Mesquitol is a flavan-3-ol, a type of flavonoid.[1]
Prosopis juliflora, an invasive New World mesquite now found in Kenya, has unusually high levels of (−)-mesquitol in its heartwood.[2]
Mesquitol, with its pyrogallol-type A-ring, is more susceptible to quinone formation at this ring, leading to aryl–aryl bond formation at carbon 5. The structural moieties constitute the proteracacinidin class of proanthocyanidins.[3] Mesquitol-(5→8)-catechin atropisomers can be isolated from Prosopis glandulosa.[4]
