82 species of Korean medicinal plants were measured to their SOD (superoxide dismutase) activity, total phenol and individual phenol compounds. The SOD activity of medicinal plants was varied from 3.67% to 48.3%, and especially, 4 species including Polygala tenuifolia Willd. showed activity over 40% higher than other species. The 16 individual phenol compounds concentrations have a severe variation in medicinal plants. Codonopsis lanceolata is the highest concentration $(12,176\;{\mu}g/g)$, and 10 species including Glycyrrhiza uralensis Fisch were showed to concentrations more than $1,000\;{\mu}g/g$. And also, salicylic acid was generally found in many plants, but trans-cinnamic acid, naringenin and kampferol was little found in plants. The total phenol by Folin-Dennis methods showed a respectively variation $(3{\sim}249.731\;{\mu}g/g)$ in 82 medicinal plants, and 7 species including Astragalus membranaceus showed low total phenol concentrations less than $10\;{\mu}g/g$. In conclusion, we expect that selecting medicinal plants with high biological activity might develop to chemicals related to antioxidants, as well as these become most popular substance at many industrial materials, and suggest to more researchs in future.

Medicinal plants with synergistic effects on growth inhibition of canter cells under oxidative stress were screened in this study. Methanol extracts from 51 natural medicinal plants which were reported to have anticancer effort on hepatoma stomach cancer or colon cancers which are frequently found in Korean, were prepared and screened for their synergistic activity on growth inhibition of cancer cells under chemically-induced oxidative stress by using MTT assay. Twenty seven samples showed synergistic activity on the growth inhibition in various extent under chemically-induced oxidative stress. Among those samples, eleven samples such as Melia azedarach, Agastache rugosa, Catalpa ovata, Prunus persica, Sinomenium acutum Pulsatilla koreana, Oldenlandia diffusa, Anthriscus sylvestris, Schizandra chinensis, Gieditsia sinensis, Cridium officinale, showed decrease in $IC_{50}$ values more than 50%, other 16 samples showed decrease in $IC_{50}$ values between 50-25%, compared with the value acquired when medicinal plant sample was used alone. Among those 11 samples, extract of Catalpa ovata showed the highest activity. $IC_{50}$ values were decrease to 61% and 28% when carcinoma cells were treated with Catalpa ovata extract in combination of 75 and 100 uM of hydrogen peroxide, respectively.

미얀마 Indo-Burma 지역은 13,500종의 식물종이 분포하고 있는 생물다양성 핫스팟이다. 북부 산악지역에서 남부의 망그로브 지역에 이르는 다양한 특성의 생태계로 구성되어있다. 그러나, 풍부한 생물 다양성은 인간에 의해 인위적인 간섭, 개발, 모노크림 재배와 같은 지속적인 삼림 벌채로 위협 받고 있다. Dprovidedc와 Krupnick (2018년)은 123과 472종의 미얀마 약용식물을 학명, 영명, 미얀마 식물명 그리고 미얀마 현지에서 쓰이고 있는 약용식물의 활용 및 보존 상태를 종합적으로 정리했다. 이 중 약 13%가 보존 상태에 대한 평가를 받았으며 IUCN의 멸종 위기 종 목록(IUCN2017)에 등재되었다. 비록, 전국에 다양한 식물 및 생물 다양성이 분포되어 있지만, 미얀마는 여전히 지속 가능한 관리와 사용을 위한 인적자원과 시설이 부족하다. 국립수목원(KNA)은 2013년부터 미얀마 천연자원환경보전부(MINISTRY OF NATURAL RESOURCES AND ENVIRONMENTAL CONSERVATION, MONREC)와 미얀마 산림과학원(Forest Research Institute, FRI)과 함께 미얀마 보호지역 및 Saggaing 지역 내 식물 다양성 보존을 위한 공동 현장조사, 연구 및 출판 등의 협력사업을 진행하고 있다. 또한 국립수목원(KNA)는 약용으로 가치가 있는 미얀마 식물 생체를 수집, 현지외 보전 중이며 이중 65과 326종의 식물 생체를 국립수목원(KNA)에 있는 열대식물자원연구센터에 보존과 교육 목적으로 전시 중이다. 이 기증은 미얀마에서 식물생체를 국외로 반출한 첫 번째 사례이며 국립수목원(KNA)은 2008년 독일에서 열대식물을 기증받은 사례 다음으로 두 번째로 외국 정부의 공식적인 대량 식물 도입 사례이다. 도입한 식물 중 Santalum album L. 과 Amorphopallus paeoniifolius (Dennst.) Nicolson. 은 IUCN Red List of Threated Spiences (IUCN2017)에 취약(Vulnerable, VU), 관심필요(Least Concern, LC)로 분류되어 있다. 국립수목원 (KNA)는 2019년 6월 17일 개최된 "2019 아태지역 산림주간 및 28차 아태지역 산림위원회"에 참가하여 미얀마 도입식물 전시회를 개최 하였고, 국내 최초로 Amorphopallus paeoniifolius (Dennst.) Nicolson.의 Leaf Cycle을 타임랩스 촬영하여 국립수목원 웹진(10월 호) 과 YouTube에 연구성과를 홍보하고 있다. 또한 국립수목원 열대식물자원연구센터는 2,700여종의 미얀마, 라오스 등 무한한 가치를 지닌 열대식물의 수집 보전으로 기초 응용 연구기반을 구축하여 국민들에게 열대식물의 중요성과 잠재적인 자원가치를 알리는 역할을 하고 있다.

One hundred sixty species among Korean medicinal plants were tested on their antioxidative potentials. Antioxidants are useful materials which could be expected into development as food preservatives, health foods, cosmetics and drugs. Korean peninsula have many potential in antioxidant source which includes various medicinal herbs. It grounded on the fact that Korean medicinal plants have been used as folk therapy for long time and still do in oriental medicine. From the study, effective free radical scavengers compared with ${\alpha}-tocopherol\;of\;13.5{\mu}g/ml\;in\;RC_{50}$ were Geranium sibiricum, Geum japonicum, Geranium nepalense subsp. thunbergii and Paulownia coreana which showed $19.3{\mu}g/ml,\;22.5{\mu}g/ml,\;23.9{\mu}g/ml,\;and\;27.2{\mu}g/ml$, respectively, Acer mono and 38 plants showed strong potential in inhibition rate on linoleic acid oxidation (above 90%). In conclusion, we expect that the selected medicinal plants must be more studied as antioxidant and then developed as many industrial materials.

We investigated the physicochemical properties of Ganjang added to a medicinal herb extract (functional Ganjang). 1be proximate compositions of conventional Ganjang (control) and functional Ganjang (supplemented with 3% or 5% of an hem extract) were not significantly different Analysis of total and free amino acids indicated 17 different amino acids in both types of Ganjang. Glutamic acid was the most common, followed by valine, leucine, isoleucine, lysine, methionine, phenylalanine, and threonine. Sensory tests of conventional and functional Ganjang found no significant differences. An analysis of flavoring components indicated that flavor-active compounds (paeonol, senkyunolide A, and cnidilide) were present in both forms of Ganjang. Our results suggest that the extract could be used to manufacture fermented soybean products.

미용기능식품은 최근 이너뷰티식품으로도 일컬어지며, 일시적이고 인위적인 방법이 아닌 음식 섭취를 통해 건강과 아름다움을 가꿀 수 있는 식품이다. 기존에 이너뷰티식품은 건강기능식품 중 하나로 인식되었으나 천연재료의 미용효과를 강조한 다양한 식품들이 출시되면서 점차 이너뷰티 식품군이 확대되고 있는 추세이다. 국내에서는 자생식물과 약용식물을 함유한 건강즙, 디톡스음료, 착즙 주스 등의 제품이 항산화 및 피부건강과 같은 마케팅 진행으로 인기를 얻고 있다. 그러나 아직 이너뷰티식품 기업 대부분이 안정적인 매출과 인지도를 구축하지 못하고 있는 상황이며, 대체적으로 중견기업 이상의 기업들이 점유하고 있는 상황이므로 인지도가 낮은 브랜드들은 적극적인 수출활동을 진행하지 않고 있다. 한편 전 세계적으로 이너뷰티식품의 카테고리가 다양화되고 타깃 소비층이 증가하고 있으므로, 적절한 제품 및 마케팅 전략 수립을 통해 시장을 확대해가는 전략이 필요한 상황이다. 따라서 본 기고에서는 이러한 이너뷰티제품의 소재 및 연구방향, 시장동향들을 소개하고자 하며, 이를 통해 이너뷰티식품이 향후 발전해 나아갈 방향을 제시하고자 한다.

The objective of this study was carried out in order to evaluate the antioxidative activities of n-hexane fractions from medicinal herbs. Certain parts from 6 species of edible and medicinal herbs were extracted with methanol. Radical scavenging activity of the n-hexane fractions against DPPH and ABTS radicals were observed to be high in Psoralea corylifolia, and Scutellsria barbata; it also significantly increased (p<0.05). For a comparison of the effect of various concentration of fractions, as the concentration of treatment increased, the antioxidative effects on radical scavenging activity also oncreased; yet it was not significant. The antioxidative effect of medicinal plants was dependent on the concentration but was not significant. Therefore, these results indicate that edible wild plants, such as Psoralea corylifolia, and Scutellsria barbata may be useful as potential antioxidant sources for improving the human antioxidant defense system against disease.

The effect of natural foods, utilizing the extracts or juices of teas(Green tea; Camellia sinesis, Du'chung; Eucommia ulmoides Oliver), medicinal plants(Eu sung cho; Houttuynia cordata Thunb, Sam back cho; Saurus Chinensis, Baek hwa sa seal cho; Oldenladia diffusa Roxb.) seaweeds(Laver; Porphyra tenera, Sea mustard; Undaria pinnatifida, Sea staghorn; Condium fragile) and vegetables(Sweet pepper; Capsicum annuum var. angulosum, Kale; Brassia oleracea var.. acephala, Cucumber; Cucumis sativus, Onion; Allium cepa) and fruits(Tomato; Lycopericon esculentum, Maesil; Prunus mume, Plum; Prunus saticina and Grape; Vitis spp.)on the inhibition of N-Nitrosodimethylamine(NDMA) formation was investigated from the various conditions. The inhibition effect was observed in vitro using the reaction fluids of pH 1.2, 4.2 and 6.0. From the teas and medicinal plants, there was a positive response of NDMA formation; however, From the seaweed extracts, there was a negative response of the inhibition effect of NDMA formation, and as the pH of reaction fluids and the amount of materials increase, the inhibition of NDMA formation was strengthened. The inhibition ratios by the level of pH are as follows: under pH 1.2 vegetable juice were 57.6∼99.7% and fruits were 35.9∼99.7%; under pH 4.2 vegetable juice were 55.0∼97.5% and fruits were 21.3∼96.8%. All of the materials observed has been proved and shown the inhibition effect of NDMA formation.
