In 2003, Circular No. 32 of the General Administration of Quality Supervision, Inspection and Quarantine was repealed. “Helan Dongluo Wine†is a wine produced in Shandong Helan Autonomous Region Helandongluo Area using self-produced high-quality grapes. With its unique natural resources and a long tradition of winemaking, modernized management methods and brewing technology, Helan Shandong Luan produced The wine was highly praised and attracted domestic and foreign famous wine producers to invest in factories or bases. The area has become one of the best wine and wine producing regions in China, both home and abroad. In 2000, Hu Jintao visited the Yinguangxia grape base and fermentation plant. He tasted "Helanshan" wine and thought that "the quality of the wine is good, the flavor of the wine is very close to that of Europe, and there is no problem in entering the European market". At the end of 2011, the Sino-French wine blind tasting competition organized by France’s “Wine Collection†magazine was held in Beijing. Ten wine tasters from China and France, from France’s Bordeaux-Médoc and China’s Ningxia Helan Mountain Deer Area Dozens of red wines were tasted, of which the top four were taken from the Helan East Foot of Ningxia. The eastern foothills of Helan are located between 105°45′39′′-106°27′35′′ east longitude and 37°43′00′′-39°05′3′′ north latitude, and are located in the “golden zone†of grape growing in the world. Located in the area with arid climate, it is a typical continental climate. It is a three-step alluvial fan. The agglomerate rock is dominated by alluvial deposits. The relief is small, flat, gully is small and shallow, and the soil erosion is light. The soil is light calcareous. The soil is sandy loam, and some soils contain Gravel, soil depth 40-100cm, pH <8.5. The color change period of grapes in the region is from early August to August, and there is a large difference between day and night (10-15°C). The sugar content of grapes can be fully accumulated. At the same time, the phenolic content of grapes is also relatively high. Ningxia Helan Mountain is rich in light energy resources, long sunshine hours, large day and night, sunshine hours in the year 2851 ~ 3106h, annual average ≥ 10 °C, effective product 1534.9 °C, 7-September effective product 961.6 °C. The annual precipitation is 193.4mm. During the period from August to September when the grape berry matured, the rainfall was less. The rainfall of the month before grape harvest was negatively correlated with the quality of the wine, but the area had convenient irrigation conditions.
Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
