The chemical components of Coreopsis tinctoria Nutt. and their antioxidant, antidiabetic and antibacterial activities.[Pubmed:30499349]
Nat Prod Res. 2020 Jun;34(12):1772-1776.
Seventeen compounds were isolated from the capitula of Coreopsis tinctoria Nutt. with various column chromatographic methods and semi-preparative HPLC. Their structures were identified by the spectroscopic data and comparison with literatures as 2'-hydroxy-4,4'-dimethoxy-chalcone; (1), isoliquiritigenin (2), eriodictyol (3), naringenin (4), maritimetin (5), butin (6), taxifolin (7), luteolin (8), 7,3',4'-trihydroxyflavone (9), 8,3',4'-trihydroxyflavone-7-O-beta-d-glucoside (10), quercetin (11), quercetagitin-7-O-beta-d-glucoside (12), quercetin-7-O-beta-d-glucoside (13), 3,4-dihydroxybenzoic acid (14), caffeic acid (15), Coreoside B (16), and myo-inositol (17). Compounds 1, 4, 9, 10 and 17 were isolated from C. tinctoria Nutt. for the first time. Compounds 7 and 12 possessed the highest antioxidant activity (IC(50) = 64.37 and 32.86 microg/ml, respectively) among the tested compounds (IC(50) value of positive control was 5.34 microg/ml). Compound 7 exhibited potent PTP1B enzymatic inhibition with an IC(50) value of 7.73 mug/ml (IC(50) value of positive control is 1.46 microg/ml). Furthermore, compound 5 showed strong antibacterial activity against the Gram-positive bacterium, S. aureus.
Isolation, characterization and antimicrobial activities of polyacetylene glycosides from Coreopsis tinctoria Nutt.[Pubmed:28104231]
Phytochemistry. 2017 Apr;136:65-69.
Polyacetylene glycosides, (6Z, 12E)-tetradecadiene-8,10-diyne-1-ol-3(R)-O-beta-D-glucopyranoside (trivially named coreoside E) and (6Z, 12E)-tetradecadiene-8,10-diyne-1-ol-3(R)-O-beta-L-arabinopyranosyl-(1 --> 2)-beta-D-glucopyranoside (trivially named coreoside F), were isolated from buds of Coreopsis tinctoria Nutt., together with one known compound, Coreoside B. Their chemical structures were elucidated by extensive spectroscopic analysis and on the basis of their chemical reactivities. Coreoside E exhibited high levels of antimicrobial activity against Staphylococcus aureus and Bacillus anthracis with minimum inhibitory concentrations of 27 +/- 0.27 and 18 +/- 0.40 muM, respectively, whereas coreoside F and Coreoside B showed weak antimicrobial activity against S. aureus and B. anthracis.
