The essential oils of three specimens of (A, B and C) and were extracted by hydrodistillation, and the chemical compositions from the essential oils were identified by gas chromatography and flame ionization detection (CG/MS and CG-FID). The fungicide potential of the EOs against five fungicide yeasts was assessed: INCQS-40175, ATCC 6258, ATCC 62894, ATCC 13803 and IEC-01. The essential oil of the specimen (A) was characterized by the major compounds: α-bulnesene (26.79%), pogostol (21.27%) and δ-amorphene (6.76%). The essential oil of the specimen (B) was rich in ( )-nerolidol (44.4%), (E)-γ-bisabolene (10.64%) and ( , )-α-farnesene (8.19%), while ( )-nerolidol (92.21%) was the majority of the specimen (C). The sesquiterpenes seline-3,11-dien-6-α-ol (12.93%), eremoligenol (11%) and γ-elemene (10.70%) characterized the chemical profile of the EOs of . The fungal species were sensitive to the essential oil of (B) (9-11 mm), and the lowest inhibitory concentration (0.07%) was observed in the essential oil of (A) against the yeasts of . Fungicidal action was observed in the essential oils of (A) against , with an MIC of 0.78 µL/mL and 3.12 µL/mL; , with an MFC of 50 µL/mL and (C) against ; and , with a MFC of 50 µL/mL.
