Glycosidic ester and tetra- and hexaglycosides from the fruits of Lycium chinense Miller
Mohammed Ali, Shahnaz Sultana
The fruits of Lycium chinense
(Solanaceae) Miller possess
emmenagogue, diuretic, antipyretic and hepatoprotective
properties and are used to stimulate the immune system, to increase hormonal growth, to improve blood circulation and eye sight
and to cure morning sickness. Phytochemical investigation of an aqueous alcoholic (80%) extract of the fruits gave two new glycosidic aliphatic esters, characterized as 1- linoleoyl-6-linoleneoyl Î²-D- glucopyranoside (1) and arachidyl-O-Î²-D-arabinopyranosyl-(1â†’2)-2â€²-O-Î²-D-arabino- pyranosyl-(1â†’2)-2â€²â€²-O-Î²-D-arabinopyranosyl â€“(1â†’2)-2â€²â€²â€²-O-Î²-D-arabino-pyranoside (2) and one each tetra- and hexaglycosides identified as Î±-D-galactopyranosyl-(2â†’1â€²)-O-Î±-D-xylopyranosyl-(2â€²â†’1â€²â€²)-O-Î±-D-xylopyranosyl-(2â€²â€²â†’1â€²â€²â€²)-Î±-D-xylopyranoside (3) and Î²- D- galactopyranosyl- (6â†’1) â€“O- Î²- D-glucopyranosyl- (6â†’1) â€“ O-Î²- D-glucopyranose- syl - (6â†’1)-Î²- D-glucopyranosyl-(6â†’1)-Î²- D-glucopyranosyl-(6â†’1)-Î²-D-glucopyranoside (4). The structures of these phytoconstituents
have been elucidated on the basis of spectral analysis and chemical reactions.
