A Study on Physicochemical Properties and Components of Bamboo oil from Phyllostachys nigra var. henonis by refining process

The purposes of this study were to investigate the physicochemical properties and component values of bamboo oil from Phyllostachys nigra var. henonis obtained by refining process. The tar concentration in the refined bamboo oil (RBO) was decreased to about 78% compared to crude Bamboo oil (CBO). The chromaticities of light, red, and yellow in RBO were 92.4 and 3.0, respectively. This result indicates that the chromaticity of light was increased with the decrease in the tar concentration in the Bamboo oil. The total concentrations of organic acid and phenolics compound in RBO were decreased to about 63% and 80%, respectively. The total concentration of free sugars was decreased to about 78% in RBO and the concentration of free sugar was in the order of lactose, fructose, and glucose. The palmitoleic acid and stearic acid concen- trations were higher than that of other fatty acids. The concentration of total organic acid was decreased to about 88% through RBO. Among the various organic acids, the formic acid concentration was highest in the RBO. The minerals con- centrations in the CBO were in the order of Ca, K, Na, and Fe. On the other hand, in the case of RBO, it was in the order of Ca, Fe, K, and Na.
