Innovative solutions are needed as a pre-requisite to address the challenges in bio-batteries where electrolytic materials play a major role in its performance. Therefore, the current investigation had focused to study the banana pith applicability as an electrolyte with an intention to find the best local banana variety among three selected varieties [Musa AAB Group (Plantain Subgroup) \'alukesel′, Musa AAB Group (Mysore Subgroup) \'ambul′ and Musa AAA Group (Cavendish Subgroup) \'ambun′]. This was conducted by qualitative and quantitative phytochemical analysis on pith of 3 banana varieties. The trunks of three banana varieties were chopped using an electric blender and were kept on a hot plate set at 120 oC for 30 minutes which were used for phytochemical screening and thin layer chromatography (TLC) afterwards. The presence of saponins, tannins, flavonoids and phenolics were revealed from the preliminary phytochemical screening while terpenoids, alkaloids and steroids were absent in all 3 varieties. Among the three varieties ambun variety exhibited highest amount of total phenol (2.27 ± 0.09 mg gallic acid equivalents/g of extract) and total flavonoid (1.50 ± 0.04 mg quercetin equivalents/g of extract) contents. Although the pith of ambun headed among the selected varieties from its galvanic battery performance indicators in an acidic medium, the secondary metabolites do not seem to facilitate the efficacy of the bio-battery with a profound relationship. Hence, additional research work is required to elucidate the possible mechanism of action of these found secondary metabolites with further quantification methods.
