AIM: 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). CONCLUSION: Compound 1 is a new compound. Compounds 2 - 9 were isolated from this plant for the first time.
