Summary

A microchemical approach for the identification of plant source of Chinese diuretic crude drug “Dan-zhu-ye” using low-temperature plasma ashing is reported. The specimen was ashed on a microscope slide and the remaining ashed tissue was microscopically compared with other specimens of bamboo and bamboo grasses. Characteristic distribution patterns of silicon bodies and their shape in Dan-zhu-ye have suggested that the plant source of the crude drug isLophatherum sinense Rendle or at least its very close relative.

Zusammenfassung

Über die Ergebnisse der Tieftemperatur-Veraschung der chinesischen Rohdroge “Dan-zhu-ye” zwecks pflanzlicher Zuordnung dieses Diureticums wurde berichtet. Das Untersuchungsobjekt wurde auf einem Objektträger verascht und der Geweberückstand unter dem Mikroskop mit anderen Proben von Bambus und Bambusgräsern verglichen. Charakteristische Verteilungsmuster von Siliziumkörperchen und deren Form in “Dan-zhu-ye” legen die Annahme nahe, daß die Droge von Lophatherum sinense Rendle stammt oder ihm wenigstens sehr nahe steht.
