Their structures, including

Keywords: agarwood; Aquilaria sinensis; SAR studies; sesquiterpenoids; Introduction Agarwood is the resinous wood of the Aquilaria species of the Thymelaeaceae family [1]. It is a precious traditional Chinese medicinal material and a kind of natural

• deep insight into novel molecules with effective bioactivities from agarwood. Therefore, the continued study of Aquilaria sinensis has led to the isolation of ten sesquiterpenoids, including five new eudesmane-type sesquiterpenoids (Figure 1). Herein, we describe the isolation, structural elucidation
