Chemical constituents of Glechoma longituba

AimTo 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. ResultsNine compounds were isolated from Glechoma longituba and identified, as: glecholone (1), 6R,9R-3-oxo-α-ionol (2), S(+)-dehydrovomifoliol (3), vomifoliol (4), corosolic acid (5), quercetin (6), stigmastenol (7), myristic acid (8) and triacontanol (9). ConclusionCompound 1 is a new compound. Compounds 2-9 were isolated from this plant for the first time.
