Aloe mucopolysaccharide, an ingredient used in health products and functional cosmetics
The mucopolysaccharides (MPS) or acemannan in aloe gel are beneficial to human being, but they are heat-sensitive and unstable compounds. Standard commercial aloe juice production is a complicated and expensive process. Currently there are many cheap, diluted or faked aloe juices on market.
Nature, functions and indications of aloe: Bitter, cold, non-toxic, go through the liver, heart, spleen; used for the treatment of both diarrhea and constipation (antibacterial and laxative), indigestion, headache, red eyes, convulsions, diabetes, cardiovascular diseases, parasitic abdominal pain, scabies, hemorrhoids, croton poison, infantile malnutrition and ringworm.
Major pharmacological effects of aloe:
- Anti-inflammatory, antibacterial
- Enhance skin elasticity, moisturize skin and prevent aging
- Prevent freckles and wrinkles
- Cleanse skin, anti-sebum, prevent suppurative skin
- Reduce dandruff, promote hair growth
- Protect skin and mucous membranes, prevent acne
The varying sizes of aloe mucopolysaccharides determine their healing properties:
- Small (50-600 mono-sugar molecules): Reduces inflammation which is involved in such diseases as ulcerative colitis, arthritis and gastric reflux, also helps with the reduction of blood sugar with both type I and II diabetes.
- Medium (up to 1,500 mono-sugar molecules): Prevents and treats arteriosclerosis, heart disease and Parkinson’s disease.
- Large (up to 5,000 mono-sugar molecules): Anti-bacterial and anti-viral effect
- Very large (up to 9,000 mono-sugar molecules): Healing effect on AIDS, cancer and many different immune system disorders.
Scientists have found that the yield of MPS from aloe whole leaf is more than the MPS yield from aloe inner gel; the quality and health effects from both sources have no much difference.
True and high quality aloe gel powder should be manufactured at low temperature by using charcoal filtration to remove aloin and aloesin, and freeze- or spray-drying to keep MPS intact.
Quite many aloe juices on market are produced by using very little true aloe MPS powder or removing bitter taste compounds and laxative aloin by heating which causes MPS decompose, or using non-purified aloe gel and dilution to make aloin lower than 1 ppm, or/and using additives such as organic acids and maltodextrin as faked aloe gel.
In last few years, scientists have found a very specific method to distinguish aloe whole leaf gel from maltodextrin and aloe inner gel by using NMR spectrum technology, and using isocitrate and isocitrate lactone as aloe whole leaf gel markers (MLM) for aloe product quality control.
Other bio-active components in Aloe: Aloe emodin, aloe-emodin glycosides, aloin or barbaloin, homonataloin, chrysophanol, chrysophanol glucoside, anthracene and its glycosides, quercetin, camherenol, rutin, glucuronic acid. Aloe also contains arginine, asparagine, glutamic acid, eight essential amino acids (lysine, leucine, threonine, isoleucine, phenylalanine, valine), campesterol, sitosterol, potassium, sodium, copper, zinc, chromium and other more than twenty kinds of inorganic elements. vitamin B1, folic acid, vitamin B2, Vitamin C, nicotinamide, vitamin E, vitamin B6, Vitamin A and choline.
