  • 최근 들어 콩을 채소처럼 먹을 수 있는 풋콩에 대한 관심이 증가하여 그동안 풋콩 전용품종들이 개발 보급되어 왔으나 대부분 조생종인 하대두(올콩)형이었며, 과거 우리 선조들이 이용했던 검정 및 갈색 종피를 가진 유색콩을 재배하여 종실에 착색이 시작되는 성숙시($R_7$ 단계)에 수확, 9 10월 추석 송편속이나 밥밑용으로 이용하는 풋콩품종은 적었다. 따라서 콩의 국내 자급율 향상과 이용도를 다양하게 확대할 목적으로 9 10월경 수확할 수 있는 적합한 품종을 선발하기 위하여 유색콩 품종들의 생육 및 수량을 포함한 풋콩 특성을 비교한 결과를 요약하면 다음과 같다. 1. 유색 장려품종 6개와 재래품종 3개 등 9품종을 공시하여 발아특성을 비교한 결과 출아는 립중이 무거울수록 지연되는 경향을 보였으나 출아율은 유의차가 없었다. 2. 수확기는 검정올콩이 7월 30일로 가장 빨랐으며, 논산재래가 10월 21일로 가장 늦은 극만숙종이었다. 3. 경장은 $25{\sim}104\;cm$로 넓은 범위를 보였으며, 아산재래가 104 cm로 가장 커서 도복지수가 높았으며, 검정올콩이 25 cm로 가장 작았다. 4. 개체당 협수는 $9{\sim}111$개의 분포를 보였는데 가장 많은 품종은 일품검정콩으로 111개이었고 가장 적은 품종은 아산재래로 9개이었다. 5. 풋콩 특성 중 2립협 이상 비율이 높은 품종은 검정올콩이 82%로 가장 높았으며, 황금콩과 검정콩1호가 각각 78%와 73%로 비교적 높았다. 6. 10a당 생협수량은 일품검정콩이 1,567 kg으로 가장 많았으며, 선흑콩 1,468 kg과 갈미콩 1,397 kg으로 많은 수량을 보였다. 따라서 공시된 9품종 중에서 9 10월에 추석 송편속이나 밥밑용으로 이용할 수 있는 것으로 상품성에서는 검정올콩, 황금콩 및 검정콩 1호가 높으나 수량이 너무 낮았고, 수량성이 좋은 일품검정콩, 선흑콩, 갈미콩이 풋콩 재배에 적합한 품종이라고 판단된다.

  • Cancer is a major health obstacle around the world, with hepatocellular carcinoma (HCC) and colorectal cancer (CRC) as major causes of morbidity and mortality. Nowadays, there isgrowing interest in the therapeutic use of natural products for HCC and CRC, owing to the anticancer activity of their bioactive constituents. Boswellia serrata oleo gum resin has long been used in Ayurvedic and traditional Chinese medicine to alleviate a variety of health problems such as inflammatory and arthritic diseases. The current study aimed to identify and explore the in vitro anticancer effect of B. Serrata bioactive constituents on HepG2 and HCT 116 cell lines. Phytochemical analysis of volatile oils of B. Serrata oleo gum resin was carried out using gas chromatography-mass spectrometry (GC/MS). Oleo-gum-resin of B. Serrata was then successively extracted with petroleum ether (extract 1) and methanol (extract 2). Gas-liquid chromatography (GLC) analysis of the lipoidal matter was also performed. In addition, a methanol extract of B. Serrata oleo gum resin was phytochemically studied using column chromatography (CC) and thin layer chromatography (TLC) to obtain four fractions (I, II, III and IV). Sephadex columns were used to isolate ${\beta}$-boswellic acid and identification of the pure compound was done using UV, mass spectra, $^1H$ NMR and $^{13}C$ NMR analysis. Total extracts, fractions and volatile oils of B. Serrata oleo-gum resin were subsequently applied to HCC cells (HepG2 cell line) and CRC cells (HCT 116 cell line) to assess their cytotoxic effects. GLC analysis of the lipoidal matter resulted in identification of tricosane (75.32%) as a major compound with the presence of cholesterol, stigmasterol and ${\beta}$-sitosterol. Twenty two fatty acids were identified of which saturated fatty acids represented 25.6% and unsaturated fatty acids 74.4% of the total saponifiable fraction. GC/MS analysis of three chromatographic fractions (I,II and III) of B. Serrata oleo gum resin revealed the presence of pent-2-ene-1,4-dione, 2-methyl- levulinic acid methyl ester, 3,5- dimethyl- 1-hexane, methyl-1-methylpentadecanoate, 1,1- dimethoxy cyclohexane, 1-methoxy-4-(1-propenyl)benzene and 17a-hydroxy-17a-cyano, preg-4-en-3-one. GC/MS analysis of volatile oils of B. Serrata oleo gum resin revealed the presence of sabinene (19.11%), terpinen-4-ol (14.64%) and terpinyl acetate (13.01%) as major constituents. The anti-cancer effect of two extracts (1 and 2) and four fractions (I, II, III and IV) as well as volatile oils of B. Serrata oleo gum resin on HepG2 and HCT 116 cell lines was investigated using SRB assay. Regarding HepG2 cell line, extracts 1 and 2 elicited the most pronounced cytotoxic activity with $IC_{50}$ values equal 1.58 and $5.82{\mu}g/mL$ at 48 h, respectively which were comparable to doxorubicin with an $IC_{50}$ equal $4.68{\mu}g/mL$ at 48 h. With respect to HCT 116 cells, extracts 1 and 2 exhibited the most obvious cytotoxic effect; with $IC_{50}$ values equal 0.12 and $6.59{\mu}g/mL$ at 48 h, respectively which were comparable to 5-fluorouracil with an $IC_{50}$ equal $3.43{\mu}g/mL$ at 48 h. In conclusion, total extracts, fractions and volatile oils of B. Serrata oleo gum resin proved their usefulness as cytotoxic mediators against HepG2 and HCT 116 cell lines with different potentiality (extracts > fractions > volatile oil). In the two studied cell lines the cytotoxic acivity of each of extract 1 and 2 was comparable to doxorubicin and 5-fluorouracil, respectively. Extensive in vivo research is warranted to explore the precise molecular mechanisms of these bioactive natural products in cytotoxicity against HCC and CRC cells.

  • Primula malacoides $F_1$품종 육성을 위한 순계를 확보하기 위하여 자가 수정 또는 형매교배에 의한 채종에 의한 6세대에서 생장 및 개화특성이 균일하다고 판단되는 10개 계통을 선발하였다. 선발 계통의 초장은 20.8 cm에서 33.2 cm이었고, 엽수는 33.6개에서 54.2개이었다. 선발계통의 개화는 파종 후 181.4일에서 207.8일 사이에 되고, 190일 미만으로 꽃이 일찍 피는 계통은 'PR-03-81'등 3개이고 200일 이후에 피는 계통은 'PR-03-228'등 6개이다. 화색은 분홍색 계통은 'PR-03-81'등 6개, 보라색 계통은 'PR-03-236' 등 3개, 흰색은 'PR-03-275'이다. 화경은 2.4-2.9 cm이고, 소화경의 수는 15.4개에서 26.4개이고, 소화경당 개화수는 대부분 많아서 20.2개에서 30.2개를 나타냈다. 한편 이들 계통의 발아율은 70% 이상으로 양호한 편이고 꼬투리 당 종자수는 110.0개에서 162.8개로 많이 형성되었다. 이와 같이 Primula malacoides의 고정 계통은 초장 및 화경은 작으나 회수 및 엽수가 많고 종자 형성이 잘 되었다. 선발한 고정계통 자체만으로도 관상가치가 있지만 이들을 이용한 일대잡종의 품종이 기대된다.

  • The abolishment of the red ginseng monopoly act by the Korean government in 1996 resulted in a drastic change in the Korean ginseng industry, leading to a significant increase in the market size and consumption of ginseng products. Red ginseng is most popular type, with approximately 74% of harvested fresh ginseng being processed into various red ginseng products. Since 1997, there has been a substantial increase in the cultivation of ginseng for production of red ginseng, which, in turn, has contributed to the proliferation of ginseng processing companies. To investigate the products of ginseng manufacturing businesses, we select 200 companies primarily engaged in ginseng processing or specializing solely in ginseng. Our survey on the status of ginseng industry covered 8 different categories. 1) Root ginseng: There were 66 companies involved in manufacturing red ginseng root, accounting for 33.0% of all surveyed companies. This was followed by black ginseng root with 36 companies (18.0%) and red ginseng fine roots with 22 companies (11%). 2) Red ginseng products: A total of 144 companies were involved in manufacturing red ginseng pouches, making it the most common product category. This was closely followed by 142 companies producing pure(100%) red ginseng extract concentrate. 3) Fermented red ginseng products: Companies producing fermented red ginseng extract concentrate products were the most numerous, totaling 26. Following this, companies producing fermented red ginseng stick and pouch products were next in line. 4) Ginseng products: There were 15 companies involved in the production of ginseng products, with the majority focusing on ginseng tea. 5) Black ginseng products: Companies producing black ginseng extract concentrate were the most numerous, with 31 companies, followed by 26 companies producing black ginseng extract pouches. 6) Taegeuk ginseng products: Only 5 companies were involved in the production of taegeuk ginseng products. 7) Fermented black ginseng, and 8) Ginseng berry products: These categories are manufactured by less than 5 companies each. However, the variety in ginseng berry products suggests the potential for future growth. In the 2000s, a trend emerged with the development of new processed products aimed at enhancing the functional components of red ginseng, and these products have captured the attention of consumers. However, this study primarily focuses on black ginseng, fermented red ginseng/fermented black ginseng, and ginseng berry products as they have exerted a significant influence on the overall ginseng industry.
