Rosmarinic acid was first isolated and characterized in 1958 by two Italian chemists ML Scarpatti and G. Oriente from rosemary (Rosmarinus officinalis).
It is found most notably in many Lamiaceae (dicotyledons in the order Lamiales), especially in the subfamily Nepetoideae. It is found in species used commonly as culinary herbs such as Ocimum basilicum (basil), Ocimum tenuiflorum (holy basil), Melissa officinalis (lemon balm), Rosmarinus officinalis (rosemary), Origanum majorana (marjoram), Salvia officinalis (sage), thyme and peppermint or in plants with medicinal properties such as common self-heal (Prunella vulgaris) or species in the genus Stachys.
It is also found in other Lamiales such as Heliotropium foertherianum, a plant in the family Boraginaceae.
It is also found in plants in the family Marantaceae (monocotyledons in the order Zingiberales) such as species in the genera Maranta (Maranta leuconeura, Maranta depressa) and Thalia (Thalia geniculata).
The biosyntheses of caffeoylshikimate, chlorogenic acid and rosmarinic acid use 4-coumaroyl-CoA from the general phenylpropanoid pathway as hydroxycinnamoyl donor. The hydroxycinnamoyl acceptor substrate comes from the shikimate pathway: shikimic acid, quinic acid and hydroxyphenyllactic acid derived from l-tyrosine. Thus, chemically, rosmarinic acid is an ester of caffeic acid with 3,4-dihydroxyphenyl lactic acid, but biologically, it is formed from 4-coumaroyl-4'-hydroxyphenyllactate. Rosmarinate synthase is an enzyme that uses caffeoyl-CoA and 3-(3,4-dihydroxyphenyl)lactate to produce CoA and rosmarinate. Hydroxyphenylpyruvate reductase is also an enzyme involved in this biosynthesis.
The enzymes involved in the biosynthesis pathway probably evolved from those used in the formation of chlorogenic and caffeoylshikimic acids.
In plants, rosmarinic acid is supposed to act as a preformed constitutively accumulated defense compound.
Senescent leaves of Heliotropium foertherianum (Boraginaceae) also known as octopus bush, a plant used in many Pacific islands as a traditional medicine to treat ciguatera fish poisoning, contain rosmarinic acid and derivatives, which are known for their antiviral, antibacterial, antioxidant and anti-inflammatory properties. Rosmarinic acid may remove the ciguatoxins from their sites of action, as well as being an anti-inflammatory.
Unconjugated rosmarinic acid and its metabolites remain in the bloodstream of rats for enough time to reach the brain and decrease acetylcholinesterase activity. Rosmarinic acid may be transported in the bloodstream bound to human serum albumin and lysozyme.
