Three new flavone C-glycosides with the substitution of the unusual acyl, 2''-O-veratroylisoswertisin (1), 3''-O-2-methylbutyrylisoswertiajaponin (2), and 3''-O-2-methylbutyrylvitexin (3), together with the known compounds of 2''-O-2-methylbutyrylisoswertisin (4), 3''-O-2-methylbutyrylisoswertisin (5), and trollisin I (6) were isolated from the antibacterial fraction of the aqueous extract of the flowers of Trollius chinensis. The structural elucidations of these compounds were carried out by a detailed analysis of the NMR and MS spectra.
从中国金莲花花朵水提取物的抗菌部分中分离出三种新的黄酮碳苷,它们带有不寻常的酰基取代基,即2''-O-藜芦酰异荭草苷(1)、3''-O-2-甲基丁酰异荭草日本苷(2)和3''-O-2-甲基丁酰牡荆素(3),以及已知化合物2''-O-2-甲基丁酰异荭草苷(4)、3''-O-2-甲基丁酰异荭草苷(5)和金莲花素I(6)。通过对核磁共振(NMR)和质谱(MS)谱图的详细分析对这些化合物进行了结构解析。
