Edible fungi increase production special
1. Drug administration. When formulating the edible mushroom culture medium, proper amount of sulfate (calcium sulfate or magnesium sulfate), phosphate (calcium superphosphate or potassium dihydrogen phosphate) and vitamin B1 are added, and 0.1 to 0.2 mg/liter of trisodium is used during the later stage of mycelial growth. Decadecyl alcohol sprayed on the culture material can promote the growth of mushroom and fruit body, and generally can increase production by about 15%. 2. Drill holes and sand. In the edible fungus bed material surface hole filling sand, that is, when sowing with a diameter of 1.5 cm, a 30 cm long conical wood rod, according to the horizontal and vertical rows are 30 cm specifications were plum shape hole , Deep to the bottom, two days later fill the hole with yellow sand (need to be sterilized with 1% potassium permanganate solution), fill 0.5-1 cm above the material surface, and inject 0.3%-0.5 into the hole at the same time. % lime water. This method can improve the air permeability of the mushroom bed, improve the water retention performance of the material surface, and can produce mushrooms in 3 to 4 days in advance. The mushroom buds are evenly distributed and the fruit is thick and thick, and the yield is increased by about 20%. 3. Stress stimulation. The use of old newspapers, sacks, fine soil, etc. to cover the surface of edible fungi culture materials, and to promote the rapid growth of mycelium through pressure stimulation and heat preservation. This method can generally increase production by about 15%. 4. Plug contact. Use a sterile wooden stick (1 cm in diameter and 3 cm in length) to insert into the edible mushroom culture medium, 2 cm in depth and 15 cm in 15 cm in density. When the mycelium grows and spreads and touches a small wooden stick, it can be wound on it. Form a uniform, dense mycelium, and develop into mushroom buds and fruit bodies. This method can generally increase production by about 20%. 5. Sausage bacteria promote bud. After the mycelium is stuffed with bacteria, use a clean bamboo broom to gently sweep back and forth on the surface of the material to remove or destroy the old and delicate hyphae of the surface. After the new hyphae are exposed, spray water and cover the film to moisturize and keep warm. It takes about 7 days. This method can not only promote mushrooming, but also increase production by about 10%. Disclaimer: Some articles in this website have been transferred from the Internet.

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.
