| Summary: | As an excellent variety of <i>Camphora glanduliferum</i>, Honganzhang has high essential oil content and can be used as industrial and pharmaceutical raw materials to extract essential oil, which has high development value. In this study, fresh branches and leaves of <i>C. glanduliferum</i> ’Honganzhang’ were used as materials. After extracting <i>C. glanduliferum</i> ’Honganzhang’ essential oils (CGHEO) by steam distillation, gas chromatography-mass spectrometry (GC-MS) was used to analyze its chemical components. On this basis, the antibacterial effect of CGHEO and its potential physiological mechanism were further explored. The results showed that the main components of CGHEO were Cineole (46.57%), α-terpineol (9.93%), Sabinene (8.02%), β-terpinene (6.04%), and α-pinene (4.49%), these compounds can be used in medicine, food and other industries. In terms of antibacterial effect, CGHEO has significant antibacterial effects on three Gram-negative bacteria (<i>Escherichia coli</i>, <i>Salmonella enteritidis</i>, and <i>Pseudomonas aeruginosa</i>), and two Gram-positive bacteria (<i>Bacillus subtilis</i> and <i>Staphylococcus aureus</i>). CGHEO can reduce Na<sup>+</sup>K<sup>+</sup>-ATPase activity and SDH activity and further interfere with the operation of the bacterial respiratory chain, thereby achieving the effect of inhibiting bacterial reproduction. Based on the main chemical components contained in <i>C. glanduliferum</i> ’Honganzhang’ and its remarkable antibacterial effect, this study is expected to provide a theoretical basis for the wide application of <i>C. glanduliferum</i> ’Honganzhang’ in multiple fields such as medicine, health care, food, and industry. |
