Difference in variety and area in terms of general content of flavones in bee pollens

79 batches of bee pollen that belonged to 15 varieties collected from 23 provinces all over the country during the year of 2008 ～ 2011 were tested for general content of flavones using optimized spectrophotometer. Results of the tests showed that the general content of flavones were in range of 0.49% ～ 3.49% . Among the 15 varieties, cole’s was the highest in terms of general content of flavones ( to be 3.15% in average) , rose’s and Schisandra’s were the second and the third high ( to be 2.20% and 2.04% , respectively, in average) , and sesame’ s was the one that was minimum in terms of general content of flavones ( to be 0.52% in average) . Statistic analysis indicated that general content of flavones differed among the provinces or /and the years in which the pollens were collected but the extent of difference was trivial within a given variety.Regardless of the variety and the year in which it was collected, the pollen reached its highest in terms of general content of flavones in Qinghai ( to be 2.91% in average) , its second and third high in Xinjiang and Guangdong ( to be 2.55% and 1.93% in average) , respectively, and its least in Heilongjiang and Hainan ( both to be 0.64% in average) .The difference was insignificant, however, from statistic point of view.
