Volatile Organic Sulfur-Containing Constituents in Poncirus trifoliata (L.) Raf. (Rutaceae)

During our screening of plant materials to find new natural fragrance and flavor ingredients, we discovered two series of 3-sulfanylalkyl alkanoates in a peel extract of fruits of wild-growing Poncirus trifoliata (L.) Raf. (Rutaceae), a species closely related to Citrus. The two series belong to alk...

description During our screening of plant materials to find new natural fragrance and flavor ingredients, we discovered two series of 3-sulfanylalkyl alkanoates in a peel extract of fruits of wild-growing Poncirus trifoliata (L.) Raf. (Rutaceae), a species closely related to Citrus. The two series belong to alkanoates of 3-methyl-3-sulfanylbutan-1-ol and 3-sulfanylhexan-1-ol, respectively, and thus are members of a family of natural molecules having in common a 1,3-positioned O,S moiety. The alkanoate residues comprise all even-numbered saturated fatty acids from C2 (acetate) to C18 (octadecanoate). Among the 20 sulfur-containing compounds identified, 14 are described for the first time as naturally occurring in a botanical species. Several cysteine-S-conjugates were synthesized as hypothetical precursors of the new volatile sulfur-containing constituents, where after S-(3-hydroxy-1,1-dimethylpropyl)-l-cysteine, S-[3-(acetyloxy)-1,1-dimethylpropyl]-l-cysteine, and S-[1-(2-hydroxyethyl)butyl]-l-cysteine were identified in the fruit peel. No cysteine-S-conjugates were detected in the fruit juice. Keywords: Poncirus trifoliata (L.) Raf.; 3-methyl-3-sulfanylbutan-1-ol; 3-methyl-3-sulfanylhexan-1-ol; 3-methyl-3-sulfanylbutyl alkanoates; 3-sulfanylhexyl alkanoates; cysteine-S-conjugates; natural occurrence; fragrance and flavor chemical
