Article Synopsis
- Bacterial resistance is a growing global issue, leading to difficulties in treating infectious diseases, prompting the exploration of natural products like plant secondary metabolites to help address the problem.
- Two fruit essential oils were extracted using hydrodistillation and analyzed, revealing significant antibacterial and antifungal properties along with a detailed breakdown of their chemical composition.
- The essential oils showed strong antibacterial effects against specific bacteria at low concentrations, while demonstrating limited antifungal activity, and no significant toxicity to human cancer cells was found, highlighting their potential as alternative antimicrobial agents.
Unlabelled: (turmeric) has been used in Chinese traditional medicine and Ayurvedic medicine for many years.
Methods: The leaf essential oil of from southern Nigeria was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The essential oil was screened for antibacterial, antifungal, and cytotoxic activities.
The crude bark extract of Zanthoxylum setulosum from Monteverde, Costa Rica was notably cytotoxic (100% kill at 100 microg/mL) to MCF-7, MDA-MB-231, and MDA-MB-468 cells in vitro. Phytochemical studies of the bark extract revealed the triterpenoid lupeol, the lignan sesamin, the sesquiterpene sesquichamaenol, and the xanthone lichexanthone. This is the first report of the isolation of sesquichamaenol and lichexanthone from the bark extract of Z.
