摘要

Acomprehensive analysis of Crocus specious M. growing in the Goris region of Armenia was conducted. The chemical composition of the EtOH extract of plant stigmas was studied using gas chromatography-mass spectrometry (GC-MS) to reveal 28 compounds. The dominant constituents were L-(+)-ascorbic acid 2,6-dihexadecanoate (30.812 wt%) and hexadecane (2.999 wt%). The antioxidant properties of the extract were investigated using a kinetic method based on the model reaction of initiated cumene oxidation. The effective antioxidant content was established as 0.83 × 10–4 M; their activity, 2.41 × 105 L/mol·s at 384 K, which exceeded some synthetic antioxidants. The elemental composition of the stigmas included 31 elements as determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). High contents of potassium (28,174.04 mg/kg) and iron (1,471.12 mg/kg) were revealed. The contents of heavy metals did not exceed the maximum permissible concentrations. The results expanded knowledge about the chemical composition and properties of Crocus specious M. and opened up prospects for its use as a natural antioxidant.
