Title: Isolation and identification of chemical constituents from the whole plants of Ajuga decumbens
Abstract: Objective To isolate the constituents from the whole plants of Ajuga decumbens and elucidate their structures.Methods The compounds were isolated by silica gel column,ODS column,semi-preparative HPLC and preparative TLC chromatography and the 1H-NMR,13C-NMR spectroscopic analysis were employed for the structural elucidation.Results Fifteen compounds were isolated from the EtOAc extract of the whole plants of A.decumbens.They are ajugacumbin A(1),ajugacumbin B(2),ajuganipponin B(3),ajugamarin F4(4),ajugarin I(5),ajugamarin A1(6),ajugamarin A1 chlorhydrin(7),apigenin(8),luteolin(9),acacetin(10),methyl caffeate(11),4-hydroxy-4-(3-oxo-1-butenyl)-3,5,5-trimethylcyclohex-2-en-1-one(12),vanillic acid(13),loliolide(14)and(10E,15Z)-9,12,13-trihydroxyoctadeca-10,15-dienoic acid(15).Conclusions Compounds 11 and 12 are obtained from the genus Ajuga for the first time,compounds 7 and 15 are isolated from A.decumbens for the first time.
