Antioxidant and Lipid-Lowering Effects of Buriti Oil (Mauritia flexuosa L.) Administered to Iron-Overloaded Rats. Molecules 2023; 28:molecules28062585. [PMID: 36985557 PMCID: PMC10056315 DOI: 10.3390/molecules28062585] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/27/2023] [Accepted: 03/09/2023] [Indexed: 03/14/2023] Open
Abstract
The indiscriminate use of oral ferrous sulfate (FeSO4) doses induces significant oxidative damage to health. However, carotene-rich foods such as buriti oil can help the endogenous antioxidant defense and still maintain other body functions. This study aimed to assess the effects of buriti oil intake in iron-overloaded rats by FeSO4 administration. Buriti oil has β-carotene (787.05 mg/kg), α-tocopherol (689.02 mg/kg), and a predominance of monounsaturated fatty acids (91.30 g/100 g). Wistar rats (n = 32) were subdivided into two control groups that were fed a diet containing either soybean or buriti oil; and two groups which received a high daily oral dose of FeSO4 (60 mg/kg body weight) and fed a diet containing either soybean (SFe) or buriti oil (Bfe). The somatic and hematological parameters, serum lipids, superoxide dismutase (SOD), and glutathione peroxidase (GPx) were determined after 17 days of iron overload. Somatic parameters were similar among groups. BFe showed a decrease in low-density lipoprotein (38.43%) and hemoglobin (7.51%); an increase in monocytes (50.98%), SOD activity in serum (87.16%), and liver (645.50%) hepatic GPx (1017.82%); and maintained serum GPx compared to SFe. Buriti oil showed systemic and hepatic antioxidant protection in iron-overloaded rats, which may be related to its high carotenoid, tocopherol, and fatty acid profile.

Abstract
Acute liver damage (ALD) can cause biochemical and pathological changes, which can lead to major complications and even death. The goal of the study was to examine the therapeutic efficacy of liposomes of Bergenia ciliata extract against thioacetamide-induced liver damage in rats. Liposomal batches of B. ciliata extract were prepared by altering the kind and amount of phospholipids and characterized through various physiochemical properties such as laser diffraction, TEM, encapsulation efficiency, stability and in-vitro release studies. In-vivo hepatoprotective studies were performed on TAA-induced acute hepatic damage model. Further, in-silico studies of bergenin against the three hepatic damage markers viz. TGF-β1, TNF-α and interleukin-6 were also performed. Laser diffraction and TEM showed that most stable liposome batch of B. ciliata extract were in the range of 678-1170 nm with encapsulation efficiency of 84.3±3.5. Extract was found to be rapidly dissociated from B. ciliata liposomes in HCl than PBS, according to in-vitro release data. In-vivo data revealed a significant decline in LFT indicators, amelioration of pathological changes and high bergenin bioavailability in the liposomal group. Protective activity of bergenin against ALD targets like TGF-β1, TNF-α and interleukin-6 was anticipated via molecular docking research. As a result, the current findings of the study indicate that B. ciliata liposomes and bergenin have promising ameliorative potential in the management of ALD.

Abstract
The impact of sugary maize dendrimer-like glucan octenyl succinate (OSA-SMDG) on the storage stability and antioxidant activity of β-carotene (BC)-loaded emulsions as well as bioaccessibility were investigated. The encapsulation efficiency of β-carotene in emulsions containing 3% OSA-SMDG (3OSA-SMDG-BC) or 5% OSA-SMDG (5OSA-SMDG-BC) was 89.6% and 94.9%, respectively. The antioxidant activity of both emulsions was higher than that of pure β-carotene. During simulated digestion, the particle size of emulsions was immediately reduced, whereas zeta-potential was continuously increased in intestinal digestion. After 2 h digestion, the free fatty acids (FFA) release rate of 3OSA-SMDG-BC and 5OSA-SMDG-BC was significantly higher than that of blank emulsion. Bioaccessibility of β-carotene encapsulated in 3OSA-SMDG-BC and 5OSA-SMDG-BC was also significantly higher than that of blank emulsion. FFA release rate and β-carotene bioaccessibility of 5OSA-SMDG-BC were higher than that of 3OSA-SMDG-BC. These results demonstrated that OSA-SMDG could be used to fabricate food-grade O/W Pickering emulsion as a delivery system for bioactive compounds.

Abstract
Due to population growth and global warming, the use of the sea water reverse osmosis process to obtain freshwater is increasing rapidly. A sustainable method with low environmental impact is limited for the management of brine with a high salt content, which is released as a result of the process. Some microalgae species can grow in salty environments and produce β-carotene. This study aims to evaluate the commercial potential of β-carotene production from microalgae grown in sea water reverse osmosis brine from a bioeconomy perspective. Synthetic media are often used for the production of β-carotene from algae, the use of sea water reverse osmosis brine is not common and the commercial potential of this application has not been evaluated before. In terms of the development of the β-carotene market, the strengths and weaknesses of the process, opportunities, and threats are thoroughly examined in this report. Also, with the use of sea water reverse osmosis, a daily 750 tons of algal β-carotene can be produced. The biotechnological production of microalgal β-carotene and the reuse of salt water within the scope of circular bioeconomy are seen as a sustainable solution due to the fact that the strengths of the process are dominant, and the market value of natural β-carotene is increasing day by day.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 264:113277.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Evodiae Fructus (EF), the traditional Chinese medicine, has been typically used to treat headache, abdominal pain, hernias, and menorrhagia for thousands of years. It is a mild toxicity herb-medicine listed in Sheng Nong's Herbal Classic. Recently, EF was reported to have toxicity or no toxicity in some investigations. Toxicity and approaches to reducing toxicity of EF are of great interest. Limonin (LIM), a major triterpenoid component of EF, also had various pharmacological activities such as anti-inflammatory, anticancer, and antioxidant effects. However, little attention was paid to the role of LIM in EF-induced hepatotoxicity. AIM OF STUDY The study aimed to address the problem of controversial hepatotoxicity of EF, evaluate the role of CYP3A4 inducer/inhibitor in EF-induced hepatotoxicity and disclose the effect of LIM in EF-induced hepatotoxicity. MATERIALS AND METHODS The chemical compositions and hepatotoxicity of small flower EF (SEF), medium flower EF (MEF), big flower EF (BEF) and the "organ knock-out" samples (the shell and seed part of BEF) were investigated. Simultaneously, C57BL-6 mice were randomly divided into four groups, which were given orally administered BEF, BEF in combination with dexamethasone (DEX), BEF in combination with ketoconazole (KTC), and BEF in combination with LIM, respectively. RESULTS In this study, more alkaloids and less LIM were detected in BEF compared with the compounds in SEF and MEF. Furthermore, we found that BEF group induced hepatotoxicity whereas no hepatotoxicity was observed in SEF and MEF groups. In addition, no LIM was detected in the shell part of BEF and five alkaloids were not detected in the seed part of BEF. Correspondingly, the shell part of BEF group induced hepatotoxicity whereas no hepatotoxicity was observed in the seed part of BEF group. It was also found that the BEF-induced hepatotoxicity was remarkably exacerbated when the mice were pretreated with DEX whereas the BEF-induced hepatotoxicity could be reversed by pretreatment with KTC or LIM. CONCLUSIONS Based on the results in this study, the misuse of BEF but not SEF and MEF could produce hepatotoxicity. The hepatotoxicity difference of different categories of EF might be associated with the relative contents of alkaloids and LIM. In addition, the results demonstrated that CYP3A4 inducer aggravated BEF-induced hepatotoxicity and LIM attenuated its hepatotoxicity.

Abstract
β-Carotene exhibits antioxidant and hepatoprotective activities via a multitude of biochemical mechanisms. However, the action mechanism involved in antioxidant and anti-inflammatory effects of this carotene in chronic liver diseases is not fully understood. In the present investigation, we have attempted to outline a plausible mechanism of β-carotene action against liver fibrosis in albino Wistar rats. To induce hepatic fibrosis, diethylnitrosamine (DEN) was administered in experimental rats for two weeks. DEN treated rats were divided into four groups, wherein each group comprised of five rats. β-Carotene supplement attenuated DEN-induced elevation in LFT markers (P < 0.05); averted depletion of glycogen (24%, P < 0.05) and, increased nitrite (P < 0.05), hydroxyproline (~67%, P < 0.05) and collagen levels (~65%, P < 0.05). Confocal microscopy of tissue sections stained with picrosirius red revealed accrued collagen in DEN-administered group, which was found to be reduced by β-carotene supplementation. Furthermore, β-carotene decreased the expression of iNOS/NOS-2 and NF-κB, as revealed by immunohistochemistry and Western immunoblotting. Collectively, these results demonstrate that β-carotene mitigates experimental liver fibrosis via inhibition of iNOS and NF-κB in-vivo. Thus, β-carotene may be suggested as a possible nutraceutical to curb experimental liver fibrosis.

Abstract
Introduction Introduction: noncommunicable diseases (NCDs) are the main cause of death worldwide. Secondary metabolites from plant sources such as Cnidoscolus aconitifolius may be used as adjuvants in the prevention of diseases related to oxidative stress and inflammation such as NCDs. Objective: the in vitro antioxidant and anti-inflammatory activities associated with biologically active compounds in C. aconitifolius extracts were evaluated. Method: the contents of phenols, flavonoids, flavonones and hydroflavonoles were determined. The potential antioxidant activity was determined with 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, and angiotensin-converting enzyme (ACE) activity. For anti-inflammatory activity quantitative PCR and enzyme-linked immunosorbent assay (ELISA) tests were used in macrophages derived from THP-1 monocytes and stimulated with LPS. Results: the aqueous extract recorded the highest phenolic content (70.61 0.07 g/100 g of extract), and the ethanolic extract registered the highest content in flavonoids (47.76 4.84 g/100 g of extract), flavonones and dihydroflavonoles (70.10 7.29 g/100 g of extract). The acetone extract obtained the highest DPPH inhibition (49.85 ± 5.30%), while the ethanolic extract showed the highest ABTS inhibition (41.01 ± 3.81%). The etanolic and aqueous extracts had the highest ACE inhibition. The ethanolic extract had the highest anti-inflammatory activity, decreasing gene expression for TNF- by 39.78% and for IL-6 by 97.81%, and their production by 46% and 48.38%, respectively, in macrophages stimulated with LPS. Conclusion: these extracts demonstrated in vitro their antioxidant and anti-inflammatory potential due to their content of bioactive compounds.

Abstract
Background and Aim The many pharmacological potentials of Stachytarpheta cayennensis (L.C. Rich) Vahl, especially in managing central nervous system disorders, hypertension, diabetes and infections, have made it a subject of abuse, necessitating the need to ascertain its safety. This study therefore investigated the toxic effects of the leaf extract of S. cayennensis in rats following acute and 28-day repeated doses in male and female rats. Experimental procedure Acute and repeated dose studies were conducted in male and female groups of rats (135–150 g), using OECD 423 and 407 Tests guidelines respectively. Functional observational battery, and body weights were monitored. Blood samples were analysed for haematological and plasma biochemical indices. Organs (brain, kidneys and liver) specimen were collected and weighed. Kidney and liver specimen were subjected to histopathological analysis. Results and conclusion The LD50 of the extract was greater than 5000 mg/kg, p.o. (24 h) suggesting that the extract may be non-toxic. However, following single and repeated doses, the results revealed varying degree of significant (p < 0.05) changes in biochemical and heamatological indices, as well as in relative body weight and organ-body and organ-brain weight ratios. Also, histological assessment revealed evidence of liver and kidney toxicities and recovery was incomplete, as signs of toxicities were still evident after 21 days of recovery. Therefore, the extract is potentially harmful to vital organs with evidence of sex differential adverse effects and non-reversible forms of toxicity, especially with repeated usage, necessitating the need to avoid indiscriminate use. The leaf extract of Stachytarpheta cayennensis induced significant changes in rats weights. The extract caused varying significant changes in biochemical and hematological indices. Significant alteration in histoarchitecture of liver and kidney were observed. The observed toxic effects were persistent following period of recovery. The toxic effects are mostly sex dependent.
