九宫香菊挥发油的抑菌活性

该试验旨在研究九宫香菊挥发油的抑菌活性并分析其主要成分。以大肠杆菌和金黄色葡萄球菌作为供试菌种,研究菊花提取物的抑菌活性。采用水蒸气蒸馏法提取挥发油,通过气相色谱-质谱法分析挥发油的主要成分。结果表明:九宫香菊的花序和鲜茎叶挥发油对金黄色葡萄球菌、大肠杆菌均有明显的抑菌作用。茎叶挥发油所含主要成分与花序较为相似,但茎叶中1-石竹烯含量相对更高,而无桧烯等成分。九宫香菊茎叶与花序的挥发油组成相似,花序与鲜茎叶均具有一定的抑菌活性。该试验为菊花鲜茎叶的开发提供参考。

Antibacterial Activity of Volatile Oil from Jiugong Xiangju

It is to study the antibacterial activity of volatile oil from Jiugong Xiangju and analyze its main components.Escherichia coli and Staphylococcus aureus are used to detect the antibacterial activity of extract from Xiangju.The volatile oil is extracted by steam distillation,and analyzed by GC-MS.The results show that the volatile oil from flos and fresh stem and leaf has obvious antibacterial effects on Staphylococcus aureus and Escherichia coli.The main components of volatile oil from chrysanthemum flos,and stem and leaf are similar,but the content of 1-caryophyllene is relatively higher,with no component such as pinene.The constituents of chrysanthemum flos,and stem and leaf are quite similar,and flos,fresh stem and leaf have some antibacterial activity.This research provides a basis for the development of fresh chrysanthemum stem and leaf.
