Phytochemical screening, antioxidant and antibacterial activities of citrus hystrix leaves / Syafiqah Alya Samlin
Phytochemical screenmg, antioxidant and antibacterial activities, Citrus hystrix leaves have been studied. Different polarities of extraction solvents are used which are hexane, chloroform and ethanol. Ethanol crude gave the highest percentage yield (3.14%) followed by chloroform and hexane. Seconda...
