ABSTRACT
Objective:
To investigate the antioxidant and glucosidase properties and phytochemical constituents of roots, stems, leaves and flowers extracts and aerial parts oil of Chrysanthoglossum trifurcatum (Desf.) (C. trifurcatum).Methods:
For extraction from roots, stems, leaves and flowers of C. trifurcatum, methanol, ethyl acetate and petroleum ether solvents were used. Phenols, flavonoids, flavonols and tannins contents were evaluated. More, C. trifurcatum aerial parts oil composition was determined using chromatography/mass spectrometry. The antioxidant effect was estimated by DPPH, ABTS and reducing power test systems. The glucosidase inhibition was determined by colorimetric assay using the enzyme from Aspergillus Niger and the p-nitrophenyl glucopyranoside (pNPG) as substrate.Results:
The highest amounts of polyphenols, flavonoids, flavonols and tannins were shown by the methanolic extract of leaves. The main components of the aerial parts oil were limonene (29.21%), γ -terpinene (12.96%), 4-terpenyl acetate (12.18%) and pinene (5.76%). The activity evaluated by DPPH, ABTS and reducing power tests was important for stems (IC
