The isolation and structure elucidation of antifungal constituents of the steam-distilled essential oil fraction of Artemisia dracunculus are described. Antifungal activities of 5-phenyl-1,3-pentadiyne and capillarin against Colletrotichum fragariae, Colletrotichum gloeosporioides, and Colletrotichum acutatum are reported for the first time. The relative abundance of 5-phenyl-1,3-pentadiyne is about 11% of the steam-distilled oil, as determined by GC-MS. Methyleugenol was also isolated and identified as an antifungal constituent of the oil.
描述了龙蒿水蒸气蒸馏精油馏分中抗真菌成分的分离和结构解析。首次报道了5-苯基-1,3-戊二炔和毛蒿素对草莓炭疽病菌、胶孢炭疽病菌和尖孢炭疽病菌的抗真菌活性。通过气相色谱-质谱联用(GC-MS)测定,5-苯基-1,3-戊二炔的相对含量约为水蒸气蒸馏油的11%。还分离并鉴定了甲基丁香酚作为该油的一种抗真菌成分。
