Objective: To study the metabolites from the endophytic fungus Penicillium oxalicum of Malus halliana. Method: An endophytic fungus CLP001 was separated from the leaves of M. halliana and identified through its 18SrDNA ITS sequence analysis.The fermentation products were obtained by liquid static culture method
and further isolated and purified by silica gel
Sephadex LH-20 column chromatograghy and preparative HPLC method
and their structures were identified through spectral data and physiochemical properties. Result: The endophytic fungus CLP001 was identified as P. oxalicum CLP001 on basis of their similarity of 99%.Ten compounds were isolated and identified as trilinolein (1)
1
2-dilinolein (2)
1-monolinolein (3)
monacetin (4)
palmitic acid (5)
linoeic acid (6)
ergosterol (7)
1-D-arabinitol-monolinoleate (8)
uracil (9)
and (E)-butenedioic acid (10). Conclusion: Among them
compounds 1 - 4
8 and 10 were isolated for the first time from this genus.
