Cysteine sulfoxide derivatives in Petiveria alliacea

Two diastereomers of S-benzyl- l-cysteine sulfoxide have been isolated from fresh roots of Petiveria alliacea. Their structures and absolute configurations have been determined by NMR, MALDI-HRMS, IR and CD spectroscopy and confirmed by comparison with authentic compounds. Both the R S and S S diast...

Zusammenfassung:	Two diastereomers of S-benzyl- l-cysteine sulfoxide have been isolated from fresh roots of Petiveria alliacea. Their structures and absolute configurations have been determined by NMR, MALDI-HRMS, IR and CD spectroscopy and confirmed by comparison with authentic compounds. Both the R S and S S diastereomers of the sulfoxide are present in all parts of the plant (root, stem, and leaves) with the latter diastereomer being predominant. Their total content greatly varied in different parts of the plant between 0.07 and 2.97 mg g −1 fr. wt, being by far the highest in the root. S-Benzylcysteine has also been detected in trace amounts (
