| Abstract |
Medicinal plants are very important in sustainable economic development, in the pharmaceutical industry and in promoting the conservation of biodiversity. The main objective of this work was to obtain extracts and hydrolytes of flowers, leaves and bark of Sambucus nigra, and analyse their possible uses. Two sampling areas in a field were chosen, and collection was carried out at different times, according to the selected parts of the plant. Two techniques were chosen, steam distillation and ethanol and glycerol extraction. The hydrolytes of the different parts of Sambucus nigra can be used in therapeutic applications due to their pH. Distillations of the stems and leaves gave no indication of essential oil, at least with the quantities used. Therefore, the highest percentage of essential oil was found in the flowers. Ethanol was a better extraction solvent than glycerine, with yields of 99% and 90%, respectively. Flower extracts prepared with ethanol showed a total phenolic content of 59.3 +/- 2 mg gallic acid equivalent/g and a total flavonoid content of 16.2 +/- 0.2 mg quercetin equivalent/g. This research could contribute to the valorisation of this species giving a boost to its reuse from a circular economy perspective. |
