Three new eudesmane-type sesquiterpenoids, compounds 1-3, and eight known constituents, including mucrolidin (4), 1beta,4beta,7alpha-trihydroxyeudesmane (5), 1beta,4beta,6beta,11-tetrahydroxyeudesmane (6), oplodiol (7), bullatantriol (8), acetylbullatantriol (9), homalomenol (10), and maristeminol (11), were isolated from the aerial parts of Homalomena occulta. Their structures were determined by interpretation of spectroscopic and mass-spectrometric data, and their antimicrobial activities toward six different bacterial strains were tested. Most of the compounds showed weak antibacterial activities in an agar-diffusion assay.
从隐棒花的地上部分分离出了三种新的桉叶烷型倍半萜化合物1 - 3，以及八种已知成分，包括粘劳狄醇（4）、1β,4β,7α - 三羟基桉叶烷（5）、1β,4β,6β,11 - 四羟基桉叶烷（6）、蛇麻脂醇（7）、密花八角莲三醇（8）、乙酰密花八角莲三醇（9）、细柄芋醇（10）和海芋醇（11）。通过光谱和质谱数据的解析确定了它们的结构，并测试了它们对六种不同细菌菌株的抗菌活性。在琼脂扩散试验中，大多数化合物显示出较弱的抗菌活性。
