| In this studies, contents and activities of antioxidative substances in the fruits of a pear cultivar and five Korean wild pear lines were investigated. The content of total phenolic compounds was highest with Pyrus pyrifolia var. culta "Shingo" (7.68 $mg{cdot}g^{-1}$, D.W.) while total flavonoids was highest with P. ussuriensis var. acidula (5.66 $mg{cdot}g^{-1}$, D.W.). The contents of total polyphenols and flavonoids varied according to plant species, but in general pyrifolia lines had higher total polyphenols than total flavonoids whereas in ussuriensis lines total flavonoid contents were higher than total polyphenols. The scavenging effects of DDPH radicals was highest with highest with P. ussuriensis var. seoulensis ($RC_{50}$=1.45 $mg{cdot}mL^{-1}$) and that of ABTS radicals was highest with P. ussuriensis var. acidula ($RC_{50}$=0.69 $mg{cdot}mL^{-1}$). A pear cultivar "Shingo" showed highest total polyphenol content, but scavenging activity of DDPH and ABTS radicals was lowest. The fruits of P. ussuriensis var. seoulensis contained low level of phenolic compounds, but their scavenging effects on two radicals was superior. Ferrous ion chelating effect was high in P. pyrifolia var. culta (98.93%), and in P. ussuriensis var. sinensis (68.71%), but two species had low scavenging activity. The content of phenolic compounds in wild pears was not always directly proportional to the radical scavenging activity. Neither radical scavenging activity was to ferrous ion chelating activity. In conclusion the fruits of P. ussuriensis var. acidula, P. ussuriensis var. seoulensis, and P. ussuriensis var. sinensis had great potential for the development of new antioxidative functional food because their antioxidative activity is higher or at least similar to P. pyrifolia var. culta. However, due to their different levels of antioxidative effects, the development of methods of using them jointly, not singly, to obtain maximum level of antioxidants is recommended. |
