Abstract:
In this study, the chemical composition, antioxidant and antimicrobial activities of the essential oil from Cleome gynandra L. seeds were investigated. The essential oil was extracted by hydrodistillation, and gas chromatography–mass spectrometry (GC-MS) was employed to analyze the chemical composition of the essential oil. Based on a comparison with the NIST 05 mass spectral library, 61 compounds were identified, and the main components were trans-9-octadecenoic acid (17.14%), n-hexadecanoic acid (9.91%), n-decanoic acid (8.62%), 1,13-tetradecadiene (7.89%), linoleic acid (5.32%), and heptanoic acid (4.21%). The essential oil from Cleome gynandra L. seeds had a good 2,2-diphenyl-1-picryhydrazyl (DPPH?) radical scavenging capacity. The antimicrobial activity of the oil was tested by the zone of inhibition test method. The essential oil showed very strong antimicrobial activity against Bacillus Megaterium, Bacillus subtilis, and Staphylococcus aureus, as well as a relatively strong antimicrobial activity against Escherichia coli. The study indicated that the essential oil from Cleome gynandra L. seeds had certain antioxidant and antimicrobial effects, which may be attributed to the chemical composition.
