The study investigated the metabolites of an endophytic fungus
Phoma herbarum
L28 derived from the mangrove plant
Myoporum bontioides
A. Gray. The fungus was fermented in the rice medium. Ten monomeric compounds were isolated and identified as fusarihexin A (
1
),fusarihexin B (
2
),botryosphaerihydrofuran (
3
),
N
1-methyl-2-pyridone-5-carboxamide (
4

6
),4-hydroxyphenylacetic acid (
7
), protocatechuic acid (
8
),thymidine (
