Objective : For the purpose of developing Korean herbology of the plants to Theaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : Books and research papers about Herbology which published at home and abroad were examined. Results : A list was made about Theaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Theaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Theaceae's properties flavor, channels they use, effects, and toxicity were also noted. Theaceae (grew in Korea) were divided into 6 classes with 12 species. Out of those, 4 classes with 4 species were found serviceable which indicates 33% of all. Out of all 12 species of Theaceae family, Camellia genus and Eurya genus were found 4 species, which were shown the most. Among 4 genus of Theaceae species, medicinal plants were all one species each. Out of all serviceable parts in Theaceae, Folium parts took first place as 4 species. There are toxic, the 2 species and 2 parts survefy said. Conclusion : There were totaled to 6 genera and 12 species in Theaceae in Korea and among them medicinal plants are 4 genera, 4 species, some 33% in total.

Three species belonging to genera Acaphylla Keifer and Calacarus Keifer (Prostigmata: Eriophyidae) that cause damage to Camellia (Theaceae) plants, have been newly recorded in Korea. The three species, Acaphylla theae (Watt), Acaphylla theavagrans Kadono, and Calacarus carinatus (Green), have been redescribed and illustrated. Keys to Korean species of the genus Acaphylla; their distribution; and biological information, such as host plants and damage symptoms, are also presented.

Anatomical characters of the trunk woods of Theaceae, including six genera and seven species collected in Korea, were studied to elucidate the relationship among the genera of the family. Among three genera in Ternstoemieae, Eurya is the least specialized, and Cleyera is less specialized than Ternstroemia in respect to the specialization of the perforation plate and the ray. In Theoieae consisting of three genera, the most primitive one is Thea, and Camellia is more primitive than Stewartia in the trive, from the view of the bar arrangement in scalariform perforation plate and the angle of end wall to the vessel axis. The specialization of the perforation plate of vessel element suggests that Theoieae is more advanced group than Ternstroemieae.

The plants medicinal resourees of Mt. Joghe were investigeted 10 times from January, 1988 to October, 1988. In order to analyze the vegetation of Joghemountain area, herb plants structure and distribution. Herb plants of Joghe moun-tain consisted of 102 families, 265 species in all. The resources of important herbdrugs were Gramineae, Cyperaceae Oleaceae, Araceae, Polygonaceae, Caryophyllaceae,Ranunculaceae, Theaceae, Cruciferae, Liliaceae, Rosaceae, Geranjaceae, Violaceae,Vitaceae, Umbelliferae, Labiatae, Solanaceae, Campanulaceae, Rutaceae, Compositae,Dioscoreaceae, Fagaeeae, Moraceae, Anacardiaceae, Legum inosae, Cupressaceae, andJuelandaceae. The herb drugs were comparatively more than in other mountains inour country.

Antioxidative activity, including inhibitory activities of angiotensin I converting enzyme(ACE), aminopeptidase N(APN) and $\alpha$-amylase, was investigated in the methanol extracts from Theaceae plants native to Jeju island, in order to select the plant species containing bioactive materials for functional food or medicines. ACE inhibitory activity was above 50% in Ternstroemia japonica(stem bark) and Cleyera japonica(leaf), and APN inhibitory activity was low to be positive only in C. japonica(leaf, stem bark) and T. japonica(stem bark). $\alpha$-Amylase inhibitory activity was above 30% in Camellia japonica(fruit), Eurya emarginata(stem), T. japonica(stem bark) and Thea sinensis(stem). The antioxidative activity, estimated by the DPPH radical scavenging capacity, was above 30% in C. japonica(stem bark), T. japonica(stem bark) and T. sinensis(leaf). Particularly, the antioxidative activity analyzed by dot-blot test was very high in C. japonica(stem bark) relatively to those of other plants, and remained high in the low concentration($1.25\;{\mu}g/m{\ell}$). From the TLC analysis of antioxidative compounds, EGC(Rf 0.26) was found to have high activity in stem bark of C. japonica and EGCG(Rf 0.09) was found to have high activity in stem bark of C. japonica, E. emarginata, and T. japonica. Five bands (Rf 0.54, 0.46,0.44, 0.16, 0.03) which were not identified as compared with catechins were detected as polyphenolic compounds on the TLC plates sprayed with the Folin-Ciocalteu solution or the Ferric chloride-alcohol solution. These results suggests that Theaceae plants except E. japonica could be potentially used as a resource of bioactive materials for functional foods or medicines and further research is reguired to identify the bioactive substances and determine the functions of them.

Objective : The purpose of this dissertation is to make a list of the Ceramiales growing naturally in the Korean coastal waters, and to carry out a survey on the current distribution status to investigate the Ceramiales which can be used as medicinal herbs. Methods : References and research papers about herbology published at home and abroad were examined. Results : The results of this study were as follows: 1. A total of 60 genera and 157 species of Ceramiales was found in the Korean coastal waters among which 5 genera and 6 species(approximately 4%) were medicinal plants. 2. Out of the 157 species of Ceramiales 67 species belonged to Rhodomelaceae, and out of the 6 species of medicinal plants 3 species belonged to Ceramiacera. 3. Among the medicinal parts 6 species belonged to algae. 2 species had flatness property, and 3 species had salty flavors. 4. As for the domestic distribution of medicinal plants, four species are distributed on the coast of the country, and Charmakji Caloglossa leprieuriii is distributed at the mouth of the Nakdonggang River and Goheung, Jeollanam-do. 5. 6 species had the efficacy of Spleen, stomach and large intestine meridian 2 species had the potency of remove phlegm, which helps to remove quench one's phlegm in human body. 6. None of the total medicinal Ceramiales were toxic. Conclusion : There were totaled to 60 genera and 157 species in Theaceae in Korea and among them medicinal plants are 5 genera, 9 species, some 4% in total.

To develop natural antimicrobial substances from Theaceae, Schima wallichii subsp. liukiuensis was selected from 218 woody plants, and antimicrobial compounds against bacteria, fungi, and yeast were isolated. The antimicrobial activity of ethanol extracts proved higher than those of other organic solvents. The antimicrobial activity of S. liukiuensis extract showed no differences in sesonal variation, but, that of plant part was high in bark at autumn. An antimicrobial substance was isolated from the extract of Schima using column chromatography packed with silica gel and sephadex LH-20, and then a purified antimicrobial substance (Compound I) was obtained using HPLC analysis. The Compound I in the analysis of UV, IR, and GC-MS presumed a triterpene or steroidal saponin, ${\alpha}$-sitisterol as aglycon combined three sugars. The minimal inhibitory concentration (MIC) of the Compound I against a bacteria, fungi, and yeast were 1.25 g/L, 5.0 g/L, and 0.040 g/L, respectively. This is much lower than the MIC of hinokitiol, an natural antimicrobial compound used commercially, which suggests that Compound I could be developed as a natural preservative and pharmaceuticals.
