Ippia Alba Essential Oil: A Promising Complementary Therapy for Breast Cancer.

Breast cancer remains a pressing global health issue, spurring exploration into innovative therapies. This review focuses on Lippia alba (Mill.) essential oil's potential as a complementary breast cancer treatment. With growing interest in natural approaches, Lippia alba shows promise in breast cancer management. The review will explore Lippia alba's multifaceted role in treatment, highlighting its anticancer effects on breast cancer cells, potential synergy with conventional treatments, safety profiles, and existing clinical evidence. It will also address knowledge gaps, stressing the need for further research to unlock Lippia alba's full therapeutic potential in breast cancer therapy. In a field craving novel therapies, this review offers a timely analysis. Despite the lack of existing reviews on this topic, Lippia alba's significance cannot be understated. As research progresses, this article will be a valuable resource for researchers and healthcare practitioners seeking to augment breast cancer management through complementary therapies.

Towards gas chromatography-mass spectrometry coupling protocols for both identifying and quantification essential oils of Thymus capitatus Hoff et Link.

Essential oil of Thymus capitatus Hoff et Link is analysed by using four techniques: GC/pyrolyse/MS, GC/FID, electronic impact GC/MS (quadripole), and GC/MS (ion trap). Both major and trace components are analysed. The GC/pyrolyse/MS coupling provides reference to the exact mass compositions without any need of the previously purified references, neither for major or trace components. The comparison between this reference analysis and GC/FID shows that the FID response coefficients may vary by a mean 7% from one component to another. As it was expected, quadripole or ion trap response coefficients vary to a much greater extent (a mean 25%), although the two MS techniques response coefficients are first order consistent. We conclude that GC/MS coupling could be used not only as it is usual for reliable identifications, but also for a complete quantitative routine analysis of essential oils. Expected precision could be very similar to GC/FID precision provided correcting species by species the MS analysis by a mean value of the response coefficient measured for the MS 70 eV electronic impact ionisation technologies. The GC/pyrolyse/MS coupling is proposed as a relevant tool for analysing reference samples containing trace natural species that could not be purified.
