Yang Hai-rong and Wang Sheng-xiu   

Abstract: Rhododendron dabanshanense is a new species of Rhododendron. The clinical studies on the treatment of chronic bronchitis patients show that the aqueous extracts of Rhododendron dabanshanense have relatively curative effect. Four phenolic components have been isolated from the plant and identified as betuligenol, betuloside, quercetin and quercetin-3-arabinoside respectively, according to m.p., UV, IR, MS and NMR spectra. Except quercetin, the three others are not isolated so far from Rhododendron in China.
