Xanthones from roots of Calophyllum thwaitesii and their bioactivity.
Extracts from three Calophyllum species endemic to Sri Lanka were tested for antifungal and antioxidant activities. Of them, only the root methanol extract of Calophyllum thwaitesii showed activity, and the active extract on activity guided fractionation yielded four antifungal active and three inactive xanthones. Antifungal active xanthones were identified as 1,6-dihydroxy-5-methoxyxanthone, 1...
