We investigated the microbial conversion of curcumin (1) using endophytic fungi associated with the rhizome of Curcuma longa (Zingiberaceae). We found that Diaporthe sp., an endophytic filamentous fungus, converts curcumin (1) into four colorless derivatives, namely (3R,5R)-tetrahydrocurcumin (2), a novel (3R,5S)-hexahydrocurcumin (3) named neohexahydrocurcumin, (3S,5S)-octahydrocurcumin (4) and meso-octahydrocurcumin (5).
我们利用与姜黄(姜科)根茎相关的内生真菌研究了姜黄素(1)的微生物转化。我们发现内生丝状真菌 Diaporthe sp.能将姜黄素(1)转化为四种无色衍生物,即(3R,5R)-四氢姜黄素(2)、一种名为新六氢姜黄素的新型(3R,5S)-六氢姜黄素(3)、(3S,5S)-八氢姜黄素(4)和中八氢姜黄素(5)。
