  • This study was conducted to investigate the effects of addition of Artemisia annua L. powder in jeonbyeong. Contents of crude ash increased as the amount of Artemisia annua L. powder increased, whereas crude fat contents decreased. According to increasing contents of Artemisia annua L. powder, total amino acid contents significantly increased. Hunter's L value increased as contents of Artemisia annua L. powder increased, whereas total free sugar contents decreased. Addition of Artemisia annua L. powder to jeonbyeong increased dietary fiber contents. The sensory score of jeonbyeong containing 100 g of Artemisia annua L. powder was the highest of all jeonbyeong tested. According to the results, addition of Artemisia annua L. powder could improve the quality and sensory characteristics of jeonbyeong.

  • The herb, Artemisia(A) annua, a member of the composital family, has been used successfully for malaria(Plasmodium sp) patients in china. Since the genera of Plasmodium and Eimeria(E) tenella are related, it is presumed that A annua may also be effective against E tenella. In order to study the anticoccidial effects of A annua the chickens inoculated with E tenella were treated with the extract of A annua in drinking water and the results were compared to those of non-medicated, infected control(NIC) and non-medicated, non-infected control(NNC) group. A annua demonstrated anticoccidial effects by showing, compared to NIC group, improved results in all parameters, such as bloody diarrhea, lesion scores, the numbers of excereted oocysts in feces, body weight gain and feed conversion rate. Anticoccidial index(ACI) of the A annua treated group (123.4) was higher than that of NIC group (96.9). These results indicate that Artemisia annua has anticoccidial effects on the Eimeria tenella.

  • Artemisia annua L. (Compositae) is an annual herb, which has been traditionally used as an antipyretic and hemostatic agent with the herbal medicine name of Cheong Ho (菁蒿) in Korea and China. In this study, five di-caffeoylquinic acid derivatives and a coumarin were determined from the hot-water extract of aerial parts of A. annua. The structures of isolates were elucidated to be 1,3-di-O-caffeoylqunic acid (1), 3,4-di-O-caffeoylquinic acid (2), 3,5-di-O-caffeoylqiunic acid (3), 1,5-di-O-caffeoylquinic acid (4) and 4,5-di-O-caffeoylquinic acid (5) and scopoletin (6). The presence of 1,5-di-O-caffeoylquinic acid (4) is firstly reported from A. annua in the current study.

  • The experience of natural dyeing is expected to be effective in promoting health through good exercise, in giving emotional stability based on the functional aromatic components of the dyeing material, and in improving self-esteem and increasing positive experiences through the behavior of creation. A natural dyeing material easily found around us, artemisia has long been used in food and Oriental medicine and was recently found to contain antioxidative, anticancer, deodorizing, antibacterial, anti-obesity, and anti-diabetes substances through chemical analysis. It has also been reported that group reminiscence therapy using the fragrance of artemisia is effective in relieving pain and depression and in promoting ego integrity in the elderly population. This study aimed to make a comparative analysis of dyeability, washing fastness, and deodorization between Artemisia princeps, Artemisia iwayomogi, and Artemisia annua, all of which are considered to be healthful and functional dyeing materials, among about thirty domestic plants in the genus of Artemisia and to provide basic data concerning natural dyeing in mind-peace education for the silver generation. The fabric dyed and post-mordanted at $80^{\circ}C$ for 40 minutes showed the greatest surface color variation; in this condition, artemisia princes (32.29) gave the greatest color difference, followed by artemisia iwayomogi (31.07) and artemisia annua (26.17). While all the types of artemisia were excellent in washing fastness, dry-cleaning fastness, and rubbing fastness at the fourth- or fifth-grade, light fastness was at the third grade for artemisia princes, at the second to third grade for artemisia annua, and at the second grade for artemisia iwayomogi; therefore, artemisia princes was found to give better fastness than the other two types of artemisia. In determining functionality of the fabric dyed with artemisia, deodorization test also found that the fabric dyed with artemisia princes had 20% higher deodorization.

  • The quality characteristics of kimchi with Artemisia annua extracts (1~2%; extracted with water or 70% ethanol), including the pH, acidity, reducing sugar content, total viable cell and lactic acid bacteria cell count, and sensory parameters, were investigated at 10 and $15^{\circ}C$ for 20 days during aging. The pH, acidity, reducing sugar content, and lactic acid bacteria count of kimchi with Artemisia annua extract rapidly increased upto the 4~6th day, increasing slowly thereafter. The quality characteristics did not vary between kimchi with and without the extract. The optimal aging time for kimchi with the extract was 10 days at $10^{\circ}C$. The results of the sensory evaluation showed that kimchi with 1% Artemisia annua extract was superior to kimchi with 2% Artemisia annua extract; in particular, the color and taste of the latter were found to be black and bitter, respectively.

  • In this study, we shortly introduced the HPLC method validation guideline for the analysis of functional food which was released from the Ministry of Food and Drug Safety of Korea in Dec 2018. The HPLC method validation was performed through the aforementioned HPLC method validation guideline in order to quantitate scopoletin content from the hot-water extract powder of Artemisia annua Linné. The HPLC method was validated by evaluating specificity, accuracy, precision, limit of quantitation and linearity. All parameters were in the suitable ranges which are designated in the guideline, which indicated the current HPLC method is reliable to quantitate the scopoletin content from the hot-water extract of A. annua.

  • The antifungal activity of chemical substances from Artemisia annua were examined. Antifungal activity of aqueous extracts from A. annua was higher than that of essential oils in Fusarium oxysporum, whereas that of essential oil was higher than that of aqueous extracts in Aspergillus nidulans. The GC/MS methods were employed for the analysis and identification of phytotoxic substances from A. annua. Essential oil of some components were identified including thujone, terpineol, β-pinene, cienole, 2,4-hexndienal, camphor, citronellal, (-)-menthone, (1R)-(-)myrtenol, (S)-(-)-perilla aldehyde, perilla alcohol, 4-tert-buthylaniline, eugenol, isosafrole, isoeugenol and α-humulene. These results suggest that the chemical substances from A. annua such as terphenoids seem to be responsible for the allelopathic effect.

  • Artemisinin is effective against both chloroquine-resistant and -sensitive strains of Plasmodium species. However, the low yield of artemisinin from cultivated and wild plants is a serious limitation to the commercialization of this drug. Optimization of artemisinin yield either in vivo or in vitro is therefore highly desirable. To this end, we have overexpressed the 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGR) gene (hmgr) from Catharanthus roseus L. in Artemisia annua L. and analyzed its influence on artemisinin content. PCR and Southern blot analyses revealed that the transgenic plants showed stable integration of the foreign hmgr gene. The reverse transcriptase-PCR results suggested that the hmgr was expressed at the transcriptional level in transgenic lines of Artemisia annua L., while the high-performance liquid chromatography analysis showed that artemisinin content was significantly increased in a number of the transgenic lines. Artemisinin content in one of the A. annua transgenic lines was 38.9% higher than that in non-transgenic plants, and HMGR enzyme activity in transgenic A. annua L. was also higher than that in the non-transgenic lines.

  • In order to study the natural preservation of food, sixteen kinds of medicinal plants were extracted by 80% methanol and then antimicrobial activity of the extracts was investigated against various kinds of microorganisms. The extracts of medicinal plants showed good effects of antimicrobial activity against bacteria except Bacillus cereus, Escherichia coli O-157. Especially, the extracts of Artemisia annua, Aster scaber, Solidago virganrea shower good inhibitory effects on the growth of bacteria to the cooling preservation foods, and Artemisia annua was decreased of the TMA(Trimethylamine) test. the result thus indicate that Artemisia annua, Aster scaber, Solidago fischeri extract inhibitory effects on cooling preservation foods, so that it may be potential as a natural preservatives.
