This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.

본 실험은 일당귀의 개화 후 일수에 따른 종자 등숙 특성을 알아보고자 수행하였다. 2019년 농촌진흥청 약용작물과 시험 포장에서 채종한 종자를 시험재료로 사용하였다. 개화 후 일수에 따라 종자 무게와 발아율이 조사되었고, 등숙 과정 동안 종자 내에서 배종비(E:S ratio)가 측정되었다. 결과적으로는 각 소화서마다 개화 후 일수가 증가할수록 종자 무게가 유의적으로 증가하였으며, 각 소화서에서 발아가 시작되는 시기는 차이가 있었다. 또한 종자 내에서 배의 길이는 계속해서 성장하여 배종비가 높아지는 것을 관찰하였다. 일당귀는 다양한 소화서에서 꽃이 피기 때문에 종자의 배종비가 종자 발아에 영향을 미칠 수 있다. 본 연구를 바탕으로 일당귀의 우량 종자 생산을 위해서는 개화 후 50일부터 70일경이 가장 적합한 것으로 사료된다.

Background : Angelica acutiloba is a perennial herb from the family Umbelliferous. The root was used as a substitute for the crude drug. As a by-product of making cheese from whey, it has many proteins and nutritional components, but it has a drawback in that it must be stored in a refrigerator because the storage facility is short. In order to solve such problems, an attempt is made to solve the environmental and economic problems by producing a liquid fertilizer fermented with a large amount of whey. Methods and Results : In this study, we studied the fermentation of wheat germ with lactic acid bacteria (Lactobacillus brevis) and yeast (Saccharomyces cerevisiae). The preliminary experiment was conducted to determine the test concentration of 300 fold dilution and 500 fold dilution. As a result, the application of 300 times dilution liquid prepared by fermentation of whey using lactic acid bacteria showed higher growth and higher growth rate with higher number of leaves and branches. Growth response of the 500 fold dilution was higher than that of the control, but the growth of 300 fold dilution showed the highest. Conclusion : Therefore, it is considered that the 300 fold dilution of Lactobacillus can be used as a substitute for compost when cultivating medicinal plants.

Background : Angelica gigas is a monocarpic perennial plant. A. gigas, also called DangGui or Korean Angelica, is a major medicinal herb used in Asian countries such as Korea, Japan and China. In Korea, we are using the roots of A. gigas. but, Chinese using Angelica sinensis and Japanese using Angelica acutiloba with the same name 'DangGui'. The biggest problem in the use of A. gigas is the confusion with A. acutiloba or A. sinensis. This confusion can cause an medical accident or lack of pharmacological ingredients. In this study, we developed chloroplast InDel markers that can distinguish A. gigas, A. acutiloba or A. sinensis. Methods and Results : We collected 14 Angelica plant samples including A. gigas, A. acutiloba and A. sinensis and extrated DNA using CTAB method. The DNA was diluted to 10 ng/㎕ and kept -20℃. We designed the primer sets using CLC Main Workbench based on chloroplast DNA InDel region of between A. gigas and A. acutiloba. PCR were performed on the 14 Angelica plant samples including A. gigas, A. acutiloba and A. sinensis (5 repeats each). Electrophoresis was performed using fragment analyzer automated CE system. We designed 6 InDel primer sets and the primer sets amplified the amplicons effectively. Three of the 6 primer sets showed polymorphism. Conclusion : We could distinguish A. gigas, A. acutiloba, and A. sinensis using 2 newly developed InDel markers.

당귀는 타식성 작물로 품종개발과 기본식물의 유지에 많은 노력이 든다. 이러한 요인은 당귀 육종작업을 어렵게 만들고 있다. 따라서 본 연구에서는 참당귀와 일당귀에서 육종작업의 효율성 증진을 위해 화분매개가 가능한 곤충들의 효과에 대해 검토하였다. 당귀에 비래하는 곤충의 대부분은 벌과 파리였으며 그 외의 곤충들로는 나비, 딱정벌레 및 노린재가 있었다. 당귀에 비래하는 곤충의 수는 참당귀에서 월등히 많은 것으로 조사되었다. 화분매개 곤충으로 사용하기 위한 파리의 사육은 소의 허파를 이용하여 비교적 간단하게 할 수 있었다. 참당귀에서 당귀 종자의 결실율은 자연방임구 76.6%, 벌방사구 49.2%, 파리방사구 15.3%, 인공수분구 15.3%로 나타났다. 일당귀에서는 각각 46.9%, 43.6%, 27.9%, 20.3%의 결실율을 나타내었다. 이상의 결과를 종합해 볼 때 자연 방임구를 제외하고는 벌 방사구의 결실율이 가장 높은 것으로 나타났으나, 취급의 간편함과 적은 비용을 감안하면 파리를 이용하는 것이 가장 효율적인 방법으로 판단되었다. 본 연구에서는 파리의 인공적인 사육과 화분매개 효과에 대한 가능성을 확인할 수 있었으며, 이러한 결과들은 앞으로의 당귀 육종작업에 있어서 효율성 증진에 기여할 수 있을 것으로 기대된다.
