Abstract:
The constituents of the leaves of the Chinese medicine Ji-jiao-du-juan (Rhododendron latoucheae Franch.)collected in Zhe-Jiang province were investigated. The extract of the leaves has a curative effect on chronic bronchitis. Three crystalline substances, quercetin, quercitrin and hyperin, were isolated from the ethanol extract and were identified separately by UV. IR. NMR and Tlc. The spectral analysis of these substances were in accord with those of the authentic samples.
