Aralia continentalis Kitagawa (Araliaceae), known as "Dokwhal" in Korea, has been widely used in traditional Korean medicine for analgesia, neuralgia, sweating, and rheumatism. The biological activity was estimated with methanol extracts of from cultivated roots and adventitious roots of A. continentalis. DPPH and ABTS activities showed the highest activity in methanol extract of adventitious roots at 175.6 and $279.7{\mu}g/mL$ ($RC_{50}$), respectively. Antioxidant activity of methanol extract of the adventitious roots was higher than other samples. In the antibacterial activity assay (paper disc method), the methanol extract of adventitious roots showed activity against S. aureus, S. epidermidis, B. subtilis, and S. enterica. This study demonstrated that adventitious roots of A. continentalis, which was produced for the first time in the roots of A. continentalis, can be used as a natural antioxidant and antibacterial agents.

Wangsania, a new genus of Apiaceae from limestone areas and typified by W. insolens (Kitagawa) B.Y. Lee & J.O. Hyun, is described from Gangwon-do, Korea. Wangsania insolens was initially treated as Peucedanum insolens Kitagawa due to similarity with Peucedaunm cervaria, but it differs markedly in its unique morphological characters, such as rarely branched roots and a single basal leaf with 3 or -4 ternately dissected leaflets. These characters apparently represent apomorphies for Wangsania. The parsimony analysis of nuclaer ribosomal DNA ITS sequences revealed Wangsania to be not closely related to either Peucedanum or to any of 14 different tribes or clades within subfamily Apioideae.

Paeonol-glycoside could be extracted and isolated from the fresh roots of Pycnostelma paniculatum Kitagawa and compared with paeonolide(paeonol-6-[L-arabinosyl]-${\beta}-D-glucoside)$ by IR and UV spectra. By saponification with mineral acid, it was known that isolated glycoside was composed of aglycon and sugar parts. Aglycon was identified by comparing with paeonol by TLC and UV spectra. Of two kinds of sugar, only glucose was identified by GLC.

Objectives : In this report, we were studied the current status and future about cultivation of medicinal plants in Japan. Methods : To analysis the management and production of medicinal crops in Japan, variation of importation and cultivation of four medicinal crops such as Angelica acutiloba Kitagawa, Cnidium officinale Makino, Paeonia lactiflora Pallas and Rehmannia glutinosa Liboschitz var. purpurea Makino within 22 years ($1981{\sim}2002$) were investigated. Also we analyzed the herbal drug market in Japan using literature. Results : In the results, cultivated area and amount of Angelica acutiloba Kitagawa and Paeonia lactiflora Pallas reduced more than 50% within 22 years ($1981{\sim}2002$). Production decrease of medicinal crops is alloting through contract production in China. The cultivation of Rehmannia glutinosa Liboschitz var. purpurea Makino is enforcing minimum procluction for seed security. Conclusion : We hope that this report stimulates research to investigate for the establishment of cultural practices in Korea.

Four furocoumarins and two dihydrofuranocoumarin glycosides have been isolated from the benzene-soluble and butanol-soluble portions of the roots of Ostericum koreanum Kitagawa, respectively. Four furocoumarins have been determined as imperatorin, isoimperatorin, oxypeucedanin and oxypeucedanin hydrate, and two dihydrofuranocoumarin glycosides determined as marmesinin and $4'-O-{\beta}-D-glucopyranosyl-3'-hydroxymarmesin$ on the basis of spectral data and physico-chemical evidence.

It was revaluated about taxonomical position of the Tilingia tsusimensis (Yabe) Kitagawa (Apiaceae) collected from Mt. Gaya, Mt. Geumo, and Mt. Songni in Korea. Its diagnostic features include slightly dorsally compressed mericarps, acute-prominent ribs, ternate leaves, and dimorphic white petals. It is morphologically similar to Cymopterus and Pimpinella in having ternate leaves. It is distinguished from Cymopterus having asymmerty mericarps, 3-4 mericarp ribs, and winged dorsal ribs. Pimpinella differs in having slightly laterally compressed mericarps without ribs and conspicuous calyx teeth. Also, it looks like Angelica with obsolete calyx teeth and multilayer pericarps, but is distinguished by having its broadly winged lateral ribs and strongly dorsally compressed mericarps. Tilingia tsusimensis formed a monophyletic clade or sister group relationship with a genus Angelica based on ITS sequences. Based on the above observations, we conclude that this plant is here referred to T. tsusimensis (Yabe) Kitagawa.

Analysis of random amplified polymorphic DNAs(RAPDs) and internal morphological features were performed using three species of medicinal plants in the genus of Angelica(A. gigas Nakai, A. sinensis(Oliv.) Diels., A. acutiloba Kitagawa) to distinguish between these three species. Fifty decarmer oligonucleotide primers were screened for the RAPDs of the herbal plant species. Five primers generated distinct RAPD markers specific to the species of Angelica, In analysis of the degree of similarity, A. sinensis(Oliv.) Diels is more closely related to A. acutiloba Kitagawa than to A. gigas Nakai. Furthermore, we proved the usefulness of RAPD analysis for the discrimination of the species using dry roots and commercial plant materials. In internal morphology of three species, A. sinensis(Oliv.) Diels seemed to be more specialized in systemic than A. acutiloba Kitagawa and A. gigas Nakai
