説明
<jats:title>Abstract</jats:title><jats:p>Two new eremophilane‐type sesquiterpenoids, fusumaols A (<jats:bold>1</jats:bold>) and B (<jats:bold>2</jats:bold>), were isolated from the stem‐leafy liverwort, <jats:italic>Bazzania japonica</jats:italic> collected in Mori‐Machi, Shizuoka, Japan. Their structures were established using extensive spectroscopic (IR, MS, and 2D NMR) data, and the absolute configuration of <jats:bold>1</jats:bold> was determined by the modified Mosher's method. This is the first time eremophilanes have been discovered in the liverwort genus <jats:italic>Bazzania</jats:italic>. Compounds <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> were evaluated for their repellent activity against the adult population of the rice weevil <jats:italic>Sitophilus zeamais</jats:italic> using the modified filter paper impregnation method. Both sesquiterpenoids showed moderate repellent activities.</jats:p>
