Objective: To investigate the expression of bcl-2 and bax genes in the liver cancer cell line HepG2 after apoptosis induced by essential oils from Rosmarinus officinalis.
Methods: Essential oils from Rosmarinus officinalis were collected by steam distillation, then its chemical composition was determined by GC-MS. Expression of bcl-2 and bax genes were detected by immunohistochemical method.
Results: The liver cancer cell line HepG2 was treated with essential oils from Rosmarinus officinalis at various concentrations for different duration. Expression of bcl-2 gene reduced and expression of bax gene increased in a dose and time dependent manner.
Conclusion: Essential oils from Rosmarinus officinalis can affect the pattern of bcl-2 and bax genes expressions, and this may increase the apoptosis of liver cancer cell line HepG2.

Bacterial resistance, a global public health concern prioritized by the World Health Organization, is particularly alarming in Staphylococcus aureus and Escherichia coli. Urgently addressing this, the search for new antibiotics has turned to plant essential oils. Our study focused essential oils derived from Colombian plants Croton killipianus, Croton smithianus, Croton leptostachyus, Croton hondensis, and Croton gossypiifolius.

Monoterpenes (MTs), the major constituents of plant essential oils, cover a broad spectrum of biological activities through their interaction with biomembranes. MTs are highly hydrophobic substances with a net electrical dipole, but are not clearly amphipathic. As a result, they aggregate at increasing concentrations in aqueous media, and in membrane environments their behavior changes from dynamics modulators to disruptors.

Volatile compounds have a deep influence on the quality and application of the medicinal herb ; however, little is known about the effect of UV-B radiation on volatile metabolites. We herein investigated the effects of UV-B exposure on the volatile compounds and transcriptome of to assess the potential for improving its quality and medicinal characteristics. Out of 733 volatiles obtained, a total of 133 differentially expressed metabolites (DEMs) were identified by metabolome analysis.

: Essential oils (EOs) have been exploited by humans for centuries, but many sources remain poorly investigated, mainly due to the low yields associated with conventional extraction. Recently, new techniques have been developed, like solvent-free microwave extraction (SFME), able to enhance efficiency and sustainability. The use of L.
