Data from the 2001 Korea Health and Nutrition Examination Survey, a nationally representative, cross-sectional survey, were analyzed to assess prevalence of health intended food use overall and in relation to socio-demographic and lifestyle characteristics. Health intended food were classified into four broadly defined categories: vitamin and mineral supplements, health aid food, animal protein based restorative food and medicinal plants. Thirty three percent of adults aged 20 years or older reported taking health intended food in the past year : twenty four percent took vitamin or mineral supplements and medicinal plants were taken by 17 % of adults, health aid food by 15% and animal protein based restorative food by 6%. In multivariate logistic regression, female gender, older age, more education, regular exercise and non smoking were associated with greater use of vitamin or mineral supplements. Dietary quality was significantly associated with use of vitamin or mineral supplements or health aid food but not with use of medicinal plants or animal protein based restorative foods. Obese persons were less likely to take vitamin or mineral supplements. These findings suggest that epidemiologic studies of diet, demographic or lifestyle and health take health intended food use into account because of high prevalence of use of the food by the population and differential use of the food by socio-demographic and lifestyle characteristics.

A study was conducted to evaluate the nutritive potential value of different aquatic plants: duckweed (Lemna trisulaca), duckweed (Lemna perpusila), azolla (Azolla pinnata) and water-hyacinth (Eichhornia crassipes) from Bangladesh. A wide variability in protein, mineral composition, gas production, microbial protein synthesis, rumen degradable nitrogen and in situ dry matter and crude protein degradability were recorded among species. Crude protein content ranged from 139 to 330 g/kg dry matter (DM). All species were relatively high in Ca, P, Na, content and very rich in K, Fe, Mg, Mn, Cu and Zn concentration. The rate of gas production was highest in azolla and lowest in water-hyacinth. A similar trend was observed with in situ DM degradability. Crude protein degradability was highest in duckweed. Microbial protein formation at 24 h incubation ranged from 38.6-47.2 mg and in vitro rumen degradable nitrogen between 31.5 and 48.4%. Based on the present findings it is concluded that aquatic species have potential as supplementary diet to livestock.

The anti-inflammatory and analgesic action of the components isolated from some edible plants carried out. We isolated the quercitrin, compound 3 and o-counmaric acid from Cedrela sinensis, Oenanthe javanica and Artemisia princeps var. Orientalis respectively. O-coumaric acid showed the inhibitory effect on carrageenin-induced edema as well as vascular permeability in mice. And we also found the analgesic activity in all compounds isolated from these plants.

There is great demand of nutraceutical secondary metabolites in the world so as to feed the population by improving agricultural production with new varieties of food crops but what is still more important is to add nutrition into the food. Physalis minima, plant of Solanaceae family, contain certain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals that are generally regarded as safe. These chemicals are almost monopoly of the plants of Solanaceae. The leaves, stem and roots of P. minima have been examined to yield several steroids, identification of which has been discussed in this paper. These withasteroids contribute to the potential nutraceutical and health function value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.

The purpose of this study was to investigate the effects of oriental medicinal plant extracts added to chocolates on the moisture content, color, radical scavenging activity and sensory characteristics. The oriental medicinal plant extracts were added at a weight percentage of 0, 4 and 8%. As the ratio of the extracts in the chocolates increased, the moisture content, color, and radical scavenging activity increased. In sensory evaluation, significant differences (p<0.05) were shown in taste, bitterness, and overall acceptability depending on the addition of oriental medicinal plant extracts but there were no significant differences in chocolate aroma and texture.

Phenolic compounds in food and plant materials belong to the simple phenols, phenolic acids, coumarins, flavonoids, stilbenes, tannins, lignans and lignins, all of which are considered as secondary plant metabolites. These compounds may be synthesized by plants during normal development or in response to stress conditions. Phenolics are not distributed uniformly in plants. Insoluble phenolics are components of cell walls while soluble ones are present in vacuoles. A cursory account of phenolics of cereals, beans, pulses, fruits, vegetables and oilseeds is provided in this overview. The information on the bioavailability and absorption of plant phenolics remains fragmentary and diverse. Pharmacological potentials of food phenolics ave extensively evaluated. However, there are many challenges that must be overcome in order to fully understand both the function of phenolics in plant as well as their health effects.

When relations improve between North and South Korea, there will be demand for North Korean edible plants because of the low labor cost and similar environmental conditions. However, there is no reliable information about trace elements, metals, and metalloids in edible plants from North Korea. Selenium (Se) and germanium (Ge) have positive effects on basic human health and are therapeutical in diverse illnesses. Metal and metalloid (Cd, Pb) poisoning, on the other hand, can cause many health problems. Plants collected from North Korea had higher selenium content than those from South Korea. Although none of the collected species exceeded the permissible levels of cadmium and lead, their content in plants was significantly higher in North Korea than in South Korea. The high metal contents in plants collected from North Korea may be associated with the soil physicochemical properties as well as the accumulated amounts of elements in the soil.

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.
