Inflammation is the body's immune response to combat suspected harmful effect by a stimulus. Antioxidants prevent chain of reaction that would result in the production of free radicals. Prolonged usage of steroids as anti-inflammatory agents is unsafe, demanding search for anti-inflammatory compounds with sustainable future. In this study, seeds and leaves of Solanum xanthocarpum were explored in vitro for their anti-inflammatory and antioxidant activity. The ethanolic extract of seeds and leaves of S. xanthocarpum was prepared by maceration. Anti-inflammatory activity of ethanolic extract of seeds (SE) and leaves (LE) was evaluated in terms of percent inhibition of albumin denaturation, membrane stabilization and protease inhibition. The antioxidant activity was estimated by 2,2-diphenyl-1-picrylhydrantiiazyl (DPPH) free radical scavenging assay by exploiting 1,1-diphenyl-2-picrylhydrazine. Successive solvent extraction with maceration of seeds was carried out by using solvents ethanol, ethyl acetate, acetone and water. The ethanolic extracts of seeds and leaves of S. xanthocarpum demonstrates anti-inflammatory and antioxidant activity. The acetones extract exhibited potent antiinflammatory activity than ethyl acetate and aqueous extract. Results presented here suggest that the S. xanthocarpum exhibits anti-inflammatory and antioxidant potentiality.

Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on the ATMEGA328 microcontroller that can be programmed to schedule the on and off operation of an electrical appliance. The appliance is controlled through a relay switch. This timer switch allows you to set both on and off time. That means, you can program when do you want to turn the device on and for how long you want it to be remained on. The maximum time interval that you can set for on and off operation is 99 hours and 59 minutes. The project provides an interactive user interface using a 16×2 character LCD along with 4 push buttons Keywords: Relay, LCD Display (16X2), Clock Unit (DS3231). ULN 2803, ATmega-328
