YANEZ-RUEDA, Xiomara et al. Chemical composition and biological activity of essential oils Calycolpus moritzianus collected in the Norte de Santander, Colombia. Rev. Univ. Ind. Santander. Salud [online]. 2009, vol.41, n.3, pp.259-267. ISSN 0121-0807.

Background: Essential oils of plants of the family Myrtaceae have been evaluated for different biological activities. The aim of this research was the chemical characterization and evaluation of antifungal, antiviral and cytotoxic activity of 40 essential oils extracted from Calycolpus moritzianus, commonly called "arrayán" or "cínaro", collected in several areas of Norte de Santander, Colombia. Materials and methods: antifungal activity was determined following the protocols AFST-EUCAST for Candida krusei and C. parasilopsis, and CLSI-M38A for Aspergillus fumigatus and A. flavus. Cytotoxicity was evaluated on tumoral (HeLa and Jurkat), and non tumoral (Vero) cell lines by the MTT photo-colorimetric technique The in vitro antiviral activity against Herpes simplex virus HSV-1 was determined by the end-point titration technique (EPTT). Results and Discussion: X38 and X39 oils of plants collected in regions of Chinácota and Salazar regions showed activity against C. krusei with minimal inhibitory concentration values of 500 μg/mL. None of the oils was cytotoxic in no-tumor (Vero) cells . Oils X9 and X10 of plants from regions of Salazar and Pamplonita were the most cytotoxic on HeLa cells at concentrations of 37.8 ± 2.4 and 40.6 ± 2.6 μg/mL, respectively. The reduction of viral load in cell cultures only was showed by X11 oil. Antifungal and antitumor activity of these oils was correlated with the composition of the major components showing activity for Terpinen-4-ol, (-) Limonene, Linalool and a-Pinene.
