Application


  • Exploring the binding affinity and characteristics of DcitOBP9 in citrus psyllids.: This study delves into the interactions between DcitOBP9, a key odorant-binding protein, and citral in citrus psyllids, providing insights into pest behavior and potential targets for eco-friendly pest management strategies (Pei et al., 2024).

  • Synergistic anti-virulence efficacy of citral and carvacrol against mixed vaginitis causing Candida albicans and Gardnerella vaginalis: An in vitro and in vivo study.: Demonstrates the combined use of citral and carvacrol as a potent anti-virulence strategy against pathogens in mixed vaginitis, showcasing a promising lead for non-antibiotic treatments (Jothi and Gowrishankar, 2024).

  • Effect of polyethoxylated flavonoids (PMFs)-loaded citral and chitosan composite coatings on citrus preservation: From the perspective of fruit resistance.: Discusses innovative food preservation techniques using citral-infused coatings to enhance the storage life and quality of citrus fruits, addressing critical issues in food technology (Li et al., 2024).

  • Synthesis, antifungal activity and action mechanism of novel citral amide derivatives against Rhizoctonia solani.: Explores the synthesis of citral derivatives for use as antifungal agents, offering new solutions for controlling fungal diseases in crops with potential applications in sustainable agriculture (Zhang et al., 2024).
