abstract: OBJECTIVE
  To study the chemical constituents from the roots of Tinospora sagittata var. yunnanensis.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the constituents. The structures of these compounds were elucidated on the basis of spectral analysis.
  
  
  RESULTS
  Seven compounds were isolated from the plant and their structures were identified as tinophylloloside (1), epitinophylloloside (2), 2-deoxycrustecdysone (3), polypodine B (4) , (+)-5'-methoxyisolariciresinol 3alpha-O-beta-D-glucopyranoside (5), geniposide (6), adenine (7).
  
  
  CONCLUSIONS
  All compounds are isolated from the plant for the first time,and compounds 4, 5, 6 and 7 are isolated firstly from the genus.
