Background. R. rosea L. is a valuable medicinal plant. Due to its precious properties it is intensively collected and is on the verge of extinction. The active components, such as rosavin and salidroside, accumulate mainly in the rhizomes, having adaptogenic, antioxidant and other properties. Objective of the study. Determination of rosavin and salidroside content in ethanolic extracts from rhizomes of R. rosea plants in the Carpathian population, Romania. Material and Methods. Ethanolic extracts (40-70% EtOH) were analyzed by thin-layer chromatography (CSS) and UV-VIS spectrometry at λmax 254 and 276 nm wavelengths, recalculated to rosavin and salidroside. Results. The intensity of the Rf bands characteristic of rosavin and salidroside in the chromatogram of the extract in the 40% ethyl alcohol solution was the higherst. compared to that characteristic of other extracts. Increasing the concentration of ethyl alcohol from 40% to 50, 60 and 70% led to a gradual decrease in the intensity of all components. The results obtained by UV-VIS spectrometry reveal that the rosavin content in R. rosea rhizome extracts is 1.25 ± 0.19% and salidroside 1.53 ± 0.98%. Conclusion. Therefore, rosavin and salidroside are best extracted in 40% ethyl alcohol, and the content of active ingredients in rhizomes collected in the Carpathian Mountains, Romania, falls within the characteristic data for R. rosea rhizomes collected in other regions of the Earth. |
