Introduction: The phytochemicals in medicinal plants are defined as bioactive non nutrient plant compounds in fruits, vegetables and grains that have been linked to reducing the risk of major chronic diseases. The medicinal plant are promising to have such have effective medicinal property due to presence of phytochemical compounds like alkaloids, tannins, flavonoids and phenolic compounds. The present study aimed to find the phytochemicals present in hexane and ethyl acetate extracts of Justicia tranqubarieansis and Bauhinia racemosa and also find out the antioxidant property of these plant extracts. Methods: Phytochemicals present in the hexane and ethyl acetate extract of Justicia tranqubarieansis and Bauhinia racemosa were identified by chemical methods. Antioxidant property was done by DPPH free radical scavenging method. Results: In Justicia tranqubarieansis, hexane extract showed positive for flavonoids, alkaloids and coumarins. Ethyl acetate extract showed positive for flavonoids, alkaloids, cardiac glycosides, terpenoids, coumarins and steroids. Hexane extract of Bauhinia racemosa showed positive for flavonoids, alkaloids, quinines, cardiac glycosides, terpenoids and coumarins. Ethyl acetate extract showed positive for flavonoids, alkaloids, cardiac glycosides, terpenoids, coumarins and steroids. Ethyl acetate showed better extraction of phytochemicals than Hexane. Hexane and ethyl acetate extracts of Justicia tranqubarieansis exhibited 66% and 90% respectively of free radical scavenging activity at a concentration of 150µg. Extracts of Bauhinia racemosa showed less antioxidant activity. Conclusion: This study suggests that the Justicia tranqubarieansis extracts have good antioxidant property, which might be helpful in preventing of slowing they progress of diseases involved as result of oxidative stress.
