Ligstroside

Ligstroside is a secoiridoid glycoside found in plants of the Oleaceae family, notably in the olive tree (Olea europaea) and common privet (Ligustrum vulgare), from which its name is derived. It is a phenolic compound characterized by a specific chemical structure involving an iridoid ring system linked to a glucose moiety. Ligstroside is synthesized through plant metabolic pathways and contributes to the plant's defense mechanisms. It exists in various plant tissues, including leaves, fruits, and bark.

In the context of the olive tree, ligstroside is a significant constituent of olive leaves and is also present in unripe olives. During the processing of olives, such as for oil extraction or table olive production, ligstroside can undergo transformations or degradation. Research has explored the potential biological activities of ligstroside, including antioxidant and anti-inflammatory properties. Studies suggest it may play a role in the human diet when consumed through olive products. Its presence and concentration can vary depending on the plant species, cultivar, geographical location, and environmental conditions.
