Abstract

The authors present in this review the in vitro and in vivo effects of rosmarinic acid, which is an ester of caffeic acid and 3,4-dihydroxy-phenyllactic acid. This phenolic acid belongs to the group of non-flavonoid polyphenols. These molecules are synthetized by plants as secondary metabolites in response to various stressful stimuli. The plants of Lamiaceae family such as common thyme, lemongrass, rosemary and sage contain high proportion of this substance. In this review rosemary and the common thyme are presented in details as these two species were usually used for in vivo experiments. Besides the rosmarinic acid, these two plants contain a lot of flavonoid and non-flavonoid type molecules in their volatile oils or in their other extracts, which have beneficial effects on human and animal health. It is widely known that the phenolic ring can act as proton and hydrogen donator, which can render this molecule antioxidant characteristic. Antitumor, antimicrobial, anti-inflammatory, gastro- and hepato-protective effects of rosmarinic acid in aglycon form were successfully proven in in vitro experiments using cell line models or tissue cultures. In the nature, however, rosmarinic acid is present in glycosylated form; therefore the results of the in vivo experiments differ from the in vitro data. Studies using farm animals did not apply rosmarinic acid only, but different plant parts or extracts, which involve rosmarinic acid among other active compounds. The application of these rosmarinic acid containing herbs could contribute to the efficient antioxidant defence mechanism in rabbits. Rosmarinic acid appeared to promote elevated growth rate in chickens and provide better quality of meat in broilers. In general, rosmarinic acid in combination with other substances could also improve cholesterol and triglyceride profiles and support antioxidant capacities against oxidative stress in livestock.
