    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 comparison with literature data. Four compounds were isolated from the 85% ethanol extract of the stems of C. cultured in Tarim desert. Their structures were identified as cis-tubuloside (1), cis-cistanoside (2), cis-cistanoside J (3), and cis-isocistanoside C(4). Compounds 1-4 were four new cis-phenylethanoid glycosides. Herein, we firstly report the ¹H, ¹³C-NMR data of the new compounds(1-4) for the first time. This study will provide the scientific evidence for comprehensively analyzing the chemical constituents of C. deserticola cultured in Tarim desert.
