Introduction. Measurement of physicochemical parameters is an initial step toward quality assessment of herbal raw materials. This study describes selected characteristics of Dendrostellera ammodendron aerial parts collected in southern Kazakhstan.
Objective. To provide a preliminary description of selected physicochemical parameters of Dendrostellera ammodendron aerial parts collected in the Turkistan Region, Kazakhstan.
Methods. Aerial parts collected near Shardara during flowering in June 2026 were analyzed for sieve fractions, loss on drying, total ash, acid-insoluble ash, foreign matter and the dry residue obtained with six solvents. Each solvent extraction was performed once (n=1).
Results. Mean total ash was 2.20 ± 0.20% (n=5), and the reported mean acid-insoluble ash was 0.461%. Recalculation of loss on drying from the recorded initial and final masses yielded 6.27 ± 1.75% (n=5); one drying sequence showed an inconsistent mass trajectory. Dry-residue masses for the tested solvents ranged from 0.06 to 0.63 g. Percentage extractive yields could not be reliably determined without aliquot-volume data.
Conclusion. The measurements provide a preliminary description of selected physicochemical quality parameters. Confirmation of botanical identity and analysis of independent batches are necessary before establishing general raw-material quality specifications.
