“…The acetone extract of R. tomentosa leaves significantly inhibited the generation of lipid peroxides with an inhibition capacity of 0.93 mM gallic acid at 100 μg/mL (41). The FRAP assay indicated that the extract has the strong reducing ability at 2.7 and 3.0 times greater than that of the gallic acid and ellagic acid, respectively.…”

“…The extract showed good chelating activity of ferrous ions. An in vivo test on carbon tetrachlorideinduced oxidative stress in Swiss albino mice revealed that the extract has protective effects by decreasing the enzyme activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase in the blood, liver, and kidneys of the model mice [41].…”

Rhodomyrtus tomentosa is a common wood, prevalent in areas with undemanding soil conditions and resistant toward pests and diseases. The plant can be found in China, Taiwan, Philippines, Malaysia, Indonesia, and Vietnam. Literature and artwork indicate that R. tomentosa played an important holistic role in the daily lives of several ancient cultures, providing medicinal benefits. R. tomentosa exhibits a wide spectrum of pharmacological effects and has been used to treat colic diarrhea, wounds, heartburn, abscesses, gynecopathy, and as a pain killer. R. tomentosa was used in traditional Chinese medicine to treat urinary tract infection. 42 compounds have been isolated from this plant and structurally elucidated. They comprise phloroglucinol, flavonoid, terpenoid, anthracene glycoside, tannin, and other compounds. Rhodomyrtone, a member of the acylphloroglucinols demonstrated a significant activity against a wide range of Gram-positive bacteria. Rhodomyrtone exhibited both antimicrobial and anti-infective activities. Several biological activities have been documented as antibacterial, antifungal, antimalarial, osteogenic, antioxidant, and anti-inflammatory. R. tomentosa has been studied extensively for alternative antimicrobial agents. Although rhodomyrtone exhibited potential activity with a very low minimum inhibitory concentration value, the mechanisms of action of this compound are still unclear. Furthermore, toxicity studies on it extract to validate pharmacological activities are required.

“…The detection limit was 10 2 CFU/mL excellent antilisterial properties. The extract is rich in bioactive components including rhodomyrtone, displaying antibacterial potency against a wide range of Gram-positive organisms (Limsuwan et al 2009a, b) and flavonoid compounds which has earned recognition as free radical scavenging and antioxidant agents (Lavanya et al 2012). Previous in situ model system which rinsed hot dog contaminated with L. monocytogenes in a bath of 12% w/v Hibiscus sabdariffa calyces extract found 1.8-log and 2-log reduction in the bacterial cell numbers after rinsing for 60 min, before storage and after storage at 4°C for 24 h, respectively (Higginbotham et al 2014).…”

“…Higher a* and b* values observed with the treatments may be attributed to the carotenoid and flavonoid components of R. tomentosa leaves detected by the colour meter. The extract has been reported with abundant flavonoid components and tagged as a potent antioxidant (Lavanya et al 2012). Carotenoid component can also act against lipid oxidation of meat stored under aerobic condition (Muthukumar et al 2014).…”

Controlling foodborne pathogen in ready-to-eat food is important in food safety. The present study accessed the potential use of Rhodomyrtus tomentosa ethanolic leaf extract as a bio-control agent against Listeria monocytogenes in cooked chicken meat model system. The antilisterial activity of the plant extract was better under microwave condition and enhanced as storage temperature increased from 4 to 37°C. The extract could reduce L. monocytogenes numbers at low (10 4 CFU/g) and high (10 6 CFU/g) inoculum levels in cooked chicken by both rinse and injection application methods. A 5 min rinse in 8% w/v R. tomentosa extract reduced the bacterial number by C2-log before storage and C3-log after storage at 4°C for 5 days. Injection with 0.4% w/w R. tomentosa extract resulted in approximately 2-log reduction in the cell numbers both before and after storage at 4°C for 5 days. Five minutes rinse in the extract bath demonstrated better sensory preferences which were not significantly different from the control. Addition of black pepper powder to the extract rinsed samples improved odour but not appearance, colour, and texture preferences. Rhodomyrtus tomentosa extract was significantly effective for the bio-control of L. monocytogenes contaminations in cooked chicken meat model. The extract was observed as a potent bio-additive agent to control contaminations from L. monocytogenes and ensure safety in ready-to-eat meat.
