Aloe vera pulp (inner leaf gel) contains over 75 active compounds, primarily water, polysaccharides (especially acemannan), vitamins, enzymes, minerals, amino acids, and phenolic compounds. Key bioactive compounds include aloin (anthraquinone)emodinsalicylic acid, and enzymes like bradykinase. These components provide moisturizing, anti-inflammatory, and antimicrobial properties.
Key Chemical Compounds in Aloe Vera Pulp:
- Polysaccharides: The most prominent component is acemannan (a mannose-rich polysaccharide), along with glucomannan, galactan, and cellulose. These are responsible for the gel’s moisturizing and immune-boosting properties.
- Anthraquinones/Anthrones: While more concentrated in the yellow latex, the pulp contains small amounts of active compounds like barbaloin (aloin A and B), isobarbaloin, and aloe-emodin, which are analgesic and antiviral.
- Enzymes: Contains several enzymes, including alkaline phosphatase, amylase, catalase, and bradykinase, which helps reduce inflammation when applied topically.
- Vitamins and Minerals: Rich in vitamins A, C, and E (antioxidants), along with
, folic acid, and choline. Minerals present include calcium, chromium, copper, magnesium, potassium, and zinc.
- Amino Acids and Fatty Acids: Contains 20 of the 22 required human amino acids. Fatty acids include plant steroids (cholesterol, campesterol
-sitosterol, lupeol) that provide anti-inflammatory and antiseptic effects.
- Other Compounds: Lignin (increases penetration), saponins (cleansing/antiseptic), and salicylic acid.
