Chemical Investigation on an Endophytic fungus Gibberella moniliformis JS1055 Derived from a Halophyte Vitex rotundifolia

Chemical investigation of the ethyl acetate extract of Gibberella moniliformis JS1055 endophytic fungus derived from a halophyte, Vitex rotundifolia, led to the isolation of nine compounds including 7-butyl-6,8-dihydroxy-3(R)-pent-11-enylisochroman-1-one (1), 7-butyl-6,8-dihydroxy-3(R)-pentylisochroman-1-one (2), 7-butyl-6,8-dihydroxy-3(R)-pentylisochroman-1-one (3), 5α,8α-epidioxyergosta-6,9(11),22-trien-3-ol (4), ergosterol peroxide (5), tetradecanoic acid (6), 8-O-methylfusarubin (7), nicotinic acid (8) and adenosine (9). They were identified by extensive spectroscopic data analysis including 1D, 2D (¹H-¹H COSY, HSQC, HMBC) NMR, and ESIMS. All the isolates (1
