“…In addition, the rhizome and fruit essential oil manifested antibacterial action against P. aerugi nosa and S. aureus, respectively, with MIC values of 400 μg/mL. The observed antibacterial result of A. longiligulare essential oils was in agreement with previous information that Amo mum essential oils selectively inhibited the growth of different microorganisms (Huong et al, 2020;Huong et al, 2021).…”

“…The bacterial growth inhibition of the essential oils was evaluated using two strains of Gram-positive test bacteria, Staphylococcus aureus (ATCC25923) and Bacillus cereus (ATCC14579), plus two strains of Gram-negative test bacteria, Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC27853). Minimum inhibitory concentration (MIC) values were measured by the broth microdilution assay as previously described (Huong et al, 2020;Huong et al, 2021). Stock solutions of each of the essential oils were prepared using dimethylsulfoxide.…”

This paper reports the chemical constituents and the antibacterial activity of essential oils from the leaves, rhizomes, and fruits of Amomum longiligulare T.L. Wu (Zingiberaceae) obtained by microwave-assisted hydrodistillation. The essential oils were analyzed by gas chromatography–mass spectrometry techniques. The minimum inhibitory concentration (MIC) values were measured by the broth microdilution assay. The oil yields of leaves, rhizomes and fruits from A. longiligulare were 0.23%, 0.27% and 1.93% (v/w), respectively, calculated on a dry weight basis. The leaf essential oil comprised mainly α-humulene (28.4%), α-pinene (24.9%), β-caryophyllene (17.3%), humulene epoxide II (7.3%), and β-pinene (4.7%). The major compounds of the rhizome essential oil were β-caryophyllene (28.7%), bicyclogermacrene (17.1%), humulene epoxide II (10.5%), camphene (7.9%), and α-pinene (5.7%). Camphor (40.7%) and bornyl acetate (34.2%) were the main constituents of the fruit oil. The essential oils demonstrated antimicrobial activities against Staphylococcus aureus, Bacillus cereus, Escherichia coli, and Pseudomonas aeruginosa with the MIC values ranging from 200 to 400 μg/mL. In summary, the A. longiligulare essential oils are a source of promising antibacterial agents. This is the first report on the chemical composition and antibacterial activity of A. longiligulare essential oil obtained by microwave-assisted hydrodistillation.

“…This result also matches well with previous studies. As mentioned above, β -pinene accounted for 35.8% of the leaf oil of A cinnamomeum , 8 from 20% to 31.8% of the leaf oils of 2 other Vietnamese species, H stenopetalum and H coronarium , 9 and 33.5% of the leaf oil of A tonkinensis . 10 β -Pinene was also recorded in high amounts of 85.8%-71.3% in the rhizome oil of A purpurata and 31.4% in the leaf oil of H coronarium , collected from Fiji.…”

“…The seed oil of Amomum tsao-ko , collected from Laocai-Vietnam, was dominated by 1,8-cineole (30.6%), 2-decenal (17.3%), and geranial (10.6%), 7 whereas the antimicrobial activity of the leaf oil of another Vietnamese Amomum , Amomum cinnamomeum , was primarily dependent on the role of the main constituents β -pinene (35.8%), ( E )-cinnamaldehyde (11.5%), and caryophyllene oxide (5.9%). 8 β -Pinene (20%-31.8%) was among the major compounds present in the leaf oils of Hedychium stenopetalum, and Hedychium coronarium , gathered from Sonla, Vietnam. 9 Similarly, β -pinene (12.1%-33.5%) was the principal compound in the leaf oils of another 2 Vietnamese species, Alpinia globosa and Alpinia tonkinensis .…”

Essential oils of the leaves of 4 Vietnamese Zingiberaceae species were first obtained by hydro-distilled, and their chemical compositions were identified by gas chromatography-flame ionization detection/mass spectrometry . β-Pinene (21.7%), sabinene (12.8%), and α-pinene (8.0%) were the main compounds in Wurfbainia tenella leaf oil. The essential oil of Hedydium villosum var. tenuifolium leaf was dominated by β-pinene (23.7%), β-caryophyllene (21.6%), and 1,8-cineole (14.0%). β-Pinene (27.4%), α-pinene (21.2%), limonene (12.1%), and myrcene (8.6%) were the characteristic components of Meistera sudae leaf oil, and β-pinene (32.8%) and ( E)-methyl cinnamate (15.8%) of Alpinia hongiaoensis leaf oil. The 4 oil samples exhibited antimicrobial activity against Bacillus subtilis (American Type Culture Collection [ATCC] 27212), Staphylococcus aureus (ATCC 12222), Escherichia coli (ATCC 8739), Pseudomonas aeruginosa (ATCC 25923), Aspergillus niger (ATCC 9763), Fusarium oxysporum (ATCC 48112), Candida albicans (ATCC 10231), and Saccharomyces cerevisiae (ATCC 2601) at different levels. Especially, the leaf oil of M sudae showed strong activity against B subtilis, S aureus, and S cerevisiae with a minimum inhibitory concentration (MIC) value of 25.0 µg/mL.
