Abstract

Two novel compounds SSC1 and SSC2 were isolated from culture broth produced from the strain of Stereum hirsutum by using of YM broth. They were isolated through HP-20 column chromatography, silica gel column chromatography and preparative HPLC, successively. The molecular formulas of SSC1 and SSC2. were determined as C$\sub$15/H$\sub$22/O$_3$ by high resolution EI -mass. The chemical structures of SSC1 and SSC2 were determined as sesquiterpenoid compounds by spectroscopic analysis of UV, IR, $^1$H NMR, $\^$13/C NMR, DEPT, HMQC and HMBC spectrum.
