The identified constituents were 2-butenal, myrcene, ρ-cymene, limonene, cis-b-ocimene, trans-b-ocimene, linalool, ρ-mentha-1, 5, 8-triene, cis-3-hexenyl 2-methyl butanoate, and 2-furanone. Trans- b -ocimene (67.9%) was the main constituent of the oil and the major components were 2-furanone (6.2%), myrcene (6.0%), linalool (3.1%), and cis- b ... Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apple s or pineapple s. At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer.
