OBJECTIVE
To study the chemical constituents from the leaf of Bombax ceiba.
METHODS
The compounds were isolated and purified with silica gel and Sephadex LH-20 column chromatography. Their structures were determined on the basis of physicochemical properties and spectroscopic analysis.
RESULTS
Eleven compounds were isolated and identified as taraxeryl acetate (1), squalene (2), taraxerone (3), beta-sitosterol palmitate (4), taraxerol (5), 4-methyl stigmast-7-en-3-ol (6), 1H-indole-3-carboxylic acid (7), 6-O-palmitoylsitosteryl-D-glucoside (8), 12beta-hydroxyl-pregnane-4, 16-diene-3, 20-dione (9), loliolide (10) and 5-(hydroxymethyl) furfural (11).
CONCLUSIONS
All the compounds are isolated from this genus for the first time.
