Abstract Two new flavonol glycosides 3,5,7-trimethoxyflavone-4'-O-[5'''-O-p-coumaroyl-β-D-apiofuranoyl-(1'''→2'')-β-D-glucopyranoside] (1) and 3,5,7-trimethoxyflavone −4'-O-β-D-glucopyranoside (2) were isolated from Selaginella tamariscina. The structures of 1 and 2 were elucidated on the basis of chemical and spectral analysis, including 1D, 2D NMR analyses and HRESIMS spectrometry. Two compounds
摘要 两种新的黄酮醇苷3,5,7-三甲氧基黄酮-4'-O-[5'''-O- p -香豆酰-β -D- apiofuranoyl- (1'''→2'')- β -D-吡喃葡萄糖苷] ( 1 )和3,5,7-三甲氧基黄酮-4'-O- β -D-吡喃葡萄糖苷( 2 )是从柽柳卷柏中分离得到的。基于化学和光谱分析,包括一维、二维核磁共振分析和 HRESIMS 光谱分析,阐明了1和2的结构。通过 MTT 测定评估了两种化合物对 A-375、MCF-7、MDA-MB-231 和 MDA-MB-468 细胞系的细胞毒活性。不幸的是,两种化合物没有表现出细胞毒活性。
