Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
SKBR3 cells 1 μM Citral significantly reduced ALDH2-dependent Aldefluor fluorescence, indicating its inhibitory effect on ALDH2. Mol Oncol. 2016 Nov;10(9):1485-1496
MDA-MB-468 cells 100 μM 24 h Citral significantly reduced ALDH1A3-dependent Aldefluor fluorescence, indicating effective inhibition of ALDH1A3 activity. Mol Oncol. 2016 Nov;10(9):1485-1496
MDA-MB-231 cells 100 μM 24 h To evaluate the apoptotic effect of citral on ALDH1A3-overexpressing cells, results showed that 100 μM citral induced low-level cell death after 24 h. Mol Oncol. 2016 Nov;10(9):1485-1496
Phytophthora capsici 22.9 μg/mL 3 days To evaluate the effect of citral on the mycelial growth and morphology of Phytophthora capsici. Results showed that 22.9 μg/mL citral significantly affected mycelial growth and morphology. Mol Plant Pathol. 2023 Aug;24(8):932-946
Phytophthora capsici 1.4 μg/mL 3 days To evaluate the effect of citral on the mycelial growth of Phytophthora capsici. Results showed that 1.4 μg/mL citral had little effect on mycelial growth. Mol Plant Pathol. 2023 Aug;24(8):932-946
Salmonella Typhimurium 0.2 mg/mL and 0.3 mg/mL 2, 4, 6, 8 min Evaluate the antibacterial effect of CLNE on Salmonella Typhimurium. Results showed that 0.3 mg/mL CLNE treatment for 8 min reduced bacterial counts by 0.57 log CFU/mL. Ultrason Sonochem. 2023 Jan;92:106269

Administration Dosage Frequency Description References
Female ApoE−/− mice Atherosclerosis model induced by GAN diet with 1.3% L-carnitine Oral gavage 20 mg/kg Once daily for 16 weeks Citral ameliorated atherosclerosis by modulating gut microbiota and suppressing TMAO formation, improved plasma lipid profile, reduced aortic plaque formation, decreased plasma inflammatory cytokine levels, and improved insulin resistance NPJ Sci Food. 2023 May 20;7(1):19
NOD/SCID mice Breast cancer xenograft model Tail vein injection 0.4 mg/kg Every 3 or 4 days for 38 days Nanoparticle-encapsulated citral significantly reduced tumor volume and weight in ALDH1A3-overexpressing MDA-MB-231 cells but had no significant effect on control cells. Mol Oncol. 2016 Nov;10(9):1485-1496
Nicotiana benthamiana Phytophthora capsici infection model Fumigation 1.4 μg/mL Single treatment, lasting 36 hours To evaluate the inhibitory effect of citral on Phytophthora capsici infection in vivo. Results showed that 1.4 μg/mL citral significantly limited the development of lesions and reduced the relative pathogen biomass. Mol Plant Pathol. 2023 Aug;24(8):932-946
Male Swiss mice Obese mouse model fed with standard diet (SD) or high-fat diet (HFD) for 12 weeks Oral (gavage) 25, 100, and 300 mg/kg Single dose, observed for 360 minutes To investigate the effect of citral on body temperature (Tb) and inflammatory signaling during LPS-induced systemic inflammation (SI). Citral (300 mg/kg) significantly reduced Tb variation in HFD-fed animals, decreased peripheral levels of tumor necrosis factor (TNF)-α in both SD and HFD mice, and reduced serum leptin concentration in HFD mice 90 min after LPS challenge. Additionally, citral also reduced interleukin (IL)-6 levels in the hypothalamus of obese mice. Biomolecules. 2020 Oct 17;10(10):1454

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
Protocol 1
Protocol 2
The prepared working fluid is recommended to be prepared now and used up as soon as possible in a short period of time. The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
