The present study evaluated the antioxidant and anti-inflammatory properties of Cleome arabica (CA) fruit extract against bisphenol A (BPA)-induced ovarian injury in female Wistar rats. The antioxidant activity was estimated by the total antioxidant capacity (TAC) and superoxide radical (NBT) content. For the in vivo analyses, 24 animals were divided into the following 4 groups: the control group; the BPA group (50 mg/kg BW BPA for 30 days); the BPA +CA group (50 mg/kg BW BPA and 50 mg/kg BW CA); and the CA group (50 mg/kg BW CA). The in vitro results demonstrated that CA exhibited strong antioxidant activity and scavenged O2•- radicals. . Pharmacokinetic properties were also explored, reflecting the physiological dynamics of the five active molecules (quercetin, catechin, kaempferol, rosmarinic acid, and naringenin).The in vivo findings revealed a significant increase in body weight associated with a significant increase in plasma C-reactive protein (CRP), proinflammatory cytokines (IL-1, IL-6, and TNF-α), and testosterone levels (p < 0.01). In addition, ovarian histological disruption was observed. However, co-administration of CA extract significantly improved ovarian histological integrity and attenuated inflammatory and androgenic disturbances. Moreover, in silico investigations showed that CA compounds interacted more strongly with the active sites of IL-1β, IL-6, or TNF-α. The best binding energy was observed between catechin (five H-bonds) and IL-1β and IL-6, at -6.0 and -6.1 kcal/mol, respectively, and between rosmarinic acid (four H-bonds) and TNF-α, at -6.4 kcal/mol. The present study supports the use of Cleome arabica in the treatment of infertility for female polycystic ovary syndrome (PCOS) patients.

Finding substantial substitution of chemical pesticides to control cockroaches, which were proved to have a link with multiple health issues, has become the major target of many researchers. In fact, subjecting this pest to the effects of toxic plants extracts is considered ideal to primarily avoid jeopardizing human health. This study is divided into two objectives. The first of which is to confirm the toxicity of the ethanoic extract from the Cleome arabica plant on two species of urban cockroaches; which are Bllattella germanica and Bllatta lateralis, while the second is to verify the effect of the attractive odor of the extract on the feeding behavior of the two already mentioned species. Therefore, the findings demonstrated that, on the one hand, the extract causes a mortality rate of 60% of B. germanica after 30 days of treatment at a high concentration of (3g/l). On the other hand, mortality rate in B. lateralis does not exceed 6.7%. Further, findings exhibited that the proportion of B. germanica attracted by the smell of the plant soaked in hexane at a specified time (15, 30 and 60 minutes) was estimated at 40%, whereas that of B. lateralis exceeded 60%. The results of this work suggest the presence of toxic substances in the studied extract which may lead to the development of bio-insecticides based on Cleome arabica to be used in the pesticide market.

The search for sustainable, cost-effective and environmentally friendly corrosion inhibitors for hydrochloric acid (HCl) solution in industrial applications has garnered increasing interest in plant extracts and their refined metabolites. In this research, Cleome arabica L. (CA) extract, found in the Algerian Sahara, was considered due to its low cost compared to other studied plants and higher content of active compounds, thereby emerging as a promising candidate and offering the potential to promote a circular economy model. This study assessed the effectiveness of CA extract as a green corrosion inhibitor for AISI 1045 carbon steel in 0.5 M HCl solution and highlighted its potential to advance the field of green corrosion inhibitors. ATR-FTIR and LC-ESI-MS/MS analyses revealed the presence of significant organic compounds, including coumaric acid (74.58%), 4-methoxybenzoic acid (12.53%), and kaempferol (8.05%), which contributed to the corrosion inhibition. The inhibitory effectiveness of the CA extract was evaluated at five concentrations, ranging from 0.125 to 1 g L-1, using weight loss measurements, potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). The highest inhibition efficiency (η = 94.45%) was observed at a CA extract concentration of 1 g L-1 after 196 hours of immersion in 0.5 M HCl. Thermodynamic analysis using the Langmuir adsorption isotherm yielded a ΔG ads value of -24.737 kJ mol-1, indicating the spontaneous adsorption of CA molecules onto the AISI 1045 surfaces, forming a protective layer, which was confirmed by SEM/EDX analysis. Density functional theory (DFT) calculations showed a significant correlation with the experimental data, confirming that CA extract is a highly efficient and environmentally friendly corrosion inhibitor.

In recent decades, the use of herbs and plants has been of great interest, as they have been the sources of natural products, commonly named as bioactive compounds. In specific, the natural compounds from the Capparaceae family which has been proved to have antioxidant, anti-inflammatory, antimicrobial and anti-carcinogenic activities, by several studies. Cleome arabica L. (CA) specie is the most used medicinal plants in Tunisia and elsewhere in North African countries for treatment of various diseases including diabetes, rheumatism, inflammation, cancer, and digestive disorders. The current work was undertaken to estimate the total phenolic, flavonoid and condensed tannin contents, to identify and quantify the polyphenolic compounds, and to evaluate the antioxidant and the anti-inflammatory proprieties of CA fruits extract against formalin induced chronic inflammation in Female Wistar rats. In fact, the antioxidant activity was tested by Diphenyl-1-Picrylhydrazyl free radical scavenging (DPPH), Ferric reducing antioxidant power (FRAP) and Nitric Oxide radical (NO·). Anti-inflammatory effect of fruits extract was examined using formalin (2%) induced paw edema in rats. Molecular docking tools were used to investigate the interaction of some compounds from CA fruits extract with the cyclooxygenase-2 (COX-2) target protein. Our results showed that, the total phenolic, flavonoid and tannins contents, which were assessed by the Folin-Ciocalteu, Quercetin, and Catechin methods, respectively, were 230.22 mg gallic acid equivalent/g dry weight (mg GAE/g DW), 55.08 mg quercetin equivalent/g dry weight (QE/g DW) and 15.17 mg catechin equivalents/g dry weight (CatE/g DW), respectively. HPLC analysis revealed the presence of five polyphenolic compounds whose catechin was found to be the most abundant compounds. The antioxidant activity of extract was quantified by DPPH, FRAP and NO· tests and IC50 reached the values of 3.346 mg/mL, 2.306 and 0.023 mg/mL, respectively. Cleome fruits ameliorated the histological integrity of the skin and alleviated the disruptions in hematological parameters (WBC, LYM, RBC, and HGB), inflammatory cytokines (IL-1β, IL-6, TNF-α), C-reactive protein, and some oxidative stress markers (TBARS (−49%) and AOPP (−42%) levels, SOD (+33%) and GPx (+75%) activities, and GSH (+49%) content) induced by formalin injection. Moreover, the in-silico investigation had shown that CA fruits extract compounds have a stronger interaction with COX-2 active site, more than the reference drug “indomethacin” (two H-bonds). Our research gives pharmacological backing to the healthcare utilization of Cleome plant in the treatment of inflammatory diseases and oxidative harm.

ABSTRACT This study attempted to optimize the extraction conditions (liquid‒solid ratio, temperature and time) of phenolic yield from Cleome (Cleome arabica L.) fruits extract by the surface response methodology “Box‒Behnken plan” to identify and quantify polyphenolic compounds and test their antioxidant activity. A molecular docking method was developed to clarify the anti-apoptotic effects of bioactive molecules of cleome fruits. Optimal conditions were found at a ratio of 8 ml/g, 4°C and 2 h when the maximum yield was 27.24%. The total phenolic and flavonoid content assessed by the Folin-Ciocalteu and Quercetin methods were 195.20 mg gallic acid equivalent/g dry weight (mg GAE/g DW) and 51.20 mg quercetin equivalent/g dry plant weight (mg QE/g DW), respectively. HPLC and FT-IR protocols revealed the presence of five polyphenolic compounds of which catechin was found to be the most abundant. The antioxidant activity of the extract was quantified by DPPH and FRAP tests, and the IC50 values reached 6.125 mg/ml and 2.9 mg/ml, respectively. In silico analysis confirmed the beneficial effects of phenolic compounds. The results revealed significant antioxidant and antiapoptotic activities of phenolic compounds of cleome fruits and may be useful in the pharmaceutical and food industries with appreciable human health-promoting properties.

In this present study, the toxicity of Cleome arabica L. (Capparidaceae) seed oils was tested on L5 larvae of Schistocerca gregaria, Forsk. (Orthoptera-Acrididae). The forced administration of 60 ?L/individual of this vegetable oil leads to the death of all the treated larvae either before or after a few days of exuviation (imaginal moult). Signs of intoxication were observed a few hours after treatment, i.e. movement disorders, diarrhoea, inability to take food and weight loss. Male L5 larvae seem more sensitive than female L5; the mortality rates being around 90.91% and 36.36% respectively after 16 days. The TL50 recorded in treated L5 larvae is around 11 days.

ABSTRACT The pivotal Cleome arabica L. species belongs to the Cleome genus with fascinating secondary metabolites consisting of main classes of phenols, flavonoids, and glucosinolate derivatives. The current study was carried out on three crude extracts of Cleome arabica L. plant of Jordanian origin. In terms of the valuable resources for natural new drug development. The phytochemical contents, antioxidants, and antibacterial activities, in addition to the oil composition of this species were identified. Forty-six compounds representing 96.98% of the total composition were detected from the essential oil obtained by hydrodistillation (0.06%). The oil composition was dominated by nitrogen-sulfur-containing compounds (35.66%), esters (19.64%), and oxygenated sesquiterpenes (11.92%). Butanol extract had significantly the best scavenging activities of DPPH (P < .0001), ABTS (P < .0001), and hydroxyl radicals (P < .0001) while the Aq.MeOH extract exhibits the highest flavonoid content (173.5 ± 0.002 mg Quercetin/g dry extract) and had significantly the most ferrous chelating effect (P = .0011). Also, most of the tested extracts showed antibacterial activities against bacterial strains. Our findings exhibited that the Cleome arabica L. plant from Jordan origin might be a good candidate as potential biologically compounds that could be used as a source of natural antioxidants and antibacterial agents.

The use of pesticides is becoming an indispensable technique in most agricultural practices, regardless of the level of development of the country. Currently, the pesticides used are often less toxic and more specific and are based on insect physiology. Recent studies indicate that pesticide intoxication induces oxidative stress. This work aims to study the neurobehavioral consequences of the administration of two insecticides currently widely used in agriculture: spirotetramat (an inhibitor of lipid synthesis in insects) and the ethanolic extract of Citrullus colocynthis (a plant endemic to the Algerian Sahara) and the ethanolic extract of Cleome arabica (Capparidaceae) The different behavioral tests (elevated cross maze, open fields and forced swimming) show that the have a significant impact on the degree of anxiety of rodents.These products significantly influence the biochemical parameters (blood sugar, cholesterol, triglycerides, urea, creatinine), the hormone Adreno CorticoTropic Hormone, acetylcholine esterase,

The aim of the study was to assess the effect of Cleome arabica on lipid metabolism. Cleome arabica (L.) is a medicinal plant used traditionally by the population of North Africa for managing diabetes mellitus. This study was designed to evaluate the antidyslipidemic and antiatherogenic capacities of Cleome arabica (L.) in normal and streptozotocin(STZ)-induced diabetic rats. The hypolipidemic, antihyperglycemic and antiatherogenic effects of oral administration of the aqueous extract of Cleome arabica (CAAE) (100 mg/kg) were evaluated in normal and diabetic rats. In addition, the quantification of polyphenols, flavonoids and tannins as well as the antioxidant activity were performed. The results showed that the extract (CAAE) revealed an antidyslipidemic action by attenuating plasma levels of Total Cholesterol (TC), Triglycerides (TGs), Low-Density Lipoprotein cholesterol (LDL-c), Very low-density lipoprotein cholesterol (VLDL-c) and glucose. Additionally, CAAE exhibited a potent antiatherogenic activity by reducing Atherogenic Coefficient (AC), Castelli's Risk index-I (cri-I), and Castelli's Risk Index-II (CRI-II). Furthermore, the findings indicated that CAAE is abundant with polyphenols, flavonoids and tannins, and exhibited an important antioxidant capacity. The study demonstrates that aqueous Cleome arabica extract was able to ameliorate lipid abnormalities associated with diabetes mellitus. This pharmacological activity might be due to the antioxidant capacities of phytochemical compounds.

Leaves of Cleome amblyocarpa Barr. And Murb. And Cleome arabica L.: Assessment of nutritional composition and chemical profile (LC-ESI-MS/MS), anti-inflammatory and analgesic effects of their extracts

Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 plants used for the treatment of toxicity were screened for their protective effects. Traditional medicinal are globally used and have rapidly grown in economic importance. Intrinsically active compounds are well-known for their antioxidant, anti-tumor, anti-viral, and anti-inflammatory activities. The study was conducted to investigate the effects of the ethanolic extract of C. arabica leaves on sexual behavior in Wistar rats. C. arabica, a medicinal plant with a foul odor, toxic, and has hallucinogenic effects. The experimental study was carried out on white rats (male and female) of the Wistar strain from the Pasteur Institute of Algiers (Kouba, Algeria), weighing between 150 and 200g sexually naive. The animals were raised in polyethylene cages and divided into two groups (n = 10 rats/group), which received a saline solution (male and female control group), 0.20µg/ml of the ethanolic extract of C.arabica leaves for seven days orally (male and female treated group). The sexual behavior test was performed according to three types of crossing. The results of the treated groups showed a significant increase in mating frequency compared to the control group. Overall, the results showed that C. arabica significantly affects sexual behavior. The ethanolic extract of C. arabica increased sexual behavior and orientation activity performance recorded in the treated animals. Thus, this study found that C. arabica has a significant effect on the rats' sexual behavior.

The study aimed to assess the antihyperglycemic effect of Cleome arabica. Cleome arabica L. or spider flower belongs to the Capparidaceae family and it is used for treating inflammation and diabetes mellitus in traditional medicine. This study aimed to evaluate the antihyperglycemic activity and acute toxicity of the aqueous extract of Cleome arabica L (CAAE). The acute toxicity of CAAE was evaluated at doses of 500, 1000, or 2000 mg/kg. Parallelly, body weight, signs of toxicity, and/or mortality were observed for 14 days. The effect of oral administration of Cleome arabica aqueous extract (CAAE) at a dose of 100 mg/kg on glycemia was performed in normal and diabetic rats. Additionally, histopathological structure of the liver, phytochemical screening and in vitro antioxidant activity were studied. The acute toxicity test revealed that all treated rats survived, and no change in body weight was observed. The results demonstrated that CAAE exhibited a significant antihyperglycemic effect in diabetic rats. Furthermore, the plant extract ameliorated the liver histology in diabetic rats with a concomitant antioxidant activity. This study shows that Cleome arabica is partly safe, and its LD50 seems to be greater than 5000 mg/kg. Cleome Arabica has a favorable effect against diabetes, which could be due to the presence of numerous secondary metabolites and by the protection of hepatocytes.

The inclination toward natural products have led the onset for the discovery of new bioactive metabolites that could be targeted for specific therapeutic or agronomic applications. This study aimed to isolate bioactive compounds from Cleome arabica L., and subsequently determine the unexplored mechanism of action of the newly identified compounds on Lactuca sativa L. Chemical investigation of the ethyl acetate fraction of methanolic silique extract of C. arabica afforded seven secondary metabolites belonging to different classes such as flavonoids, triterpene, and a new thiohydroximate derivative, named cleomside A. Among phytotoxic assays, the growth of lettuce was totally inhibited by cleomside A compared to the other identified compounds. This effect was associated with the increased levels of electrolyte leakage, malondialdehyde, and hydrogen peroxide indicating disruption of membrane integrity and induction of oxidative stress. Activities of the antioxidant enzymes SOD, CAT, and APX were also elevated, thereby demonstrating the enhanced generation of reactive oxygen species upon identified allelochemical exposure. Thus, the changes caused by cleomside A described herein can contribute to better understanding the allelochemical actions of thiohydroximate and the potential use of these substances in the production of natural herbicides compared to the other identified flavonoids and triterpene.

This study aims to phytochemical study, antiradical scavenging and antibacterial Activity of the extracts of Cleome arabica L. from the region of Oued Souf (East South Algerian). The crud extracts two methods obtained methanolic were maceration (EM) and ultra-sound (EU). The yields were: 8.95% and 9.60%, respectively. The quantitative estimation of total polyphenols is 11.57 mg EAG/g Ex (EM) and 13.46 mg EAG/g Ex (EU). The flavonoids contents in (EM) and (EU) are respectively 5.48 and 6.19 mg EQu/g Ex. the anti-free radical activity in the extracts at (concentration 0.1mg/ml) showed a great capacity to scavenge of the DPPH• radical and the percentage of inhibition was 41% in (EM) and 60.67 % in (EU). The results of the antibacterial activity of two bacterial strains: Escherichia coli and Staphylococcus aureus, revealed that Cleome arabica L. has a significant effect on the two strains with inhibition zones variable from 0 to 12 mm for Escherichia coli and 0 to 13 mm for Staphylococcus aureus.

In this study a polyphenolic extract from Cleome arabica leaves (CALE) was investigated for its antioxidant activity in vitro using DPPH•, metal chelating and reducing power methods and for its protective effects against AraC-induced hematological toxicity in vivo using Balb C mice. Results indicated that CALE exhibited a strong and dose-dependent scavenging activity against the DPPH• free radical (IC50 = 4.88 μg/ml) and a high reducing power activity (EC50 = 4.85 μg/ml). Furthermore, it showed a good chelating effects against ferrous ions (IC50 = 377.75 μg/ml). The analysis of blood showed that subcutaneous injection of AraC (50 mg/kg) to mice during three consecutive days caused a significant myelosupression (P &lt; 0.05). The combination of CALE and AraC protected blood cells from a veritable toxicity. Where, the number of the red cells, the amount of hemoglobin and the percentage of the hematocrite were significantly high. On the other hand, AraC cause an elevation of body temperature (39 °C) in mice. However, the temperature of the group treated with CALE and AraC remained normal and did not exceed 37.5 °C. The observed biological effects of CALE, in vitro as well as in vivo, could be due to the high polyphenol and flavonoid contents. In addition, the antioxidant activity of CALE suggested to be responsible for its hematoprotective effect.

The aim of this study was to evaluate the antioxidant capacities ofCleome arabicaleaves’ extract collected on two seasons in the town of Laghouat steppe region of Algeria. Five common tests for measuring antioxidant capacities were used to compare with three standard antioxidants: measurement of free radical scavenging activity with 1,1-diphenyl-2-picrylhydrazyl radical (DPPH·) and 2,2ʹ- azinobis(3-ethylbenzo-thiazo-line-6-sulfonate) (ABTS·+) radical cation, measurement of total antioxidant capacities with phosphomolybdenum, ferric reducing, and cupric reducing methods. The amount of the phenolic compounds was carried out by the quantification of total phenolic, total flavonoid, and condensed tannin contents in three organic solvents with varying polarities. The results show that the ethyl acetate is the best extractor solvent of flavonoids, while petroleum ether has the ability to extract more of terpenes. The values of quantification ranged from 0.341 to 0.751 mg of gallic acid equivalent/g of dry matter, from 0.172 to 0.682 mg of quercetin equivalent/g of dry matter and from 0.172 to 0.332 mg of catechin equivalent/g of dry matter for the total phenolic, flavonoids, and the condensed tannins, respectively. All the extract shows strong antioxidant activity, whose best are found in the ABTS and DPPH assay with IC50 values of 0.01 and 0.017 mg/ml, respectively, in a different season. These results suggest that the level of antioxidant activity in this plant varies to a great extent. They also suggest that phenolics in this plant provide substantial antioxidant activity. Upon achievement of this survey, an extra benefit of this medicinal plant may be found.
