Abstract

Nepeta ucrainica L. is used as a herbal tea in Kazakhistan. Phytochemical investigations of the aerial parts of the plant resulted in the isolation of verbascoside (1) and 1,5,9-epi-deoxyloganic acid (2). The structures of the compounds were elucidated by spectral (UV, IR, H-1-NMR and C-13-NMR) methods and HPLC analysis. The in vitro immunomodulatory activity of verbascoside was investigated by assessing neutrophil function; chemotaxis and intracellular killing activity. Verbascoside showed an increased chemotactic activity in all doses applied compared with the medium used as a negative control and had a positive effect on respiratory burst of neutrophils, but there was an opposite effect with increasing doses, pointing to a possible suppression of neutrophil intracellular killing activity.
