Study on Total Flavonoid content in Different Parts from Different Kinds of Pigeonpea

To exploit the pigeonpea resources reasonably, the total flavonoids of the different parts were tested from kinds of pigeonpea. Results showed that, there was highly significant difference of flavonoid content in 23 kinds of pigeonpea, and in different parts of pigeonpea, respectively. The flavonoid contents in the leaves and flowers in different breeds were in the range of 2%-4% (except for 11M010), while the flavonoid contents in the pods were almost less than 2%. The total flavonoid content in leaves from 3 different maturity varieties of pigeonpea was 3.25%, 2.23% in pod skins, 0.84% in petiole and 0.22% in beans, these values were highly significant. Furtherly, the total flavonoid was highly significant higher in new leaves (4.21%) than in mature (2.98%) and old leaves (2.69%).
