• Mechanism of Inhibitory Effect on Pulmonary Fibrosis: Study evaluated the inhibitory effects on pulmonary fibrosis of alkaline extract from ethanol extract of C. reticulata. Results showed the extract possessed an inhibitory effect on the proliferation of MRC-5 and a preventive effect on BLM-inducued pulmonary fibrosis in rats. The mechanisms of effects may be through upregulation of MMP-9 expression and inhibition of expressions of TNF-α and TIMP-1. (26)
• Suppression of LPS-Stimulated NO Production: Study evaluated evaluated the effects of nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in RAW 264.8 macrophage cells. Results showed C. reticulate may suppress LPS-stimulated NO production by inhibition of NF-kB. (27)
• Suppression of LPS-Stimulated NO Production: Alzheimer's disease (AD) is a major neuro-degenerative disease associated with reduced cellular level of choliinesterase, as well as formation and deposition of amyloid plaques (Aß) considered to play critical roles in the pathogenesis of AD. Study evaluated the BACE1 and ChE inhibitory properties of compounds from Cajanus cajan and Citrus reticulata, traditionally used in the management of neurodegenerative disease and their protective effects of chemical-induced cognitive impairment. Using in-silico methods, 119 compounds from C. cajan and C. reticulata were docked with AChE, BChE, and BACE1. Of the compounds screened, three showed remarkable binding affinity for the three protein targets. Compound 94, naphthalen-2-yl-acetic acid, 6-hydroxy-6-meth7yyl-cyclodecyl ester, from C. reticulata possibly contributed, at least in part to the neurotherapeutic potentials of the plant. (28)
• Wound Healing / Antioxidant / Peel Essential Oil: Study evaluated citrus peel derived essential oil for antibacterial and wound healing activity. Peels biomass of citrus fruits is usually considered garbage. Essential oil was recovered by hydrodistillation of freshly collected peels. GC-MS analysis showed various components dominated by D-limonene at 89.31%. Total flavonoid and phenolic contents were 14.63 ± 0.95 mg CE/g and 17.03% ± 3.24 mg GAE/g respectively. DPPH activity was 73.32% Antibacterial activity was higher against E. coli. In vivo studies showed significant reduction in wound diameter in EO treatment groups. The EO was non-irritant in draize scoring. (29)
• Anti-Leukemia Compounds / Pericarpium: Study evaluated the in vitro effects of extracts from the pericarpium of Citrus reticulata (cv Jiao Gam) on the growth and differentiation of murine myeloid leukemic cell clone WEHI 3B. The extracts not only inhibited the proliferation of JCS cells in a dose dependent manner, but also induced differential of JCS cells into macrophages and granulocytes. In vitro clonogenicity and in vivo growth of PCJR treated cells leukemic cells in BALB/c mice were significantly decreased. Survival rate of mice receiving PCRJ treated JCS tumor cells was increased. H-NMR, C-NMR, and GC-MS isolated two active components identified as nobiletin and tangeretin. (30)
• Antidiabetic / Antioxidant / Fruit Peel: Study evaluated the antihhyperglycemic and antioxidant effects of C. reticulata fruit peel hydroalcoholic extract and two flavonoids, hesperidin and quercetin in nicotinamide-STZ induced type 2 diabetic rats. GC-MS analysis yielded multiple flavonoids including hesperidin, quercetin, naringin, and polymethoxylated flavones (nobiletin and tangeretin). Results showed the fruit peel extract, hesperidin, and quercetin have potent antidiabetic effects, which may be mediated through insulinotropic effects and insulin-sensitizing actions. Also, the alleviation of the antioxidant defense system by the extract, hesperidin and naringin may enhance the antidiabetic actions and improve liver and kidney functions in NA/STZ-induced diabetic rats. (31)
• Facilitation of cAMP/PKA/ERK/CREB Signaling / /Nobiletin-Rich Peel Extract: cAMP/PKA/ERK/ CREB signaling linked to CRE-mediated trascription is crucial for learning and memory. Previous study found the natural compound nobiletin stimulates intracellular signaling and exhibits anti-dementia action in animals. Results suggest the four compounds (sinensetin, tangeretin, 6-demethoxynobiletin, and 6-demethoxytangeretin) and nobiletin in the Nchinpi extract mainly cooperated to facilitate potently CRE-mediated transcription linked to the upstream cAMP/PKA/ERK/CREB pathway in hippocammpal neurons. (32)
• Antiasthmatic / Alkaloid Compounds from Pericarpium: Stud evaluated the in vivo antiasthmatic activity of 'Chachi' using a histamine-induced experimental asthma model in Guinea pigs. Two alkaloid-type compounds were identified the alkaloid fraction: synephrine and stachydrine. The alkaloid fraction and synephrine showed dose dependent effect against histamine-induced experimental asthma. (33)
• Anticancer / Effect pm Sarcoma-180 Cells Cycle: Study evaluated the in vivo anticancer activity of C. reticulata extract in a tumor model of Sarcoma-180 cells, Heps cells, EAC cells implanted in mice.. The extract showed marked anticancer activity on Sarcoma-180 cells and Heps cells and no marked activity on EAC cells. There was induced apoptosis on Sarcoma-180 cells. (34)
• Protection of Uroepithelium Against UTI / Seeds: Study evaluated the protective effect of Citrus reticulata seed extract on the uroepithelium against urinary tract infection. Human bladder cell lines T24 and 5637 were used in a cell culture infection model. Results showed C. reticulata treatment decreased ß1 integrin expression. Citrus reticulata exhibited a protective effect on the uroepithelium as evidenced by reduced bacterial invasion of uroepithelial cells. Study suggest a therapeutic potential in preventing UTI. (35)
• Induced Apoptosis in Gastric Cancer Cells / Immature Peel: Study evaluated the antiproliferative effects of extract of immature tangerine peel on human gastric cancer cell line SNU-668.. At 50 µg/ml, the CR increased the apoptosis of human gastric cells with typical apoptotic characteristics,, including morphological changes of chromatin condensation and apoptotic body formation. There was reduced expression of BAX and CASP-3 protein expression. Results suggest induction of apoptosis through the caspase-3 pathway in human gastric cancer cell. (36)
• Serum Pharmacochemistry / Peel: Study evaluated the serum pharmacochemistry of extract from Citrus reticulata 'Chachi' peel using HPLC fingerprinting. Seventeen compounds absorbed into blood were found in medicated serum,. five of which were original constituents of the peel whiles might be metabolites. Polymethoxylated flavones, nobiletin and hesperetin could be bioactive components of the C. reticulata peel. (37)
· Antifungal / Polymethoxylated Flavones / Peel: Study of peels isolated polymethoxylated flavones (PMFs), identified and quantitated as tangeretin (33.87%), nobiletin (20.98%), 5-demethylnobiletin (3.52%), tetramethyl-o-scutellarein (1.61%),tetramethyl-o-isoscutellarein (1.23%), pentamethoxyflavone (1.08%), and sinensetn (0.35%). The PMFs showed antifungal activity against Aspergillus niger. The antfungal activity may be due to the permeability change of cytomembrane and the fragility of cell walls caused by chitin inhibition. (38)
· Effect of Heat Treatment on Anti-Inflammatory Effect / Peel: Respiratory tract infections are usually associated with induction of inducible nitric oxide synthase (iNOS) in inflammatory cells and increased airway production of nitric oxide (NO). The enhancing effect of heat treatment on the antioxidant effect of fruit peels has also been documented. This study evaluated the anti-inflammatory activities of heat-treated citrus peel extracts. Results showed significantly elevated anti-inflammatory activity of citrus peel after 100°C heat treatment in a time-dependent manner. The major NO-suppressing mechanism of the peel extract was inhibition of iNOS gene expression. (39)
· Cardiovascular Benefits Through Enzyme Inhibition / Peel: Study investigated the effect of methanolic extracts from citrus peels (Citrus limon/lime, C. reticulata/tangerine, Ci maxima/shaddock) on enzymes relevant to management of cardiovascular diseases (monoamine oxidase/MAO,, phosphodiesterase-5/PDE-5, and angiotensin-1converting enzyme/ACE). Results showed inhibition of MAO, PDE-5, and ACE and pro-oxidants induced lipid peroxidation in rat heart homogenate in a concentration-dependent manner. (40)
· Chemopreventive / Cancer Cell Proliferation and Migration / Fruit Flavonoids: Among different fruit parts viz. flavedo, albedo, segment membrane and juice sacs, flavedo showed significant inhibitory effect on three cancer cell lines (HepG2, HL-60, and MDA-MB-231). From the Ougan flavedo three flavanone glycosides, naringin, hesperidin neohesperidin, along with four polymethoxylated flavones (PMFs), sinensetin, nobiletin, tangeretin and 5-methoxynobiletin were purified from the flavedo. Cytotoxicity assay showed two flavanone aglycones and four PMFs exhibited significant antiproliferative activity on three cancer cells. Wound healing assay showed nobiletin and tangeretin exerted inhibitory effects on SKOV3 cell migration as well. Results showed the flavonoids may have preventive or therapeutic potential for inhibition of cancer cell proliferation and migration. (41)
· Antiobesity Therapy for Adolescents / Peel / Clinical Trial: A double-blind, placebo-controlled study investigated the potential benefits of water extract of C. reticulata peel on obesity and fat reduction in 40 adolescents from both sexes, aged 12-18. Group A received 800 mg of dry extract daily while group B received placebo, with both groups receiving three meals daily (2000 kcal/day). Results showed reduction in BMI, body fat percentage, and waist circumference along with reductions of total cholesterol and triglycerides in group A. The effects were attributed to the presence of polyphenols and flavonoids in the extract. Citrus peel extract is a cheap source of neutraceuticals and safe dietary means for management of obesity. (42)
• Anti-Hyperalgesic / Peels: Study evaluated the influence of ethanolic crude extract from peels of C. reticulata and possible mechanisms of action in different animal models of pain. The extract reduced hyperalgesic in the second phase of formalin test. the carrageenan model, and in Complete Freund's Adjuvant model. The possible contribution of opioidergic and adenosinergic systems in the anti-hyperalgesic effect was noted after treatment, with non-selective antagonists for both systems, which produced reversal effects.
