ABSTRACT
Objective To isolate the secondary metabolites of endophytic fungus Aspergillus sp. J218 from Anectochilus roxburhii. Methods Different chromatographic methods, including Sephadex LH-20 and silica gel chromatography as well as HPLC, were used to isolate compounds from the EtOAc fraction of the solid fermentation of J218, and their structures were identified by spectral methods. Results Ten compounds were isolated from the fermentation of J218 and their structures were individually identified as kotanin(1), flavasperone(2), aurasperone B(3), fonsecinone B(4), fonsecinone D(5), ensidol A(6), fonsecinone A(7), fonsecinone C(8), aurasperone A(9), and fonsecinone F(10). Conclusion Most compounds isolated from endophytic fungus Aspergillus sp. J218 in Anectochilus roxburhii were identified as dimeric naphthopyrones. These results suggest that this strain contains rich dimerization synthase, which could provide clues for the further exploration of the rational biosynthesis pathway of dimeric naphthopyrones in this strain.
