Korean folk medicine 'SaCheolNaMuIp' has been used to cure jaundice. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'SaCheolNaMuIp', the morphological and anatomical characteristics of the leaves of Euonymus species growing in Korea, i.e. E. japonica and E. fortunei var. radicans were studied. As a result, it was clarifyed that SaCheolNaMuIp was the leaf of Euonymus japonica.

"SaCheolNaMu" has been used as a Korean folk medicine for the jaundice, lumbago and uterine diseases. Although a crude drug related to this folk medicine is sold in traditional herbal market, the botanical origin of this drug has not been pharmacognostically confirmed yet. In this study, the morphological and anatomical characteristics of the stem of Euonymus species growing in Korea, i.e. Euonymus japonica and E. fortunei var. radicans were studied to clarify the botanical origin of "SaCheolNaMu". As a result, it was found that these two species could be discriminated by the morphological criteria such as the thickness of cuticles, the number of collenchyma cell layers, and the frequency of druse and resinous substance. According to these criteria, it was elucidated that the commercial folk medicine "SaCheolNaMu" was the stem of E. japonica. Meanwhile, HPLC-DAD analysis on the 70% ethanolic extracts of two species showed significantly different HPLC profiles each other. The molecular ions of three characteristic peaks shown in the chromatogram of two species were identified by ESI-MS, and their structures were estimated to be flavonol glycosides.

Chemical components and physiological activities of acorn powders were investigated to develop functional food. Proximate components were 87.29% crude fiber, 1.18% crude fat, 0.84% crude protein, and 0.12% crude ash. Potassium was most predominant mineral, followed by phosphorus, calcium, magnesium, and sodium. Contents of unsaturated fatty acids, such as oleic, linoleic, and linolenic acids, were higher than those of saturated fatty acids. Water and 75% ethanol extracts of acorn powders showed higher absorbency at 285 nm. Water and 75% ethanol extracts exhibited antioxidative activity with $IC_{50}$ of 19.0 and $21.4\;{\mu}g/mL$, respectively, indicating they are the major biological component in acorn powders. Results suggest water extract of acorn can be used as new material for natural antioxidant and functional food.

Food constituents analysis of Acer tegmentosum. Maxim.(Acer TM) stem was carried out according to AOAC method, and the antiradical activity on DPPH and cytotoxicity on human cell lines (AGS, HepG2, A549, MCF-7 and Chang) for the 80% ethylalcohol(EtOH) extracts of Acer TM stem were studied. The antiradical activity on DPPH radical of the ethylacetate(EtOAc) fraction of the bark showed a higher activity than that of $\alpha$-tocopherol, ascorbic acid and BHT. The inhibition activity of the 80% EtOH extracts from Acer TM stem on human cancer cell lines by SRB assay indicated a dose-dependent growth inhibition on most human carcinoma cells. The growth inhibition rate of each human cancer cell line showed 91.3% to AGS, 75.0% to A549, 74.1% to HepG2, and 70.2% to MCF-7 cells, respectively, when the 80% EtOH extract(1 mg/ml) of Acer TM stem was added.
