A new disaccharoside (2) together with a known disaccharose (1) was isolated from the ethanol extract of Camptosorus sibiricus Rupr. By means of chemical (hydrolysis) and spectroscopic methods (IR, 1D and 2D NMR, ESI-MS), the structures were established as beta-D-glucopyranosyl (1 --> 2)-beta-D-glucopyranoside (1) and Octane-1-en-3-ol-3-O-beta-D-glucopyranosyl (1 --> 2)-beta-D-glucopyranoside (2) respectively. Compounds 1 and 2 were isolated from this genus first and their anti-tumour activities were tested against two human tumour cell lines using MTT method.
