摘要：The stem juices from Musa × paradisiaca L. banana plants cultivated in their original natural habitat in Vietnam and those cultivated in a greenhouse in the Czech Republic were investigated for the presence of phytochemicals with antidiabetic potency. Respective bioactivities of these phytochemicals were also determined. Sample screening using ultrahigh performance liquid chromatography coupled with tandem high-resolution mass spectrometry (UHPL-HRMS/MS) method showed some differences in the pattern of bioactive compounds, both in terms of their number and concentration. p-Hydroxybenzoic and gallic acids were the predominant analytes found in stem juice from plants grown in Vietnam, while ferulic acid was the major compound found in juice obtained from greenhouse bananas. Despite differences in the occurrence of potentially antidiabetic compounds, both extracts exhibited comparable inhibitory activity against α-glucosidase and α-amylase.
