Twenty Artemisia species are distributed in South Korea and rich in terpenoids. Artemisia rubripes (Compositae) has been used as a Korean traditional medicine for stomachache. vomiting. diarrhea and hemostatic agent. The antimutagenic effect and essential oils of Artemisia rubripes were reported, but phytochemical study has not been fully investigated. As part of our systematic study on the terpene constituents of Artemisia species. we have investigated A. rubripes (1 kg) collected at Dae-Kwan ryung. Gangwon Province on Aug. 1997. (omitted)

As part of a research program on the bioactive terpene constituents of Korean compositae plants. we have investigated Cacalia koraiensis (compositae). collected from Gangwon Province on August 2001. On reviewing the literatures of this species. triterpenes and pyrrolizidine alkaloids were isolated and some pharmacological activities were investigated. This species have been used for tinea and spasmolysis However. chemical constituents of this plant have not been reported. (omitted)

Siegesbeckia pubesence (Cempesitae). a perenial herb, is widely distributed in our country and has been used for rheumaic arthritis, hypertension, malaria. neurasthnia and snake-bite in traditional Chinese medicine. On reviewing the literatures of this plant. diterpenoids and alkaloids were isolated and some pharmacological activities were investigated. As part of our systematic study fer Korean Compositae plants, we have investigated Siegesbeckia pubesence (7kg), cellected from Mt. Odae on Aug. 2001. (omitted)

The EtOAc and CH$_2$Cl$_2$ soluble fractions from the fruit body of Ganoderma applanatum showed strong aldose reductase inhibitory activity. Nine compounds were isolated from both fractions. They were identified by spectral data as D-mannitol (1), 2-methoxyfatty acid (2), cerebrosides [(2S,3R,4E,8E)-1-O-${\beta}$-D-glucopyranosyl-3-hydroxy-2-[(R)-2'-hydroxypalmitoyl]amino-9-methyl-4,8-octadecadiene] (3), daucosterol (4), 2,5-dihydroxybenzoic acid (5), protocatechualdehyde (6), 5-dihydroergosterol (7), ergosterol peroxide (8), and cerevisterol (9).

As part of our systematic study for Korean Compositae plants, we have studied Saussurea nutans, collected at Gangwon Province on August 2001. Phytochemical studies on various species of genus Saussurea have resulted in the isolation sesquiterpene, triterpene and flavonoid$\^$1)/. S. nutans has been used for the treatment of rheumatic arthritis and dysmenorrhea in the Chinese folk medicine$\^$2)/. However, chemical constituents of this plant have not been reported until now. The MeOH extract of the aerial parts of this source was solvent fractionated into n-hexane, methylene chloride, ethyl acetate and BuOH soluble portions. (omitted)

Aster species has been used in traditional chinese medicine for treatment of a bruies and asthma. On reviewing the literatures of this species, monoterpene glycosides, diterpenoids, triterpene glycosides, cyclic pentapeptides, oligopeptides and flavonoids 1) were isolated and some pharmacological activites were investigated 2). In continuation of our search for bioative components from Korean medicinal plants, we have examined Aster spathulifolius, collected from Jeju island on August 2001. (omitted)

This study aims at providing exercisable basic data for the management of protection areas in China by investigating into their legal system such as current laws, regulations, other relevant laws and international treaties and the management system such as history, classification, organization, personnel, funds and main management work.. In People's Republic of China (1954), several laws have been enacted in succession, such as Environment Law (1989), Regulations of Natural Reserves (1994) and Land Management Methods of Natural Reserves (1995). The development process of China's natural reserves is divided into the following five phases. In the initial phase (1956-1965), about 20 natural reserves were established; in the lag phase (1966-1978), a part of the natural reserves was destroyed under the influence of the Great Cultural Revolution; in the development phase (1979-1998), a normative legal system began to appear after the reform and opening up; in the leap phase (1999-2006), the number of natural reserves increased dramatically; in the stable phase ( 2007-present), the protection and restoration of the ecological environment have been implemented, and the supervision and management have been strengthened. China has established natural reserves of national, provincial, municipal and county levels according to the relevant laws. According to the resource categories, natural reserves can be divided into natural ecosystem reserves, wildlife reserves and natural relic reserves. The Ministry of Forestry is in charge of 1,958 natural reserves which account for 74.2 % of the total natural reserves in China. In China, there are 1,384 natural reserves (52.4 %) for which management institutions have been set up. 1,702 natural reserves (64.47 %) are equipped with management staff, showing a higher ratio than the natural reserves which have set up management institutions.
