title: [Lignans from stems of Cistanche deserticola cultured in Tarim desert].
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, such as silica gel, Sephadex LH- 20, MCI gel, ODS and semi-preparative HPLC, and their structures were determined on the basis of MS, NMR spectroscopic analysis and/or comparison with literature data. Eleven lignans were isolated from the 85% ethanol extract of the stems of C. deserticola cultured in Tarim desert. Their structures were identified as (+)-syringaresinol-4'-O-β-D-glucopyranoside (1), (+)-isoeucommin A (2), eucommin A (3), (+)-pinoresinol monomethylether β-D-glucoside (4), lariciresinol 4'-O-β-D-glucopyranoside (5), lariciresinol 4-O-β-D-glucopyranoside (6), conicaoside (7), dehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (8), dehydrodiconiferyl alcohol γ'-O-β-D-glucoside (9), citrusin A (10), and alaschanioside A (11). Compounds 1, 3-7, 10 and 11 were isolated from this genus for the first time, and compounds 2, 8 and 9 were obtained from this species for the first time.
