[Meth付] The pig- ment contents and antioxídant property of shell of several natural colorful coc∞n varieties were determined. [Result] The content of flavonoid in green cocoons w;嗣 the híghest (0.521 mg/g) , which was 4. 65 times as that in white coc∞ns. The content of flavonoid in yellow coc∞ns w;皿 the 回cond and 由at in white coc∞ns and red coc∞ns. The content of carotenoid in yellow coc∞ns and red cocωns were all more than O. 5 mg/g , which was 8 times higher than white coc∞ns. In addition , the antioxidant activity in green coc∞ns w町e the highest (217.5 U/g) , followed hy that in yellow coc∞ns. The antioxidant activity in white coc∞ns and red coc∞ru; was lower. [Conclusion] Compared with white coc∞血， green coc∞ns had higher content of flavonoid , and yellow cOC∞ru
