Abstract:
Taking berberine (BBR) as an example, to study whether the supramolecular hydrogel formed by berberine and lotus root starch (Nelumbo nucifera Gaertn; LRS), a natural polysaccharide, affects the inhibition to Staphylococcus aureus and the ability of biofilm clearance. The chemical structure and rheological properties of BBR@LRS gel were characterized by infrared spectroscopy and rheometer. The in vitro release of supramolecular hydrogel was observed at pH = 1.2 and pH = 7.4. Broth dilution method and biofilm clearence experiment were used to observe the bacteriostasis and biofilm clearance respectively. Cytotoxicity test and in vitro hemolysis test were used to evaluate the biosafety preliminarily. The results showed that the LRS polysaccharide hydrogel could encapsulate BBR, and there was an interaction between them. The BBR@LRS gel had good rheological properties and biosafety, and played a role in solubility enhancement and slow release of BBR, which was stronger than BBR in inhibiting the growth of Staphylococcus aureus and clearing biofilm. This study provides reference for the effect of natural polysaccharide supramolecular hydrogels on biological functions of active components of traditional Chinese medicine.
