1406-65-1 Natural Herbal Extracts Chlorophyll Extract For Dyeing Of Essential Oil

 Product Info :

Chlorophyll a: Magnesium complex salt of1,3,5,8-tetramethyl-4-ethyl-2-vinyl-9-oxo-10carbome-thoxyphorbin-7-propionic acid phytyl ester, R = CH3, as a waxy blue-black fine crystalline . Often has a sword or blade-like shape. Soluble in ether, alcohol, acetone, chloroform, benzene and carbon disulfide, insoluble in cold methanol, almost insoluble in petroleum ether. Its alcohol solution was deep red and blue and green fluorescence. Melting point 117-120 ℃ .

Chlorophyll for soap, mineral oil, wax and oil coloring. Chlorophyll or chlorophyllin derivatives such as copper chlorophyll [11006-34-1], iron chlorophyllin sodium copper chlorophyllin sodium, used in food, candy, drinks, toothpaste, and other coloring agents, and sweetening agents. Chlorophyllin derivatives with fungicides benzalkonium chloride, halogen card classes and used as foul cosmetics formulations.

Most plants (such as spinach, etc.) or dried silkworm sand as raw material to extract chlorophyll. For example, the following method may be used to extract chlorophyll from silkworm sand. Organic solvent extraction: Take a clean silkworm sand, with more than 70% of industrial ethanol slurried, dark green solution was filtered off, then dried derived. Another operation is 45 parts of petroleum ether and 15 parts of methanol, 4 parts of benzene were mixed in mashing and clean silkworm sand, filtered and the filtrate was washed with water four times. Plus a small amount of sodium in the organic extract to remove residual water, filtered, and the filtrate solvent recovery after the chlorophyll. Physical Separation: 0.4mol / L dilute sugar solution and 0.06mol / L potassium phosphate dilute solution (pH 6-7) by 1: 1 mix into buffered media. Silkworm sand around 2kg per 1L buffer medium, mixed with emery cloth multilayer green suspension was filtered off, placed in low temperature centrifuge 5-10min, washed with water, precipitation, centrifugal chlorophyll precipitate. Chlorophyll treated with oxalic acid, can be obtained without pheophytin magnesium, magnesium reintroduced back into chlorophyll. Plant with a strong acid to remove the alcohol and magnesium Detuo magnesium chlorophyllin, plant alcohol can also be re-introduced. Hydrolysis to remove the alcohol plant of methanol, chlorophyllin.
