Chemical investigation of Anisothecium spirale (Mitt.) Broth. (Family Dicranaceae), an epiphytic moss from the Darjeeling district hill region of the Eastern Himalayas was performed for the first time. Analysis of neutral lipid and phospholipid classes as well as their respective fatty acids revealed the presence of a significantly high content of octadeca-6-yn-9,12,15-trienoic acid, an acetylenic fatty acid commonly known as dicranin. Dicranin and a less abundant acetylenic fatty acid were detected in neutral lipids. The unique nature of the fatty acid signature supports the view of considering dicranin as chemotaxonomic marker for Dicranaceae members.
首次对采自东喜马拉雅大吉岭地区山区的附生苔藓螺旋异蒴藓（米氏）布罗特（曲尾藓科）进行了化学研究。对中性脂质和磷脂类别及其各自的脂肪酸进行分析后发现，其中含有含量显著较高的十八碳-6-炔-9,12,15-三烯酸，这是一种通常被称为异蒴藓素的炔属脂肪酸。在中性脂质中检测到了异蒴藓素和一种含量较少的炔属脂肪酸。这种独特的脂肪酸特征支持将异蒴藓素视为曲尾藓科成员化学分类学标记的观点。
