“…In the citrus × clementina pulp extracts, the total antioxidant capacity (TAC) was found to be three-fold higher (7.1 mmol TE/mg fresh weight [FW]) compared to Citrus reticulata (2.6 mmol TE/mg FW) and six-fold higher compared to Citrus japonica (1.2 mmol TE/mg FW). Similarly, Citrus sinensis and Citrus reticulata fruits possessed good antioxidant activity studied by the hydroxyl radical scavenging activity and reducing power capacity methods (Bentahar et al, 2020). Fratianni et al (2019) indicated that Citrus bergamia and Citrus medica cv.…”

Citrus is the most cultivated fruit crop in the world and occupies a place of considerable importance in the country’s economy. Almost 33% of the citrus fruits are processed for juice production; however, a great amount of wastes, including peels, segment membranes, and seeds are also produced. Indeed, citrus fruits consist of 45% juice, 26% pulp, 27% peels, and 2% seeds. Pruning, a cultural practice involving the removal of tree branches and limbs, was applied to improve fruit’s quality. A large amount of leaves are produced through pruning. These agri-food matrices contain a wide range of bioactive phytochemicals compared to fruits. The present review covers the past 5 years of research carried out in chemistry, health properties, and applications in food and nutraceutical industries of all portions of citrus fruit and its major bioactive compounds. Additionally, patents are also included.

“…In addition, luteolin, Apigenin, Genkwanin were found for the species Rosmarinus officinalis L. and diosmetin, naringin, tangeretin, quercetin, nobiletin and narirutin for Citrus × sinensis . Phenolic acids were found in two species, Gallic acid, Caffeic acid, Ferulic acid, Coumaric acid, caffeic acid, found in in higher concentrations in Citrus × sinensis and, naturally, rosmarinic acid (only present in Rosmarinus officinalis L. species), found in higher concentrations in the other species mentioned [ 61 , 62 , 63 ]. Typical phenolics with antioxidant activity are primarily flavonoids (as we have mentioned) and phenolic acids.…”

“…Although hesperidin is the major flavonoid in both species, it is found in higher concentrations in the species Rosmarinus officinalis L. than in Citrus × sinensis , which has more types of flavonoids; therefore, the concentrations are more dispersed. This may be a possible justification for the small difference in IC 50 [ 61 , 62 , 63 ]. Furthermore, an important difference between these two compounds is the presence of rosmarinic acid in only one of the species.…”

“…This structure is also present in some rosmarinic acid derivatives, such as ferulic acid (also present in Citrus × sinensis ), which demonstrates a comparable oxidizing activity. However, this antioxidant capacity in ferulic acid is modified by O-methylation, which makes it less active [ 61 , 62 , 63 , 64 ]. Thus, it is possible to understand why the species Rosmarinus officinalis L. has a lower IC 50 than Citrus × sinensis .…”

Automatic Identification of Myeloperoxidase Natural Inhibitors in Plant Extracts

The aim of this study is the development of an automated method for myeloperoxidase activity evaluation and its application in testing the inhibitory action of different plant extracts on the activity of the enzyme. This enzyme has its concentration increased in inflammatory and infectious processes, so it is a possible target to limit these processes. Therefore, an automatic sequential in-jection analysis (SIA) system was optimized and demonstrated that it is possible to obtain results with satisfactory accuracy and precision. With the developed method, plant extracts were studied, as promising candidates for MPO inhibition. In the group of selected plant extracts, IC50 values from 0.029 ± 0.002 mg/mL to 35.4 ± 3.5 mg/mL were obtained. Arbutus unedo L. proved to be the most inhibitory extract for MPO based on its phenolic compound content. The coupling of an automatic SIA method to MPO inhibition assays is a good alternative to other conventional methods, due to its simplicity and speed. This work also supports the pharmacological use of these species that inhibit MPO, and exhibit activity that may be related to the treatment of infection and inflammation.

“…The nutritional benefits of citrus fruit consumption on human health are well demonstrated (Campone et al, 2020). C. sinensis has been used in traditional medicine to treat medical conditions such as constipation, cramps, colic, diarrhea, bronchitis, tuberculosis, cough, cold, menstrual disorder, angina, hypertension, anxiety, depression and stress (Favela-Hernández et al, 2016;Bentahar et al, 2020). In addition, these fruits are used also to treat bowel disorders, respiratory disorders, cardiovascular disease, and stress (Mannucci et al, 2018).…”

Hyperhomocysteinemia is considered to be one of the risk factors for inflammatory bowel disease (IBD), it is a chronic, relapsing, and remittent inflammatory disease of the gastrointestinal tract. Citrus sinensis L. has been used traditionally to treat bowel disorders. The present study aims to quantify the phenolic and flavonoid contents of the Citrus sinensis L. fruit (ORF) extract and to evaluate in vitro the antioxidant activity and the anti-inflammatory effect of ORF in vivo on intestinal inflammation induced by hyperhomocysteinemia. The total phenolic and flavonoid contents of the extract were determinated using the spectrophotometric method and the evaluation of antioxidant activity was performed by four methods: DPPH, ABTS, CUPRAC, and reducing power. The inflammatory marker (plasma homocysteine), the reduced glutathione (GSH) content in the liver tissue were measured and the histological sections of the intestines of the mice used were examined to assess the anti-inflammatory activity of ORF. The results of this study showed that the ethanolic extract of ORF possessed high phenolic content and exhibited good antioxidant activity. The use of ORF powder in the in vivo study showed an increase in GSH levels, a decrease in plasma homocysteine levels, and a restoration of the integrity of the intestinal epithelium.
