Chlorophyll b

Chlorophyll b is Light, silvery, metallic element.

Chlorophyll is mostly extracted from plants (such as spinach, etc.) or dried silkworm sand. For example, the following method can be used to extract chlorophyll from silkworm sand. Organic solvent extraction: take clean silkworm sand, adjust it into a slurry with more than 70% industrial ethanol, filter out the dark green solution, and dry it. Another operation is to mix 45 parts of petroleum ether, 15 parts of methanol, and 4 parts of benzene, mix with clean silkworm sand to adjust the slurry, filter, and wash the filtrate 4 times with water. Add a small amount of sodium sulfate to the organic extract to remove residual water, filter, and recover the solvent from the filtrate to obtain chlorophyll. Physical separation: 0.4mol/L dilute sucrose solution and 0.06mol/L dilute potassium phosphate solution (pH 6-7) are mixed 1:1 into a buffer medium. Add about 1L of buffer medium per 2kg of silkworm sand, mix evenly, filter out the green suspension with a multi-layer sand cloth, centrifuge in a low-temperature centrifuge for 5-10min, wash the precipitate with water, and centrifuge again to obtain a chlorophyll precipitate. Chlorophyll is treated with oxalic acid to obtain magnesium-free pheophytin, which is then converted back to chlorophyll by introducing magnesium. Removal of phytol and magnesium with strong acid leads to phytophylloate, and phytol can also be reintroduced. Hydrolysis removes phytol and methanol to obtain chlorophyllic acid. Chlorophyll is mostly extracted from plants (such as spinach, etc.) or dried silkworm sand. For example, the following method can be used to extract chlorophyll from silkworm sand. Organic solvent extraction: take clean silkworm sand, adjust it into a slurry with more than 70% industrial ethanol, filter out the dark green solution, and dry it. Another operation is to mix 45 parts of petroleum ether, 15 parts of methanol, and 4 parts of benzene, mix with clean silkworm sand to adjust the slurry, filter, and wash the filtrate 4 times with water. Add a small amount of sodium sulfate to the organic extract to remove residual water, filter, and recover the solvent from the filtrate to obtain chlorophyll. Physical separation: 0.4mol/L dilute sucrose solution and 0.06mol/L dilute potassium phosphate solution (pH 6-7) are mixed 1:1 into a buffer medium. Add about 1L of buffer medium per 2kg of silkworm sand, mix evenly, filter out the green suspension with a multi-layer sand cloth, centrifuge in a low-temperature centrifuge for 5-10min, wash the precipitate with water, and centrifuge again to obtain a chlorophyll precipitate. Chlorophyll is treated with oxalic acid to obtain magnesium-free pheophytin, which is then converted back to chlorophyll by introducing magnesium. Removal of phytol and magnesium with strong acid leads to phytophylloate, and phytol can also be reintroduced. Hydrolysis removes phytol and methanol to obtain chlorophyllic acid.
