This study was investigated on antioxidant activities of methanol, ethanol, and water extracts of 42 herbs. The herbs grown at Dankook university practice greenhouse. Through the examination of methanol, ethanol , and water extracts from 42 herbs for radical scavenging effects using DPPH method. Antioxidant activities of each solvent extracts were not similar or lower than that ascorbic acid. The IC50 value of antioxidant activities have range 400-200 in about 25% of herbs and water extract showed higher antioxidant activity more than methanol and ethanol extracts. Antioxidant activities in methanol extract were in order of lemon balm>pappermint>oregano, ethanol extract of sweet majoram>oregano>spearmint, and water extract of beramot mixed>lemon balm> oregano. Lemon balm, oregano, red basil , spearmint among 42 herbs showed the highest antioxidive activity and water extract was excellent results than other extracts.

MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium) assay were used to analyze anticancer activities from herbal plants. This study was conducted to inhibit the human lung cancer(A549) cell line in vitro. The 1C50 value of cytotoxicity showed range of 127.83-2018 .1 9μg/m~. Especially Coriander( 127.83μg/mR} and Catnip(140.68μg/me.) showed more stronger activity than other plants, respectively.

This research paper was studied about current status and utility value of the anthocyanin pigment, according to rise of interest. This was based on past paper and studied current status about anthocyanin pigment of individually crop. And we studied and drew up question form in order to judge utility value of functional food. Analysis showed that it was high recognition of anthocyanin and functional food. Also, the older age rose , the higher distribution of recognition. This recognition was the most by broadcasting. And most people thought that the major effect of anthocyanin is anti oxidation , anti cancer. Also, the older ate the more functional food for the health. We should perform the functional food development, taking advantage of antioxidation, anticancer of anthocyanin. Therefore, the market of the functional food taking advantage of Anthocyanin pigment will grow up.

DPPH(l, 1-diphenyl-2-picrylhydrazyl) free radical scavenging activity assay was used to analyze antioxidant activities in 249 Korean rice landraces. Especially, red rice varieties were 13 accessions, showed very strong antioxidant activities more than 95%. Brown rice varieties were 236 accessions, among them G307 showed the highest antioxidant activity of 68%. Most of brown rice varieties showed higher activities than Chucheongbyeo as check variety. 101 accessions were distributed range of 21 - 30% and 71 accessions were distributed range of 31 -40%.

DPPH(l, 1-diphenyl-2-picrylhydrazyl) free radical scavenging activity assay was used to analyze antioxidant activities in 78 pigmented rice germplasms. Out of 79 varieties taken, 28 varieties showed >70%, 27 varieties showed 61-70% whereas the rest of the varieties showed less than 60% antioxidant activity. In relative total anthocyanin content, Tingga loko( 1.972mg%), Ane bonak(l.965mg%), Pulut mbiring(1.926mg%), and so on were present at concentration given in the descending order, which lies within the range of 0.028 -1.972mg%.
