In order to study the secondary metabolites from the coralderived symbiotic fungi NG15-3 of South China Sea
the compounds were isolated by silica gel column chromatography and HPLC. Their structures were identified on the basis of spectral data and physical constant comparison. Four anthraquinones and six nitrogen compounds were isolated as preechinulin (1)
emodin (2)
1-O-methyl emodin(3)
physcion (4)
carviolin (5)
cyclo-(Phe-Gly) (6)
cyclo-(Gly-Pro) (7)
3H-imidazole-4-carboxylic acid (8)
2-methyl-3H-imidazole-4-carboxylic acid (9) and 1H-pyrrole-2-carboxylic acid (10). All the secondary metabolites were firstly acquired from the coralderived symbiotic fungi NG-15-3 of South China Sea and compound 1 was a precursors of the monodehydro-2
