The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

To check the possibility of using natural extracts for cosmetic substances, we tested the bioactive effects of 11 crude extracts originating from native plants grown in the Republic of Korea on anti-oxidant and anti-wrinkle activities. When DPPH scavenging activities were measured, the crude extracts of Vitex rotundifolia, Scirpus triangulatus, S. wichurae, S. tabernaemontani, and Aeschynomene indica assays had more than 70% of DPPH scavenging activities at 100 μg/ml concentration. The data from the hydrogen peroxide scavenging assay revealed that the crude extracts from the 10 species, except for Eleocharis mamillata var. cyclocarpa, could scavenge more than 90% at 1,000 μg/ml concentration. The crude extract of V. rotundifolia had the highest xanthine oxidase scavenging activity at a 1,000 μg/ml concentration. Based on the four anti-oxidant assays, the crude extracts of V. rotundifolia, S. triangulatus, S. wichurae, S. tabernaemontani, and A. indica were shown to have excellent anti-oxidant capacities overall. In addition to the anti-oxidant capacities, the crude extract from S. wichurae exhibited high collagenase inhibitory activity, therefore, it could be a promising candidate for a cosmetic ingredient with anti-oxidant and anti-wrinkle qualities. The results of this study indicate that many wild plants native to the Korea Peninsula can be used as excellent natural substances for cosmetics based on their bioactive effects.

Korea is one of the Northeast Asian countries in the Northern climatic zone. It is wide spread from north to south so that can be affected by various kinds of plants flora of the continent of Asia. Korea has complicated topography, mountains and hills included by an alpine belt. According to the distribution of plants, it can be classified to 5 areas; Northern part, Central part, Southern part, JeJuDo(濟州道) and UlLungDo(鬱陵島). Nakai of Japan, reported Plants in Korean peninsula as 3176 species, 841 varietal species and 174 varieties in "A Synoptical sketch of Korean flora". Lee of Korea, reported 3409 species, 6 sub-species, 756 varietal species and 287 varieties in "Korean Plants Resources". Isidoja(石戶谷) of Japan, simply described crude drug names, scientific names, effects, etc. of 45 species of Korean Medicinal Plants in the book "Journal of Jo-Seon Pharmacy(朝鮮藥學會會報)" third edition (published in 1925) and also explained 250 species of crude drug collected in Manchuria, Mongolia and Korean peninsula in the book "Medicinal plants in Northern Asia(北支那의 藥草)"(1931). Im and Jung organized 227 species of Medicinal Plants in "Wild Medicinal Plants from Jo-Seon(北支那의 藥草)" and it is said that 1000 species of plants can be used for medicinal purposes in Korea.

The Chinese crude drug, 'Man Sam(蔓蔘)', which is derived from the root of Codonopsis plants of the family Campanulaceae, has been used as a tonic. In China, the same crude drug derived from Codonopsis plants, called 'Dang Same(?蔘)', has been used as remedies for anorexia, fatigue, cough, etc. Although Codonopsis roots have been widely used for medicinal purposes in Korea, the botanical origin of the crude drug has never been studied pharmcognostically. To clarify the botanical origin of 'Man Sam', the root morphology and anatomy were examined for the Korean species of Codonopsis species, such as C. lanceolata (Sieb. et Zucc.) Trautv., C. pilosula (Franch.) Nannf. and C. ussuriensis (Rupr. et Maxim.) Hemsl. The study shows that 'Man Sam' is the root of Codonopsis pilosula.

Thirty plants of the Compositae family were screened for inhibitory activity of angiotensin converting enzyme (ACE). Among them, Chrysanthemum boreale Makino and Ixeris dentate Nakai were selected for further investigation since they had the highest inhibitory activity. Crude water extracts of the flowers of Chrysanthemum boreale Makino and the roots of Ixeris dentate Nakai were prepared by heating at 95$^{\circ}C$ and 6$0^{\circ}C$ for 2 hr, respectively, followed by centrifugation at 8000$\times$ g far 30 min. Crude extracts were then filtered using YM-3 and YM-1 membranes. The ACE inhibitors were isolated using consecutive chromatographic methods including: Sephadex G-15, ion exchange, FPLC, and reverse phase HPLC. The inhibitors were identified to have molecular masses of 204 and 283 daltons, respectively, by mass spectrometry. These results demonstrate that crude extracts of Compositae plants may be useful as functional food ingredients with anti-hypertensive properties.

The proximate composition of 3 kinds of Umbelliferaeceae Wild Plants (Angelica gigas NAKAI., Ostericum sieboldii NAKAI. and Coriandrum sativum LINNAEUS) were analyzed and used for making pork sausages as a functional ingredient. In the proximate composition, crude protein content was the highest in Ostericum sieboldii, 37.87%, and crude lipid and crude ash contents were the highest in Coriandrum sativum. Vitamin C was contained in Angelica gigas at 0.30mg%. but was not detected in Ostericum sieboldii and Coriandrum sativum. $\beta$-carotene content in Angelica gigas was the highest at 19.96%, but selenium was not detected in any of them. Total phenol content in Coriandrum sativum was the highest as 1107.43mg%. TBA and VBN values of all sausages with wild plants increased gradually during four-week-storage and were lower than those of control. Coriandrum sativum-added sausage had the lowest TBA as well as VBN valuew. During the four-week-storage at 4$\^{C}$, TBA value and VBN value were in the very safe range at all sample. Total phenol contents in sausages appeared to have more antioxidative activity than vitamin C, $\beta$-carotene and selenium, and consequently decreased the TBA values of sausages.
