Abstract:
Potato tuber skin (suberin), isolated enzymatically, was depolymerized with BF 3 ‐CH 3 OH, and the structure and composition of the aliphatic monomers were determined by combined gas chromatography‐mass spectrometry. 18‐Hydroxyoctadec‐9‐enoic acid and octadec‐9‐ene‐1,18‐dioic acid were the major components. Products of epoxidation and subsequent hydration of the Δ 9 double bond of these compounds, 10,16‐dihydroxy hexadecanoic acid, and much smaller quantities of 9,16‐dihydroxyhexadecanoic acid and 8,16‐dihydroxyhexadecanoic acid also were present. The other significant feature of the monomer composition of potato skin was that it contained substantial quantities of C 20 −C 28 fatty acids, fatty alcohols, and ω‐hydroxy acids. Based upon these studies, a method of distinguishing between suberin and cutin and a biosynthetic pathway for suberin monomers are suggested.
