Abstract:

In this study, superfine comminution technique was applied to destroy the spore wall of the pollen of Brassica campestris, and then the leaching rates of quercetin and kaempferol in superfine and common powdered pollens were compared by HPLC. The results showed that the leaching rates of quercetin and kaempferol in superfine pollen are higher 45.16% and 27.86% than those in common powdered pollen, respectively. In conclusion, superfine comminution technique can effectively promote the leaching rates of effective components in the pollen of Brassica campestris.

Key words: pollen of Brassica campestris, superfine comminution technique, quercetin, kaempferol
