Chemical constituents from Glechoma longituba

To study the chemical constituents of Glechoma longituba (Nakai) Kupr.Manifold chromatography methods were used to separated the chemical constituents, and the chemical structures were determined by spectral analyses.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).Compound 1 is a new compound. Compounds 2 - 9 were isolated from this plant for the first time.
