title: New tetraterpene glycosides from the fruits of Lycium chinense.
abstract: Two new compounds lyciumtetraterpenic hexaarabinoside (1) and tetraterpenyl hexaarabinoside (2), along with two known compounds, were isolated from the methanol extract of the fruits of Lycium chinense Miller (Solanaceae), and their structures have been elucidated as 6-(1,1,5-trimethyl-5α-hydroxycyclohexanyl)-6'-(1',1',5'-trimethyl-2'β-hydroxycyclohexanyl)-9,13,9',13'-tetramethyloctadec-7,9,11,13,15,7',9',11',13'-nonene-5α-D-arabinopyranosyl(2a → 1b)-β-D-arabinopyranosyl-(2b → 1c)-β-D-arabinopyranosyl-2'-β-D-arabinopyranosyl-(2d → 1e)-α-D-arabinopyranosyl-(2e → 1f)-α-D-arabinopyranoside (1) and 1(6),11(12),13(14),1'(6'),11'(12'),13'(14')-dodecahydro-β-caroten-4β,4'β-diol-4β-L-arabinopyranosyl-(2a → 1b)-β-L-arabinopyranosyl-(2b → 1c)-β-D-arabinopyranosido-4'β-L-arabinopyranosyl-(2d → 1e)-β-L-arabinopyranosyl-(2e → 1f)-β-D-arabinopyranoside (2) on the basis of spectral data analysis and chemical reactions.
