Menthol (M) is a cyclic monoterpenode and is a major component of essential oils. Menthol, along with menthol, isomenton, etc., gives taste and odor of the mint plant, and when it comes to menthol in general, L- or (-) -menthol is usually used. Included in pharmaceuticals, cosmetics and pesticides. It has antimicrobial, antibacterial, antioxidant properties. It is also known that the licorice plant (Glycyrrhiza Glabra L.) differs from other types of plants by its medicinal properties. For many years it has been used in folk medicine. Extraction of licorice root revealed up to 25% glycyrrhizinic acid (GA). Its aglycone - glycyrrhizic acid is notable for its structural similarity to the adrenal cortex hormones. Currently, GA and glycyrrhizic acid are widely used in medicine as a remedy for colds, allergies, viral diseases, tumors. The biological activity of menthol and GA-based supramolecular compounds has been poorly studied, and their effect on the functional parameters of rat liver mitochondria has been studied little. For this purpose, in our experiments, the effect of menthol (M), glycyrrhizinic acid (GA) and their supramolecular complexes obtained in different proportions on in vitro and in vivo studies on rat liver mitochondria was studied.

A Korean folk medicine, "DangYak (當藥)" has been used as a bitter stomachic in Korea. With regard to the botanical origin of this crude drug, it has been considered to be from Swertia species (Gentianaceae), but there was no pharmacognostical confirmation on it. In this study, the morphological and anatomical characteristics of three Swertia species growing in Korea, Swertia japonica Makino, S. pseudochinensis Hara and S. tetrapetala Pall. were compared to clarify the botanical origin of "DangYak". As a result, it was determined that the commercial "DangYak" from Korean traditional market was proved to be the whole plant body mixture of Swertia japonica and Swertia pseudochinensis.

The nation-wide medicinal plants list is prepared on the basis of the collected plant samples from 22 places of 9 regions where the authors possiblely surveyed and the references on field survey reported by others. No one has reported this kind of list before and the Engler's classification system is applied in this list instead of the previously applied Nakai's classification system. And also Korean name, occurrence, distribution, medicinal part, and name of crude drugs are described in the list. According to the results of this study, the number of the natural and cultivated medicinal plants in Korea are 950 kinds presently; i.e., 719 species, 1 subspecies, 209 varieties, 1 subvariety and 20 formas which belong to 142 families and 437 genera. Out of the 950 medicinal plants, cryptogamae are 22, herbs 550 and woodies are 278. The usual common drugs are 284 kinds and the allied plants are estimated 160 kinds. And there are some folk medicines and un-utillized medicinal plants.

Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

Prickly pear(Opuntia ficus-indica var saboten Makino, Cactaceae) is widely used as folk medicine for burned wound, edema and indigestion. To confirm the hypolipidemic action of the extract from Cactus stem and fruit in dietary hyperlipidemic rats, variations of the lipid- or cholesterol-related components were investigated. As results these changes were significantly prevented by treatments with Cactus extracts. The effects of the extract of fruit was better than those of stem.

Chinese crude drug "Lu-ti-cao"(鹿蹄草) has been used as a remedy for beriberi, cut bleeding, snake bite, etc. In Korea, the drug is called "Nok Je Cho" and has been used as a folk medicine of the same effect as that of Chinese equivalent. The original plant of this drug has not yet been as certained. To clarify the botanical origin of "Nok Je Cho", the morphological and anatomical characteristics of the leaves of Pyrola species growing in Korea, i.e. P. incarnata, P. japonica, P. minor, P. renifolia, P. secunda were studied. As a result, it was clarified that "Nok Je Cho" was the leaf of Pyrola japonica and Pyrola minor.

Spiraea japonica L. F., a plant species belongs to the Spiraea genus of Rosaceae family, has seven varieties. There are all varieties distributed in Yunnan province of China, and S. japonica var. acuminata and S. japonica var. fortunei were used as the folk medicines to treat malaria and inflammation etc.. Since 1960s, Japanese and Russian scholars obtained C$\_$20/-diterpenoid alkaloids from S. japonica L.F., also Chinese scholars got a series of Hetisine-type C$\_$20/-diterpenoid alkaloids from S. japonica var. fortunei in 1985. Since then, we started the chemical and pharmaceutical studies of this complex. Here we wish to report the bioactive effects of spiramine alkaloids and their derivatives on the platelet aggregation induced by AA, PAF, or ADP.

Dendropanax morbifera Leveille, an endemic species in Korea, is best known as a tree that produces a resinous sap. Although D. morbifera is used in folk medicine for various diseases, its active ingredients are largely unknown. In this study, we investigated antioxidative activities of ethanolic extracts of three parts of this plant including leaves, debarked stems, and roots. The root extracts exhibited strong 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging activity compared with leaf or stem extracts. The root extracts showed hepatoprotective activity against t-butyl hydroperoxide-induced HepG2 cells, and reduced the ROS level in the cells. The root fractions lowered the mRNA level of COX-2 on lipopolysaccharide-stimulated Raw246.7 cells. These results suggest that ethanolic root extracts of D. morbifera are a source of antioxidant and hepatoprotective compounds, which indicate a potential for a botanical drug.

Two new 1,2-seco-1-nor-6((5 $\mapsto$ 10)abeo-picrasan-2,5-olideskeleton quassinoids, eurylactones A [1] and B [2], and two new $C_{19}$ skeleton quassinoids 3 and 4 were isolated from Eurycoma longifolia together with two known $C_{18}$ quassinoids 5 and 6. Their sttuctures were established by the spectral evidence.Many quassinoids have already been isolated (1-3) from the roots, wood, and leaves of Eurycoma longiolia Jack (Simaroubaceae) and have been used as a folk medicine insoutheast Asia. As part of a series of studies, we have further undertaken the chemicalinvestigation of the n-BuOH-soluble fraction of the MeOH extract and isolated two new1,2-seco-1-nor-6(5 $\mapsto$ 10)abeo-picrasane skeleton quassinoids 1 and 2, which have beenknown only in shinjulactone B (4,5) and yadanfiolide (6), two new $C_{19}$-type quasslnolds3 and 4, and two known C18-type quassinoids 5 and 6. In this paper, the structureelucidation and biosenetic relation of these compounds are described.
