| Abstract | The seed cake is a big by-product after crushing cooking oil from the seeds of Camellia oleifera Abel. Chemical investigation on the seed cake of C. oleifera led to the isolation of two new kaempferol acetylated glycosides (1 and 2). In addition, five kaempferol glycosides (3-7) and their aglycone, kaempferol (8), were also obtained, in addition to gallic acid (9). Their structures were determined by the detailed spectroscopic analysis and acidic hydrolysis. The new compounds were characterised as kaempferol-3-O-[4 ''''-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 6)]-[beta-D-glucopyranosyl-(1 -> 2)]-beta-D-glucopyranoside (1) and kaempferol-3-O-[4 ''''-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 6)]-[beta-D-xylopyranosyl-(1 -> 2)]-beta-D-glucopyranoside (2), respectively. The DPPH radical scavenging activity of all the isolated compounds was described. (C) 2010 Elsevier Ltd. All rights reserved. |
