The isolation of natural active compounds

Flavonoids are a diverse group of natural compounds extensively studied in various research articles. They are widely distributed in the plant kingdom and exhibit various biological activities, including antioxidant, antiinflammatory, anticancer, antiviral, and antimicrobial effects. The genus Knema Lour., which contains many species in Southeast Asia, has been traditionally used to treat various ailments. The current review aims to provide a comprehensive update on the isolation of flavonoids and other secondary metabolites from the genus Knema Lour. between 1978 and 2022.
