Aloe vera (L.) Webb.: Natural Sources of Antioxidants - A Review

Plant Foods Hum Nutr. 2019 Sep;74(3):255-265. doi: 10.1007/s11130-019-00747-5.


Many studies have proved that bioactive components of Aloe vera have an anti-inflammatory effect and support lipid and carbohydrate metabolism, helping to maintain normal sugar and cholesterol levels in blood and normal body weight. When aloe is applied externally, it accelerates the regeneration of the damaged skin. Aloe contains antioxidants, which may increase the shelf-life and nutritional value of food; therefore, it is widely used in cosmetic, pharmaceutical and food industry. An antioxidant activity was shown for leaf's skin, flowers and gel of aloe. In this work the future of A. vera as effective antioxidants is primarily discussed and expected trends are summarised. Furthermore, the bioactive components and the health-promoting effects of A. vera are investigated.

Keywords: Aloe vera; Antioxidative activity; Bioactive components; Natural antioxidants.
