This study assesses whether the distinct altitudinal cline in leaf morphology (decreased leaf width and length with increased altitude) in Tasmanian mountain pepper (Tasmannia lanceolata) is associated with changes in the leaf chemistry of wild populations from different ecological landscapes and altitudes. The presence of distinct pungent drimane sesquiterpenoid chemotypes was identified: subalpine woodland and wet sclerophyll forest chemotypes. Isolation studies and analysis of extracts revealed that wet sclerophyll forest T. lanceolata populations featured polygodial as the principal terpenoid, with profiles similar to the commercial cultivars sampled. In contrast, the subalpine woodland populations contained the drimane sesquiterpenoids 1β-acetoxy-9-deoxyisomuzigadial and 3β-acetoxydrimenin and the conspicuous absence of the pungent principle polygodial.

塔斯马尼亚山椒(Tasmannia lanceolata)中不同的Drimane化学型:与垂直线相关的有毒叶片植物化学成分的差异。
这项研究评估了塔斯马尼亚山胡椒(Tasmannia lanceolata)叶片形态上独特的海拔变化(叶宽度和长度随高度增加而降低)是否与来自不同生态景观和高度的野生种群的叶片化学变化有关。确定了独特的刺激性drimane倍半萜类化学型的存在:亚高山林地和湿性硬叶林化学型。提取物的分离研究和分析表明,湿叶硬叶林轮叶轮虫种群以多角形为主要类萜,其特征与所采样的商业品种相似。相比之下,
