Matebie, Wondwosen Abebe published the artcileChemical composition and antimicrobial activity of essential oil from Phytolacca dodecandra collected in Ethiopia, Recommanded Product: Benzyl acetate, the main research area is Phytolacca essential oil aroma antimicrobial; HS-SPME; Phytolacca dodecandra; antimicrobial activity; chemical composition; essential oil.
The essential oil from Phytolacca dodecandra, a traditional herb of Ethiopia, has been studied, including the chem. composition and antimicrobial activity. The difference between four P. dodecandra samples (P-1-P-4), which differed in gender or location, has also been analyzed. The essential oils were obtained by steam distillation, while the aromas were extracted by head space solid-phase microextraction (HS-SPME) and both were analyzed by gas chromatographymass spectrometry (GC-MS). The oils’ antimicrobial activities were evaluated by the microdilution method against Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Candida albicans. Ninety one components, representing 88.37 to 94.01% of the aromas, were identified. The compositions of the aromas of four samples are mainly dominated by aldehydes and ketones: 2-nonanone (1.80-30.80%), benzaldehyde (4.99-25.99%), and sulcatone (2.34-5.87%). Sixty components representing 64.61 to 69.64% of the oils were identified, and phytone (3.04-21.23%), phytol (4.11-26.29%) and palmitic acid (1.49-23.87%) are the major compounds No obvious antimicrobial activity was observed for all the four essential oils.
Molecules published new progress about Aldehydes Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 140-11-4 belongs to class esters-buliding-blocks, name is Benzyl acetate, and the molecular formula is C9H10O2, Recommanded Product: Benzyl acetate.
