What are types of phytochemicals?
Generally, phytochemicals have been classified into six major categories based on their chemical structures and characteristics.

Phytochemicals are precious for human nutrition. Indoles, isothiocyanates, and sulforaphane from vegetables, such as broccoli, alylic sulfides from onions and garlic and isoflavonoids from soybeans are known as plant phytochemicals.
What is the meaning of phytochemical?
Phytochemicals are defined as bioactive nutrient plant chemicals in fruits, vegetables, grains, and other plant foods that may provide desirable health benefits beyond basic nutrition to reduce the risk of major chronic diseases (Liu, 2004).
What are the three types of phytochemicals?
There are three major groups of phytochemicals:
- Polyphenols – subcategorised as the flavonoids, phenolic acids and other non-flavonoid polyphenols.
- Terpenoids – subcategorised as the carotenoids and non-carotenoid terpenoids.
- Thiols – includes the glucosinolates, allylic sulfides and non-sulfur containing indoles.
