The present study was designed to evaluate the biological potentials and
phenolic composition of different parts of Glaucosciadium cordifolium, which
is less investigated and known as a wild endemic species to Turkey. The
antioxidant activity of the plant was determined using
2,2-diphenyl-1-picrylhydrazyl (DPPH),
2,2'-Azinobis-(3-Ethylbenzthiazolin-6-Sulfonic Acid) (ABTS), iron chelating
capacity, and a ?-carotene / linoleic acid emulsion assay. The total phenol
and flavonoid contents of the plant were determined using the
Folin-Ciocalteu and aluminum chloride methods, respectively. The study of
the enzyme inhibition activity of the plant was carried out for
acetylcholinesterase, butyrylcholinesterase, ?-glucosidase, ?-amylase, and
tyrosinase. The antiglycation activity of the aqueous extract of the plant
was evaluated using established methods such as browning, a
Nitroblue-tetrazolium (NBT) assay, the 2,4-dinitrophenyl hydrazine (DNPH)
method, a Congo red assay, and fluorescent Bovine Serum Albumin (BSA). The
HPLC profiling of the phenolics revealed that 18 standard phenolic compounds
were found in different amounts in various extracts of the plant parts.
According to our bioactivity results, the methanol extract obtained from the
flower parts of the plant contained higher amounts of phenolic compounds and
flavonoids, which also demonstrated the highest DPPH radical scavenging
activity. In addition, the methanol extracts obtained from the leaves and
roots were found to be the most active extracts against the
acetylcholinesterase enzyme, as well as moderately active against the
tyrosinase enzyme. The antiglycation capacity of the extract followed this
order: G. cordifolium leaves > stems > roots > flower. As a result, our
study indicated that G. cordifolium extracts have strong antioxidant
potential, good enzyme inhibitory effects and antiglycation potential.
Further studies on G. cordifolium with in vivo bioassays need to be carried
out to seek the importance of the plant in pharmaceutical techniques.
