[Research progress of chromanone derivatives from Calophyllum].

Calophyllum plants have great pharmaceutical value. Some species of this genus are used in folk medicine to treat and cure diseases, such as toothache, rheumatism, diarrhea, chronic ulcers, skin infections, and wounds. The genus is known to be rich in chromanone derivatives, and some of these compounds have antiviral, antifungal, antibacterial, cytotoxic, and other activities. In order to come to a more complete understanding of chromanone derivatives and gain new bioactive constituents from Calophyllum, chemical structures, pharmacological activities, and biogenesis of chromanone derivatives from Calophyllum have been discussed in this review.
