The flowers of Magnolia obovata were extracted with aqueous MeOH and fractionated into EtOAc, n-BuOH, and $H_2O$ fractination. Three alkyl glycosides were isolated from the EtOAc fraction through repeated silica gel and ODS column chromatography. The structures were identified to be 2-methylbutan-1-ol-${\beta}$-$\small{D}$-galacto-pyranoside (1), 2-methylbutan-1-ol-${\beta}$-$\small{D}$-glucopyranoside (2), and 2-methylpropan-1-ol-${\beta}$-$\small{D}$-glucopyranoside (3) on the basis of spectroscopic analyses such as fast atom bombardment mass spectrometry, infrared spectroscopy, 1D nuclear magnetic resonance (NMR) ($^1H$ and $^{13}C-NMR$), and 2D NMR (gCOSY, gHSQC, and gHMBC). These compounds were isolated for the first time from the flower of M. obovata in this study.

특허제도는 발명자에게 발명의 공개에 대한 대가로 일정기간 독점권을 인정하여 기술개발에 투자한 자금을 회수할 수 있는 기회를 제공하고 이렇게 공개된 발명은 새로운 기술개발을 위하여 누구나 이용할 수 있도록 하여 기술발전을 촉진할 뿐만아니라 이미 개발된 발명에 대한 중복투자나 중복연구를 하는 낭비를 방지하기 위한 목적을 가진다. 본 조사는 2018년 9월 26일에 정부의 특허정보넷인 키프리스(www.kipris.or.kr)에서 꽃차 관련 상표등록 특허 내용을 검색하여 정리하였으며 결과는 다음과 같았다. 1. 1983년 엘다베리꽃차 제조방법에 대한 것을 시작으로 최근 2018년 까지 총 20개가 출원되었다. 2. 출원된 실용신안 특허 총 20개 중에서 소멸 2개(엘다베리/1983, 연꽃/2009), 취하 2개(무궁화/1992, 백화차/2005), 거절 5개(매화/2001, 장미녹차/2007, 혼합꽃녹차/2007, 동결꽃차/2008, 꽃차/2015), 공개 4개(꽃차/2014, 소금꽃차/2015, 장미꽃차/2017, 동백꽃차/2017), 등록 7개(녹차꽃차/2006, 사과꽃차/2008, 목련꽃차/2012. 목련꽃차/2014, 칡꽃차/2015, 사군자꽃차/2017, 꽃차/2018)였다. 3. 출원된 실용신안 특허 총 20개 중에서 개인이 출원한 것이 16개, 회사(아모레퍼시픽, (주)꽃다비)나 기관(한국식품연구원, 전남대학교산학협력단)이 출원한 것이 4개였다.

본 연구는 조경수목의 목질 내부의 상태 진단과 변색 및 부후 부위의 탐색을 통하여 병든 부위를 조기에 제거. 병의 확산 방지 및 효율적인 예방관리를 위해 Shigometer의 이용가능성을 제시하고자 하였다. 본 연구대상지는 충남 천안시 성환흡 수향리에 위치한 연암축산원예대학으로 하였으며, 대학 구내에 식재된 조경수를 대상수종으로 하였다. 대상수종은 침엽수 7종과 활엽수 16종으로 총 23종을 선정하였다. 조사한 조경수목의 내부 전기저항치는 수종별로 매우 다양하게 나타났다. 평균 내부 전기저항치가 500k$\Omega$이상인 수종은 은행나무, 섬잣나무, 소나무, 단풍나무, 중국단풍. 홍단풍이었으며, 개체간 차이와 측정 깊이에 따른 차이도 심하지 않았다. 그러나 메타세쿼이아, 수양버들, 자귀나무, 회화나무는 200k$\Omega$이하의 낮은 내부 전기저항치를 나타냈다. 측정 깊이에 따른 변화가 심한 수종은 전나무, 메타세쿼이아, 수양버들, 느티나무, 튤립나무, 목련, 일본목련, 핀오크, 벚나무등으로 이들은 측정 깊이에 따라 전기저항치가 갑자기 하락하는 부위를 포함하고 있었으며, 전기저항치가 갑자기 하락하는 부위의 목재는 부후되어 있었다. 결론적으로 Shigometer는 가시적인 피해증상이 나타나기 전 초기단계에서 목재의 변색 및 부후 부위를 찾아내는데 유용하게 이용될 수 있을 것으로 판단된다.

Objective : For the purpose of developing Magnoliaceae plants recorded in Korean Herbology in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : Books and research papers about Herbology which published at Korea and other countries were examined. Results : A list was made about Magnoliaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Magnoliaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Magnoliaceae's properties flavor, channels they use, effects, and toxicity were also noted. Magnoliaceae(grew in Korea) were divided into 5 classes with 16 species. Out of those, 3 classes with 5 species were found serviceable which indicates 32% of all. Out of all 16 species of Magnoliaceae family, Magnolia genus were found 7 species, which were shown the most. Among 3 genus of Magnolia species, medicinal plants were all one species each. Out of all serviceable parts in Magnoliaceae, Flos parts took first place as 3 species. There are no toxic, the survey said. Conclusion : There were totaled to 5 genera and 16 species in Magnoliaceae in Korea and among them medicinal plants are 3 genera, 5 species, some 32% in total.

This study aims to sort out the plants in "Poetry of the South" what is in the written by Qu Yuan in the Kingdom of Chu and to analyze the utility and appreciation of plants. The conclusions are as follows. First, there were 80 plant names and 56 plant species were sorted out, and these results can confirm that the plants were existed in the 340-277 BC. Second, through analyzing the utility of the plants, herba lycopi, basil etc. as the garden plants; lotus, chrysanthemum etc. as the ornamental plants; galangal and cannabis sativa as the present; basil, musa basjoo, etc. as the sacrifice plants. Third, through analyzing the appreciation of the plants, golden birch, chrysanthemum etc. for gustatory appreciation; herba lycopi and pine tree etc. for tactile appreciation; bamboo for sensory appreciation. Forth, through analyzing the token of the plants, calamus and basil etc. are the symbol of personal character noble; wormwood and caltrop etc. are the symbol of villain. Based on the research of "Poetry of the South", it can help to understand the plants culture in 340-277 BC, and it will be a useful information for the plant design.

The antioxidant, antiproliferation, and nitrate synthesis inhibitory effects of Magnolia denudata extracts (ME) were evaluated. The ME was extracted with 70% (v/v) ethanol and fractionated with solvents of hexane, chloroform, ethyl acetate, n-buthanol and aqueous. The ethyl acetate fraction contained the highest phenolic and flavonoid contents of 427.10 mg garlic acid eq/g and 356.05 mg catechin eq/g, respectively. The ethyl acetate fraction showed strong 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity with a 50% inhibition concentration ($IC_{50}$) of 0.20 mg/mL and total antioxidant activity was 0.90 mg AA eq/100 mg. From the results of cytotoxic effects of HCT116, NCL-H460, and HepG2 human cancer cells by MTT assay on the ME and its solvent fraction, chloroform fraction showed the highest cytotoxic effect ($IC_{50}$ value: 0.14, 0.37, and 0.41 mg/mL, respectively). Nitrate synthesis inhibitory effect of ME and its solvent fractions on nitric oxide synthase activity in LPS stimulated RAW 264.7 cells were decreased in dose-dependent manners, and $IC_{50}$ value of hexane and chloroform fractions were 0.39 and 0.49 mg/mL, respectively.
