**2.4 Isoprenoids**

Squalene is an isoprenoid component that has six isoprene units and antioxidant activity and is widely produced in buckwheat plants. Squalene protects cells from radicals, strengthens the immune system, and reduces the risk of various types of cancer. There are some differences between buckwheat species, especially in the content of squalene and rutin [73].
