Source and composition
Soya Lecithin is yellow to brown semi-solid or lumps of phospholipids extracted and refined from soybeans. They are esters composed of glycerol, fatty acids, choline or cholamine, and are known as the “third nutrients” alongside proteins and vitamins. The composition of soybean Lecithin is complex, calculated as anhydrous matter, containing phosphorus (P) no less than 2.7%, nitrogen (N) should be 1.5-2.0%, containing phosphatidylcholine(PC) 45-80%, containing phosphatidyl ethanolamine(PE) 3-20%, containing phosphatidylcholine(PC) and phosphatidylethanolamine(PE) no less than 70%.
Physical and chemical Properties
Pure Soya Lecithin is a white solid substance that turns yellowish or brown due to reasons such as refining and air contact. Soya Lecithin are soluble in fats, fatty acids, benzene, ether and other organic solvents, partially soluble in ethanol, extremely insoluble in acetone and methyl acetate, insoluble in water. Phospholipids have the properties of hydrophilic colloid, which can absorb water and expand until a colloidal solution is formed. It’s unstable in air or sunlight, prone to oxidation and rancidity and blackening (decomposition). It is easy to hydrolyze into fatty acids, glycerol, phosphoric acid, amino alcohol and inositol (hydrolysis) under acid-base conditions, and its products are . Phospholipids can also be broken down by enzymes (enzymolysis)
physiological function
Phospholipids are a class of lipids containing phosphorus, which have special physiological functions such as promoting cell growth, promoting fat metabolism, regulating blood lipids, improving brain and brain, immune regulation and anti-tumor. They are important components of human and many animal and plant tissues, and play important functions in life activities.
Medicinal Uses
1.Use as an active ingredient
High purity soybean phospholipid can be used for the treatment and prevention of vascular diseases such as liver disease and hyperlipidemia, and related products include soybean phospholipid tablets and soybean phospholipid powder. Common soybean phospholipids are more used in health food with regulating blood lipids, regulating immunity, improving memory and delaying aging.
By-Health Soy Lecithin Soft Capsules
Ingredients: Soy Lecithin
Excipients: Gelatin, Purified Water, Glycerin
2.Used as pharmaceutical excipients
Because phospholipids have amphoteric molecular structure, the polar end containing phosphoric acid and cholinyl group has hydrophilicity, and the non-polar end of the two long hydrocarbon chains has lipophilicity, this unique physical and chemical properties and physiological activity can be used as emulsifiers and excipients for preparing various pharmaceutical preparations.
Soya Lecithin are natural surfactants, which can be used as drug excipients to improve the water dispersion and oral bioavailability of drugs. Soya Lecithin can also be used in bile salt micellar system to improve drug loading and micellar stability. Soya Lecithin, as emulsifier and solvent enhancer, are the most common liposome excipients, which are used to prepare specific drug carriers and make drugs targeted.
