Highlights
- Temperature showed a large influence on the components of the
bioactives of Strobilanthes cusia .
- β-Glucosidase activity was the key point for the change of components
of bioactives.
- The bioactives consisted mainly of indican, indoxyl, indigo and
indirubin.
- Indoxyl exhibited the highest antimicrobial ability among the
components.
- Indoxyl decreased the formation of extracellular matrices and altered
the intracellular redox status of Staphylococcus aureus .
