Unsymmetrical trisulfides have biological significance several have been isolated from plants of the onion family, e.g. allyl propyl trisulfide. Interest in this class of compound was stimulated by the discovery of a biologically active compound shown to be the trisulfide (74) (Figure 2) isolated from the tropical plant Petiveria alliacea found in Africa and other countries.5 The trisulfide (74) shows insecticidal and antimicrobial activity.
