Allistatin is the collective name for two chemicals, allistatin I and allistatin II, which may be found in garlic.[1] There is no conclusive evidence of its existence, or the existence of the related compound garlicin.[2] It is a sulfur-free chemical and plays an active role within garlic.[3][4] It is most likely a flavonoid.[1]
There is no experimental evidence of the structure of allistatin;[5] some studies claim it is similar to cyanidin, while others found it shared similarities with garlicin (but not allicin).[5]
