Two new acetylated kaempferol glycosides were isolated from the seeds of Camellia semiserrata Chi, their structures were elucidated as kaempferol-3-O-[(3-0-acetyl)-α-L-rharnnopyranosyl(1→3)(4-O-acetyl)-α-rhamnopyranosyl(l→6)-β-D-gluco-pyranoside] (1) and kaempferol-3-O-[(2-O-acetyl)-α-L-rhamnopyranosyl (1→3)(4-O-acetyl)-α-L-rhamnopyranosyl(l→6)-β-d-gluco-pyranoside] (2) by spectral experiments (including ESI-MS, ID- and 2D-NMR).
