Nasonov includes a number of different terpenoids including geraniol, nerolic acid, citral and geranic acid. Nasonov pheromone includes a number of terpenoids including geraniol, nerolic acid, citral and geranic acid. These include cinnamaldehyde and its derivatives, citral, and lilial. These workers have large cephalic gland reservoirs of citral and chemical isomers. It also contains aromatic oils geraniol, dipentene, citral, etc. The "E"-isomer is known as geranial or citral A. Synthetically produced Nasonov consists of citral and geraniol in a 2&colon;1 ratio. Other instances of this reaction include acrolein, citral, benzal acetone, and pent-3-en-2-one. Additional rearrangements and oxidations provide compounds such as citral, citronellal, citronellol, linalool, and many others. Structures elucidated by Barbier include myrcenol, citral, linalool (also known as licareol), and puleone. The oil has the highest citral purity; typically higher than lemongrass. PP (phenylpropanoids&colon; myristicin, dillapiole, elemicin), C (citral) and a type rich in rosefuran. Citral has a strong lemon (citrus) odor. Lemon grass oil contains 65-85% citral in addition to myrcene, citronellal, citronellol, and geraniol. Citral is also used as a flavor and for fortifying lemon oil.
