Rosmarinic acid, named after rosemary (Salvia rosmarinus Spenn.), is a polyphenol constituent of many culinary herbs, including rosemary (Salvia rosmarinus L.), perilla (Perilla frutescens L.), sage (Salvia officinalis L.), mint (Mentha arvense L.), and basil (Ocimum basilicum L.). [1]
Rosmarinic acid was first isolated and characterized in 1958 by the Italian chemists Scarpatti and Oriente from rosemary ( Salvia rosmarinus), [2] after which the acid is named.
Chemically, rosmarinic acid is a caffeic acid ester, with tyrosine providing another phenolic ring via dihydroxyphenyl- lactic acid. [1] It has a molecular mass of 360 daltons. [1]
Rosmarinic acid accumulation is shown in hornworts, in the fern family Blechnaceae, and in species of several orders of mono- and dicotyledonous angiosperms. [3]
It is found most notably in many Lamiaceae (dicotyledons in the order Lamiales), especially in the subfamily Nepetoideae. [1] [4] It is found in species used commonly as culinary herbs such as Ocimum basilicum (basil), Ocimum tenuiflorum (holy basil), Melissa officinalis (lemon balm), Salvia rosmarinus ( rosemary), Origanum majorana ( marjoram), Salvia officinalis (sage), thyme and peppermint. [1] [5] It is also found in plants in the family Marantaceae (monocotyledons in the order Zingiberales) [3] such as species in the genera Maranta ( Maranta leuconeura, Maranta depressa) and Thalia ( Thalia geniculata). [6]
Rosmarinic acid and the derivative rosmarinic acid 3′-O-β-D- glucoside can be found in Anthoceros agrestis, a hornwort (Anthocerotophyta). [7]
The biosynthesis of rosmarinic acid uses 4-coumaroyl-CoA from the general phenylpropanoid pathway as a hydroxycinnamoyl donor. [1] The hydroxycinnamoyl acceptor substrate comes from the shikimate pathway: shikimic acid, quinic acid and 3,4-dihydroxyphenyllactic acid derived from L-tyrosine. [3] Thus, chemically, rosmarinic acid is an ester of caffeic acid with 3,4-dihydroxyphenyllactic acid, but biologically, it is formed from 4-coumaroyl-4′-hydroxyphenyllactate. [8] Rosmarinate synthase is an enzyme that uses caffeoyl-CoA and 3,4-dihydroxyphenyllactic acid to produce CoA and rosmarinate. Hydroxyphenylpyruvate reductase is also an enzyme involved in this biosynthesis. [9]
When extracted from plant sources or synthesized in manufacturing, rosmarinic acid may be used in foods or beverages as a flavoring, in cosmetics, or as a dietary supplement. [1]
