The pigment in colored cotton fibers was extracted by methanol at room temperature. The results of color reactions HCl-Mg reaction, NaBH4 reaction, NaOH reaction, FeCl3 reaction and Pb(Ac2 reaction of the pigment extractive showed that the pigment extracted by methanol was flavone or flavonol with two adjacent hydroxide groups (Table 2, Fig. 1). The results of UV spectral analysis further proved that the pigment extracted by methanol from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring, and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring and indican replaced a hydroxide group at 3-site of A ring Fig.
