Two new benzyl derivatives were isolated from ethyl acetate fraction of wild strawberry, var. Lindl. ex Hook.f. The structures of these compounds were elucidated to be 5-(4-hydroxy-3-methoxyphenethyl)-7-methoxy-2H-chromen-3-ol () and 5-(4-hydroxy-3-methoxyphenethyl)-4,7-dimethoxy-2H-chromen-3-ol () based on spectroscopic data through IR, UV, H-NMR, C-NMR along with two dimensional (2D) techniques HMBC, HMQC, and COSY. Both compounds and were studied in tail suspension and forced swim tests for antidepressant like effects. A significant dose dependent antidepressant like effect was observed by causing spontaneous anti-immobility at various test doses upon intraperitoneal administration.
从野生草莓(Fragaria vesca L. var. Lindl. ex Hook.f.)的乙酸乙酯馏分中分离出两种新的苄基衍生物。基于红外光谱(IR)、紫外光谱(UV)、氢核磁共振(H-NMR)、碳核磁共振(C-NMR)以及二维(2D)技术如异核多键相关谱(HMBC)、异核单量子相干谱(HMQC)和同核相关谱(COSY)的光谱数据,确定这些化合物的结构分别为5-(4-羟基-3-甲氧基苯乙基)-7-甲氧基-2H-色烯-3-醇()和5-(4-羟基-3-甲氧基苯乙基)-4,7-二甲氧基-2H-色烯-3-醇()。对化合物和在悬尾试验和强迫游泳试验中进行了抗抑郁样作用研究。腹腔注射后,在不同测试剂量下引起自发的抗不动行为,观察到显著的剂量依赖性抗抑郁样作用。
