Abstract

It is known not only that antifungal compounds such as sparassol, methyl orsellinate (ScI) and methyl-dihydroxy-methoxy-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.

꽃송이버섯(Sparassis crispa)은 배양과정에서 항균물질인 sparassol, methyl orsellinate (ScI)와 methyl-dihydroxy-methoxy-methylbenzoate (ScII) 등의 화합물을 생산하는 것으로 알려져 있으며, 이 중 ScI와 ScII는 sparassol보다 높은 항균활성을 나타내는 것으로 보고되었다. 본 연구에서는 꽃송이버섯의 액체배양 시 균사체가 생산하는 항균 물질인 methy1 orsellinate와 sparassol을 분리하여 NMR과 ESI-MS 분석을 통해 그 구조를 동정하였으며, HPLC 분석을 통해 methy1 orsellinate와 sparassol의 retention time은 각각 15분과 31분임을 확인하였다. S. latifolia의 화합물 생산 양상은 크게 4가지로 대별되며, 균주에 따라 다르게 나타났다. 기주식물과의 상관관계를 분석한 결과, 일본잎갈나무와 잣나무에서 분리된 균주는 서로 다른 생산 양상을 보인 반면, 소나무와 전나무에서 분리된 균주는 동일한 생산 양상을 나타냈다. 균체량과 화합물 생산량과의 상관관계는 나타나지 않았다. Methy1 orsellinate 생산량은 낙엽송에서 분리된 KFRI 645 균주가 0.170 mg/ml로 가장 높았으며, sparassol 생산량은 소나무에서 분리된 KFRI 747 균주가 0.004 mg/ml로 가장 높았다. 이러한 결과를 통해 꽃송이버섯 균주들의 methyl orsellinate와 sparassol의 생산 양상은 기주식물의 종류에 따라 다르다는 사실을 확인하였다.
