Antioxidant and scavenging capacity of Anacamptis pyrimidalis L.--pyrimidal orchid from Vojvodina.
In the present study we investigated the antioxidative properties of flowers and aboveground part of Anacamptis pyrimidalis L. from Vojvodina. Activities of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, and glutathione peroxidase), quantities of malonyldialdehyde, superoxide and hydroxyl radicals and reduced glutathione and also the contents of chlorophylls a and b, carotenoids and soluble proteins were determined. Lipofuscin 'plant age pigments', total antioxidant capacity and scavenging activity were also determined. Our results indicated that the aboveground part of the plant exhibited higher antioxidant activity due to low MDA and lipofuscin pigment accumulation (2.82 nmol/mg protein; 92.90%), higher scavenging activity (54.16%) and antioxidant capacity (432.00 micromol Fe(2+)/dm(3)).
