(+)-3α-Hydroxylupanine, a new alkaloid from Ammopiptanthus mongolicus (MAXIM.) CHENG F.

Abstract

From leaves of Ammopiptanthus mongolicus (MAXIM.) CHENG F. were isolated (+)-3α-hydroxylupanine (I), (1R)-3-O-methyl[1,2,4/3,5,6]-inositol (V), salicylic acid, (-)-piptanthine (III), 7-hydroxy-4'-methoxyisoflavone (VIII), 7,3'-dihydroxy-4'-methoxyisoflavone (X) and 4'-methoxyisoflavone-7-β-D-glucopyranoside (IX). All the compounds were characterized on the basis of spectral data; the first three compounds were isolated from this material for the first time.
