RAMIREZ-MEDORIO, Nelson José et al. Chemical composition of volatiles from sugarcane leaves and pastures by gas chromatography. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.spe22, pp.129-138. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i22.1864.

This work analyzed the volatiles by obtaining extracts of green leaves of sugar cane in the mature state of eight varieties of sugarcane and of two pasture species by hydrodistillation with a Clevenger trap. The varieties of sugar cane used in this study were: CP 72-2086, MEX 69-290, RD 75-11, ITV 92-1424, MEX 79-431, L 77-50, COLPOS CT MEX 05-223, COLPOS CT MEX 05-204. The grasses evaluated were: itchgrass (Rottboellia cochinchinensis) and African star grass (Cynodon nlemfuensis). In the evaluated material three main compounds were found, these are: (Z) -3-hexen-1-ol, 1-octen-3-ol and phytol. These compounds were more representative in the varieties CP 72-2086 and MEX 69-290. The compound with greater frequency was (Z) -3-hexen-1-ol, which was present in seven varieties as well as in the two pastures evaluated. The abundance of (Z) -3-hexen-1-ol in the samples of the varieties of sugarcane varies from 20.35% to 57.36%, the greater amount of (Z) -3-hexen-1-ol was detected in African star grass with an abundance of 59.69%.
