Ten green leafy vegetables were cultivated from medicinal plant seed. Their nutritional content, taste, appearance and texture were evaluated. Moisture content was $91.23{\pm}0.00%$ in $Saururus$ $chinensis$ (Sc), $90.39{\pm}0.05%$ in $Perilla$ $frutescens$ (Pa) and $66.78{\pm}0.05%$ in $Agastache$ $rugosa$ (Ar). The fat content was 8.89% in $Salvia$ $plebeia$ (Sp) and 0.13% in $Peucedanum$ $japonicum$ (Pj). The protein content was $11.1{\pm}0.00%$ in Ar and $0.54{\pm}0.03%$ in Pj. Total sugar content was $20.06{\pm}0.03%$ in $Geum$ $japonicum$ (Gj), $12.73{\pm}0.03%$ in $Coixlacry$ $majobi$ (Cm) and $1.04{\pm}0.03%$ in $Atractylodes$ $japonica$ (Aj). Medicinal leafy vegetables had higher glucose, sucrose and fructose, but lower maltose. Ascorbic acid content was $33.67{\pm}1.40$ mg% in Sc, $27.91{\pm}2.91$ mg% in Pa and $15.68{\pm}1.09$ mg% in At. Chlorophyll content was higher in $Perilla$ $frutescens$ var. $acuta$ Kudo than other leafy vegetables. The evaluation also showed that Cm, Pa and Aj tasted sweeter and had low acidity.

One hundred sixty species among Korean medicinal plants were tested on their antioxidative potentials. Antioxidants are useful materials which could be expected into development as food preservatives, health foods, cosmetics and drugs. Korean peninsula have many potential in antioxidant source which includes various medicinal herbs. It grounded on the fact that Korean medicinal plants have been used as folk therapy for long time and still do in oriental medicine. From the study, effective free radical scavengers compared with ${\alpha}-tocopherol\;of\;13.5{\mu}g/ml\;in\;RC_{50}$ were Geranium sibiricum, Geum japonicum, Geranium nepalense subsp. thunbergii and Paulownia coreana which showed $19.3{\mu}g/ml,\;22.5{\mu}g/ml,\;23.9{\mu}g/ml,\;and\;27.2{\mu}g/ml$, respectively, Acer mono and 38 plants showed strong potential in inhibition rate on linoleic acid oxidation (above 90%). In conclusion, we expect that the selected medicinal plants must be more studied as antioxidant and then developed as many industrial materials.

To assess the antioxidative activity of 12 medicinal plants on lipid peroxidation, twelves traditional medicinal plants extracted with 95% methanol were investigated the antioxidative activity using DPPH, thiocyanate acid method, and thiobarbituric acid (TBA) methods. Out of 12 medicinal plants extracted with methanol, the extraction yields of Sedum kamtschaticum was the highest values (49.46%) among them and Geranicum sibiricum, Saururus chinensis root (R), Agrimonia pilosa leaf (L), Agrimonia pilosa root was the lowest value (9.97%). Radical scavenging effect of the selected traditional medicinal plants extracted from different extract solution were examined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical method. Antioxidative activity of methanolic extracts was higher than those of ethanol and n-hexane extracts. Scavenging effects in Sedum kamtaschaticum (R) determined by DPPH radical showed the highest among the 12 plants. The antioxidative effects of the first four medicinal plants were similar to those of butylated hydroxyanisole (BHA), and butylated hydroxytoluene (BHT), but higher than that of tocopherol, which was used as a handled control. Antioxidative effects of each indicated concentration of the methanolic extracts on linoleic acid by thiocyanate method was the highest in Sedum kamtschaticum and followed by Geum japonicum and Agrimonia pilosa and their antioxidative effect were similar to those of BHA, and BHT, but higher than that of tocopherol. Antioxidative effects of the selected medicinal methanolic extract on linoleic acid by thiocyanate acid method were examined for 15 days. Peroxidation of control and tocopherol group occurred on days 5 and 9, respectively, but BHA, BHT, selected medicinal methanolic extract group did not occur until on day 15. Antioxidative effects of the selected medicinal methanolic extract on linoleic acid by TBA method were examined for 15 days. Antioxidative activity was similar to those obtained by thiocyanate acid method.

This study was conducted to select some useful plants as functional material candidates. A total of 38 plants were preliminarily screened for the anti-inflammatory and antioxidant activities. The preliminarily selected 8 plants were further investigated to verify the in vitro inhibitory effect on inflammation and oxidative stress. Boehmeria platanifolia (root), Carpinus coreana (branch), and Eupatorium japonicum (leaf) inhibited the expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-treated RAW 264.7 cells. Eupatorium japonicum (leaf) suppressed the expression of cyclooxygenase-2 (COX-2), whereas Boehmeria platanifolia (root) and Prunus yedoensis (branch) inhibited the transcription of nuclear factor-kappa B (NF-${\kappa}B$). Treatment with the extracts ($2.5{\sim}20{\mu}g/ml$) of Abutilon theophrasti (leaf, flower/seed) and Hemistepta lyrata (stem) did not show toxicity on RAW 264.7 cell proliferation, but treatment with $2.5{\mu}g/ml$ of Boehmeria platanifolia (root) exhibited cell toxicity. Carpinus coreana (branch) and Prunus yedoensis (branch) showed potent scavenging activities on peroxynitrite. Akebia quinata (flower), Carpinus coreana (branch), and Prunus yedoensis (branch) effectively inhibited reactive oxygen species (ROS). Abutilon theophrasti (leaf), Boehmeria platanifolia (root), Carpinus coreana (branch), and Eupatorium japonicum (leaf) exhibited strong inhibitory capacity with regard to nitric oxide (NO) production. The results suggested that Abutilon theophrasti (leaf) has in vitro anti-inflammatory and antioxidant activities, and that is a useful functional material candidate.
