안전한 천연물을 이용한 천연항산화제 개발 연구에 대한 관심이 고조되는 가운데, 지유, 진피, 천련자, 천문동, 청피, 편축, 하고초 7종의 천연 약용식물 추출물을 통해 항산화 활성을 측정하였다. 추출물의 총 페놀 함량은 지유가 열수추출물과 40% ethanol 추출물에서 각각 31.5 mg/g, 32.7 mg/g으로 가장 높게 나타났다. 추출물의 수용성 물질에 대한 항산화 효과는 DPPH radical 소거능이 지유, 진피, 천련자, 천문동, 청피, 편축, 하고초 7종의 천연 약용식물의 열수 추출물과 ethanol 추출물에서 80% 이상의 높은 소거활성을 나타내었다. ABTS radical cation decolorization을 측정한 결과, 7종의 천연 약용식물의 열수 추출물과 ethanol 추출물에서 85% 이상의 높은 저해율을 나타내어 매우 우수한 항산화 효과를 가지고 있음을 입증하였다. 지용성 물질에 대한 항산화 효과를 측정하기 위해 Antioxidant Protection Factor(PF)를 측정한 결과, 천련자 열수 추출물에서 1.65 PF로 대조구인 vitamin C 보다 높은 수준을 나타내어 지용성 물질에 대한 항산화 활성이 높음을 확인하였다. TBARs 생성 저해율을 측정한 결과 지유, 천련자, 청피, 편축, 하고초의 열수 추출물과 ethanol 추출물에서 99%에 가까운 높은 저해율을 나타내어 대조구인 vitamin C보다 지용성 물질에 대한 항산화 활성이 매우 높은 것으로 확인되었다.

감귤은 국내 및 동남아시아 지역에서 많이 즐기는 식품 중 하나이며, 이러한 감귤류의 껍질을 건조시킨 것을 진피라고 한다. 이러한 진피는 한방에서는 이뇨작용, 비장기능을 강화하는 것으로 알려져 있으나, 천연 플라보노이드를 다량 함유하고 있어 학계에서 여러 분야로 연구가 되고 있는 실정이다. 본 연구에서는 플라보노이드 배당체를 함유한 진피 추출물을 ${\beta}$-glucosidase 효소를 이용하여 아글리콘(aglycone)으로 변환 할 수 있도록 치마버섯 배양을 실시하였다. 진피 발효 배양액을 HPLC를 이용하여 분석하였으며, UVA에 의한 광손상 보호능을 섬유아세포를 이용하여 측정하였다. 진피 발효 배양액은 COX-2, LOX-5와 같은 항염증 관련 대사에도 관여하여 염증완화에도 도움을 줄 수 있음을 확인하였다. 또한 각질 형성세포를 이용한 interleukin-$1{\alpha}$를 측정한 결과 진피발효배양액 처리군의 저해활성이 더 높았다. 이러한 결과로 미루어 볼 때, 진피발효 배양액은 피부에 대한 항염 및 항산화 효과가 우수한 것으로 사료된다.

Objectives: Excessive melanin production leads to skin pigmentation, which causes various cosmetic and health problems. Citrus unshiu Markovich peel (CS) and Cimicifuga dahurica (CD) have long been widely used as a oriental medicinal plant because of their pharmacological properties including anti-ulcer, anti-oxidant, and anti-inflammatory properties. Methods: In this study, we investigated the inhibitory effects of CS, CD extracts or CS:CD=1:2 mixture on melanogenesis according to the various extraction methods. CS and CD extracted were prepared by ethanol extraction (EE), ultrasonification extraction (USE), Supercritical extraction (SCE), reflux extraction (RE), respectively. Results: DPPH radical scavenging and tyrosinase inhibitory activity of CD extracts or CS:CD=1:2 mixture were increased in dose-dependent manners. In addition, we evaluated the effect of CS, CD extracts or CS:CD=1:2 mixture on tyrosinase activity and melanogenesis in α-melanocyte stimulating hormone-induced B16-F10 melanoma cells. CS, CD extracts or CS:CD=1:2 mixture significantly inhibited tyrosinase activity and melanogenesis at 10-200 ㎍/mL. Conclusions: Therefore, our study suggests that CS and CD extracts have potential as a safe treatment for excessive pigmentation or as a natural ingredient in cosmetics.

Objectives : The present study was undertaken to determine whether the ethanol extact of Citri Pericarpium (CP, Pericarp of Citrus unshiu Markovich, Rutaceae) is effective against atopic dermatitis according to it's storage period. Methods : To evaluate antiallergic effect of CP and OCP (Old Citri Pericarpium) evaluated in vivo their inhibitory effects against passive cutaenous anaphylaxis (PCA) reaction induced by IgE-antigen complex and scratching behaviors by compound 48/80. The Anti-atopic effects were measured by contact dermatitis, prurient animal model and PCA reaction. Contact dermatitis in mice as a model of the Type IV reaction caused by Oxazolone. Results : The results showed that anti-pruritus effects, analgesic effects of CP was depends on its hesperetin contents. And It also showed that keep longer in storage appeared to be higher in hesperetin contents. Both CP and OCP(Old CP) have a dose-dependent analgesic action in acetic acid induced writhing syndrome. OCP Potently inhibited PCA reaction in mice, although OCP weakly inhibited in long term contact dermatitis model in mice. Conclusions : These results suggest that the Proportional to the storage period, Citri Pericarpium possesses analgesic effects and anti-allergic effects.

Objectives: The purpose of this review is to anaylze the domestic study trends of Korean medicine treatment for hyperemesis gravidarum. Methods: We investigated the studies on Korean medicine treatment on hyperemesis gravidarum via searching four online databases up to October 2021. After searching studies, we analyzed selected studies. Results: 13 clinical studies were selected and all studies were case reports. The most common Korean Medicine used in hyperemesis gravidarum were Boseng-tang -gamibang, Gyullyeongboseng-tang, Taesanbanseok-san-gami. Rhizome of Atractylodes japonica Koidz., Pericarp of Citrus unshiu Markovich were the most commonly used herb except Root of G. uralensis Fisch.. Although the evaluation index was different for each study, most of the cases showed that hyperemesis gravidarum was improved. Conclusions: Korean medicine treatment is effective for hyperemesis gravidarum. Further large, well-designed studies are needed to establish the foundation of Korean medicine treatment for hyperemesis gravidarum.

Now many sustitution and false articles is used in korea instead of chenpi. To use chenpi correctly, we will make a quilitative certificational plan of chenpi to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1) Source In china source of Chen-pi is pericarp of citrus reticula Blanco(Family;rutaceae)and in korea source of Chen-pi is pericarp of citrus unshiu Markovich(Family;rutaceae). Though source of both countries are not same, it has no problems because of containing family plants and culture variants. 2) Harvesting and processing After the peel attained full growth, wash cleanly in water. And dry in shade or in low temporature at state of eliminating pericarp. 3) Quality (1) Functional standards Exocarp is soft and clear yellow with numerous oil sports. The less white mesocarp is the better. (2) Physicochemical standards We need to suggest new standards about hesperidin to various conditions by processing methods and storing time. The loss on drying is less than 13.5%. Ash content is less than 4.0%. A standard capacity of hesperidin is more than 4.0%. The content of heavy metal is less than 30 ppm. We can not detect reminding agricultural medicines.

In the present study, ten herbal extracts, Citrus unshiu Markovich, root and stem of Berberis koreana, Morus alba, Dendrobium moniliforme, Aster gramineus, A. scabar, Alisma canaliculatum, Fallopia japonica and Origanum (O.) vulgare were determined to examine anti-mycoplasmal activity. Among them, O. vulgare extract (OVE) showed strong anti-mycoplasmal activity and was analyzed by gaschromatography/ mass spectrometry (GC/MS). As the results, OVE was consisted of carvacrol (68.78%), o-cymene (9.80%), terpinene (7.61%) and thymol (4.03%) as main ingredients. To investigate inflammatory activity by intact pathogenic Mycoplasma hyopneumoniae (M. hyo) at 30 $\mu$g/ml, we examined induced transcription of proinflammatory cytokines such as cyclooxygenase-2, tumor necrosis factor-a, interleukin (IL)-1, IL-6 and inducible nitric oxide synthase in RAW 264.7 cells. With the above results, we further investigated whether OVE could reduce inflammation induced by M. hyo at minimal inhibitory concentration. The result showed that 32 $\mu$g/ml of OVE inhibited nitric oxide production by 60%. This study also evaluated the combination of OVE with antibacterials against M. hyo for application. Based on these results, it could be concluded that M. hyo induces inflammation in RAW 264.7 cells and OVE protects this inflammation, indicating that OVE may be useful for industrial animals.

Objective : Citri Unshius Pericarpium is the dried peel of mature fruit of Citrus unshiu Markovich and has been used to treat indigestion, vomiting, and removal of phlegm. This study investigated the hepatoprotective and antioxidant effect of CEE (Ethanol extract of Citri Unshius Pericarpium) in cadmium (CdCl₂)-treated HepG2 cells. Methods : Component analysis of Citri Unshius Pericarpium was analyzed by UPLC with C₁₈ column. Cell viability was determined by MTT assay. The enzyme activity of superoxide dismutase (SOD) and the level of reactive oxygen species (ROS) and reduced glutathione (GSH) were analyzed using commercially available kits. Results : Cadmium caused severe HepG2 cell death. Cadmium also increased ROS production, consistent with depletion of GSH and inhibition of the SOD enzyme. However, CEE treatment reduced cell death and relieved oxidative stress caused by cadmium toxicity. CEE lowered ROS levels and improved depletion of GSH levels. CEE also enhanced the enzymatic activity of SOD. In component analysis, hesperidin was the most abundant of the five marker compounds (Narigenin, Narigin, Narirutin, Hesperidin and Hesperidin), which assumes that hesperidin partially contributed to the antioxidant activity of CEE. Conclusion : These results suggested that CEE could be a potential substance to solve heavy metal-related health problems. In particular, inhibition of oxidative stress by CEE can be a way to treat liver damage caused by cadmium.
