Rosmarinic acid, found in various plants, exhibits antiviral, antibacterial, anti-inflammatory, and antioxidant properties. Plant cell cultures offer a promising biotechnological method for its high-yield production.

Area of Science:

  • Phytochemistry
  • Plant Biotechnology
  • Natural Products Chemistry

Background:

  • Rosmarinic acid is a phenolic compound derived from caffeic acid and 3,4-dihydroxyphenyllactic acid.
  • It is widely distributed in plants, including Boraginaceae, Lamiaceae, and other families, as well as ferns and hornworts.
  • This compound possesses significant biological activities such as antiviral, antibacterial, anti-inflammatory, and antioxidant effects, contributing to the health benefits of medicinal plants, herbs, and spices.

Purpose of the Study:

  • To explore the biosynthesis, biological activities, and potential for biotechnological production of rosmarinic acid.
  • To highlight the role of rosmarinic acid as a plant defense compound.
  • To investigate the accumulation of rosmarinic acid in plant cell cultures for enhanced production.

Main Methods:

  • Literature review on rosmarinic acid distribution, biosynthesis pathways, and biological activities.
  • Analysis of plant species known to contain rosmarinic acid.
  • Examination of studies on plant cell culture accumulation and biotechnological production strategies.

Main Results:

  • Rosmarinic acid is synthesized from L-phenylalanine and L-tyrosine, involving eight known enzymes.
  • Plant cell cultures, such as those from Coleus blumei and Salvia officinalis, can accumulate rosmarinic acid at concentrations up to 36% of cell dry weight.
  • This accumulation is significantly higher than in the parent plants, indicating potential for large-scale production.

Conclusions:

  • Rosmarinic acid's diverse biological activities and health benefits are well-documented.
  • Plant cell culture technology presents a viable and efficient biotechnological approach for the high-yield production of rosmarinic acid.
  • Further research into optimizing plant cell culture conditions could enhance rosmarinic acid yields for industrial and pharmaceutical applications.
