It is known not only that antifungal compounds such as sparassol, methyl orsellinate (ScI) and methyl-dihydroxymethoxy-methylbenzoate (ScII) were produced during submerged culture from Sparassis crispa, but also that ScI and ScII were appeared higher antifungal activity than sparassol. The aim of this study, antifungal compounds of Sparassis latifolia were purified from mycelial culture media and identified by using NMR and ESI-MS. Based on HPLC analysis, methyl orsellinate and sparassol were detected at 15 min and 31 min of retention time, respectively. The compounds derived from S. latifolia were classified into four production patterns according to their strains. The strains originated from host plant Larix kaempferi and Pinus koraiensis showed different patterns of compound production, whereas the strains originated from host plant P. densiflora and Abies holophylla showed almost same patterns. There was no correlation between mycelial biomass and compound production. KFRI 645 strain from L. kaempferi exhibited higher methyl orsellinate production (0.170 mg/ml). Sparassol was produced by KFRI 747 from P. densiflora (0.004 mg/ml). Thus, our result revealed the new fact that methyl orsellinate and sparassol have different patterns according to the strains originated from different host plants.
