Abstract
In order to clarify the chemical constituents of Cistanche deserticola cultured in Tarim desert, a systematically phytochemical investigation was carried out. The chemical constituents were isolated by column chromatography, over silica gel, Sephadex LH-20, MCI gel, ODS and semi-preparative HPLC, and their structures were determined on the basis of MS, NMR spectroscopic data analysis, physicochemical properties and/or comparison with literature data Seventeen compounds were isolated from the 85% ethanol extract of the stems of C. deserticola cultured in Tarim desert. Their structures were identified as salsaside B (1), syringin (2), demethyl syrinyin (3), coniferin (4), (2E,6E)-3,7-dimethyl-8-hydroxyoctadien-1-O-beta-D-glucoside (5), (+)-syringaresinol (6), 2S,3S, 4S-trihydroxypentanoic acid (7), panaxytriol (8), beta-sitosterol-3-O-beta-D-xylopyranoside (9), androsin (10), 3-methyl-but-2-en-1-yl-beta-D-glucopyranoside (11), benzyl-glucopyranoside (12), 4-hydroxybenzyl-beta-D-glucoside (13), nicotinamide (14), p-hydroxybenzoic acid (15), 4-hydroxy-benzeneethanol (16), and galactitol (17). Compounds 3, 6-13 were isolated from this genus for the first time, and compounds 1, 4 and 5 were obtained from this species for the first time.
