticles and testing their efficacy. Piper longum has many beneficial activities, such as antifungal, anti-amoebic, anti-asthmatic, anti-cancer, anti-oxidant, anti-inflammatory, antidepressants activities. Silver nanoparticles are widely and commonly used for its antimicrobial activity against various microorganisms. Our study aimed to synthesize Piper longum based silver nanoparticles and to investigate its anti-oxidant property. Materials and Methods: Piper longum plant extract was prepared and silver nanoparticles extract was synthesized. DPPH assay was then performed to assess the free radical scavenging activity of the Piper longum silver nanoparticle extract. The further analysis was that the formation of brownish-red color observed was evident, resulting in thesynthesization of silver nanoparticles. Results: Brown discolouration represents formation of silver nanoparticles and the antioxidant activity was noted to be from 60% to 70% from 10 to 50μL. But when compared to standard vitamin C values the Piper longum silver nanoparticles showed less antioxidant activity. Conclusion: The Piper longum mediated silver nanoparticles showed remarkable and considerable antioxidant activity but when compared with the standard sample values the antioxidant activity was low.

Human Identification is a very important process in Forensic Investigations. Accordingly, Lip Prints and Palatal Prints plays a crucial role in identifying an individual person. In sex determination cheiloscopy and palatoscopy helps to find out the person and it can produce infront of court of law. It is helpful in finding the missing individual and it can be applicable in mass disaster instances.
