Abstract
The tetracyclic sesquiterpene, ishwarane, was isolated from the leaves of the representative species of the genus Hortonia, H. angustifolia, H. floribunda and H. ovalifolia collected in Sri Lanka. The complete 2D NMR assignments are reported. Ishwarane exhibited antifungal activity against Cladosporium cladosporioides.
Keywords: Antifungal activity, Hortonia, ishwarane, 2D NMR assignments, Sri Lanka.
