Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Dill seed oil as a possible contraceptive agent: antiangiogenic effects on endothelial cells

Abstract Dill (Anethum graveolens L.) essential oil is wide spread in the food, beverage and pharmaceutical sectors. Dill is a member of the Apiaceae (Umbelliferae) family. It has the following biological activities: antioxidant, antifungal, antibacterial, antimicrobial, antihyperlipidemic, antihypercholesterolemic, antispasmodic, antiproliferative and anti-inflammatory. Aqueous extract of dill seed has reported effects on sex hormones and infertility potential. Moreover, boiled dill seed has an impact on reducing labor duration in giving birth. Implantation and placentation are necessary for a healthy pregnancy in the early stages. Angiogenesis is responsible for these essential processes. This study aimed to investigate dill seed oil's cytotoxic and antiangiogenic effects on rat adipose tissue endothelial cells (RATECs). Dill seed oil showed dose-dependent cytotoxicity on RATECs. It disrupted endothelial tube formation and depolymerized F-actin stress fibers. According to this study, depolymerization of F-actin stress fiber by dill seed oil could inhibit angiogenesis by suppressing endothelial cell proliferation, tube formation and motility. In other words, dill seed oil can be a new anti-angiogenic agent and a novel contraceptive.

Functional and chemical qualities of Vitis labrusca grape seed oil extracted by supercritical CO 2 / Calidad funcional y química del aceite de semilla de Vitis labrusca extraído mediante CO 2 supercrítico / Qualidade funcional e química do óleo de semente de Vitis labrusca extraído por CO 2 supercrítico

Abstract Grape seed oil, which is usually extracted with highly toxic organic solvents that are harmful to human health, is produced from tons of grape pomace waste, generated during winemaking. Sometimes, this waste is used to make compost or is burnt, which causes environmental contamination. The functional qualities, antioxidant capacity (AC), α-tocopherol and total phenolic compounds content (TPC) of Black Borgoña (Vitis labrusca) grape seed oil, extracted by supercritical CO2, were evaluated. The high content of linoleic acid (ω-6) and monounsaturated fatty acids contributed to the beneficial effect on the functional quality indices, which were 0.20, 0.23, 11.80 for IA, IT and H:H, respectively. In addition, a POV of 6.23 ± 0.08 milliequivalents of peroxide/kg oil and an anisidine index of 2.70 ± 0.05 indicated a good quality oil. Also, a high concentration of a-tocopherol (9.82 ± 0.02 mg/100 g oil) and a high TPC ("4.14 ± 3.24 mg GAE/kg oil) were obtained. This study demonstrated that supercritical CO2 extraction is a suitable method for the delivery of a high-quality grape seed oil.

Development of preparation process of icaritin-coix seed oil microemulsion based on quality by design concept / 中国中药杂志

To optimize the formulation and preparation process of icaritin-coix seed oil microemulsion(IC-MEs) based on quality by design(QbD) concept. IC-MEs were prepared by water titration. Firstly, the risk factors that may affect the quality of IC-MEs were evaluated. Then Plackett-Burman design was used to screen out prescription factors and process parameters that had a significant effect on the indicators. Finally, Box-Behnken design was used to optimize the prescription ratio of IC-MEs. Through the risk assessment and Plackett-Burman design, three formulation factors [drug loading efficiency, the ratio of mixed-oil(coix seed oil-Glycerol tributyrate) to mixed-surfactant(HS15-RH40) and water addition] were determined as the key factors affecting IC-MEs. The regression model established by Box-Behnken design had a good predictability. The optimal formula was as following: the drug loading efficiency of 0.92%, the ratio of mixed-oil(coix seed oil-glycerol tributyrate) to mixed-surfactant(HS15-RH40) of 4∶6, and the water addition of 5.7 mL. According to this prescription, IC-MEs were prepared, and its encapsulation efficiency after 1 week was 92.45%±1.00%. Therefore, the stability of IC-MEs could be improved by optimizing prescription and process parameters of IC-MEs based on the QbD concept, which can provide certain reference value for the future development of IC-MEs.

Peptic Ulcer Healing Activity Of Fruit Pulp Extract And Seed Oil Of Adansonia Digitata Linn

Adansonia digitata (AD) Linn has been used to cure PU in Ayurveda but its efficacy has not been validated. The current study was so carried out to evaluate the antiulcer activity of ethanolic extract of Adansonia digitata fruit pulp (ADFP), n hexane extract of Adansonia digitata seed oil (ADSO) & their combination (ADFP+ADSO) in rats. The effect of AD on gastric ulcer in pylorus ligation induced and ethanol induced models was studied using doses [ADFO (500 mg/kg), ADSO (300 mg/kg) & combination of ADFP & ADSO] for 10 days. Omeprazole (10 mg/kg) were used as the standard drug. Depending on the model, outcomes measures were gastric volume, pH, free acidity, total acidity, ulcer index, percentage inhibition of ulcer index, protein, pepsin, mucus, antioxidant marker enzyme level (Superoxide dismutase, Catalase, Lipid peroxidation), morphological & Histopathological study. The result obtained with combination was set up near to the standard drug and consequence showed that the combination of ADFP & ADSO was found to be more effective than the individual extract of AD. The outcomes were statistically evaluated with the one-way ANOVA followed by the test of Dennett’s‘t’. The secondary-metabolites such as flavonoids, proteins, saponins, tannins, phenols, terpenoids, alkaloids and Fatty acids (palmitic acid, oleic acid, linoleic acid) are potent as antioxidant, antiulcer and anti-inflammatory. The finding of this reading confirmed that AD has antiulcer activity due to 1 or more of the secondary-metabolites present in it. Therefore, this study validates its antiulcer use in Ayurveda. Future investigation on separation of specific phytochemicals and elucidate MOA are needed.

The order of the effectiveness of reducing capabilities of the oils was found to be N. lotusseed oil > ascorbic acid> N. pubescensseedoil.Gas chromatographic coupled mass spectroscopy analysis of the N. lotusseed oil showed that Dihydrocarveol (0.87%), Eicosane (1.10%), Lupeol (14.75%), Tetracosane (2.14%) and Viridiflorol (13.72%) were the major antioxidants compounds identified whereas Palmitic acid (23.57), Eicosane (7.65%), Oleic acid (37.85%), Tetracosane (3.10%) and Squalene (1.58%) were the major antioxidants detected in N. pubescensseed oil. Compared with standard (ascorbic acid), the results show that N. lotusseed oil possessed highest antioxidant potential. The higher antioxidant potential displayed by Nymphaea lotusseed oil could be attributed to the presence of these compounds that could act synergistically.Conclusion:Therefore, Nymphaea lotus seed oil and Nymphaea pubescensseed oil contains natural antioxidants that can improveoxidative stability.

Hepatoprotective effect of Opuntia dillenii seed oil on CCl4 induced acute liver damage in rat

Objective: To investigate the hepatoprotective effect of Opuntia dillenii seed oil (ODSO) on CCl4 provoked liver injury in rat. Methods: Animals were treated orally with ODSO at a concentration of 2 mL/kg, once daily for one week before the first intraperitoneal injection of CCl4, and thereafter the administration of the oil was continued for 7 days until the introduction of the second injection of CCl4. Fourteen hours after the last dose of CCl4, rats were sacrificed, and the relative liver weight, weight gain, alkaline phosphatase, aspartate amino transferase, alanine aminotransferase, direct bilirubin, total bilirubin, triglycerides, total cholesterol, very low density lipoprotein, low density lipoprotein, high density lipoprotein, plasmatic glucose, urea, creatinine, acid uric and malondialdehyde were determined. Results: The significant increase was found in relative liver weight and plasma levels of alanine aminotransferase, aspartate amino transferase, alkaline phosphatase, total bilirubin, direct bilirubin, triglycerides, very low-density lipoprotein, urea, uric acid and malondialdehyde. Likewise, the significant decrease was indicated in the weight gain and the level of glucose plasmatic, and high-density lipoprotein levels in CCl4 produced liver injury in rats were re-established to normal levels when treated with ODSO.While, no change was observed in the total cholesterol, low-density lipoprotein and creatinine in all animals. Conclusions: We conclude that the ODSO has a protective effect on CCl4-mediated liver injury. Hence, we suggest its inclusion as a preventive control of liver disorders.

Impact of Coix seed oil on fluorescence excretion pharmacokinetics and protein expression in doxorubicin-resistant cells MCF-7/DOX / 药学学报

This study was designed to explore the mechanism of Coix seed oil (Coix) impact on the drug resistance, bioluminescence imaging (BLI) and the efflux of D-luciferin potassium salt, the substrate of ABC transporters, in doxorubicin-resistant breast cancer cells. Multidrug resistance (MDR) gene and protein expression were analyzed in the cells by q-PCR and Western blot. First, in order to investigate the effect of the efflux function by ABC protein, a cell line with overexpressed luciferase was established in MCF-7 cell line. BLI was used to monitor the efflux kinetics of D-luciferin potassium salt before and after Coix treament. The results showed that the efflux of D-fluorescein potassium from MCF-7/DOXFluc was lessened when pretreated with Coix, which means that Coix may decrease the efflux of other chemotherapies using ABC transporters. Both of the results of q-PCR and Western blot showed that gene and protein expression of ABC transporters such as ABCG2, ABCC1 and ABCB1 were down-regulated by Coix treatment. The efficacy of Coix reversing MDR was verified with the chemotherapy medication doxorubicin (DOX). MTT assay showed that Coix increased the inhibitory effect of DOX on proliferation of MCF-7/DOX, and the optimal combination of ratio was 25 times that of DOX. The results suggest that Coix may reverse MDR of the substrate of ABC transporters from two aspects, one is to cut down the ABC protein efflux function, and the other is to decrease the quantity of ABC gene and protein expression.
