n-BuOH extract from the herb of Solanum lyratum Thunb. (Solanaceae) was purified by various chromatographic methods, which led to the isolation of seven undescribed alkaloids ((−)-(7′S)–N-feruloyltyramine A, (+)-(7′R)-N-feruloyltyramine A, (+)-(7′S)–N-solanamide A, (−)-(7′R)-N-solanamide A, 7′S-perillascens, solanpyrrole A, and (Z)-asmurratetra A) and 13 known alkaloids, including four pairs of enantiomers
来自Solanum lyratum Thunb草本植物的正丁醇提取物。(Solanaceae) 通过各种色谱方法纯化,从而分离出七种未描述的生物碱 ((−)-(7' S )– N -阿魏酰胺 A,(+)-(7' R )- N -阿魏酰胺 A, (+)-(7' S )– N-茄酰胺 A, (−)-(7' R )- N-茄酰胺 A, 7' S -紫苏, 茄吡咯 A, ( Z)-asmurratetra A) 和 13 种已知生物碱,包括四对对映体。应用广泛的光谱数据和电子圆二色性 (ECD) 计算来确定未描述化合物的结构。在体外生物活性测定中,(−)-(7′ S )– N -阿魏酰胺 A 和 (+)-(7′ R )- N -阿魏酰胺 A 对 SH-SY5Y 细胞损伤具有显着的神经保护作用,存活率为在 50 μM 时分别为 75.98% 和 76.61%。此外,(−)-(7′ S )– N -阿魏酰胺
