Objective: To compare the total flavonoids content in Epimedii folium processed by monlton suet from different growing areas and different positions of sheep or goat. Method: Twenty batches of monlton suet were collected. The processed pieces of Epimedii follum were processed by monlton suet from two species(sheep and goat)

different growing region(Ningxia Province and other provinces)

different positions of animals(in the abdomen or in the tail). The total flavonoids content in the processed pieces was determined by UV. Icariin was used as an external standard. The detection wavelength was set at 270 nm. Result: The linear range was 0.63-20.2 mg·L-1 for icariin

the average recovery was 100.08% and RSD was 1.50%(n=6). The largest reduction rate was from the growing region of Neimenggu Province

and the smallest one was from Hei long jiang of sheep's oil. The reduction rates of different species and positions were similar in the same region. The t test was applied to the measurement data with SPSS software. The results showed that the difference was very significant between the content of sample in Ningxia Province and in Neimenggy Province

Jiangxi Province

Heilongjiang Province (P<0.01). The results showed that the difference was significant between the content of sample in Ningxia Province and in Tianjin

Guangxi Province (P<0.05). The results showed that there was no significant difference between Ningxia Province and Shanghai

Hebei Province

Shandong Province

Henan Province

Fujian Province. Conclusion: The results showed that the content of total flovoids in processed pieces was effected by sheep's from different growth regions to a certain extent

species and positions no significant influence.
