본 연구는 박하 추출물을 통해 독성검사 및 항산화, 항염증과 같은 생리활성을 평가하고자 하였다. 박하 추출은 열수 및 80% 에탄올로 추출하였으며, RAW 264.7 세포를 통해 MTT를 통해 세포 생존율을 평가하였다. 또한, LPS로 유도한 RAW 264.7 세포를 통해 활성산소(ROS), 산화질소(NO), 류코트리엔 B4($LTB_4$), 항염 또는 염증성 사이토카인($IL-1{\beta}$, IL-6, $TNF-{\alpha}$, IL-10) 등을 ELISA 및 Luminex로 측정하였다. 그 결과, 박하 추출물은 열수 및 80% 에탄올 추출물에서 세포독성이 없었으며, 80% 에탄올 추출물의 $100{\mu}g/m{\ell}$ 농도에서 활성산소의 생성을 억제하였다. 또한, NO, LTB4, 염증 또는 항염증성 사이토카인의 생성을 모든 추출물에서 농도 의존적 효능을 나타냈다. 즉, 박하 추출물은 세포독성 없이 항산화 및 항염증 활성을 나타내는 생리학적 효능이 나타났다. 이와 같은 결과는 본 연구와 관련된 증상을 개선하기 위한 새로운 건강식품 및 치료제의 원료로 개발될 수 있다.

Cervical cancer is one of the leading causes of female death. Viral oncoproteins E6 and E7 are selectively retained and expressed in carcinoma cells infected with HPV (Human pa pilloma virus) type 16 and cooperated in immotalization and transformation of primary keratinocyte. E6 and E7 oncoproteins interfere the functions of tumor suppressor proteins p53 and retinoblasoma protein (pRb), respectively. Among a lots of natural products, Mentha arvensis Linne var.piperascens have inhibitory effects on bindings between E6 oncoprotein and tumor suppressor p53, E3 ubiqutin- protein ligase (E6AP). HPV oncoprotein inhibitors from Mentha piperita L. were isolated by solvent partition and column chromatography (Silica gel, RP-18) and inhibitory compounds were finally purified by HPLC using an ELISA screening system based on binding between E6 and E6AP. The aim of this study is to identify the structure of inhibitory compounds and to investigate whether these compounds have inhibitory effects on functions of E6 oncoprotein. We investigated whether caffeic acid methyl ester (CAM) extracted from Mentha piperita L. could inhibit the function of E6 oncoprotein. CAM inhibited the in vitro binding of E6 and E6AP which are essential for the binding and degradation of the tumor suppressor p53 and also inhibited the proliferation of human cervical cancer cell lines (SiHa and CaSKi) in a dose response manner. These results suggest that CAM inhibited the function of E6 oncoprotein, suggesting that it can be used as a potential drug for the treatment of cervical cancers infected with HPV.

Objectives : Reactive oxygen species (ROS) are involved in a wide spectrum of diseases including chronic inflammation and cancer. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the extracts from the herbal teas such as Lonicera japonica Thunberg (L. japonica), Chrysanthemum morifolium Ramat (C. morifolium), Mentha arvensis L. (M. arvensis), and P.rhizoma. Methods : Anti-oxidant activity was evaluated using DPPH radical scavenging assay and $Fe^{2+}$ chelating assay. And DNA cleavage assay was performed to evaluate an anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell line. Results : L. japonica scavenged DPPH radical by 9.8% at 12.5 ${\mu}g/ml$, 24.8% at 25 ${\mu}g/ml$, 34.3% at 50 ${\mu}g/ml$, 61.1% at 100 ${\mu}g/ml$ and 75.8% at 200 ${\mu}g/ml$, respectively. In addition, C. morifolium and M. arvensis removed DPPH radical by 15.6% and 10.4% at 12.5 ${\mu}g/ml$, 34.8% and 22.8% at 25 ${\mu}g/ml$, 66.9% and 43.3% at 50 ${\mu}g/ml$, 87.4% and 69.1% at 100 ${\mu}g/ml$, and 92.1% and 73.2% at 200 ${\mu}g/ml$, respectively. However, P. rhizoma did not affect on DPPH radical scavenging. The $Fe^{2+}$ chelating activity was highest in L. japonica, but lowest in P. rhizoma among the herbal teas. In addition, the extracts from L. japonica, C. morifolium and M. arvensis inhibited oxidative DNA damage via its anti-oxidant activity. In anti-inflammatory effect, the extracts from C. morifolium inhibited NO production. In addition, it suppressed the $NF-{\kappa}B$ signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, this study indicates that L. japonica, M. arvensis and C. morifolium possess the protective effect against the oxidative DNA damage. Furthermore, C. morifolium exerts an anti-inflammatory effect.

Objectives : The purpose of this study was to investigate the interpretation of the Soyo-san(SYS) prescription in order to obtain the evidence for clinical applications. Methods and Result : We interpreted on the SYS-related contents based on 25 classic books, analyzed it according to followed categories ; meaning of name, alteration of herbal composition according to age, usage, origin, physiological and pathological situation of SYS, description of each herbal drug Conclusion : 1. So(逍) mean diminish(消), 遙 mean roll(搖). It reflected feature of SYS, that alleviate depression without impairing vital energy(正氣). 2. SYS was first mentioned in the prescription of peaceful benevolent dispensary(太平惠民和劑局方), its essential application was harminizing liver depression and spleen deficiency(肝鬱脾虛) 3. SYS originated from Sayuk-san. Sayuk-san was appropriate for soothe the liver and regulate the spleen(疏肝理脾), while SYS was suitable for depressed liver and blood deficiency(肝鬱血虛) 4. Most medical literature insisted that application situation of SYS is blood deficiency(血虛), depressed liver(肝鬱), spleen deficiency(脾虛). And there is strong correlation between three factors. 5. Bupleurum falcatum L.(柴胡), Mentha arvensis L.(薄荷) alleviates liver depression as "pungent dissipate-qi uprais (辛散氣升)" nature. Angelica gigas Nakai(當歸), Paeonia lactiflora Pall.(白芍藥) emoliates the liver by nourishing the blood. Atractylodes japonica Koidz. ex Kitam.(白朮), Poria cocos(茯苓), Glycyrrhiza uralensis Fisch.(甘草), Zingiber officinale Roscoe(生薑) cultivate the basis as tonifying earth(補土).

Obesity is a major risk factor for various metabolic diseases such as cardiovascular disease, hypertension, and type 2 diabetes mellitus. In this study, we prepared ethanol extracts from Agastache rugosa (ARE), Chrysanthemum zawadskii (CZE), Mentha arvensis (MAE), Perilla frutescens (PFE), Leonurus sibiricus (LSE), Gardenia jasminoides (GJE), and Lycopus coreanus (LCE). The anti-oxidant and anti-adipogenic effects were evaluated. The $IC_{50}$ values for ascorbic acid and LCE against 2,2-diphenyl-1-picrylhydrazyl radicals were $246.2{\mu}g/mL$ and $166.2{\mu}g/mL$, respectively, followed by ARE ($186.6{\mu}g/mL$), CZE ($198.6{\mu}g/mL$), MAE ($337.1{\mu}g/mL$), PFE ($415.3{\mu}g/mL$), LSE ($548.2{\mu}g/mL$), and GJE ($626.3{\mu}g/mL$). In non-toxic concentration ranges, CZE had a strong inhibitory effect against 3T3-L1 adipogenes (84.5%) than those of the other extracts. Furthermore, the anti-adipogenic effect of CZE is largely limited in the early stage of adipogenesis, and we revealed that the inhibitory role of CZE in adipogenesis is required for the activation of Wnt signaling. Our results provide scientific evidence that the anti-adipogenic effect of CZE can be applied as an ingredient for the development of functional foods and nutri-cosmetics for obesity prevention.

BACKGROUND: Herbal extracts have been screened for their inhibitory effect of seed germination and root development on weeds, but there is a scarcity of reports for crop growth regulation. The objective of this research was to develop a growth inhibitor on Brassica campestris, and its effective extraction method from herbal medicine extract. METHODS AND RESULTS: Eighty four herbal medicine extracts were tested for their plant growth inhibition activity on B. campestris. The alcohol extracts of Artemisia annua, Cinnamomum cassia, and Mentha arvensis inhibited over 30% of germination and the extract of A. annua, and C. cassia inhibited over 70% of radicle growth at 0.1 % w/w treatment. The partially purified extracts of A. annua, and C. cassia with dichloromethane and hexane showed stronger radicle growth inhibition than the crude extracts on B. campestris. The diethyl ether extract of A. annua showed a similar 50% radicle growth inhibition ($RI_{50}$ = 45 mg/L) to its partially purified extract with dichloromethane or hexane, but the diethyl ether extract of C. cassia showed a worse $RI_{50}$ than the purified extract. CONCLUSION: The alcohol extracts of A. annua, and C. cassia showed potent radicle growth inhibition properties on B. campestris. Diethyl ether proved to be a good solvent for simple extraction from A. annua.
