Eleven phenolic compounds including four new ones, (R)-4-(1-methoxypropyl)phenol (1), (S)-3-(4-hydroxy-3-methoxyphenyl)propane-1,2-diyldiacetate (2), (R)-3-(4-hydroxy-3-methoxyphenyl)propane-1,2-diyldiacetate (3) and 3′-demethoxycrataegusanoid E (4), were isolated from the fruits of Alpinia galanga. The structures of new compounds were elucidated on the basis of extensive spectroscopic data (1D and
十一种酚类化合物,包括四种新化合物,( R )-4-(1-甲氧基丙基)苯酚 ( 1 ), ( S )-3-(4-hydroxy-3-methoxyphenyl)propane-1,2-diyldiacetate ( 2 ), ( R )-3-(4-hydroxy-3-methoxyphenyl)propane-1,2-diyldiyldiacetate ( 3 ) 和 3'-demethoxycrataegusanoid E ( 4 ) 是从高良姜的果实中分离出来的。基于广泛的光谱数据(一维和二维核磁共振、[ α ] D、HRESIMS、紫外和红外)阐明了新化合物的结构。检测了所有分离株对 PTP1B 和α-的抗糖尿病效力糖苷酶和胰高血糖素样肽-1 (GLP-1) 的促进作用。化合物4对PTP1B有显着抑制作用,IC 50值为58.4 μM,化合物6具有α-糖苷酶抑制活性,IC 50值为97
