In phytochemical studies of Fritillaria camtschatcensis bulbs, two phenolic glycosides [(2S)-1-O-p-coumaroyl-3-O-β-D-glucopyranosylglycerol (regaloside A) and 3,6'-O-diferuloylsucrose] and two steroidal alkaloids [solanidine 3-O-[α-L-rhamnopyranosyl(1→2)][β-D-glucopyranosyl(1→4)]-β-D-glucopyranoside and 2β,3α,6β-trihydroxy-5α-jervanin-12-ene (kuroyurinidine)] were isolated. Kuroyurinidine is the first example of the C-nor-D-homo steroidal alkaloid from F. camtschatcensis. Regaloside A was obtained in good yield from F. camtschatcensis. Solanidine glycoside was isolated from the unhydrolysed methanolic bulb extract of F. camtschatcensis for the first time. The structure of the novel compound kuroyurinidine was determined mainly by two-dimensional correlated spectroscopies and stereospecific spin-coupling constants.
