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.

Isoimperatorin and Oxypeucedanin isolated from root of Angelica Koreana Max. (Umbelliferae) that is used as "Kang-Whal" a botanical drug, in Korea, Show following general pharmacologic activities. The treatment with Oxypeucedanin on the exercised duodenum of the rabbit increased the motility of it while isoimperatorin shows little effects. But on the exercised heart of the frogs, both components depressed its contractility. Whereas Oxypeucedanin depressed both blood pressure of the carotied artery and respiration of the rabbit, Isoimperatorin tends to increase blood pressure, respiration and the tonus of the muscle of the earth worm. Oxypeucedanin did not affect the tonus of the muscles of the earth worm, but depressed the uterus contraction of the rabbit, which was, on the contrary, increased by Isoimperatorin.

For the investigation of medicinal resources in Hydrocotyle species, the studies were conducted to evaluate the pharmaco-constituents in Hydrocotyle japonica MAKINO (Umbelliferae), which is used as folk medicine in Korea. From the methyl alcohol extract of the whole plant, $isorhamnetin-3-O-{\beta}-D-galactoside$ ($C_{22}H_{22}O_{12}{\cdot}1/3H_2O$, bright yellow needle crystal, mp $247{\sim}248^{\circ}C$, $[{\alpha}]_D^{28}^{\circ}=-52.27^{\circ}$ in pyridine), one of three flavonol substances in extrat, was isolated and identified by physicochemical properties and spectroscopic evidences (UV, IR, NMR and MS etc.,) in comparison with authentic sample. This flavonoid was appeared from Hydrocotyle japonica MAKINO through phytochemical approaches at the outset.

A new method for the analysis of coumarin constituents in the roots of Peucedanum japonicum by high performance liquid chromatography was established. Among two coumarin constituents identified, peucedanol was confirmed to be applicable to a standard compound. A reversed phase system with a ${\mu}Bondapak$ C_{18}$, column using $H_2O-MeOH=5\;:\;4$ as a moble phase was developed. Peucedanol and a minor constituent, umbelliferone were detected at 333nm and the analysis was successfully carried out within 20 min.

Special objective of this study is to investigate morphological characteristics of seeds and effects of environmental factors such as light and temperature on their germination and seedling growth of Angelica acutilobu in Umbelliferae plants, using them as oriental medicine materials. Seed shape of Angelica acutilobu is ovate. Color of seed coats varied from yellow to dark brown. Seed size was 5.5 mm in length, 4.0mm in width. One thousand-seed weight of Angelica acutilobus was 3,210mg. Optimum temperatures for seed germination and seedling growth ranged from 20 to $25^{\circ}C$.

Several coumarins isolated from Angelica sp. were described to show inhibitory effects against human platelet aggregation. The anti-thrombotic and anti-platelet potential was evaluated, in this paper, with the BuOH soluble fraction of Angelica dahurica root. The BuOH fraction was divided into five subfractions fr. A - E and tested in the mouse model of thrombosis. Survival was enhanced to 35% with fr. A or fr. E treated (500 mg/Kg, p.o.) group of mice compared with 5% survival of the control group. However, none of the 8 coumarin glycosides obtained from fr. A, at the conc. of 0.5 mg/ml, showed inhibitory effects against rat platelet aggregation induced by ADP or collagen.

A new method for quantitative determination of byakangelicin in Angelicae dahuricae Radix by high performance liquid chromatography was established. A reversed-phase system with a ${\mu}Bondapak$ $C_{18}$ column using THF : dioxane : MeOH : HAc : 5% $H_3PO_4$ : $H_2O$=72.5 : 62.5 : 25 : 10 : 1 : 329 as a mobile phase was developed. Byakangelicin together with ter-O-byakangelicin and oxypeucedanin methanolate, and isooxypeucedanin as an internal reference were detected at 350 nm and the analysis was successfully carried out within 30 min.

Silica gel column chromatography of the ether extract of the root of Angelica decursiva $F_{RANCHET}\;et\;S_{AVATIER}$ form. albiflora $N_{AKAI}$ (Umbelliferae) gave four kinds of crystalline products of pyranocoumarin and furocoumarin: decursidin $(mp\;60{\sim}61^{\circ},\;C_{24}H_{26}O_7)$, decursin$(mp\;110{\sim}111^{\circ},\;C_{19}H_{20}O_5)$, umbelliferone $(mp\;227{\sim}228^{\circ},\;C_{9}H_{6}O_3)$, and nodakenetin $(mp\;187{\sim}189^{\circ},\;C_{14}H_{14}O_4)$. Besides, the methanol extract of the root was found to contain sucrose.

The anti-oxidant activities of decursinol angelate (1) and decursin (2) isolated from Angelica gigas were investigated. These two coumarins exhibited decrease in serum transaminase activities elevated by hepatic damage induced by $CCl_4-intoxication$ in rats. They also showed increase in anti-oxidant enzyme such as hepatic cytosolic superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-px) in $CCl_4-intoxicated$ rats. These results suggest that decursinol angelate (1) and decursin (2) from A. gigas possess not only the anti-oxidant, but also the hepatoprotective activities in rats.

The optimal condition for the determination of saikosaponin a and d, the major pharmacologically active saponins of the roots of Bupleurum falcatum, was studied with the conversion of these saponins into diene saponins $(saikosaponin\;b_1\;and\;b_2)$. The complete separation and quantitative analysis of these saponins were performed by the method of high performance liquid chromatography using $NH_2$ column. The conversion of saikosaponin a and d into diene saponins under gastric pH was calculated. Thirty-three percent of saikosaponin a was converted to saikosaponin $b_1$ and 63 percent of saikosaponin d was converted to saikosaponin $b_2$.
