ABSTRACT
AIM To study the chemical constituents of the secondary metabolites of endophytic fungi DL02 from Saposhnikovia divaricata (Turcz.) Schischk.and their biological activities.METHODS The ethyl acetate and methanol extract leavening from S.divaricata was isolated and purified by silica and Sephadex LH-20,then the structures of obtained compounds were identified by physicochemical properties and spectral data.The antifungal and antibacterial activities were determined by the minimum inhibitory concentration method.RESULTS Seven compounds were isolated and identified as β-sitosterol (1),kojic acid (2),stigmasta-7,22-diene-3β,5α,6α-triol (3),uracil (4),allantoin (5),erythritol (6) and adenosine (7).Compound 4 had strong inhibitory effects on pseudomonas aeruginosa with the MIC values of 31.3 μg/mL.CONCLUSION Compounds 2-5 and 7 are isolated from this fungus for the first time.Compounds 4-5 have strong biological activities.
