Abstract: The article aim to research on secondary metabolites of Streptomyces sp.FJS 31-2 from the soil of special habitat Fanjing mountain,not only provide complicated novel compounds for microbial drug but also provide primer for their derivatives synthesis.The secondary metabolites of Streptomyces sp.FJS 31-2 were isolated by means of thin-layer chromatography (TLC),repeated silica column chromatography and RP-silica column chromatography.Its structure was identified on the basis of their mass spectrometry (MS) and nuclear magnetic resonance (NMR) methods.Three III type polyketone compounds obtained from the strain Streptomyces sp.FJS 31-2 and identified as 2-(2′S-hydroxypropyl)-7-hydroxychromone,Aloesone and 3,4-dihydro-3-(2-oxo-propyl)-3,6,8-trihydroxy-1(2H)-naphthalenone combing with MS and NMR.Those compounds were obtained for the first time from Streptomyces genus.

Key words: Streptomyces sp.FJS31-2, secondary metabolites, III type polyketones
