본 연구는 섬애약쑥(Artemisia argyi H.)의 항가려움증 활성 가능성을 확인하기 위한 연구로써 가려움증 관련인자 등을 측정하였다. 섬애약쑥은 열수로 추출(Artemisia argyi H. distilled water extract 이하, AAD)하여 MTT assay로 세포독성을 측정하였고 항 가려움증 활성을 확인하기 위하여 IL-4와 IL-31 관련 전사인자 발현 및 단백질 생성을 측정하였으며, 히스타민의 발현을 측정하였다. 그 결과 25, 50, 100 ㎍/㎖의 농도에서는 유의한 세포독성이 나타나지 않는 것을 확인하였다. 가려움증 연관 유전인자인 IL4의 경우 25 ㎍/㎖의 농도에서 약 12%, 50 ㎍/㎖의 농도에서 약 26%, 100 ㎍/㎖의 농도에서 약 61%로 유의하게 감소하였으며, IL31의 경우 50 ㎍/㎖의 농도에서 약 33%, 100 ㎍/㎖의 농도에서 약 33% 로 유의하게 감소하였다. 연관된 단백질 측정의 경우 각각 50 ㎍/㎖와 100 ㎍/㎖의 농도에서 IL-4는 약 34% 및 약 69%, IL-31은 약 36% 및 약 37% 유의하게 감소하였다. 이 결과는 ADD가 항가려움증을 위한 소재로써 가능성을 보여 소재 개발을 위한 기초자료로 제공될 수 있을 것으로 사료된다. The purpose of this study was to investigate the anti-pruritic activities such as cell viability and pruritus-related factor using seomaeyakssuk (Artemisia argyi H.; Seomaeyakssuk) extract on MC/9 (mouse mast cell line). Seomaeyakssuk was extracted from hot distilled water. Cell viability was assessed using MTT assay on MC/9 cells. Anti-pruritic activities were measured through changes in the levels of transcription factor (IL4 and IL31) on MC/9 cells. In addition, the expression of linked proteins and histamine was measured. The results confirmed that significant cytotoxicity does not appear in the concentration range of 25, 50, and 100 ㎍/㎖. The levels of IL4 was reduced to 12% (25 ㎍/㎖), 26% (50 ㎍/㎖) and 61% (100 ㎍/㎖). Also, level of IL31 was decreased 33% (50 ㎍/㎖) and 36% (100 ㎍/㎖). In the case of proteins levels decreased significantly IL-4 34%/69% and IL-31 36%/37% at 50 ㎍/㎖ and 100 ㎍/㎖. Histamine decreased by 22, 58% and 61%, respectively, at concentrations of 25, 50, and 100 ㎍/㎖. This results shows possibility of ADD as raw material in anti-pruritic products.

본 연구는 섬애약쑥(Artemisia argyi H.)의 미백활성을 평가하였다. 섬애약쑥은 증류수와 70% 에탄올로 추출하였으며, 세포에서의 독성평가로 안전함을 확인하였다. 미백활성은 세포내 티로시나아제, 세포외 티로시나아제, 멜라닌 합성저해 및 미백관련 전사인자 감소로 평가하였다.그 결과 50, 100, 200 ㎍/ ㎖에서 유의한 세포독성이 나타나지 않는 것을 확인하였다. 각 시료의 200 ㎍/㎖ 농도에서 세포 외 멜라닌 생성량의 경우 AAD 45.0%로 유의하게 감소되었으나 AAE는 1.3%로 미미하게 감소되었으며, 세포 내 멜라닌 생성량의 경우 AAD 37.2%, AAE 24.6% 감소되었다. 세포 내 tyrosinase 활성의 경우 200 ㎍/㎖ 농도에서 AAD 49.2%, AAE는 35.6% 감소되었다. 또한 tyrosinase, TRP-1, TRP-2 전사인자 각각은 AAD 63.0%/AAE 58.0%, AAD 60.0%/AAE 56.0%, AAD 59.0%/AAE 53.0%로 감소되었다. 추출물 모두 미백 활성에 효과가 있었으나 상대적으로 AAD가 AAE에 비하여 미백효능이 높은 것으로 확인되었다. 향 후 미백 기능성화장품의 원료로써 응용 가능성이 높을 것으로 사료된다. This study investigated the whitening activity using seomaeyakssuk (Artemisia argyi H.) extract. Seomaeyakssuk was extracted from hot DW (AAD) and 70% ethanol (AAE). And confirmed safety through assessment of cytotoxicity. Also, whitening activities were measured through changes in the levels of extracellular melanin, melanin synthesis, cellular tyrosinase activity and transcription factor. The results confirmed that significant cytotoxicity does not appear in the concentration range of 50, 100, and 200 ㎍/㎖ of both extracts of this study. The production of extracellular melanin was slowed by AAD 45.0% and AAE 1.3% at 200 ㎍/㎖ concentration. Also, production of intracellular melanin was decreased AAD 37.2% and AAE 24.6%. In the case of intra cellular tyrosinase activity was reduced to AAD 49.2% and AAE 35.6% at 200 ㎍/㎖ concentration. The mRNA expression of tyrosinase, TRP-1 and TRP-2 significantly decreased by AAD 63.0%/AAE 58.0%, AAD 60.0%/AAE 56.0% and AAD 59.0%/AAE 53.0%, respectively, following the 200 ㎍/㎖ sample treatment when compared to the control. Both extracts showed efficient changes of production of whitening-related factor and transcription factor. But AAD was found to have a higher inhibitory effect than AAE. In other words, seomaeyakssuk was showed significant biological activities showing whitening without cytotoxicity. These results will be provided as fundamental data for further development of the new material of functional cosmetics to the results above.

In this study, we investigated the antioxidant activities using lemongrass and maychang essential oils purchased from Neumond (Germany). Component of oils were analyzed using GC/mass chromatography. ABTS and DPPH radical scavenging activities of each oil were measured at concentration of 0.01 μL/mL, 0.1 μL/mL, 1 μL/mL, 10 μL/mL and 100 μL/mL. Also we measured SOD activity of lemongrass oil and maychang oil. In addition, we measured the levels of ROS and NO on LPS-induced Raw 264.7 cells. The ABTS radical scavenging activity was higher for lemongrass oil than for maychang oil. Lemongrass oil showed a relatively higher outcome in terms of DPPH radical scavenging activity. Maychang oil has a higher SOD-like activity than lemongrass oil. In addition, lemongrass oil and maychang oil effectively suppressed NO production. Also, maychang oil were higher than those of lemongrass oil on levels of ROS. Lemongrass oil and maychang oil showed significant antioxidant activity. These results indicated that lemongrass oil and maychang oil had high potential for antioxidative activities and deserved to be developed into new therapeutics.

Objectives: The aim of this study is to investigate cell viability, anti-inflammatory, antioxidant, immunoenhancing activity using various extracts of Yeonsan Ogye. Methods: In order to evaluate cytotoxicity, MTT assay was performed. We investigated production levels of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α and interleukin (IL)-6, and nitric oxide(NO) in LPS-induced RAW 264.7 cells. NO production in RAW 264.7 cells was measured by using Griess reagent. Cytokines including IL-6 and TNF-α were measured by Luminex and ROS was measured by Flow cytometry. Results: No cytotoxicity of various extracts of Yeonsan Ogye was observed in RAW 264.7 cells. Productions of ROS in RAW 264.7 cells were increased from extraction of bones and decreased from extraction of skin. Also, productions of NO in RAW 264.7 cells were increased to bone extract and decreased at skin extract. In addition, productions of pro-inflammatory cytokines (IL-6 and TNF-α) in LPS-induced RAW 264.7 cells were decreased at skin, meat extracts, respectively. Finally, the levels of immune-related cytokines (IL-6 and TNF-α) were increased compared to those of the normal group. Conclusions: It is concluded that Yeonsan Ogye extracts seem to have significant biological activities likes anti-inflammatory, antioxidant, immuno-enhancing etc. These results may be developed as a raw material for new health food and new therapeutics to ease the symptoms related with inflammatory and oxidative stress. In terms of oriental traditional medicine, we expect that it contribute to building of EBM (Evidence-Based Medicine) from the this result.

본 연구는 국내에서 재배한 어성초를 각기 다른 조건에서 저장한 후 어성초의 추출액을 이용한 천연 화장품 소재로서의 타당성을 분석하였다. quercetin 의 함량은 건 어성초보다 생 어성초에서 더 높았으며;총 폴리페놀 함량과 총 플라보노이드 함량을 측정한 결과 건 어성초가 생 어성초에 비해 상대적으로 높은 함량으로 분석되었으나 DPPH 및 ABTS 라디칼 소거 활성은 생 어성초가 상대적으로 높은 결과를 보였다. ROS 소거능과 산화질소 생성 억제율은 생 어성초에서 높은 억제율을 보였으나 100 ㎍/mL의 농도에서 건 어성초가 산화질소를 더 감소시키는 것으로 나타났다. 염증성 사이토카인의 감소를 측정한 결과 IL-1β는 건 어성초가 비교적 높은 감소 효과가 나타났고;IL-6와 TNF-α는 생 어성초에서 높은 감소 효과를 나타냈다. 이상의 결과로부터 생 어성초는 초기 염증 반응에 효과적이며 건 어성초는 염증이 만성 단계로 악화하는 것을 예방하는데 효과적인 것으로 예상된다. In this study;Korean-cultivated Houttuynia cordata Thunb. (HC) was extracted anti-inflammatory effects of extracts were compared in order to confirm the possibility of natural cosmetics as a raw material. HPLC pattern analysis;cell viability assay;total phenolic contents;ABTS/DPPH radical scavenging analysis;measurement of ROS production;griess reagent assay;and luminex technique. The content of quercetin was higher in fresh Houttuynia cordata (HC-F) than in dried Houttuynia cordata (HC-D). Also;content of HC extracts shows a difference in the content of the two representative compounds (polyphenol and flavonoid) according to the stored differently. ROS production showed higher inhibitory rates at HC-F. The anti-inflammatory activity of HC-D was shown higher than that of HC-F. But;in the measurement of the reduction in inflammatory cytokines;IL-1β showed that HC-D had a relatively high reduction effect;and IL-6 and TNF-α showed a high reduction effect. And these results will be a basis for the development of cosmetology in skin care and improvement of skin problem.
