title: Unexpected Irregular Monoterpene "Yomogi Alcohol" in the Volatiles of the Lathyrus L. species (Leguminosae) of Cyprus.
abstract: Lathyrus species including L. ochrus and L. sativus are known for their food, feed and horticultural uses. Despite their widespread uses and cultivation, there is limited information on their chemistry. Previously, only the essential oil composition of L. rotundifolius, L. vernus and volatiles of L. odoratus have been reported. In the present research, volatiles of seven Lathyrus L. species, namely, L. aphaca, L. ochrus, L. cicera, L. sativus, L. gorgonei, L. saxatilis and L. blepharicarpos var. cyprius were analyzed by SPME GC-MS for the first time. Plant materials were collected from five different locations in Cyprus (February-March 2012). The main components of L. aphaca volatiles from four locations were yomogi alcohol 26.1-16.5%, camphor 21.6-10.1%, tetradecane 14.3-0%; L. cicera from five locations were yomogi alcohol 20.3-3.0%, camphor 18.7-2.0%; L. gorgonei from two locations were yomogi alcohol 24.5-13.1%, camphor 17.1-9.0% and L. sativus was yomogi alcohol 11.4%, camphor 9.0%. Yomogi alcohol was not present as the major compound in L. ochrus (2-methyl butanoic acid 7.2%), L. saxatilis (hexanal 7.7%) and L. blepharicarpos var. cyprius ((Z)-3-hexenal 8.6%) volatiles. The volatiles of the Lathyrus species were also compared with each other quantitative and qualitatively using AHC analysis to find out differences among the species. The irregular monoterpene yomogi alcohol is reported from the Lathyrus and the Leguminosae family for the first time. The existence of yomogi alcohol in Lathyrus volatiles points out that the irregular monoterpenes are not restricted solely to Asteraceae family.
