Study on examination of pollen quality
The examination of pollen quantity in pollen raw materials is one of the important steps of quality control on raw materials. We added quantitative pollen raw materials into unit volume of PCS solution, mixed evenly and counted. Based on the count, we can calculate the pollen quantity in unit weight of pollen raw materials. Quantitative artificial raw materials with different quantity of Artemisia L. Pollen were added into unit volume of PCS solution. The results showed a significant correlation between the count and the pollen quantity in unit volume of PCS solution ( r =0.998, P 0.01). In addition the counts of sifted pollen raw material was much higher than those of unsifted ( P 0.01). The coefficient of variation repetitious counts was 8.6%.
