- 論文の詳細を見る
Four oleanane-type triterpene saponins named luperosides I, J, K and L were isolated as their methyl esters from the MeOH extract of the herb of Luffa operculata COGN., and their structures were elucidated on the basis of chemical and spectral evidence. Luperosides I and J are 3-O-[β-D-galactopyranosyl-(1→2)-[α-L-arabinopyranosyl-(1→3)]-β-D-glucopyranosyluronic acid]-28-O-[β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→3)]-β-D-quinovopyranosyl] gypsogenin (I) and 3-O-[β-D-galactopyranosyl-(1→2)-[α-L-arabinopyranosyl-(1→3)]-β-D-glucopyranosyluronic acid]-28-O-[β-D-xylopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→3)]-β-D-quinovopyranosyl] gypsogenin (J), respectively. Luperosides K and L are quillaic acid glycosides corresponding to luperosides I and J, respectively.
