“…Moreover, given the low lignin content, the citrus peel can serve as a promising alternative to lignocellulosic biomass to produce biofuels [76]. Similar to citrus peel, the seeds are rich in nutritionally vital proteins [73], ascorbic acid [65], fatty acids, phytosterols and tocopherols, limonoids, dietary fibers, and flavonoids [65,77]. A comparative study among the seeds, peel, and pulp of fruits of three cultivars of mandarins, including Phlegraean mandarin (C. reticulata), kumquat (C. japonica), and clementine (C clementina), revealed that Phlegraean mandarin is richer in bioactive compounds, including total polyphenols (seeds > peel > pulp), antioxidant activity (seeds > peel > pulp), and ascorbic acid (seeds > peel > pulp) [65].…”

The increased consumption of fruits, vegetables, and whole grains contributes to the reduced risk of many diseases related to metabolic syndrome, including neurodegenerative diseases, cardiovascular disease (CVD), diabetes, and cancer. Citrus, the genus Citrus L., is one of the most important fruit crops, rich in carotenoids, flavonoids, terpenes, limonoids, and many other bioactive compounds of nutritional and nutraceutical value. Moreover, polymethoxylated flavones (PMFs), a unique class of bioactive flavonoids, abundantly occur in citrus fruits. In addition, citrus essential oil, rich in limonoids and terpenes, is an economically important product due to its potent antioxidant, antimicrobial, and flavoring properties. Mechanistic, observational, and intervention studies have demonstrated the health benefits of citrus bioactives in minimizing the risk of metabolic syndrome. This review provides a comprehensive view of the composition of carotenoids, flavonoids, terpenes, and limonoids of citrus fruits and their associated health benefits.

Gannan navel orange and Jinggang pomelo, belonging to the genus Citrus, are good sources of phenolic compounds, which are mainly concentrated in the peel. These phenolic compounds are considered promising in the prevention and treatment of non-alcoholic fatty liver disease (NAFLD). In order to maximize nutrients retention and bioactivity in the peel, pomelo peel and orange peel were processed using freeze-drying technology and mixed in the ratio (pomelo peel powder 50% and orange peel powder 50%) to make citrus peel powder (CPP). The purpose of this study was to explore new strategies and mechanisms associated with the consumption of CPP to alleviate nonalcoholic fatty liver injury, lipid metabolism disorders, and gut microbiota dysbiosis in obese mice induced by high-fat diet (HFD). The results showed that after 12 weeks of CPP administration, CPP supplementation had a strong inhibitory effect on HFD-induced weight gain, hepatic fat accumulation, dyslipidemia, and the release of pro-inflammatory cytokines. In particular, CPP modulates the composition of the intestinal flora, such as increasing the relative abundance of phylum Firmicutes, genus Faecalibaculum, genus Lactobacillus, genus Dubosiella, and genus Lachnospiraceae_NK4A136_ group and decreasing the relative abundance of phylum Bacteroidota, genus Helicobacter, and genus Bacteroides. These results suggest that CPP has a preventive effect on NAFLD, which can be related to the regulation of intestinal flora.

“…The lemon is the fruit of the lemon tree (Citrus lemon), which belongs to the Rutaceae family, originally from Southeast Asia, and is now widely planted throughout the Mediterranean littoral and anywhere else with a semi-tropical climate [16]. The leaves of citrus limon is known with a significant pharmacological and therapeutical important to improve the human health such as anti-tumor, antioxidative, anticancer, antiinflammatory, and antimicrobial activity due to heigh richess with secondary metabolites like flavonoids, phenolic acids, carboxylic acids, vitamins and other compounds [17][18][19]. These properties encourage as for use the citrus limon leaf extract for synthesis a silver nanoparticle with antioxidant and antimicrobial activity.…”

Due to its efficiency, eco-friendliness, non-toxicity, and cost-effectiveness, the utilisation of plant extracts in the manufacture of silver nanoparticles has garnered attention. The purpose of this study is to determine the feasibility of generating silver nanoparticles from an aqueous extract of Citrus limon leaves and their size and composition was characterized utilizing UV visible, FTIR, SEM, EDX, and Zeta seizer. Additionally, the antioxidant efficacy of Ag NPs was tested using the DPPH radical scavenging method, and their antibacterial activity was verified in vitro using the Agar well diffusion technique. Silver nanoparticles were successfully synthesized and exhibit surface plasmon resonance with an absorption maximum of 475.2 nm and the stabilization of the ions Ag to nanometric spherical negative charge particles, as verified by FTIR, MEB, EDX, and Zeta potential values. Furthermore, the silver nanoparticles created displayed a substantial bactericidal effect against the three types of bacteria (Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus) and an antifungal activity against (Candida albicans) as well as reasonable antioxidant properties.
