Abstract:

Three known compounds were isolated from the endophytic fungus Trichoderma sp. Xy24 from a mangrove plant Xylocarpus granatum by using various column chromatography techniques. Their structures were identified as harzianone (1), trichoacorenol (2), and trichodimerol (3) by extensive spectroscopic analysis. Among them, 1 was a harziane diterpene, 2 wasa sesquiterpene alcohol, and 3 was a polyketide with a completely symmetric configuration. Compound 3 exhibited medium inhibitory activity with an IC50 value of 74.6 μMusing a NA (H7N9)/MUNANA model.
