title: Chemical constituents of Glechoma longituba.
abstract: OBJECTIVE
  To study the chemical constituents of Glechoma longituba (Nakai) Kupr.
  
  
  METHODS
  Manifold chromatography methods were used to separated the chemical constituents, and the chemical structures were determined by spectral analyses.
  
  
  RESULTS
  Nine compounds were isolated from Glechoma longituba and identified, as: glecholone (1), 6R,9R-3-oxo-alpha-ionol (2), S(+)-dehydrovomifoliol (3), vomifoliol (4), corosolic acid (5), quercetin (6), stigmastenol (7), myristic acid (8) and triacontanol (9).
  
  
  CONCLUSIONS
  Compound 1 is a new compound. Compounds 2 - 9 were isolated from this plant for the first time.
