Abstract

Crude EtO1 (ethanol maceration) obtained from aerial portions of dill was divided and eluted by solvents, to obtain PEt (petroleum ether), Eth (ethyl acetate) and EtO2 (ethanol) fractions, evaluated for total phenolics and flavonoids and antioxidant (DPPH, ABTS and FRAP assay), anti-protein denaturation, and anti-enzymatic (tyrosinase and collagenase) activities. The PEt extract was separated by column chromatography, while the chemical composition and biological effects were examined by GC-MS. All the extracts contained phenolics and flavonoids and demonstrated antioxidant activities in all assays. PEt extracts showed anti-protein denaturation (IC50 40.92 µg mL−1). A potential of collagenase inhibitor (92.35–98.69%) similar to Epigallocatechin gallate (EGCG) was noted in all extracts. Five compounds (C3, C5A, C5B2b, C9-1 and C9C9 eluted from Pet extract) represented fatty acid and fatty alcohol (nonacosan-10-one, hexadecanoic acid, ethyl ester, octacosanol, 1-hexacosanol, and hexacosanol) as major components and demonstrated inhibition of protein-denaturation (22.85–42.35% except C9-1). The compounds C9C9 and C9-1 demonstrated collagenase inhibitor effect.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
