Abstract
OBJECTIVE
To study the chemical constituents from the stems of Ilex pubescens Hook. et Am.
METHODS
The chemical constituents were isolated and purified by various column chromatographic methods with diatomite, silica gel, ODS and Sephadex LH-20. Their structures were identified on physical properties and spectroscopic methods.
RESULTS
Nine compounds were isolated and determined as luteolin(1), quercetin(2), hyperoside(3), rutin(4), 1, 5-dihydroxy-3-methyl-anthraquinone(5),3,5-dimethoxy-4-hydroxy-benzoic acid-1-O-beta-D-glucoside(6), hexadecanoic acid(7), stearic acid(8), n-tetratriacontanol(9), respectively.
CONCLUSIONS
All the compounds are isolated from this plant for the first time, and compounds 5 and 6 are isolated from this genus for the first time.
