The design of this study is to prepare different polarity extracts of H. tuberculatum and to evaluate antioxidant and cytotoxic activities by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and brine shrimp lethality (BSL) methods. The coarse leave samples were extracted with methanol by using a Soxhlet method and the obtained methanol extract was defatted and fractionated by different polarity of solvents with increasing polarity to give hexane, chloroform, ethyl acetate, butanol, and water extracts, respectively. The high antioxidant activity was obtained in the ethyl acetate extract and the lowest was in the methanol extract and the order of activity was ethyl acetate>butanol>water>chloroform>hexane>methanol extract. The cytotoxic activity results showed that the hexane, chloroform and ethyl acetate extracts have killed all the shrimp larvae at the concentration of 500μg/ml. The highest IC50 was found in the chloroform extract and the lowest IC50 was found in the butanol extract and the order of activity was chloroform>ethyl acetate>hexane>water>methanol>butanol e...
