title: [Chemical constituents from Glechoma longituba].
abstract: Fourteen compounds were obtained from Glechoma longituba by the chromatographic methods of silica gel, ODS, Sephadex LH-20 and preparative of HPLC. According to physicochemical properties and spectral data, these compounds were identified as stilbostemin B (1), trilepisiumic acid (2), 3, 4-dihydroxyphenyl ethanol ketone (3), bergeninmonohydrate (4), oresbiusin A (5), norbergenin (6), stilbostemin D (7), ehretioside B (8), ethyl ferulate (9), E-p-hydroxy-cinnamic acid (10), methyl gallate (11), protocatechuic acid (12), 4'-Hydroxyacetophenone (13), and E-3-2,4-dihydroxyphenyl-2-acrylic acid (14). Among them, compounds 1-10, 13 and 14 were isolated from this plant for the first time.
