Objective: The secondary metabolites of the fungus ZZF13 isolated from the leaves of the mangrove sample Kandelia candel in Zhanjiang and Guignardia sp. 4382 isolated from bark of Kandelia candel (endophyte) of Mai Po, Hong Kong were studied.
Methods: The compounds were isolated by siliga gel, and their structures were identified by IR, MS and NMR.
Results: Four compounds were isolated from the culture of this strain. Their structures were identified as Bacillpsporin C (1), 5-carboxymellein (2), 5-methylmellein (3) and 1-(2,6-dihydroxyphenyl) butanone (4).
Conclusion: The compounds 2 - 4 are isolated from the Guignardia sp. of Marine fungi for the first time.
