곽향은 서양에서 Korea mint라고 불릴 정도로 허브와 쓰임새가 매우 유사하다. 서양의 허브는 화장품의 소재로 많이 사용하지만 곽향은 우리나라에서 약재로 더 많이 사용되어 화장품 소재로서의 기능 성을 비교해보았다. 곽향 추출물과 추출물을 이용한 유산균과 효모 발효물, 에센셜오일, 플로럴워터에 대한 항산화, 미백, 폴리페놀, 플라보노이드, 항균력 실험을 진행하였다. 항산화 활성은 모든 샘플에서 높은 효과 가 보였고, 미백과 폴리페놀, 항균력에서 에센셜오일이 가장 높은 효과가 보였다. 반면에 플라보노이드는 70% 에탄올 추출물에서 가장 높은 효과가 보였다. 이런 결과로 에센셜오일이 기능적으로 가장 큰 효과가 있었다. 하지만 추출물을 가지고 효모 발효를 진행한 시료들이 에센셜오일 만큼의 효과가 있다는 것을 확 인해 에센셜오일의 적은 추출량에 비해 효모 발효를 진행한 시료가 화장품소재로서 충분한 가치가 있다고 본다.

Potentillae Chinensis Herba 추출물의 항산화 효능 평가를 위해 DPPH 자유라디칼 소거 활성 과 ABTS 양이온 라디칼 활성 평가를 시행하였다. 세포 실험에서 항염증 평가를 위해 호흡기 점막 상피세 포 NCI,H292와 RAW264.7 세포 대상으로 항염증 효능을 평가하였다. 그 결과, DPPH 자유라디칼 소거 활성과 ABTS 양이온 라디칼 활성 모두 농도 의존적으로 항산화 활성이 증가하는 것으로 나타났다. 세포 MTT 분석 결과, 각 농도 100 μg/ml로 처리한 경우 NCI-H292 세포의 생존율이 70% 미만으로 감소하 였고, 이후 실험은 50 μg/ml로 진행하였다. 항염증 효능 평가에서는 NO생성, TNF-α, IL-1β, PGE2가 감소하였고, COX-2도 50 μg/ml에서 유의하게 감소하였다.

Spirodelae Herba (SH) and Perilla Frutescens (PF) extracts have been widely used in clinical practice with various disorders for thousands of years. There are some reports regarding the anticancer effects of SH and PF each by each, but their mixture have not been investigated and their mechanisms also have not been clear. The purpose of the present study was to investigate the anticancer mechanisms and their effects of the mixture of SH and PF extracts on head and neck cancer cell line. Head and neck carcinoma KB cells were treated with SH, PF and their mixture. Anticancer effects were investigated by searching cancer cell death pathway; apoptosis and autophagy, which have been regarded to be effective and safe methods. Apoptosis, which is termed a programmed cell death, was observed by TUNNEL assay. Autophagy, which is termed a type II programmed cell death, was observed by acridine orange red staining. Additionally, the protein expressions associated with apoptosis and autophagy were detected for their mechanism by western blots. The mixture of SH and PF extracts induced autophagic and apoptotic cell death simultaneously in cancer cells. And 0.4 mg/ml of the mixture with SH and PF extracts down-regulated the expression of mTOR, however, the expressions of ATG5 and LC3-II, which induced autophagy, up-regulated. The mixture of SH and PF extracts also down-regulated the expressions of Bcl-2, but up-regulate the expressions of PARP-1 cleavage, Caspase-9 cleavage, Caspase-3 cleavage and BAX, which induced apoptosis. Taken together, these results suggested that the mixture of SH and PF extracts induce autophagic and apoptotic cell death simultaneously in head and neck cancer cells and it could be used as an alternative for anti-cancer drugs.

Glutamate-induced oxidative injury contributes to neuronal degeneration in many central nervous system (CNS) diseases, such as Parkinson’s disease, Alzheimer’s disease, epilepsy and ischemia. Inducible heme oxygenase (HO)-1 acts against oxidants that are thought to play a role in the pathogenesis of these diseases. The EtOH extracts of Viola mandshurica (NNMBS274), Viola patrinii (NNMBS275) and Viola papilionacea Pursh (NNMBS276), origin plants of Violae Herba, showed the potent neuroprotective effects on glutamate-induced neurotoxicity. Among them, NNMBS275, the extract of V. patrinii possessed the protective effects against glutamate toxicity by inducing the expression of heme oxygenase (HO)-1 in the mouse hippocampal HT22 cells. These results suggest that extracts of V. patrinii could be the effective candidates for the treatment of ROS-related neurological diseases. Furthermore, it is suggested that the protective effects of V. patrinii extract due to inducing the expression of HO-1 as an antioxidant/cytoprotective target

In order to fine antioxidant and whitening agent source from nature, the comparisons of antioxidative activity and tyrosinase inhibitory activity were carried out for various ethanol extract on Polygoni Multiflori Radix, Polygonati Rhizoma and Ephedrae Herba. Comparing for three ethanol extracts, the highest electron donating ability was found at Polygonati Rhizoma (86.6%), but, the highest SOD-like ability, at the Ephedrae Herba (47.8%). Xanthine oxidase experiment exhibited 95.7% of hindrance effect in Ephedrae Herba, and 84.0% in Polygonati Rhizoma. A tyrosinase inhibitory activity assay was conducted to evaluate the whitening effects of the extracts, The tyrosinase inhibitory activity was 6.5% in the Polygoni Multiflori Radix, 32.6% in the Polygonati Rhizoma, 64.0% in the Ephedrae Herba. Based on these results, we suggest that the ethanol extracts of Polygoni Multiflori Radix, Polygonati Rhizoma and Ephedrae Herba can be used as food and cosmetic ingredients.

This study was performed to elucidate the effects of Epimedii Herba on the antibody responses in mice immunized by Ovalbumin (OVA). Antibodies in serum were detected in male ICR mice treated with the aqueous extract of Epimedii Herba at a dosage of 40, 120, and 360 mg/kg orally for 2 weeks. Effects of AEEH on antibody forming responses were measured by enzyme linked immunosorbent assay (ELISA) of immunoglobulin (Ig) levels in serum collected 7 days after priming with OVA in complete Freund,s adjuvant (CFA). The results were as follows; 1. Epimedii Herba slightly decreased body weight gain. 2. Epimedii Herba significantly increased the relative spleen weight. 3. Epimedii Herba significantly increased total serum IgG levels. 4. Epimedii Herba significantly enhanced total serum IgG1 levels. 5. Epimedii Herba significantly increased total serum IgG2a levels. 6. Epimedii Herba markedly increased total serum IgM levels. These findings demonstrate that Epimedii Herba significantly enhances serum antibody production after priming with OVA in CFA, and suggest that Epimedii Herba may prevent the host from microbial infections.

The essential oil obtained by steam distillation from medicinal plants of Cinnamomum cassia and Prunellae Herba. Analysis of essential oils were performed on GC/MS selective detector.

Ten volatile flavor components were identified from C. cassia and ten volatile flavor components were identified from Prunellae Herba. Strong inhibition of growth of Vibrio parahaemolyticus was obtained with all doses of C. cassia tested. Moreover, antimicrobial activity of C. cassia occurred in a dose dependant manner.

Collected germplasms of five representative dandelion species (Taraxacum ohwianum, T. platycarpum, T. platypecidum, T. officinale, and T. coreanum) were 104 lines from different habitates in Korea and China. Their genetic diversity was analyzed by genomic fingerprinting method using amplified fragment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 1,176 total DNA fragments and 523 polymorphic bands with a 44.4% ratio of polymorphism. On the basis of similarity coefficient analysis by unweight pair group method with arithmetic averages (UPGMA), 104 dandelion germplasm lines were ranged from 0.64 to 0.99 and clustered distinct five group depending on the species. Furthermore, a principal coordinate analysis (PCA) by the application of multi-variate analysis indicated significantly greater differences among species than geographical origins.
