본 연구에서는 구절초를 대상으로 물과 에탄올을 이용하여 확보한 각각의 추출물에 대하여 추출 수율, 폴리페놀 함량, 플라보노이드 함량, linarin 함량, ABTS 라디칼 소거능과 DPPH 라디칼 소거능, α-glucosidase 저해 활성, lipase 저해 활성을 측정하였다. 구절초는 70°C, 50% 주정 추출조건에서 추출 수율과 총플라보노이드 함량, linarin 함량, ABTS 라디칼 소거능과 DPPH 라디칼 소거능, α-glucosidase 저해 활성, lipase 저해 활성이 가장 높았다. 또한, linarin 함량이 구절초 추출물의 생리활성과 상관관계가 있음을 확인하였다. 구절초 추출물은 linarin 함량이 증가함에 따라 항산화, 탄수화물 및 지방 흡수 지연 활성을 가지는 것으로 생각한다. 본 연구를 통하여 구절초의 추출조건에 따른 생리활성을 확인함으로써 향후 구절초를 이용한 건강기능식품의 소재 등으로 이용 가능할 것으로 생각한다. This study was designed to determine optimal extraction conditions of Chrysanthemum zawadskii (CZ) with high yield of bioactive compounds (linarin, polyphenols, and flavonoids) and improved in vitro activities. Ethanol extracts were examined at different concentrations (0, 30, 50, 70, and 95%) and temperatures (50 and 70°C). The recommended extraction conditions were 50% ethanol at 70°C for 4 h, which gave the highest yield of linarin, polyphenols, and flavonoids. This extract appeared to have the greatest ABTS and DPPH radical scavenging activities (87.81% and 51.42% at 500 μg/mL, respectively) and α-glucosidase (74.59%) and pancreatic lipase inhibitory activities (90.44%). As contents of linarin increased, antioxidative activity, inhibitory effects of carbohydrates and lipid absorption of CZ extracts increased as well. From these results, CZ extracts can be used in functional food industries.
Impacts of Ukraine-Russia Conflict on Global Grain Prices

Global grain prices, which rose after the second half of 2020, expedited the speed amid the protracted war in Ukraine, mainly triggered by price surges in wheat, maize, and barley, which are the Black Sea region’s major exports. • The Chicago Board of Trade (CBOT) futures prices of wheat, maize, and soybeans in March 2022 rose by 137.7%, 102.1%, and 72.0% compared with the average March prices. Concerns about grain export decrease in the Black Sea region due to the war and major grain exporters’ restriction on outbound shipments caused the rise. Ukraine and Russia are one of the largest producers and exporters of maize, wheat, and sunflower oil. • Ukraine’s shares in the international grain trade amount to 14% for maize, 9% for wheat, 10% for barley, and 43% for sunflower oil. Russia takes a 20% share for wheat, 14% for barley, and 20% for sunflower oil. The grains from the Black Sea region are mostly shipped to Europe, the Middle East, Southeast Asia, and China. Russia’s war on Ukraine will likely raise wheat and maize prices by 10-20% in 2022/23. If the conflict continues longer than expected, price hikes will keep up. • The region’s wheat and maize exports will likely decrease by 7 million tons and 6 million tons in 2021/22. Meanwhile, Ukraine’s spring crop output and cultivation areas for summer crops will shrink by 30% each. South Korea highly depends on maize for processing (including non-GMO maize) and feed wheat exported from the Black Sea region. Although the nation can find replacements in other countries, upward pressures on domestic prices will be unavoidable. • Korea relies on imported grains for assorted feed and food manufacturing. As a result, international supply bottlenecks and following price volatilities affect production activities in domestic industries such as feed and food processing, livestock production, and restaurants. • Russia’s invasion of Ukraine drove up consumer prices of processed foods by 3.4-6.8%, dine-out services by 0.6-1.2%, and producer prices of animal feed by 5.3-10.6%. In the short term, the government must develop replacement sources and extend financial and tax aid to minimize impacts on domestic prices. In the long term, it should expand domestic output bases, including grain stockpiling, and help domestic grain distributors enter the international distribution market to set up the nation’s procurement platform. • As grain prices surged amid the conflict in the Black Sea region after their rise in the second half of 2020, the government activated a response system led by the grain policy committee to tackle challenges from international price surges.
