“…The leaf essential oil of S. nervosum was rich in (Z)-β-ocimene (20.3%), caryophyllene oxide (13.2%), (E)-caryophyllene (12.1%), and α-pinene (5.2%) ( Table 4). The leaf essential oil composition is qualitatively similar, but quantitatively different, to a previous report on the leaf essential oil from Lê Mao District, Vinh City, Vietnam [51]. Both samples had relatively high concentrations of α-pinene, (Z)-β-ocimene, (E)-β-ocimene, and (E)-caryophyllene (3.7%, 32.1%, 9.4%, and 14.5%, respectively, in the Vinh City sample), but the concentration of myrcene was much higher (24.6%) in the sample from Vinh City.…”

Mosquitoes are important vectors of several diseases, and control of these insects is imperative for human health. Insecticides have proven useful in controlling mosquito populations, but insecticide resistance and environmental concerns are increasing. Additionally, emerging and re-emerging microbial infections are problematic. Essential oils have been shown to be promising mosquito larvicidal agents as well as antimicrobial agents. In this work, the essential oils from four species of Myrtaceae (Baeckea frutescens, Callistemon citrinus, Melaleuca leucadendra, and Syzygium nervosum) growing wild in central Vietnam have been obtained by hydrodistillation and analyzed by gas chromatographic techniques. The essential oils have been screened for mosquito larvicidal activity against Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus, and for antimicrobial activity against Enterococcus faecalis, Staphylococcus aureus, and Candida albicans. Callistemon citrinus fruit essential oil, rich in α-pinene (35.1%), 1,8-cineole (32.4%), limonene (8.2%), and α-terpineol (5.8%) showed good larvicidal activity with 24-h LC 50 = 17.3 µg/mL against both Ae. aegypti and Cx. quinquefasciatus, and good antibacterial activity against E. faecalis (minimum inhibitory concentration (MIC) = 16 µg/mL) The 48-h larvicidal activities of M. leucadendra leaf essential oil, rich in α-eudesmol (17.6%), guaiol (10.9%), linalool (5.1%), (E)-caryophyllene (7.0%), and bulnesol (3.6%) were particularly notable, with LC 50 of 1.4 and 1.8 µg/mL on Ae. aegypti and Cx. quinquefasciatus. Similarly, M. leucadendra bark essential oil, with α-eudesmol (24.1%) and guaiol (11.3%), showed good antibacterial activity against. E. faecalis. Both B. frutescens and C. citrinus leaf essential oils demonstrated anti-Candida activities with MIC values of 16 µg/mL. The results of this investigation suggest that essential oils derived from the Myrtaceae may serve as "green" alternatives for the control of mosquitoes and/or complementary antimicrobial agents.

“…Previously, we have reported the chemical composition and antibacterial properties [11] of the essential oil and various organic extracts of C. operculatus buds against food-borne pathogens and multiantibiotic-resistant bacteria as well as the antiinflammatory property of its oil [12]. The GC/MS analysis of the leaf essential oil of C. operculatus has also been reported [13]. In the present study, a detailed in-vitro and in-vivo investigation was conducted to test the efficacy of essential oil and various organic extracts of C. operculatus buds against plant pathogenic bacteria of Xanthomonas spp.…”

This study was undertaken to assess the antibacterial efficacy of the essential oil and extracts of Cleistocalyx operculatus buds against plant pathogenic bacteria of Xanthomonas spp. The diameter of inhibition zones of oil (1,000 lg/disc) and extracts (1,500 lg/disc) against the tested bacteria were found in the range of 7-23 mm. The MIC and MBC values of the oil and extracts against the tested Xanthomonas spp. ranged from 31.25-125 to 62.5-250 lg/ml and 125-500 and 250-1,000 lg/ml, respectively. The cell viability study demonstrated a potential detrimental effect of the oil (1,000 lg/ml) and hexane extract (250 lg/ml) on the tested Xanthomonas spp. Also the oil displayed significant antibacterial effects in vivo against Xoo KX019 and Xsp SK12 conducted on greenhouse-grown oriental melon plants (Cucumis melo L. var. makuwa). The results of this study suggest that C. operculatus-derived essential oil and extracts could be used as natural bactericides in the food and agriculture industries.

“…Furthermore, the other beneficial effects of C. operculatus such as anticancer, antihyperglycemic hypolipidemic, and cardiotonic effects are well documented [ 16 , 17 ]. In addition, Dũng et al (1994) have analyzed the chemical composition of essential oil isolated from Cleistocalyx operculatus leaves [ 18 ]. Recently, Dosoky et al (2015) proved that essential oil of Cleistocalyx operculatus leaves possessed a strong antimicrobial effect and cytotoxicity to cancer cell lines [ 19 ].…”

Several herbal remedies have been used as topical agents to cure burn wound, one of the most common injuries in worldwide. In this study, we investigated the potential use of Cleistocalyx operculatus essential oil to treat the burn wound. We identified a total of 13 bioactive compounds of essential oil, several of which exhibited the anti-inflammatory and antimicrobial activities. Furthermore, the essential oil showed the antibacterial effect against S. aureus but not with P. aeruginosa. The supportive effect of essential oil on burn wound healing process also has been proven. Among three groups of mice, wound contraction rate of essential oil treated group (100%) was significantly higher than tamanu oil treated (79%) and control mice (71%) after 20 days (0.22 ± 0.03 versus 0.31 ± 0.02 cm2, resp., p < 0.05). Histological studies revealed that burn wounds treated with essential oil formed a complete epidermal structure, thick and neatly arranged fibers, and scattered immune cells in burn wound. On the contrary, saline treated burn wound formed uneven epidermal layer with necrotic ulcer, infiltration of immune cells, and existence of granulation tissue. This finding demonstrated Cleistocalyx operculatus essential oil as promising topical dermatological agent to treat burn wound.
