The freshness , desirablefatty acid composition and beneficial vitamin content of meat and milk depend upon the antioxidant content , vitamin profiles ,and fatty acid content and composition of animal feeds ( Scollan et al . , ２００５ ) . In a previous report ( Tamura and Masumizu ,２００５ ) , we showed large differences in antioxidant activities among some pasture species . In this study , we determined andcompared antioxidant activities , vitamin profiles and polyphenol contents of the principal herbage grasses and legumes , herbsand wild plants at the vegetative grow th stage in northern Japan .Materials and methods Seven herbage grasses , two herbage legumes and two herbs in artificial swards from lowland ( １７７ mabove sea level) and highland (９２０ m above sea level) pastures , and five wild plants from natural pasture were used ( Figure１ ) . Superoxide anion radical ( O２ ‐ ) scavenging activities ( SOSA ) of both water‐and methanol‐soluble extracts ; vitamins A , Cand E contents ; and total water‐and methanol‐soluble polyphenol contents were determined by the spin‐trapping method usingan electron spin resonance spectrometer ( ESR , JES‐FA２００ JEOL Ltd .) , by the high performance liquid chromatographymethod using HPLC ( LC １０AS systems , Shimazu Co . , L td .) , and by the Folin‐Denis colorimetric method , respectively .Results and discussion The SOSA for both water and MeOH extracts differed significantly among species . Water‐extractedSOSA was higher in T ri f olium repens L . , Plantago lanceolata L . and V iola gry poceras A . , while MeOH‐extracted SOSAwas higher in P . lanceolata , Taraxacum o f f icinale Weber and wild plants . Vitamin A and E contents were higher in grassesand lower in Medicago sativ a L . , T . o f f icinale and wild plants , while vitamin C content was higher in herbage legumes andwild plants and lower in herbs . MeOH‐extracted total polyphenol contents showed tendencies similar to those observed for theMeOH‐extracted SOSA , with a few exceptions . However , the contribution ratios ( R２ ) in a regression of the total polyphenolcontent to the SOSA were low .low land artificiced pasture Highland artificial Natural pasture .Figure 1 MeOH‐ex tracted SOSA and V itamin A contents o f herbage grasses and legumes ,herbs and w ilds p lants .Note :L P ;Lolium perenne L . ,DG ;Dactylis glomerata L . ,PP ;Phleum pratense L . ,PA ;Phalaris arundinacea L . ,PO ;Poa pratensis L . ,AR ;Agropyron repense (L ) P .Beauv . ,ZJ ;Zoysia japonica Steud . ,MS ;Medicago sativa L . ,TR ;Trifolium repens L . ,PL ;Plantago lanceolata L . ,TO ;Taraxacum officinale Weber . ,CO ;Carexoxyandra Kudo . ,PB ;Potentilla freyniana Bornm . ,PF ;Potentilla fragarioides L .var .major Maxim . ,VG ;Viola grypoceras A .Gray Regarding Tukey摧s Studentizedrange test f or the MeOH‐ex tracted SOSA f or Low land arti f icial pasture ,we did the analysis tw ice , f irst all species and secondly only f or pastures to detectsigni f icant di f f eemces among grasses and legumes .V alues w ith di f f erent superscrip ts di f f ered signi f icantly ( P ＜ 0 .05) .Conclusions We found very large differences in SOSA among herbage grasses and legumes , herbs , and wild plants . The resultsof this experiment will be useful for producing improved animal products , and some of the species , especially P . lanceolata ,could be used as natural sources of antioxidants against superoxide anion radicals .ReferencesScollan , N .D . , Dewhurst , R .J . , Moloney , A .P . , Murphy , J .J . , ２００５ .
