ABSTRACT
Objective To study the secondary metabolites of endophytic fungus Fusarium lactis in Dendrobium huoshanense. Methods Compounds were isolated from the EtOAc extract by chromatography technology and their structures were elucidated on the basis of comprehensive spectroscopic analysis. Results Twenty-one compounds were isolated and identified as N-phenethylacetamide (1), 1H-indole-3-carbaldehyde (2), thymidine (3), uracil (4), lignoren (5), uridine (6), hexahydrate (7), adenosine (8), cyclo-glycine-(L)-proline (9), cyclo (D)-proline-(L)-phenylalanine (10), cyclo (L)-proline-(L)-phenylalanine (11), 2-pyrrolidinone (12), N-methyl-2-pyrolidinone (13), cyclo-(L)-4-OH-proline-(L)-phenylalanine (14), brevianamide F (15), 3-methyl- piperazine-2,5-dione (16), 7,8-dimethylbenzo[g]pteridine-2,4 (1H,3H)-dione (17), cyclo (L)-tyrosine-(L)-phenylalanine (18), beer sterols (19), daidzein (20), and erythritol (21). Conclusion All compounds are isolated from Fusarium lactis for the first time.
