Phytochemical

Red, blue, and purple colors of berries derive mainly from polyphenol phytochemicals called anthocyanins.
Cucurbita fruits, including squash and pumpkin, typically have high content of the phytochemical pigments called carotenoids.

Phytochemicals are chemical compounds produced by plants, generally to help them resist fungi, bacteria and plant virus infections, and also consumption by insects and other animals. The name comes from Greek φυτόν (phyton) 'plant'. Some phytochemicals have been used as poisons and others as traditional medicine.

As a term, phytochemicals is generally used to describe plant compounds that are under research with unestablished effects on health, and are not essential nutrients. Regulatory agencies governing food labeling in Europe and the United States have provided guidance for industry to limit or prevent health claims about phytochemicals on food product or nutrition labels.
