This study describes the chemical analysis and antimicrobial assay of two Zingiber species Zingiber eberhardtii and Z. skornickovae. The rhizome oils were analyzed using GC-MS, and the results showed that both oils exhibited antimicrobial activity against Gram (+) bacteria and yeast.
Zingiber is a genus of medicinal plants containing a rich resource of essential oils. The current study aims to describe chemical analysis and antimicrobial assay for two Zingiber species Zingiber eberhardtii Gagnep. and Z. skornickovae N.S. LATIN SMALL LETTER Y WITH ACUTE. The rhizome oils, which were obtained by hydro-distillation using a Clevenger apparatus, were analyzed by GC-MS (gas chromatography-mass spectrometry). Extraction of Z. eberhardtii rhizome gave a yellow oil with 41 identified compounds (96.3%), in which linalool (34.9%) and 1,8-cineole (12.7%) were the principal compounds. The yellow oil of Z. skornickovae rhizome included 53 identified compounds (97.8%), with & beta;-pinene (25.0%), (E)-caryophyllene (8.8%), and & alpha;-pinene (7.9%) as the major agents. By broth dilution method, both oils moderately controlled the growth of Gram (+) bacteria Bacillus subtilis ATCC 6633 and Staphylococcus aureus ATCC 25923 with the same MIC (minimum inhibitory concentration) value of 128 & mu;g/mL. In particular, Z. skornickovae rhizome oil showed the best antimicrobial activity against yeast Saccharomyces cerevisiae ATCC 4098 with a MIC value of 64 & mu;g/mL. The obtained results are promising information for future research.
