What is Rosmarinic Acid ?
Rosmarinic acid is a natural phenolic acid compound formed by the condensation of
caffeic acid and 3,4-dihydroxyphenyllactic acid. Rosmarinic acid is
relatively stable and appears as a white to brown solid. It is
primarily found in various plants, including the Lamiaceae,
Boraginaceae, Cucurbitaceae, Tiliaceae, and Apiaceae families. Its
content in Perilla leaves can reach 20% (w/w).
