Ursolic acid

Ursolic acid is a naturally occurring triterpenoid compound found in various plants, including apple peels, basil, cranberries, peppermint, and oregano. It is known for its potential health benefits, which include anti-inflammatory, antioxidant, and anticancer properties.

Sources

Ursolic acid is present in a wide variety of plants, but it is most notably concentrated in the waxy coatings of apple peels. Other significant sources include herbal plants such as holy basil, lavender, thyme, hawthorn, and prunella vulgaris. The compound is commonly extracted from these plants for use in various supplements and cosmetic products.

Structure and Properties

Ursolic acid is a pentacyclic triterpenoid that adopts a ring structure typical of its class. It is closely related to oleanolic acid, differing only in the position of one methyl group. This compound is hydrophobic in nature, which contributes to its role in the plant cuticle as a protective barrier against environmental stressors.
