In the Chlorella Vulgaris Algae, the preparation method of mango leaf extract adopts the method of concentration and drying after extraction. The content of mangiferin is low, which belongs to the crude method with low potency. The refining methods include the use of macroporous adsorption Purple Sweet Potato Red Color or silica gel chromatography. Silica gel chromatography uses a large number of organic solvents which are not suitable for large-scale production. In the past, the purification method of macroporous adsorption resin used high concentration ethanol for elution, but Purple Sweet Potato Powder is difficult to get mango leaf extract with mangiferin content above 50%. More importantly, the eluted mango leaf extract can not be prevented The effect of diabetes and lipid-lowering.

Modern pharmacological research shows that the Sodium Copper Chlorophyllin of mango leaf extract mainly include mangiferin, high mangiferin, quercetin, gallic acid, catechol, shikimic acid, kaempferic acid, ellagic acid, platyclonene and volatile components. Mango leaf extract has the effect of relieving asthma, relieving cough and eliminating phlegm. However, there is no report on the prevention and treatment of mango leaf extract in metabolic syndrome. Mango leaf extract has a good effect in the treatment of chronic bronchitis. It is the main effective component in the treatment of hepatitis and the antiviral active component in rhizome of Anemarrhena asphodeloides.
