  • 사철쑥에 함유되어 있는 천연 화학물질이 다른 식물에 미치는 효과를 구명하기 위하여 실험식물의 종자발아와 생장실험을 수행하고 사철쑥의 화학성분을 분석했으며, 그 성분과 동일한 시약으로 생물학적 정량을 실시하였다. 사철쑥의 수용추출액에 의한 발아율은 실새풀, 이고들빼기와 왕고들빼기는 수용추출액의 농도가 증가함에 따라 비례적으로 감소했으나, 그러나 코스모스와 익모초는 70% 실험구와 100%, 10%구와 30%에서 서로 반대로 나타났다. 유식물의 건중량은 추출액의 농도가 증가함에 따라 감소현상이 뚜렷하였다. 사철쑥의 정유의 농도에 따라 쑥과 질경이는 정유농도가 증가함에 따라 생장은 억제되었고 유근보다 유묘에서 더욱 확실하였다. GC로 사철쑥의 정유를 분석하여 36종류의 화학물질을 분리확인하였고 이들중 7종류를 선정하여 생물학적 정량을 실시한 결과 terpinen-4-ol이 가장 강한 억제작용이 있었다.

  • Melanogenesis is induced mainly by ultraviolet radiation of sunlight and ${\alpha}$-Melanocyte stimulation hormone (${\alpha}$-MSH) which binds to a specific G protein coupled receptor. ${\alpha}$-MSH and cAMP-elevating agents are known to melanin syntheisis and dendrite outgrowth. The purpose of this study was to investigate the mechanism of melanogenesis inhibition in B16/F10 cells by ethanol extract of Artemisiae Capillaris Herba. In the present study, ${\alpha}$-MSH led to a stimulation of melanin synthesis that appeared to result from an increased tyrosinase activity and melanin content. However, the ethanol extract of Artemisiae Capillaris Herba inhibited the ${\alpha}$-MSH-induced tyrosinase activity and melanin content. In control conditions, B16/F10 cells displayed a fibroblastic appearance while ${\alpha}$-MSH treatment promoted the emergence of small and numerous dendrites from the plasma membrane. The ethanol extract of Artemisiae Capillaris Herba abolished the ${\alpha}$-MSH-induced dendricity. Regarding protein levels of the melanogenic enzymes, the amounts of tyrosinase were increased after incubation with ${\alpha}$-MSH. The treatment of Artemisiae Capillaris Herba ethanol extract decreased the ${\alpha}$-MSH expression levels of tyrosinase. Based on these findings, it is likely that the ethanol extract of Artemisiae Capillaris Herba exerts its depigmenting effects in B16/F10 cells through the suppression of tyrosinase expression, which are key enzymes for melanogenesis.

  • 사철쑥 (Artemisia capillaris Thunberg)이 암세포의 세포고사에 미치는 영향을 보기 위하여 인체 자국경부 상피암 세포주인 HeLa 세포를 이용하여 사철쑥의 메탄올, 에틸아세테이트, 부탄올 추출물의 농도를 각각 0, 100, 500, 1,000 및 $2,000{\mu}g/ml$로 처리하여 세포활성도, 세포형태 변화, DNA분절, DNA 함량을 알아보았다. 세포활성도는 사철쑥의 메탄올, 에틸아세테이트 추출물이 농도에 비례하여 HeLa세포생존율을 감소시켰지만 부탄올 추출물에서는 그 정도가 약하였고 물 추출물에서는 거의 관찰되지 않았다. 사철쑥의 메탄올, 에틸아세테이트, 부탄올과 물 추출물은 각 추출물의 농도에 의존적으로 배양된 HeLa 세포에 세포부착을 방해하고 세포막의 blobbing 및 핵의 분절화 등 세포고사의 특징들을 나타냈다. 사다리형 DNA 분절현상은 사철쑥의 메탄올 추출물 $1,000{\mu}g/ml$, $2,000{\mu}g/ml$ 처리군에서 관찰되었다. 유세포분석기 (FACS)를 이용하여 측정한 고사세포의 DNA 함량은 메탄올과 에틸아세테이트, 부탄올 추출물이 농도 의존적으로 증가하였다. 이상의 결과는 사철쑥이 암세포의 세포고사를 증가시킴으로서 암 억제 작용이 있을 것을 시사해 준다고 할 수 있다.

  • In this study, changes in the volatile compounds of Artemisia capillaris essential oil were investigated under six different storage conditions for 6 months. The essential oil was collected by steam distillation and analyzed by a gas chromatography-mass selective detector (GC-MSD). Seventy-five volatile compounds were identified from the fresh essential oil of Artemisia capillaris. During storage, the total levels of aldehydes, alcohols, and ketones slightly decreased and the level of hydrocarbons greatly decreased; the total level of esters also decreased in the essential oil. Notably, the levels of carvacrol, eugenol, myrcene, 1,8-cineole, caryophyllene, coumarin, ${\alpha}-thujone$, ${\beta}-thujone$, borneol, and ${\gamma}-terpinene$, known as antioxidants and antimicrobial agents, decreased during storage. Finally, aerobic storage conditions caused greater reductions in some compounds even at low temperatures.

  • Genus Artemisia occurs as a hardy plant and has a wide range of culinary and medicinal features. In this study, we aimed to describe the melanin inhibitory activity of one Artemisia species, i.e., Artemisia capillaris Thunb. Ethanol extracts of fermented Artemisia capillaris (Art.EtOH.FT) and non-fermented Artemisia capillaris (Art.EtOH.CT) were tested for their ability to inhibit tyrosinase activity and melanin pigmentation. Both extracts showed dose-dependent inhibition against ${\alpha}$-melanocyte stimulating hormone-stimulated melanin formation and tyrosinase activity, without cytotoxicity. At $100{\mu}g/mL$, both extracts showed greater inhibition than kojic acid, the positive control. Protein expressions of microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), tyrosinase-related protein 1 (TRP-1), and tyrosinase-related protein 2 (TRP-2) at the transcriptional level were determined by using real-time and semi-quantitative polymerase chain reaction. To complete the mechanistic study, presences of upstream elements of MITF, the phosphorylated-extracellular signal-regulated kinase (p-ERK), and phosphorylated-mitogen-activated protein kinase kinase (p-MEK) were confirmed by using western blot analysis. Expressions of p-TYR, p-TRP-1 and p-TRP-2, downstream factors for p-ERK and p-MITF, were translationally inhibited by both extracts. Art.EtOH.FT induced more potent effects than Art.EtOH.CT, especially signal transduction effects. In summary, Artemisia capillaris extracts appear to act as potent hypopigmentation agents.

  • Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and the most common plant among the various herbal folk remedies used in treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. In this study, antimicrobial effects of Artemisia capillaris extracts on the food poisoning bacteria were investigated for further clinical application, which is an alternative for the use of antibiotics and their unexpected resistance. Artemisia capillaris extract using ethyl acetate showed the highest antimicrobial effects on S. enteritidis, E. coli O157 : H7, L. monocytogenes and S. aureus. The chloroform extract showed strong effects on all kinds of bacteria; whereas ethanol and methanol extracts showed weaker effects. Finally, ether and water extracts showed the weakest effects under the same conditions. The minimum inhibitory concentration (MIC) of ethyl acetate extract was 1 mg/mL for E. coli O157 : H7 and L. monocytogenes, and 2 mg/mL for S. enteritidis and S. aureus. The inhibitory effects on all the bacteria continued for 12 hours after incubation using 20 mg/mL and 30 mg/mL of ethyl acetate extract. The inhibitory effects continued maximally for 72 hours. The results of these studies indicate Artemisia capillaris extract exhibited excellent antimicrobial and inhibitory effects on the food poisoning pathogenic bacteria; S. enteritidis, E. coli O157 : H7, L. monocytogenes and S. aureus.

  • The host immune system is the first line of host defense, consisting mainly of innate and adaptive immunity. Immunity must be maintained, orchestrated, and harmonized, since overactivation of immune responses can lead to inflammation and autoimmune diseases, while immune deficiency can lead to infectious diseases. We investigated the regulation of innate and adaptive immune cell activation by Artemisia capillaris and its components (ursolic acid, hyperoside, scopoletin, and scopolin). Macrophage phagocytic activity was determined using fluorescently labeled Escherichia coli, as an indicator of innate immune activation. Concanavalin A (ConA)- and lipopolysaccharide (LPS)-induced splenocyte proliferation was analyzed as surrogate markers for cellular and humoral adaptive immunity, respectively. Neither A. capillaris water extract (WAC) nor ethanol extract (EAC) greatly inhibited macrophage phagocytic activity. In contrast, WAC suppressed ConA- and LPS-induced proliferation of primary mouse splenocytes in a dose-dependent manner. Similarly, EAC inhibited ConA- and LPS-induced splenocyte proliferation. Oral administration of WAC in mice decreased ConA- and LPS-induced splenocyte proliferation, while that of EAC suppressed LPS-induced splenocyte proliferation. Repeated administration of WAC in mice inhibited ConA- and LPS-induced splenocyte proliferation. Ursolic acid, scopoletin, and scopolin reduced ConA- and LPS-induced primary mouse splenocyte proliferation, while hyperoside did not show such activity. These results indicate that A. capillaris and its components, ursolic acid, scopoletin, and scopolin, suppress ConA- and LPS-induced adaptive immune cell activation. The results suggest that A. capillaris is useful as a regulator of adaptive immunity for diseases involving excessive immune response activation.
