What is Aloin?

Aloin, also known as aloin, is a yellow solid that is naturally occurring and belongs to the anthraquinone class of organic compounds. Anthraquinones are the main active ingredients found in aloe vera. Aloin contains aloe glycoside, which has special physiological and biological effects. It can help eliminate toxins from the body, cleanse the blood, improve blood vessel flexibility, lower blood pressure and viscosity, and enhance blood circulation. These actions can prevent conditions such as arteriosclerosis and cerebral hemorrhage.

Aloin Uses

External skin care: Aloe glycoside has the effects of calming, moisturizing and repairing the skin, and can be used to treat skin problems such as sun exposure or burns, eczema, and acne.

Anti-inflammatory and analgesic: Aloe glycoside has a certain inhibitory effect on bacteria and can be used to treat minor skin infections and inflammation.

Laxative: Aloe glycoside helps increase intestinal peristalsis, promotes defecation, and can be used to relieve constipation problems.

Improves the immune system: Aloe glycosides can enhance the body’s immunity and help the body fight against viral and bacterial infections.

Aloin Biological Activity

The controversial aspect of aloe glycoside in relation to food safety centers around the anthraquinone laxative found in aloe glycoside. This substance is primarily present on the inner surface of the leaf skin and plays a crucial role in many of the beneficial functions of aloe vera. It is known for its stomach-soothing, laxative and diuretic properties, as well as its potential beauty benefits such as detoxification, sterilization, and tumor inhibition. However, studies in toxicology have shown that in vitro tests have demonstrated the ability of aloe glycoside to induce gene mutations in bacteria and mammalian cells. This is because when aloe glycoside is oxidized, it can convert into aloe-emodin, which has a similar structure to emodin and contains the mutagen 1,8-dihydroxyanthraquinone, known to pose risks of cancer and kidney damage.

Therefore, the safe consumption of aloe glycoside depends on the amount of aloin present in the product. However, variations in aloe vera varieties, leaf maturity, harvest timing, and processing methods can result in varying levels of aloin content in the final products.

Aloin Identification Method

Take 0.5g of aloe vera and mix it with 50ml of boiling water. Add a small amount of diatomaceous earth to the mixture and then filter it. The resulting filtrate can be used for the following tests:

(1) Borax test: Take 5ml of the filtrate and add 0.2g of borax. Heat the mixture until the borax dissolves and then add a few drops of the solution to 10ml of water. A green fluorescence will appear, known as the schnetern reaction. This fluorescence is caused by the hydrolysis of barbaloin by borax, which produces anthrone derivatives.

(2) Bromine water test: Add an equal amount of freshly prepared bromine saturated solution to 2ml of the filtrate. A yellow precipitate, known as tetrabromaloin, will form.
