Evaluation of cysteine sulfoxides and volatile compounds in local garlic (Allium sativum L.) and elephant garlic (Allium ampeloprasum L.) populations from northern and central Italy

Ten garlic (Allium sativum L.) and four elephant garlic (Allium ampeloprasum L.) local populations grown in northern and central Italy were evaluated for their cysteine sulfoxide and volatile compound profile. Elephant garlic showed a total sulfoxide content and a relative alliin amount significantly lower than both white and red garlic. The three groups were clearly separated by discriminant analysis of analytical data, whereas principal component analysis allowed further discrimination of garlic populations within the same type, confirming among-group differences as the main source of variability.
