Nanoemulsion containing Jatropha gossypiifolia leaf extract reduces dermonecrosis induced by Bothrops erythromelas venom and accelerates wound closure. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118188. [PMID: 38608797 DOI: 10.1016/j.jep.2024.118188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 04/02/2024] [Accepted: 04/09/2024] [Indexed: 04/14/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The species Jatropha gossypiifolia, popularly known as "pinhão-roxo", is distributed throughout Brazil, is commonly employed for topical or oral administration in treating wounds, inflammations, and snake bites. Given the significant impact of snakebites on public health and the limitations of antivenom, coupled with the diverse molecular composition of this plant species, investigating its healing and antidermonecrotic capacities is relevant. AIM OF THE STUDY This study aimed to develop a topical nanoemulsion incorporating the hydroethanolic extract of J. gossypiifolia leaves, to evaluate its therapeutic potential, particularly in terms of its efficacy in wound healing and inhibition of dermonecrosis induced by B. erythromelas venom (BeV). MATERIAL AND METHODS The extract of J. gossypiifolia (JgE) leaves was obtained by maceration and remaceration. The phytochemical analysis was conducted and J. gossypiifolia nanoemulsion (JgNe) was obtained, characterized and assessed for stability. The cytotoxicity was determined in normal cells (erythrocytes and 3T3) using hemolytic assay and cell viability assay using crystal violet staining. The antioxidant activity was evaluated by the reduction of ABTS and DPPH radicals. The evaluation of wound healing was conducted in vivo following treatment with JgNe, wherein the percentage of wound closure and inflammatory mediators. The skin irritation test was assessed in vivo by applying JgNe directly to the animal's skin. In vitro, the antivenom capacity was evaluated through enzymatic inhibition assays (phospholipase A2 and hyaluronidase) of BeV. Additionally, the in vivo antidermonecrotic activity of JgNe was evaluated by measuring the reduction of the dermonecrotic halo. RESULTS The HPLC-DAD analysis identified flavonoids, specifically vitexin, luteolin derivatives and apigenin derivatives. In addition, 95.08 ± 5.46 mg of gallic acid/g of extract and 137.92 ± 0.99 mg quercetin/g extract, was quantified. JgNe maintained stability over a 4-week period. Moreover, JgE and JgNe demonstrated no cytotoxicity in human erythrocytes and murine fibroblasts at tested concentrations (32.25-250 μg/mL). Additionally, exhibited significant antioxidant activity by reducing ABTS and DPPH radicals. The treatment with JgNe did not induce skin irritation and accelerated wound healing, with significant wound closure observed from 5th day and reduction in nitrite levels, myeloperoxidase activity, and cytokine. Both JgE and JgNe demonstrated in vitro inhibition of the phospholipase and hyaluronidase enzymes of BeV. Moreover, JgNe exhibited antidermonecrotic activity by reducing the dermonecrotic halo caused by BeV after 24 h. CONCLUSIONS JgNe and JgE exhibited no cytotoxicity at the tested concentrations. Additionally, our findings demonstrate that JgNe has the ability to accelerate wound closure and reduce dermonecrosis caused by BeV, indicating to be promising formulation for complementary therapy to antivenom treatment.

Cytotoxic and antiviral activities of Jatropha variegata and Jatropha spinosa in relation to their metabolite profile. Sci Rep 2024; 14:4846. [PMID: 38418513 PMCID: PMC10902333 DOI: 10.1038/s41598-024-55196-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 02/21/2024] [Indexed: 03/01/2024] Open
Abstract
Jatropha variegata and Jatropha spinosa (family: Euphorbiaceae) are utilized in Yemeni traditional medicine to treat respiratory tract infection and in different skin conditions such as wound healing, as antibacterial and hemostatic. In this study, we evaluated the cytotoxicity and the antiviral activities of the methanolic J. variegata (leaves: Ext-1, stems: Ext-2, and roots: Ext-3), and J. spinosa extracts (aerial parts: Ext-4 and roots: Ext-5), in addition to their methylene chloride fractions of roots extracts (F-6 and F-7, respectively). All samples were tested against three human cancer cell lines in vitro (MCF-7, HepG2, and A549) and two viruses (HSV-2 and H1N1). Both plants showed significant cytotoxicity, among them, the methylene chloride fractions of roots of J. variegata (F-6) and J. spinosa roots (F-7) showed the highest activity on MCF-7 (IC50 = 1.4 and 1 μg/mL), HepG2 (IC50 = 0.64 and 0.24 μg/mL), and A549 (IC50 = 0.7 and 0.5 μg/mL), respectively, whereas the IC50 values of the standard doxorubicin were (3.83, 4.73, and 4.57 μg/mL) against MCF-7, HepG2, and A549, respectively. These results revealed that the roots of both plants are potential targets for cytotoxic activities. The in vitro results revealed potential antiviral activity for each of Ext-3, Ext-5, F-6, and F-7 against HVS-2 with IC50 of 101.23, 68.83, 4.88, 3.24 μg/mL and against H1N1 with IC50 of 51.29, 27.92, 4.24, and 3.06 μg/mL respectively, whereas the IC50 value of the standard acyclovir against HVS-2 was 83.19 μg/mL and IC50 value of the standard ribavirin against H1N1 was 52.40 μg/mL .The methanol extracts of the roots (Ext-3 and Ext-5) of both plants were characterized using UPLC/MS. A total of 73 metabolites were annotated, including fourteen diterpenoids, eleven flavonoids, ten phenolic acid conjugates, twelve fatty acids and their conjugates, five triterpenes and steroids, two sesquiterpenes, and six coumarins. The cytotoxicity and antiviral activities determined in the present work are explained by the existence of flavonoids, coumarins and diterpenes with commonly known cytotoxicity and antiviral activities.

Abstract
BACKGROUND Diabetes mellitus (DM) is a metabolic disorder known to impair many physiological functions via reactive oxygen species (ROS). Aldose reductase, sorbitol dehydrogenase, dipeptidyl peptidase IV, α-amylase and α-glucosidase are pharmacotherapeutic protein targets in type-2 diabetes mellitus (T2DM). Inhibitors of these enzymes constitute a new class of drugs used in the management and treatment of T2DM. Some reports have claimed that medicinal plant extracts that serves as food (and as an antioxidant source) can reduce these alterations by eliminating ROS caused by DM. Ethnobotanical survey claims Jatropha gossypifolia commonly called "fignut" and "Lapa-lapa" in the Yoruba land of South-western Nigeria, to be used for the treatment and management of diabetes, in addition to its nutritive value. OBJECTIVE The nutritional composition and in-silico antidiabetic potential of the bioactive constituents of J. gossypifolia leaf extracts were investigated. METHODS Proximate, minerals and gas chromatography-mass spectroscopy (GC-MS) analysis were carried out using standard procedures. Phytocompounds present in J. gossypifolia methanol (JGM) and ethyl acetate (JGE) leaf extracts were tested as potential antagonists of selected protein targets via in-silico techniques. Drug-likeness, pharmacokinetic properties and toxicity of the promising docked ligands were also predicted. RESULTS The proximate and mineral analysis revealed good nutritional composition and mineral content. Additionally, cyclo-pentadecane and dibutyl phthalate from methanol extract, and benzene- 1,2,4,5-tetramethyl, benzene-1,2,3,5-tetramethyl, and benzene-1,3-dimethyl-5-(1-methylethyl) from ethyl acetate extract were present in J. gossypifolia leaf which exhibited a better binding affinity than the clinically prescribed standard, metformin. CONCLUSION Benzene-1,2,4,5-tetramethyl from JGE extracts exhibited the most promising antidiabetic potential in-silico, suggesting its candidature as diabetes-target-protein inhibitor which may be developed for the treatment of type-2 diabetes mellitus.

Abstract
Jatropha, a traditional medicinal plant known for its anti-inflammatory, antimicrobial, anticancer, antiviral, antidiabetic, and anticoagulant properties, was the subject of our study. We examined the morphology and chemical composition of three Jatropha species using cross- and longitudinal sections of fresh samples, observed with light microscopy. Histochemical analysis was conducted using various reagents to reveal the metabolites present. Anatomically, the distinguishing feature among the three Jatropha species was the presence of secretory cavities. These structures were identified in the petiole and stem bark of J. multifida, while in J. gossypiifolia and J. curcas they were present in roots. The stem bark cells of J. gossypiifolia were roundish in shape, whereas the others were rectangular. Laticifers were detected in the leaves, petioles, and stem bark of all three Jatropha species, while idioblasts were present in almost all organs. Histochemical tests revealed that excretory idioblasts and laticifers in Jatropha species contained alkaloids, phenolics, lipophilic compounds, and terpenoids. The cuticle of non-glandular trichomes contained terpenoids, while phenolic compounds were found within the secretory cavities. These findings contribute to the identification of Jatropha species and provide valuable insights for the selection and collection of specific plant organs containing bioactive compounds.

Abstract
Background Acetaminophen-induced liver injury remains a significant public health problem because available treatments are limited due to their adverse effects. Medicinal plants, which are an important source of bioactive molecules, could be an alternative treatment for liver disease. Objective This study was designed to investigate the curative effect of aqueous extracts of Cissus quadrangularis (Vitaceae) and Jatropha gossypiifolia (Euphorbiaceae) on acetaminophen-induced liver injury in mice. Methods Mice were divided into groups and treated with distilled water, silymarin (50 mg/kg), a reference hepatoprotective agent, and aqueous extracts of C quadrangularis and J gossypiifolia (50 and 100 mg/kg, PO, respectively). These substances were given as a single daily dose 4 hours after acetaminophen administration (300 mg/kg, PO) for 2 days. Mice were humanely put to death 24 hours after the last dose and serum alanine aminotransferase and aspartate aminotransferase activities, total bilirubin and protein levels, reduced glutathione, superoxide dismutase, malondialdehyde, catalase, and nitrite tissue levels were assessed. Histology of the livers of the mice was performed by hematoxylin and eosin staining. Results Acetaminophen administration induced a significant (P < 0.05) mean (SEM) body weight loss (-14.45% [5.92%]), a significant elevation of alanine aminotransferase activity (15.08%), total protein and bilirubin levels (25.80%), and a significant (P < 0.05) increase in liver superoxide dismutase (67.71%), catalase (63.00%), glutathione (40.29%), malondialdehyde (30.67%), and nitrite levels compared with the control group. In curative treatment, C quadrangularis and J gossypiifolia (50 and 100 mg/kg) significantly (P < 0.05) reduced mean (SEM) body weight loss (16.67% [7.16%] and 1.25% [0.51%], respectively), serum alanine aminotransferase activity (17.62% and 11.14%, respectively), bilirubin level (29.62% and 49.14%, respectively) compared with acetaminophen group, and J gossypiifolia normalized serum total protein level. Both extracts significantly (P < 0.05) reduced the levels of glutathione and malondialdehyde and normalized that of nitrite, superoxide dismutase, and catalase compared with the acetaminophen group. Hepatocyte necrosis and inflammatory cell infiltration were remarkably reduced by the plant extracts. Conclusions The results obtained are evidence in favor of the development of a formulation based on the extracts of these plants against liver diseases.

Abstract
The utilization of plants with medicinal properties is deeply rooted in the traditional knowledge of diverse human populations. This study aims to investigate the cytotoxicity of nine plants commonly used by communities in San Basilio de Palenque, Bolivar (Colombia), for managing inflammation-related illnesses. Hydroethanolic extracts from various plant parts such as roots, stems, barks, or leaves were prepared through a process involving drying, powdering, and maceration in an ethanol-water (7:3) solution. The extracts were subsequently freeze-dried and dissolved in DMSO for the bioassays. Cytotoxicity against the human hepatoma HepG2 cell line was assessed using the MTT assay, with extract concentrations ranging from 0 to 500 µg/mL and treatment durations of 24 and 48 h. The total phenolic content of the nine extracts varied from 96.7 to 167.6 mg GAE/g DT. Among them, eight hydroethanolic extracts from Jatropha gossypiifolia L., Piper peltatum L., Malachra alceifolia, Verbesina turbacensis, Ricinus communis, Desmodium incanum, and Dolichandra unguis-cati showed low toxicity (IC50 > 500 µg/mL, 24 h) against HepG2 cells. On the other hand, the extracts of Aristolochia odoratissima L. (IC50 = 95.7 µg/mL) and Picramnia latifolia (IC50 = 128.9 µg/mL) demonstrated the highest cytotoxicity against the HepG2 cell line, displaying a modest selectivity index when compared to the HEKn cell line after 48 h of treatment. These findings suggest that medicinal plants from San Basilio de Palenque, particularly Picramnia latifolia and Aristolochia odoratissima, have potential activity against cancer cells, highlighting their potential for further research and development.

Abstract
We assessed bioactivity of ethanolic extracts from 35 species of Jatropha L. against an ornamental plant pest, the azalea lace bug, Stephanitis pyrioides (Scott). Jatropha extracts were prepared by air-drying stem, root, or whole plant material, grinding the tissue into a fine powder, adding 70% ethanol, and then vacuum filtering the contents. Emulsions included the extract diluted to the desired concentration in de-ionized water and 10% dimethyl sulfoxide (DMSO). Treatments involved pipetting 20 µl of emulsion onto three adult lace bugs in each well of a 96-well microtiter plate. Treated wells served as replicates for each of six extract concentrations and were arranged according to a RCBD. Extracts of Jatropha clavuligera Müll. Arg. and J. ribifolia (Pohl) Ballion from 0.06 to 0.50% were the most acutely bioactive with bug mortality exceeding that of the positive control - azadirachtin, a terpenoid and chief active ingredient in neem oil. At 1.00%, extracts of J. clavuligera, J. ribifolia and azadirachtin killed 100% of bugs within 3 hr. Jatropha clavuligera induced the lowest LC50 and ranked first in insecticidal potency based on ≥98% of bugs dying within 3 hr. Extracts of J. curcas L., J. gossypiifolia L., J. excisa Griseb, and azadirachtin were equally bioactive; although after 3 hr, the three Jatropha species killed bugs faster. When compared with DMSO, all extract emulsions were bioactive against adult bugs. Thus, active ingredients in a new biopesticide could be sourced from the stem, root, or whole plant extracts of at least five Jatropha species.

Abstract
Plant species with allelopathic effects against weeds have emerged as a potential strategy for the development of ecologically friendly bioherbicides. In this study, the allelopathic effects of the plant species Dipteryx lacunifera Ducke, Ricinus communis L., Piper tuberculatum Jacq., and Jatropha gossypiifolia L. on the weed Bidens bipinnata L. were investigated. In vitro bioassays revealed that aqueous extracts of selected plant species were able to inhibit seed germination and seedling growth of B. bipinnata, highlighting the strongest allelopathic effect evidenced by R. communis. The phytotoxicity of the aqueous extracts was evaluated in pot experiments, which indicated that the foliar application of R. communis and P. tuberculatum extracts on B. bipinnata plants caused yellowing of leaves, affecting the chlorophyll content and reducing growth. The discrimination of the plant extracts by attenuated total reflectance Fourier transform mid-infrared (ATR FT-MIR) spectroscopy combined with principal component analysis (PCA) indicated the presence of allelochemical compounds, such as phenolics and terpenoids, which may be associated with allelopathic activity. Overall, this study provides valuable information about the substantial allelopathic inhibitory effects of the plant species R. communis and P. tuberculatum on the weed B. bipinnata, which may be used for the development of eco-friendly bioherbicides.

Abstract
Jatropha species have been shown to be an important source of secondary metabolites with different biological effects. Jatropha cinerea (Ortega) Müll. Arg and Jatropha cordata (Ortega) Müll. Arg are distributed in the Northwestern region of Mexico, are adapted to extreme weather conditions and are widely used (stems, leaves, and sap) in traditional medicine. The aim of the present study was to carry out the phytochemical characterization and the evaluation of the antioxidant activity in methanolic extracts of stems and leaves from J. cinerea and J. cordata. The compounds present in the extracts of both species were characterized by ESI-IT-MS/MS and quantified by HPLC-DAD. The results showed that the stem extracts of both species are rich in phenolic acids, while the leaf extracts are rich in flavonoids. Some of the main compounds found were gallic acid, gentisic acid, 3,4-Dihydroxybenzoic acid, vitexin, isovitexin, and catechol. Both species showed high concentrations of phenols and total flavonoids and antioxidant activity. J. cordata showed the highest antioxidant capacity and the highest concentration of phenolic compounds. Overall, both Jatropha species are a natural source of antioxidant compounds with potential biotechnological uses.

Abstract
Recent movements for the decarbonization of the electricity sector have become a priority for many countries around the world and will inevitably lead to the sharp decline of fossil-fuel-based energy. Energy from fossil fuels is to be replaced by renewable energy sources (RES), although the transition will neither be cheap nor smooth. One sustainable and environmentally friendly alternative to fossil fuels and which will take a considerable share in the increasing supply of renewable energy resources is biofuels. There are various types of biofuels used in practice; however, biodiesels represent one of the most popular and widespread ones. This paper focuses as a case study on the byproducts of Jatropha curcas, a crop and a plant that is already used for biofuel production and which is subsequently employed in electricity generation in Jatropha curcas producing regions. This paper identifies the limitations and prospects of Jatropha curcas utilization. Also, Jatropha curcas is compared to other materials suitable for biomass generation. An economic analysis for a 2 MW biofuel powerplant was conducted incorporating various market-related risks. The study shows that at current prices, net profitability can be achieved using Jatropha curcas byproducts for producing electricity.
