Extraction Technology of the Essential Oil from Chestnut Flower and Its Antibacterial Activity
The essential oil of Chestnut flower has many biological functions such as insecticidal activity and antibacterial proterties, and it can be used as a natural preservative and repellents. In this article, the optimum extraction technology of the essential oil from Chestnut flower extracted by steam distillation and its antibacterial activity were studied by the methods of single-factor and orthogonal experiment. The results showed that the optimum extraction technology was when 1 cm segment of flowers in 40 g/L sodium chloride at the ratio of material to solvent 1∶10 (g/mL), distilling 3 h, the highest essential oil was gotten with (0.621 ±0.008)%. And the antibacterial activity of essential oil against E. coli, Bacillus subtilis and Saccharomyces cerevisiae was also investigated by the method of inhibition zone. The results displayed that the essential oil has antibacterial activity , and the order of inhibitory effects was Saccharomyces cerevisiae > Bacillus subtilis > E.coli. This study can provide technical support for the utilization and development of Chestnut flower.
