-Two series of 3-sulfanylalkyl alkanoates were discovered in a peel extract of fruits of wild-growing Poncirus trifoliata (L.) Raf. (Rutaceae). The alkanoates of 3-methyl-3-mercaptobutanol and 3-mercaptohexanol are members of a family of potent odorants having in common a 1,3-positioned O,S moiety. \\+Two series of 3-sulfanylalkyl alkanoates were discovered in a peel extract of fruits of wild-growing Poncirus trifoliata (L.) Raf. (Rutaceae). The alkanoates of 3-methyl-3-mercaptobutanol and 3-mercaptohexanol are members of a family of potent odorants with tropical fruity and sulfury notes 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." \\ "The alkanoate residues comprise all even-numbered saturated fatty acids from C2 (acetate) to C18 (octadecanoate).
