α-Terpineol (1), the main volatile constituent in some traditional Chinese medicines, has been reported to be metabolized to 4R-oleuropeic acid by the larvae of common cutworms. The present study verified that α-terpineol could be converted to 4R-oleuropeic acid (2) and (1S,2R,4R)-p-menthane-1,2,8-triol (3) by Alternaria alternata fermentation. Using shortened fermentation times, 7-hydroxy-α-terpineol
α-松油醇( 1 )是一些中药中的主要挥发性成分,据报道,地老虎幼虫将α-松油醇(1)代谢为4R-油橄榄酸。本研究证实α-萜品醇可以通过链格孢发酵转化为4R-橄榄酸( 2 )和( 1S , 2R , 4R )-p-薄荷烷-1,2,8-三醇( 3 ) 。通过缩短发酵时间,7-羟基-α-萜品醇( 2a )被鉴定为氧化中间体,这与之前研究提出的假设一致。细胞色素 P450 酶也被证实可以催化这种生物转化。这是首次通过微生物发酵生物转化α-萜品醇的研究。
