Abstract

Aruncus dioicus (Walter) Fernald is an herbaceous plant belonging to the Rosaceae family. In the northern regions of Italy young shoots of A. dioicus are collected and used as vegetable. No studies on the chemical composition of young shoots of A. dioicus have been reported so far. Thus, the aim of the present paper was to develop and validate a comprehensive chromatographic method allowing the identification and quantification of chemical compounds occurring in A. dioicus shoots harvested at different developmental stages. The results showed that shoots contain mainly polyphenols. Twenty-four compounds were detected. Caffeoylglucose derivatives were recognized as major compounds. It was also confirmed that shoots contain the cyanogenic compound prunasin at all investigated vegetation stages. It was shown that the prunasin content significantly increases during plant development, thus justifying the belief that after the development of the first green leaves, shoots should not be used for culinary purposes any longer.
