The increasing importance of multi-resistant strains and microbial biofilms in the development of chronic infections has driven the search for more effective alternative therapy including plant-origin preparations. The present study evaluates the broadly-defined antimicrobial activity of two
A phytochemical study has been carried out on the aerial parts of Salvia pachyphylla and S. clevelandii. From S. pachyphylla, the known diterpenes carnosol (2), rosmanol, 20-deoxocarnosol (3), carnosic acid, isorosmanol (4), 7-methoxyrosmanol, 5,6-didehydro-O-methylsugiol (5),
The biomass and concentration of bioactive quinone methide-type diterpenes in hairy roots of Salvia austriaca were determined and compared with levels of these metabolites in roots of field-grown plants. The cultures were maintained in shake flasks and a nutrient sprinkle bioreactor. Diterpene
Using various chromatographic methods, a new hexacyclic triterpenoid, 2β,3β,24β-trihydroxy-12,13-cyclotaraxer-l4-en-28oic acid (1), together with ten known compounds, 2α,3α,23-trihydroxyurs-12,20(30)-dien-28oic acid (2), 6,7-dehydroroyleanone (3), horminone (4), 7-O-methylhorminone (5), sugiol (6),
