Abstract
The determination of general parameters (loss on drying test, total ash, and ash insoluble in dilute HCl) as well as the determination of total phenols content (TPC) and total flavonoids content (TFC) were determined in the aerial part of Sideritis scardica and S. raeseri collected in different localities in North Macedonia and Albania. In the analyzed samples of S. scardica and S. raeseri loss by drying was 6.65-8.01% and 7.08-8.42%, the content of total ash was 4.91-7.41% and 4.72-7.74%, while the content of total ash insoluble in diluted HCl was 0.13-0.27% and 0.05-0.75%, respectively. The amounts of phenolics content and total flavonoids were determined spectrophotometrically by Folin-Ciocalteu and aluminium chloride methods, respectively. The TPC was expressed as gallic acid per gram of dried plant material (mgGA/g). The TPC in S.scardica and S. raeseri ranged from 48.13±0.47 mgGA/g to 49.21±0.41 mg GA/g and from 46.7±2.53 mgGA/g to 47.98±0.8 mgGA/g, respectively. The TFC was expressed as mg Quercetin of dried plant material (mgQE/g). The TFC ranged from 7.883±1.35 mgQE/g to 17.452±0.73mgQE/g in S. scardica and from 8.775±0.29 mgQE/g to 15.979±0.45 mgQE/g in S.raeseri.
