BACKGROUND Pseudostem and rhizome are the significant bio‐waste generated (43.48%) from the banana plant post fruit harvest, which are usually left in the plantation or incinerated and wasted. Amounts used in production for consumption are negligible. However, the material has an important part to play in indigenous systems of medicine. Based on the huge volume of bio‐waste generated and its traditional medicinal use, it is worth exploiting it as a source of natural bioactive compounds. In the current study, sequential extracts from banana pseudostem ( BPS ) and rhizome ( BR ), and isolated compounds including chlorogenic acid, 4‐epicyclomusalenone and cycloeucalenol acetate, were tested for their antimicrobial activity, antiplatelet aggregation and cytotoxicity. RESULTS Isolated compounds and crude extracts exhibited strong antimicrobial activity against a wide range of bacterial and fungal strains, platelet aggregation induced by collagen and cytotoxicity towards human liver cancer ( HepG2 ) cells. CONCLUSION Banana plant bio‐waste, pseudostem and rhizome may serve as a potential source of multifunctional bioactive compounds and functional ingredient in food and other allied industries. © 2015 Society of Chemical Industry
