摘要：
Two new acetylated kaempferol glycosides were isolated from the seeds of Camellia semiserrata Chi, their structures were elucidated as kaempferol 3-O-[(3-O-acetyl)-alpha-L-rhamnopyranosyl(1 -> 3)(4-O-acetyl)-alpha-L-rhamnopyranosyl(1 -> 6)-beta-D-glucopyranoside] (1) and kaempferol 3-O-[(2-O-acetyl)-alpha-L-rhamnopyranosyl (1 -> 3)(4-O-acetyl)-alpha-L-rhamnopyranosyl(1 -> 6)-beta-D-gluco-pyranoside] (2) by spectral experiments (including ESI-MS, ID- and 2D-NMR).
