Two new phenylpropanoids and a new dihydrostilbene, along with five analogues, were isolated from the flower buds of Magnolia biondii Pamp. Their structures and absolute configurations were elucidated through extensive spectroscopic analyses and comparison with literature data. Additionally, the compounds were evaluated for their acetylcholinesterase inhibitory activities in vitro.
Two new phenylpropanoids, named (2'R*,3'R*)-2',3'-dihydroxy-4'-methoxy-caffeoyl butyrate (1), 9-acetoxy syringin (2), and a new dihydrostilbene, named (8'R)-4',5-dihydroxy-4,8'-dimethoxy-2-hydroxyethyl diphenylethane (3), together with five analogues (4-8), were isolated from the flower buds of Magnolia biondii Pamp. Their structures were elucidated by extensive spectroscopic analyses and comparison with literature data. The absolute configurations were deduced by comparison of experimental and calculated gauge-independent atomic orbital (GIAO) 1 D NMR data. Moreover, the isolated compounds (1-8) were evaluated in vitro for their acetylcholinesterase (AChE) inhibitory activities.
