Arch Pharm Res. 2008 May;31(5):573-8. | Heterocyclic compounds from Chrysanthemum coronarium L. and their inhibitory activity on hACAT-1, hACAT-2, and LDL-oxidation.[Pubmed: 18481011] | METHODS AND RESULTS:
The aerial parts of Chrysanthemum coronarium L. were extracted with MeOH, and the concentrated extract was partitioned using EtOAc, n-BuOH, and H(2)O, successively. Repeated column chromatography of the EtOAc and n-BuOH fractions gave a new heterocycle, 5,5'-dibuthoxy-2,2'-bifuran (1) along with five known compounds: methyl trans-ferulate (2), prunasin (3), sambunigrin (4), Pterolactam (5), and adenosine (6), which were identified by several spectroscopic methods including NMR and MS.
CONCLUSIONS:
This paper is the first report on the isolation of these compounds from C. coronarium L. The IC(50) values of compound 1 for human Acyl-CoA:cholesterol acyltransferase (hACAT)-1 and hACAT-2 were 0.16 mM and 0.19 mM, respectively. Compound 2 inhibited low-density lipoprotein (LDL) oxidation with an IC(50) value of 7.7 microM. |
