Objective: To study the chemical constituents from the branches and leaves of Sabina gaussenii. Method: Silica gel

Sephadex LH-20

RP-18

MCI-gel column chromatography

semi-preparative HPLC and other means were used to isolate an purify the constituents

the structures of the compounds were identified by physicochemical properties and spectral data. Result: Seven compounds were obtained from the ethyl acetate fraction of ethanol extract in the branches and leaves of S. gaussenii and identified as(7S
