Abstract
Musa balbisiana corm is a potential source of bioactive phytochemicals, including polyphenols and saponins. This study optimized microwave-assisted extraction (MAE) of polyphenol- and saponin-rich extracts using response surface methodology with a Box-Behnken design. Under the validated optimum conditions (70% methanol, 270 W, 4 s/min irradiation cycle, and a fixed extraction time of 40 min), TPC and TSC reached 71.35 ± 0.51 mg GAE/g DM and 60.68 ± 1.23 mg/g DM, respectively. FT-IR and Raman spectra showed vibrational features consistent with hydroxylated aromatic compounds and glycoside-containing constituents; these spectra are regarded as supportive rather than compound-specific evidence for saponins. A purified fraction was tentatively assigned as quercetin based on close agreement of its ¹H and ¹³C NMR data with published reference data. Definitive confirmation would require orthogonal evidence such as HRMS/LC-MS and/or 2D NMR.
