Soluble protein content in crude extracts from leaves (sampled in December, LD and March, LM) and inflorescence (INF) of C. albuma. Activity of antioxidant enzymes –b superoxide dismutase (SOD), c ascorbate peroxidase (APX), d guaiacol peroxidase (POX), e catalase (CAT), f glutathione reductase (GR), g dehydroascorbate reductase (DHAR) and h monodehydroascorbate reductase (MDHAR) in leaves and inflorescence of C. album. Crude extracts were subjected to different incubation temperatures (5–100 °C) for 30′. LD (white square), LM (black square) and INF (black triangle). Error bars indicate ± SE (n = 3). In some cases error bars are smaller than the symbol. FW indicates fresh weight. Arrows indicate the temperature at which sharp decline in activity was observed
