At the 13th China Food Safety Conference held recently, Teng Jicai, Deputy Director of the State Food and Drug Administration revealed that the State Food and Drug Administration is working with relevant departments to draft regulations for the implementation of the Food Safety Law and formulate relevant supporting regulations. We will establish and improve a food safety law and regulations system that is compatible with the new law as soon as possible. Teng Jiacai said that although the food safety rule of law has made major achievements, the supervision and law enforcement efforts have been continuously strengthened, and the food safety protection system is gradually improving, but the food safety situation is still not optimistic. He also pointed out that the foundation of China's food safety is still relatively weak, and Internet marketing has brought new challenges to food safety supervision. With the weak ability of grassroots regulatory technologies, food safety issues are still more prone to occur. Jin Xiaotao, deputy director of the National Health and Family Planning Commission, said that the Health and Development Commission has also further improved the food safety standards system and led the clean-up of nearly 5,000 food standards, which contain more than 10,000 indicators. At present, the Health and Family Planning Commission has formulated and announced 636 new national food safety standards and will exceed 1,000 by the end of the year. (Hu Xiaohong Wen Lele)

Plant extraction process
1. Select plants/herbs. No more than ancient prescriptions, prescriptions, folk herbs to find. At present, common and uncommon herbs have been studied. At present, it is mostly to increase the amount of medicinal materials to extract and separate components with low content, or to find medicinal plants that have never been studied from miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.

2. The extraction. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (low polarity → high polarity). Daily medicine decoction effective, water and ethanol and other solvents with large polarity, such as artemisinin boiling ineffective extraction with petroleum ether and other solvents with small polarity. Common medicinal materials water/alcohol/ether to go through, separation and identification of more compounds.
3. The separation. This is the most important work. In the solution extracted from the second step, there are dozens of compounds, usually by column chromatography, which is often referred to as the column flushing. It's a lot of work, it's boring, it's low tech. A master's student might do this every day for two years. The column for separating compounds, as shown below, is as large as 2 meters high and as small as 10 centimeters. Change the solvent condition of mobile phase, change the material of column, different conditions and different separation principles of column repeatedly punching, can be separated from the monomer compound.
