“…Recently, Fayemi et al analyzed the bioactivities of phytochemicals in C. citrinus against multi-resistant food borne pathogens, α-glucosidase, and MCF-7 cancer cell line, with promising results [ 13 ]. Antimicrobial activity of lyophilized extracts from flowers and leaves of C. citrinus has also been reported against Listeria monocytogenes in beef burgers [ 14 ]. The phytochemical screening showed the presence of polyphenols, alkaloids, monoterpenoids, aliphatic acids, tannins, sesquiterpenes, triterpenoids, and steroids in different parts of the plant (such as leaves, stem backs, flowers, and seeds [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]), showing the potential of this shrub for the development of products with health promoting properties.…”

Lemon bottlebrush (Callistemon citrinus (Curtis) Skeels) is one of the most common ornamental plants, diffused worldwide, and characterized by the presence of flowers with an intense red/purple coloration. There is increasing interest in the use and application of anthocyanins for their unique structural/chemical features in both food and pharmaceutical applications. RP-HPLC-DAD-ESI-MS/MS analysis of an enriched fraction of acidified methanolic extract of C. citrinus flowers allow the possibility of identifying, for the first time, the presence of four anthocyanins: cyanidin-3,5-O-diglucoside (cyanin), peonidin-3,5-O-diglucoside (peonin), cyanidin-3-O-glucoside, and cyanidin-coumaroylglucoside-pyruvic acid. Moreover, the evaluation of antioxidant and biological potential showed a remarkable activity of this fraction, able to actively scavenge DPPH, AAPH, and ABTS radicals, and to counteract the β-carotene-bleaching. In addition, it protects human mononuclear cells from oxidative injuries and prevents angiogenesis (acting in the range of few μg/ml); furthermore, it does not show significant iron-chelating ability (up to 200 µg/mL). The easy way of cultivation, robustness, and adaptability to different environments make the flowers of this plant a useful source of anthocyanins, with remarkable health promoting properties.

“…Also, Tseng &Tseng (1995) reported that both synthetic phenolic antioxidants BHA and BHT have also an antimicrobial effect against Penicillium islandicum. Several studies reported antimicrobial properties of natural extracts from some plants such as artichoke, Callistemon leaves, thyme, cinnamon, rosemary and green tea (Özvural et al, 2016;Gahruie et al, 2017;Fayemi et al, 2017 andErgezer et al, 2018). These evidences may explain the positive impact of BHA, BHT and MPE on suppression the developing of the microbial growth by progress of storage time in comparison to burgers of negative control (T1).…”

T HE impact of adding mango peel extract (MPE) on lipid oxidation, color deterioration, microbial stability and sensory properties of beef burgers stored at 4 ± 1 °C for 12 days was investigated. The MPE was incorporated into beef burger mix at 0.1, 0.2 and 0.3%, and compared with 0.01% butylatedhydroxyanisole (BHA)/butylatedhydroxytoluene (BHT) (1:1; positive control) and control (without any antioxidants; negative control).The results showed that mango peel powder contained high total phenolic content (TPC) (45.17 mg/g GAE) and antioxidant activity (92.05%). Also, the results showed that pH and color (L * , a * and b * ) values of MPE-containing burgers were lower than those of both controls. By the end of storage time, the (0.3%) MPE-containing burgers showed the lowest pH (6.03) and color (L * , a * and b * ) values (49.95, 11.51 and 10.38, respectively). Also, the (0.3%) MPE-containing burgers had higher TPC (121.85) and lower TBARS values (0.18) compared to the controls (29.57-60.65 mg GAE/100g and 0.19-0.20 mg malondialdehyde/kg, respectively). Consequently, adding the MPE enhanced the antioxidant activity and resulted in a significant inhibition of total aerobic count in comparison to both controls. The results obtained from sensory analyses revealed that adding the MPE to beef burgers was effective with regard to retarding color and taste deterioration, and rancid odor formation. The (0.1%) MPE-containing burgers had the highest overall sensory scores. The results obtained from this study showed that MPE can be an effective additive with regard to retarding deterioration of quality characteristics during the cold storage of beef burgers.

“…Australian Aborigines even suck the nectar from flowers for the production of sweet drinks due to its refreshing flavour [15]. Antimicrobial activity of lyophilized extracts from flowers and leaves of C. citrinus inhibits the growth of Listeria monocytogenes in beef burgers [21]. Either in dietary or non-dietary form, natural antioxidants can reduce oxidative stress [22] and prevent oxidative rancidity in fat-based foods, meat and dairy products [23,24].…”

This study investigates in-vitro activities of phytochemicals in Callistemon citrinus against multiresistant foodborne pathogens, alpha-glucosidase enzyme and MCF-7 cancer cell line. Assays were prepared with lyophilized extracts to determine antioxidant capacity, inhibition of a-glucosidase enzyme and growth of foodborne bacteria. Annexin-V detection kit was used for apoptosis detection and FT-IR spectroscopy to confirm structural and functional groups of phytochemicals. Cytotoxicity of the extracts against MCF-7 cells was monitored with xCELLigence Real-Time Cell Analyser. The result from FT-IR analysis gave a peak at 3295 cm À1 wavenumber, confirming the presence of O-H alcohol functional group. FT-IR analysis also showed the presence of different functional groups such as carboxylic acids, aromatics, alkanes, alcohols, aliphatic amines, alkenes and amine groups in the extracts. Callistemon exhibited strong antioxidant capacities with EC 50 values of 0.474 ± 0.03 and 0.787 ± 0.15 mL sample/g of 2,2-diphenyl-1-picrylhydeazyl (DPPH) from leaf and flower extracts, respectively. Growth inhibition of most gram-positive foodborne bacteria by phytochemicals from flower extract appeared more promising as an alternative antimicrobial agent for food preservation. IC 50 value of 3.69 ± 0.61 lg/mL obtained from leaf extract showed its inhibitory potential against a-glucosidase enzyme for managing diabetes type-2. A dose response obtained from real-time monitoring with xCELLigence system indicated higher cytotoxicity of the extracts against MCF-7 cell line at !200 lg/mL concentrations within 24 h of incubation. The versatility of phytochemicals in Callistemon observed in this study signifies its potential for enhancing feed or food functionality, moderating blood glucose level and inhibiting the growth of foodborne pathogens or invasive carcinoma in man.
