Olive Leaf Extract is a botanical ingredient derived from the leaves of Olea europaea L., the olive tree, a well-known evergreen species in the Oleaceae family. The leaves are typically silvery green, oblong in shape, and commonly measure 4–10 cm in length and 1–3 cm in width. As a plant extract with a long history in traditional use and modern nutraceutical development, Olive Leaf Extract has gained strong interest from manufacturers of dietary supplements, functional foods, cosmetics, and natural health products.
What Makes Olive Leaf Extract Valuable?
The most widely recognized bioactive constituent in Olive Leaf Extract is oleuropein, a bitter iridoid glycoside that is considered the key marker compound for quality and standardization. Another important component is hydroxytyrosol, which is also valued in botanical formulation and product development. In addition to these compounds, olive leaves naturally contain a complex profile of phenolic substances, including flavonoids, glycosides, and tannin-related compounds, which contribute to the extract’s overall functional profile.
Because of this composition, Olive Leaf Extract is commonly selected as a broad-spectrum botanical ingredient for oral supplements and topical formulations. For B2B buyers, the value of this ingredient lies in its plant origin, standardized actives, and compatibility with a wide range of formulations.
Botanical Source and Raw Material Profile
Olive Leaf Extract is produced from the leaf material of the olive tree, a species cultivated in many regions of the world. The raw leaves are harvested and processed under controlled manufacturing conditions to help preserve the natural phenolic content and maintain batch-to-batch consistency.
