Methyl-heptenone combines with sodium bisulphite. On reduction by means of sodium and alcohol, it forms the corresponding alcohol, methyl-heptenol, CgHj OH, which has the following characters —... 

The aroma volatiles of honeybush have also been reported by Wang et al (27). The aroma components were dominated by monoterpene alcohols, of which a-terpineol (28%) was the major component, with minor amounts of linalool (7%), nerol (2%) and geraniol (8%). These monoterpenes are responsible for the sweet, floral and fruity notes of the tea, while other components such as phenylethyl alcohol (3%) and 5-methylfurfural (2.1%) imparted also sweet and honey notes. Other volatiles such as eugenol (6%), linalool oxides (7%), and methyl-heptenol (3%) were also detected. With both honeybush and rooibos, the exact nature of the aromas and flavor will depend significantly on the species collected, time of collection, drying, fermentation and processing (27). 

Schimmel Co. have isolated dsxtro-a-terpineol from the oil, and also an alcohol not previously found naturally, which they identified as methyl-heptenol. This body has the following characters —... 

East Indian lemongrass oil contains normally citral as its major component in a 70-85% concentration. Other components include geraniol and methyleugenol as well as many of the compounds present in the West Indian oil (e.g., dipentene, myrcene, methyl-heptenol, famesol, -decanal, guanic acid, and others).
