Rosmarinic Acid is an ester of caffeic acerbic and 3,4-dihydroxyphenyllactic acid. It is
frequently begin in breed of the Boraginaceae and the subfamily Nepetoideae of
the Lamiaceae. However, it is aswell begin in breed of added college bulb
families and in some bracken and hornwort species. Rosmarinic Acid has a amount
of absorbing biological activities, e.g. antiviral, antibacterial, antiinflammatory
and antioxidant. The attendance of rosmarinic Acid in alleviative plants, herbs
and spices has benign and bloom announcement effects. In plants, rosmarinic
Acid is declared to act as a preformed constitutively accumulated defence
compound. The biosynthesis of rosmarinic Acid starts with the amino acids
L-phenylalanine and L-tyrosine. All eight enzymes complex in the biosynthesis
are accepted and characterised and cDNAs of several of the complex genes accept
been isolated. Bulb corpuscle cultures, e.g. from Coleus blumei or Salvia
officinalis, accrue rosmarinic Acid in amounts abundant college than in the
bulb itself (up to 36% of the corpuscle dry weight). For this acumen a
biotechnological assembly of rosmarinic Acid with bulb corpuscle cultures has
been proposed.
