| Abstract: | A mixed dusulfide of S-(2-carboxy-3-mercaptopropyl)-l-cysteine and 3-mercaptoisobutyric acid and the disulfide of S- (2-carboxy-3-mercaptopropyl)cysteine, not previously known in nature, have been isolated from asparagus (Asparagus officinalis) shoots. The former was converted to the latter by reduction with zinc powder in HCl followed by reoxidation with aeration. |
