ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of the bee-collected rape pollen.</p><p><b>METHOD</b>The compounds were isolated by column chromatography on silica gel; Sephadex LH-20 and C18. Their structures were elucidated on the basis of spectral analysis.</p><p><b>RESULT</b>Nine compounds were isolated from the bee-collected rape pollen and the structures of them were kaemferol-3-O-beta-D-glucosyl-(2-->1)-beta-D-glucoside (1), kaemferol-3,4'-di-O-beta-D-glucoside (2), quercetin-3-O-beta-D-glucosyl-(2-->1)-beta-D-glucoside (3), nicotinic acid (4), nicotinamide (5), trans-p-coumaric acid-4-O-beta-D-glucopyranoside (6), kaemferol (7), beta-sitosterol (8) and 5-hydroxymethylfurfural (9).</p><p><b>CONCLUSION</b>Compounds 1-6 were isolated from the bee-collected rape pollen for the first time.</p>
