Abstract

Two neolignans, named callislignan A and B together with known C-methyl-flavonoids, a lignan and pentacyclic triterpenoid esters were isolated from the leaves of Callistemon lanceolatus. Their structures were characterized by spectroscopic methods. Callislignan A and B had antibacterial activity against Staphylococcus aureus ATCC25923 and MRSA SK1 with callislignan B having an MIC of 8 mg/mL.Two neolignans, named callislignan A and B together with known C-methyl-flavonoids, a lignan and pentacyclic triterpenoid esters were isolated from the leaves of Callistemon lanceolatus.
