Galloylated flavonol rhamnosides from the leaves of Calliandra tergemina with antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA)

Galloylated flavonol rhamnosides 1-3, together with five known flavonol rhamnosides, were isolated from a leaf extract of Calliandra tergemina. All metabolites were analysed for their potential anti-MRSA activities.
