چکیده انگلیسی
The variation of antioxidant activity and active components in pyrola [Passiflora incarnata Fisch.] from eight sites in Northeast China were investigated. Total phenolic and flavonoid contents were determined and varied within the range of 39.66-181.48 mg/g and 2.47-22.11 mg/g, respectively. Antioxidant activities were determined by scavenging activity against DPPH and ABTS, by a reducing power test and by a β-carotene-linoleic acid bleaching test. The IC50 of Tahe samples determined by the DPPH test was 0.106 ± 0.006 mg/mL which was very close to that of Vc (0.076 ± 0.004 mg/mL). The Tahe samples had good antioxidant activity. Principal component activity analysis indicated that the Tahe samples of P. incarnata had the highest potential antioxidant properties, and may be a valuable antioxidant natural resource in the northeast of China.
