| Abstract: | In this paper,we determinated the content of flavonoids in eucommiae pollen by spectrophotometry and use rutin as the standard sample and adopt NaNO2-Al(NO3)3-NaOH system for colouration. The egression equation of rutin standard curver is A=0.004 1 C+0.007 3,R=0.995 2. The detection of total flavonoids is at 510 nm wavelength and its level is 3.29%. |
