[Study on the chemical constituents of Mitragyna rotundifolia].
Twelve compounds were isolated from the EtOAc-soluble and ButOH-soluble portions of the EtOH extract from the bark of Mitragyna rotundifolia. These compounds were identified by their spectral data as dauricine (1), 3,4-dihydroxybezoic acid (2), beta-sitosterol (3), scopleton (4),3,4,5-trimethyoxyphenol-1-glucopyranoside (5), taraxerol (6), 4-hydroxy-3-methyloxybenzoic acid (7), 3-hydroxy-4-methyloxybenzoic acid (8), caffeic acid (9), gambirine (10), gambireine (11),1,1-dimetheyl-2-acetl-diethyl ether (12), respectively. All compounds were isolated from this genus for the first time.
