Table 2.

Antioxidant activities of different compounds expressed as IC₅₀ values (μmol/L) from in vitro assays of DPPH (I) and superoxide anion (II) scavenging and lipid peroxidation inhibition (III).

	PICE	PICG	RES	POD	Vc	EDA
I	138.9	149.8	167.2	—	77.5	62.6
II	124.6	305.2	438.3	—	18.97	—
III	31.28	—	37.70	72.89	166.4	29.65

— indicated that the activity was rather weak and therefore IC₅₀ value could not be calculated.
