title: [Chemical constituents from Imperata cylindrica].
abstract: Chemical investigation of Imperata cylindrica led to the isolation of thirteen compounds using various chromatographic techniques. The structure of these compounds were identified as: three phenylpropanoids, 1-(3,4,5-trimethoxyphenyl)-1,2,3-propanetriol ( 1 ), 1-O-p-coumaroylglycerol (2), 4-methoxy-5-methyl coumarin-7-O-beta-D-glucopyranoside (3); four organic acids, 4-hydroxybenzene carboxylic acid(4), 3,4-dihydroxybenzoic acid (5), vanillic acid (6), 3, 4-dihydroxybutyric acid (7); one phenolic compound, salicin (8); and five triterpenes, namely, arundoin (9), cylindrin (10), fernenol (11), simiarenol (12), glutinone (13) by their physicochemical properties and spectral data analysis. Among them, compounds 1-8 were isolated from the genus Imperata for the first time.
