Abstract
This experiment was conducted to find out high antioxidant activity varieties of chinese matrimony from the 131 accessions which conserved at Cheongyang Gugija Experiment Station. The status of the 131 accessions were composed 21 of local varieties, 20 of introduced species and 90 of improved races. The anti-oxidant activity using DPPH and $IC_{50}$, 45 accessions out of 90 showed high activity in free radical scavenging ability as less than $200{\mu}g/m{\ell}$ in improved races, while nine and six accessions from the introduced species and local varieties, respectively. At the stem part, the highest three anti-oxidant varieties among 131 accessions are "C0148-94", "D0148-72" and "Cheongdae", while China collection 1 in leaf part. Since "Cheongdae" is the progeny from the "Cheongyang Jaerae 5" and "Myungan" and those two varieties, "C0148-94" and "D0148-72" are from the Myungan and Cheongdae, high anti-oxidant activity can be inherited in Chinese matrimony vine.
