Objective To research the chemical constituents of the n-butyl alcohol part of Gueldenstaedtia stenophylla Bunge . Method The n-butyl alcohol fraction of Gueldenstaedtia stenophylla Bunge was separated and purified by silica gel ,ODS and poly amide column chromatography .The physicochemical property and spectral analysis were used to analyze the compound structures . Results Four compounds were obtained ,and they were identified as β-sitosterol (1) ,quercetin-3-O-β-D-glucoside (2) ,β-sitosterol glucoside (3) ,and soyabean saponin B-3-O-[α-D-rhamnose (1→2)-β-D-glucose (1→2)-β-D-glucuronic] (4) .Conclusion Com-pound 2 ,4 were flavanoid and triterpenoid saponin .These compounds were isolated for the first time from Gueldenstaedtia steno-phylla Bunge .
