“…Of which, S. tonkinense essential oil had greater amounts of sesquiterpenes than S. attopeuense essential oil. These results are consistent with previous studies, which found greater amounts of sesquiterpene compounds in essential oils of Syzygium species (Rameshkumar et al, 2015;Sarvesan et al, 2015;Huong et al, 2017;Khanh and Ban, 2020). Furthermore, the high content of (E)-caryophyllene in the essential oils of the two studied Syzygium species is noteworthy, especially S. tonkinense.…”

“…Furthermore, the high content of (E)-caryophyllene in the essential oils of the two studied Syzygium species is noteworthy, especially S. tonkinense. It was also noted previously that the volatile constituents of most Syzygium species reported from Vietnam contained high amounts of (E)-caryophyllene (Huong et al, 2017;Khanh and Ban, 2020;Tran et al, 2021;Huong et al, 2022). However, several other species of Syzygium with either a low content or total absence of (E)-caryophyllene have been reported from other countries (Chalannavar et al, in previous studies (Bassolé et al, 2003;Senthilkumar and Venkatesalu, 2010;Chau et al, 2020).…”

The present study is the first to investigate the chemical composition, antimicrobial and larvicidal activities of the essential oils from the leaves of Syzygium attopeuense (Gagnep.) Merr. & L.M.Perry and Syzygium tonkinense (Gagnep.) Merr. & L.M.Perry collected in Vietnam. The essential oils were extracted by hydrodistillation and analyzed by GC and GC–MS. The study indicated the presence of a high percentage of sesquiterpenes in both investigated essential oils. The major components of S. attopeuense essential oil were bicyclogermacrene (24.26%), (E)-caryophyllene (11.72%), and (E)-β-ocimene (6.75%), whereas S. tonkinense essential oil was dominated by (E)-caryophyllene (80.80%). The antimicrobial activity of essential oils was evaluated by broth microdilution assay to determine the minimum inhibitory concentration (MIC) and median inhibitory concentration (IC50). Both essential oils exhibited remarkable inhibitory activity against all tested Gram-positive bacteria and yeast than Gram-negative bacteria. Among them, essential oils of S. attopeuense and S. tonkinense possessed the strongest activity against Enterococcus faecalis (MIC = 4.00 μg/mL; IC50 = 1.69 μg/mL) and Candida albicans (MIC = 16.00 μg/mL; IC50 = 8.67 μg/mL), respectively. Furthermore, the larvicidal activity of essential oils was tested using fourth-instar larvae of Aedes aegypti. Results from the larvicidal test revealed that both essential oils had an excellent inhibitory effect against A. aegypti larvae with LC50 values from 25.55 to 30.18 μg/mL and LC90 values from 33.00 to 39.01 μg/mL. Our findings demonstrate that the essential oil extracted from S. attopeuense and S. tonkinense are potential sources of natural antimicrobials and can act as inexpensive mosquito larvicidal agents.

“…Sesquiterpenes were the major class of compounds. Among them, major compounds identified are β‐caryophyllene; α‐pinene; α‐selinene; and α‐humulene (Khanh & Ban, 2020 ). S. lanceolatum leaves yielded essential oil upon hydrodistillation, and 18 compounds in one study and 106 compounds in another study were identified through GC‐MS analysis.…”

This comprises medicinal plants not only important for the treatment of diseases but also as potential material for maintaining good health and conditions. Better cultural acceptability, better compatibility and adaptability with the human body, and lesser side effects of plants made many countries in the world to depend on herbal medicine for their primary health care (Bari et al., 2021;CHOWDHURY et al., 2021;Hoque et al., 2021). For centuries, plants are being widely used for their natural resources isolated from various parts of a plant and have been used in the treatment of human diseases. Moreover, some of these plants produce edible fruits, while others simply produce dazzling flowers, which are so attractive and important economically as well.The knowledge of traditional medicine supports all other systems of medicine such as Ayurveda, Siddha, Unani, and even modern

“…As mentioned above, Vietnamese S. hancei, S. lineatum , and S. sterrophyllum were dominated by β ‐caryophyllene. [ 4,5 ] Meanwhile, bicyclogermacrene (21.23%), and β ‐caryophyllene (23.40%) were also characteristics of another Vietnamese Syzygium , S. tsoongii . [ 13 ] The current result indicated a close relationship among these plants, as well as the role of geographic factor.…”

“…For instance, β ‐caryophyllene (> 40.0%) can be seen as the principal compound in the leaf oils of S. hancei and S. lineatum , collected from Hatinh. [ 4 ] This compound (25.6‐29.3%) was also characteristic of the essential oils of S. sterrophyllum leaf and stem, gathered from Nghe An. [ 5 ]…”

Essential oil obtained from hydrodistillation of the Vietnamese Syzygium boisanum leaves was analyzed by the GC/FID‐MS (gas chromatography/flame ionization detection‐mass spectrometry). Forty‐five compounds (90.08%) were namely identified, in which sesquiterpene hydrocarbons (73.07%) were the major chemical class. Among identified compounds, β‐caryophyllene (18.21%) and bicyclogermacrene (25.47%) were the principal compounds. This essential oil was comparable with the positive control streptomycin in an antimicrobial assay against three Gram‐positive bacteria Enterococcus faecalis ATCC299212, Staphylococcus aureus ATCC25923, and Bacillus cereus ATCC14579. Docking study of two major sesquiterpene hydrocarbons β‐caryophyllene and bicyclogermacrene against bacterial DNA gyrase B showed that these two compounds mainly interacted with hydrophobic residues at the rim of the pocket, thereby they are possible inhibitors.
