Insampaedoksan (IS) is the decoction of medicinal herbs, which was commonly used for anti-inflammatory and anti-pyretic in the Korean traditional medicine (KTM). Several studies on improving efficiency or searching new efficiency by fermenting traditional herbal medicines are recently in progress. The bioconversion has been conducted on IS using various bacteria. Liquiritin, ferulic acid, hesperidin, liquiritigenin, and glycyrrhizin in IS before and after fermented IS were simultaneously analyzed. These compounds were qualitatively analyzed and quantitatively analyzed using the HPLC-DAD system. The identifications of liquiritin, ferulic acid, hesperidin, liquiritigenin and glycyrrhizin were achieved by comparing the HPLC retention time ($R_t$) and the UV absorption of five pure compounds in the IS. As a result, the increased constituents were identified to be liquiritin, liquiritigenin and glycyrrhizin, while the decreased constituent was ferulic acid and the constituent of hesperidin was similar to before and after fermentation. Insampeadock-san fermented by Lactobacillus plantarum KFRI 144 exhibited the most remarkable changes in all of fermentation.

The fermentation of medicinal herbs facilitated by microbes is assumed to exert promising therapeutic efficacy on the absorption, bioavailability, and pharmacological effects by speeding up the making or conversion of active constituents into their metabolites. We examined the cardioprotective potential of fermented ginseng, GBCK25, against high-fat diet (HFD)-induced metabolic and functional illnesses as following the essential analysis such as electrocardiographic parameters, alterations of body and organ weights, and echocardiographic studies. The results exhibited that body weights were significantly reduced and the gain of different organ weights were partly eased by GBCK25 treatment. Echocardiography results proposed the amelioration of heart function through normalized levels of left ventricle systolic pressure, ejection fraction, and fractional shortening. These outcomes deliver straight confirmation that GBCK25 could be a potential nutraceutical source for the relief of HFD-induced obesity mediated cardiac dysfunctions.

본 연구는 발효 옻나무와 구절초를 복합소재로 활용하여 화장품 소재로서의 개발 가능성을 확인하고자 항산화, 항주름 및 미백활성을 검증하였다. 구절초와 발효옻나무를 각각 및 각 비율별로 혼합하여 항산화 활성, 항주름 활성, 미백활성을 확인하였다. 구절초와 발효옻나무의 최적 혼합비율을 설정하기 위해 다양한 혼합비에서 선별하였으며, 구절초 1: 옻나무 9의 활성이 가장 효과적이었다. 혼합물의 DPPH, ABTS 라디칼 소거활성은 $1,000{\mu}g/ml$에서 각각 $95.78{\pm}3.24%$, $99.01{\pm}1.80%$로 나타났고, reducing power은 $1,000{\mu}g/ml$에서 $81.48{\pm}1.47%$로 확인되었다. Tyrosinase 저해활성은 $1,000{\mu}g/ml$에서 $16.74{\pm}1.85%$로, Collagenase 저해활성은 $20{\mu}g/ml$에서 $112.40{\pm}7.75%$로 나타났다. 미백 활성을 확인하기 위한 대조군으로 arbutin을 사용하였으며, B16 F10 세포를 통한 미백 활성은 혼합물 처리에 의해 tyrosinase, TRP-1, TRP-2, MITF protein 및 mRNA 발현을 유의성 있게 저해하였으며, arbutin과 유사한 효과를 나타냈다. 또한 wound healing assay를 통한 피부 장벽 손실 억제 효과를 확인하였다. 따라서 본 연구에서는 구절초와 발효옻나무의 혼합물의 높은 항산화, 항주름 및 미백활성을 통해 천연화장품의 소재로서의 높은 가치를 확인하였다.

홍국은 한국에서 오랫동안 음식과 전통의학 소재로 사용되어 왔다. Monascus sp.의 생장과 2차 대사과정을 통해 Monascus 색소, monacolins, γ-aminobutyric acid 등을 생산할 수 있다. Monascus 종의 대사산물인 monacolin K, γ-aminobutyric acid과 dimerumic acid는 특정 항산화 효과로 인해 콜레스테롤과 혈압을 낮춘다고 알려져 있다. 이 연구는 Monascus sp.로 발효된 홍국쌀 에탄올 추출물의 항염증 활성을 조사하였다. 홍국 에탄올 추출물의 총 폴리페놀 함량을 측정하였고, 항염증 효과는 LPS가 유도된 Raw 264.7 cell에서 NO 생성, iNOS 및 사이클로옥시게나아제-2(cyclooxygenase-2 (COX-2)) 단백질 활성을 측정하였다. 총 폴리페놀 함량은 발효되지 않은 일반쌀보다 높은 함량을 나타내었다. NO 생성 저해활성 평가는 400 ㎍/ml 농도에서 LPS를 처리하지 않은 음성대조군의 NO 생성량과 유사한 결과를 나타내었다. iNOS 및 COX-2 단백질 발현 저해활성은 400 및 800 ㎍/ml에서 iNOS의 발현을 상당부분 억제하였다. 홍국 에탄올 추출물은 높은 항염증 효과를 확인하였으며, 기능성화장품 및 항염증소재로서 활용 가능할 것으로 사료된다.

Mume fructus is the roasted fruits of Prunus mume and has been used as traditional chinese medicine. In this study, mume fructus extracts were prepared by three different methods including hot water extract (sample1), fermentation extract using Lactobacillus (Sample2-LP and sample-LA) and ethanol extract (sample3). Total polyphenol and flavonoid contents were improved by fermentation process, compared to water extract. Sample 3 showed the highest activity in DPPH radical scavenging. The cytotoxicity of the sample 2-LP was in the range of 83.3% cell viability at $300{\mu}g/m{\ell}$ concentration. Mume fructus extracts in a concentration-dependent manner inhibited melanogenesis and NO synthesis was inhibited. Specifically, the extracts fermented by L. plantarum (sample2-LP) showed higher anti-oxidant activity, anti-inflammatory and skin whitening activity than other extracts. It suggests that sample 2-LP could be potentially used as a resource of materials for functional cosmetics.

강황 (Curcuma longa L.)은 건강기능성 식품의 훌륭한 소재로 전통적인 약용식물이다. 강황의 주요성분인 안토시아닌계인 curcumin은 항균작용, 항암작용, 항산화작용 등 다양한 효능이 있는 것으로 알려져있다. 본 연구는 혼합유산균을 스타터로 사용하여 강황 분말을 첨가한 발효유를 제조하여 발효유의 이화학적 특성 및 항염증 활성을 연구하였다. 발효유의 발효특성은 대조군에 비해 강황 첨가군에서 유산균의 성장이 현저히 빠르게 나타나 pH는 감소되었고 산도는 증가하였다. 또한 우유단백질의 분해도 부분적으로 일어났고 유기산은 lactic acid와 acetic acid가 높게 생성되었다. 기호도는 강황 특유의 쓴맛과 강한 향으로 인해 대조군에 비해 낮았다. 강황 발효유 배양액을 처리한 RAW 264.7 세포주에서 세포독성의 영향은 나타나지 않았다. 염증성 싸이토카인으로 TNF-${\alpha}$와 IL-6는 강황 처리군이 대조군에 비해 현저히 강하게 발현되었다. 또한 NO의 생성은 강황 처리군이 대조군에 비해 현저히 높았다. 이러한 연구결과는 강황 첨가가 유산균의 성장을 촉진시켜 발효유 제조에 도움을 주고, 염증활성을 조절하므로 강황을 이용한 발효유, 음료 제품 및 다양한 기능성 식품 소재로 활용할 수 있는 가능성을 시사하고 있다.

To investigate the effects of medicinal plants on the shelf life of kakdugi, various kakdugies, added with hot water extract from 62 natural plants, were fermented at 20oC for 15 days. In case of control without the addition, the shelf life required to reach the acidity of 1%(as lactic acid) was 7 days. Morethan two fold extension of shelf life was observed with twenty seven extracts, of which six extracts maintained the hardness of kakdugi higher than that of control over the entire fermentation time. And the number of lactic acid bacteria in above kakdugies was not remarkably different from that of control, and the color(a value) of the liquid of kakdugi, added with Chaenomeles lagenaria, Moringa oleifera, Peaonia lactiflora or Citrus tangerina extract, was similar to that of control. In sensory test, the extracts from the above plants except Moringa oleifera were found to be acceptable. It is suggested that the addition of above three extracts may lead to extension of shelf life of kakdugi, based on the acidity, hardness, color and sensory test.

Since the main symptoms of COVID-19 involve the respiratory system, the infection rate of this disease is predicted to be higher in patients with other respiratory conditions such as allergic rhinitis. In such a situation, it will be meaningful to conduct research on an allergy treatment that has fewer side effects and can effectively reduce allergy symptoms. Here, we prepared experimental samples under various fermentation conditions with mixed extracts of six medicinal plants. To examine the anti-allergic efficacy of these samples, an egg albumin-induced allergic rhinitis animal model experiment, a serum histamine and IgE experiment, and a COX and LO inhibitory activity experiment were conducted. As a result of animal experiments, OVA+SP-4 showed superior efficacy compared to OVA+SP-1 in nasal rubbing and sneezing experiments and had anti-allergic efficacy similar to that of OVA-cetirizine. The serum histamine concentration of OVA+SP-4 was also 1.3 times higher than that of the OVA+cetirizine group, showing a high histamine reduction ability, and IgE showed the same trend. An analysis of COX inhibitory efficacy also confirmed that COX-1 and COX-2 inhibitory efficacy is high, and the longer the fermentation time, the higher the antiallergic efficacy. The composition proposed by this study is expected to have a significant effect on sustainable allergy prevention and treatment in the future by applying it to human patients.
