  • Artemisia asiatica Nakai aqua-acupuncture solution (ANAS) was administered once daily for 10 days before the tumor implantation ($1{\times}10^6\;cells$). Body weight, spleen weight and the number of ascitic tumor cells were measured at 6 days after tumor implantation. The change of body weight and the survival rate of mice were observed for 21 days. It was used three biomarkers (quinone reductase, glutathione, glutathione S-transferase) to test chemopreventive potentials of ANAS. ANAS exerted antitumor activity by inhibiting the growth of Ehrlich ascites tumor cells in vivo. Mice given Ehrlich cells and ANAS at $CV_{12}$ and $BL_{18}$ had 57.1% to 49.2% survival after 21 days. Quinone reductase activity and glutathione levels were increased with ANAS. However, glutathione S-transferase level was 1.1-fold with ANAS. These results suggest that ANAS has chemopreventive potential by inducing QR activity and increasing GSH level.

  • The purpose of this study was to examine the potential for the development of radioprotective agent in extracts manufactured by mixing Artemisia asiatica Nakai and Moringa oleifera Lam known as antioxidant food with the appropriate ratio. Their whole body were irradiated 7Gy radiation after oral administration of a mixed extract of Artemisia asiatica Nakai and Moringa oleifera Lam to SD Rat for two weeks. And 1 day, 7days, 21days later, changes in blood cell components, SOD activations and tissue changes in the uterus were observed.It was confirmed that the AM + IR group had a higher tendency to recover leukocyte (p<0.05) and platelet (p<0.05) levels than the IR group. It was also confirmed that SOD activity was increased and cell death was decreased in uterine tissue.Based on these results, the mixed extract of A and B is expected to be useful as a radiation protection agent capable of reducing blood cell and uterine damage caused by radiation exposure.

  • Aerial parts of Artemisia asiatica (Compositae) have been traditionally used as an oriental medicine for the treatment of inflammatory and ulcerogenic diseases. In the present study, artemisolide was isolated as a nuclear factor $(NF)-{\kappa}B$ inhibitor from A. asiatica by activity-guided fractionation. Artemisolide inhibited $NF-{\kappa}B$ transcriptional activity in lipopolysaccharide (LPS)-stimulated macrophages RAW 264.7 with an $IC_{50}$ value of $5.8\;{\mu}M$. The compound was also effective in blocking $NF-{\kappa}B$ transcriptional activities elicited by the expression vector encoding the $NF-{\kappa}B$ p65 or p50 subunits bypassing the inhibitory kB degradation signaling $NF-{\kappa}B$ activation. The macrophages markedly increased their $PGE_2$ and NO production upon exposure to LPS alone. Artemisolide inhibited LPS-induced $PGE_2$ and NO production with $IC_{50}$ values of $8.7\;{\mu}M$ and $6.4\;{\mu}M$, respectively, but also suppressed LPS-induced synthesis of cyclooxygenase (COX)-2 or inducible NO synthase (iNOS). Taken together, artemisolide is a $NF-{\kappa}B$ inhibitor that attenuates LPS-induced production of $PGE_2$ or NO via down-regulation of COX-2 or iNOS expression in macrophages RAW 264.7. Therefore, artemisolide could represent and provide the anti-inflammatory principle associated with the traditional medicine, A. asiatica.

  • Several kinds of medicinal plants are used as diuretics in folk medicines and oriental drugs. The diuretic action of water extracts of the ten kinds of crude drugs, such as Pachyma hoelen $R_{UMPHIUS}$ Zea mays L., Akebia quinata $D_{ECAISNE}$, Alisma orientale Juzepezuk, Atractylodes koreana $N_{AKAI}$, phytolacca americana L., Achyranthes japo-nica $N_{AKAI}$, Juncus decipiens $N_{AKAI}$, Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$ was examined in mouse and compared with aminophylline as a control the following results were obtained. The urine volume was found to be remarkably increased by the Pachyma hoelen RUMPHIUS, Phytolacca americana L., Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$, moderately increased by the Akebia quinata $D_{ECAISNE}$, Achyranthes japonica $N_{AKAI}$ and Juncus decipiens $N_{AKAI}$, and slightly increased by Zea mays $L_{ENNE}$, Alisma orientale $J_{UZFPEZUK}$ and Atractylodes koreana $N_{AKAI}$.

  • Mixed seeds of Dactylis glomerata, Festuca arundinacea, Trifolium repens, Lolium multiflorum on the improved pasture were sown to investigate the vegetational change during the years of 1971-1978. The dominant species were Dactylis glomerata and Trifolium repens from the first year to the third year, Imperata cylindrica and Trifolium repens in the forth year, Imperata cylindria and Zoysia japonica from the fifth year to the eighth year in the pasture.

  • The antimicrobial activity of mugwort(artemisia asiatica Nakai) was investigated. The methanol extract or dried mugwort was fractionated to hexane, chloroform, ethylacetate, butanol, and aqueous fractions. The hexane fraction among these fractions showed the hifhest inhibitory effect on the growth of microorganisms such as Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Lactobacillus plantarum. Bacillus subtilis, Escherchia coli, and Staphylococcus aureus were completely inhibited at a concentration of 250, 500 , and 750$\mu\textrm{g}$/ml respectively. The hexane fraction was further fractionated into 16 subfractions by silica gel column and thin layer chromatography(TLC). The subfraction No. 8, 9, and 10 on TLC exhibited high antimicrnial activity. At 3rd fractionation, subfraction No. 2 inhibited the growth of microorganisms at 500$\mu\textrm{g}$/ml. Heptadecane, dodecamethyi cyclohexasiloxane, (E,E)-2,4-decadienal, dodecamethul pentasiloxane, coumarin, 5,6,6,6a-tetrahydro-4,4,7a-trimethyl-2(4H)-benzofuranone, neophytadiene, tridecanoic acid, methyl ester, 2-methyl-4,5-nonadiene, (Z,Z)-9-12-octadecadienoyl chloride, and bis(2-ethylhexyl) were identified from this antimicrobial fraction by GC-MS.

  • The allelopathic effects of Artemisia lavandulaefolia were studied using several test plants and microbes. Aqueous extracts and volatile compounds of A. lavandulaefolia inhibited seed germination, seedling and root growth of the test species such as Achyranthes japonica. Lactuca sativa, Artemisia princeps var. orientalis. Oenothera odorata, Plantago asiatica. Aster yomena, Elsholtzia ciliata, and Raphanus sativus var. hortensis for. acanthiformis. The root growth of test species was more affected than shoot growth by allelochemicals of A. lavandulaefolia. Essential oil of A. lavandulaefolia had antibacterial and antifungal effects. However, the antimicrobial activity of the essential oil was dependent upon the microbial species and concentrations. Callus growth of Oryza sativa, Brassica campestris subsp. napus var. pekinensis and Achyranthes japonica was sensitive by the essential oil of A. lavandulaefolia. Twenty three chemicals were identified from A. lavandulaefolia essential oil by gas chromatography. Primary allelochemicals among them were 1, 8-cineole, 1-$\alpha$-terpineol, $\alpha$-terpinene. camphor, 2-buten-1-ol and azulene. We concluded that aqueous extract and essential oil of A. lavandulaefolia were responsible for allelopathic effects.
