化橘红成花过程挥发油成分的动态变化及活性分析
Dynamic change and activity analysis of volatile oil in the flowers of Citri Grandis Exocarpium
摘要
Abstract
The aims of the study was to evaluate dynamic change of volatile oil in the flowers of Citri Grandis Exocarpium(CGE),and to provide data for application of CGE flower and development of its volatile oil.Prior to ingredient evaluation of the volatile oil by gas chromatography-mass spectrometry(GC-MS),distillation extraction was conducted on freshly-picked flowers of CGE at four flower development stages(bud initiation,pre-bloom,full-bloom and withered flower).Activity analysis of volatile oil was then carried out based on network for flower of CGE-activity components-targets.Results showed that volatile oil of CGE flower mainly involve γ-terpinene,D-limonene,linalool,farnesol,nerolidol,β-pinene,alkenes(56.84%～70.19%)and alcohols(21.33%～38.34%).The alkenes displayed a gradual declination at flower development stages,and the alcohols showed a tendency to increase and then decrease,peaking at full-bloom.The total amount of volatile components kept a high level at bud initiation,pre-bloom,full-bloom stages,and individually decreased at withered flower stages.Farnesol,linalool,α-phellandrene,nerolidol and citronellol,of all the volatile components,has a higher activity in antibacterial and oxidation-resistant properties.关键词
