OBJECTIVETo study the chemical constituents from the roots of Rehmannia glutinosa.
METHODThe compounds were isolated by various chromatographic methods and identified by spectroscopic analysis.
RESULTTwelve compounds were isolated and their structures were identified as 5-hydroxymethyl-pyrrole-2-carbaldehyde (1), 5-hydroxymethyl furfural (2), tyrosol (3), 5,6-dihydroxy-beta-ionone (4), 6-O-E-feruloyl ajugol (5), acteoside (6), leucosceptoside A (7), martynoside (8), isomartynoside (9), purpureaside C (10), jionoside A1 (11), and jionoside B1 (12).
CONCLUSIONCompounds 1, 3 and 9 were isolated from the genus Rehmannia for the first time.
