Infobox references

Mesquitol is a flavan-3-ol, a type of flavonoid.^[1]

Prosopis juliflora, a mesquite found in Kenya, shows unusual amount of (-)-mesquitol from 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]
