Chemical Constituents from the Fermentation Broth of Streptomyces sp.(YIM69228)

The chemical constituents from the fermentation broth of Streptomyces sp.YIM69228 were studied.Ten compounds were isolated from it,and their structures were determined by spectrum analysis as(S)-2-hydroxy-3-(4-methoxyphenyl) propanoic acid(1),Isoscopoletin(2),N-phenethylacetamide(3),Cinnamic acid(4),4-methoxy-4-oxobutanoic acid(5),3,4-dihydroxy benzoic acid(6),Trehalose(7),Vomifoliol(8),Citroside A(9),Benzyl-β-D-xylopyranosyl-(1″-6′)-β-D-glucopyranoside(10).It was the first time to determine the configuration of natural compound 1.Compound 8-10 were isolated from the genus Streptomyces for the first time.
