Abstract
Scabiosa artropurperea var.maritima is a plant widely distributed in the Mediterranean region and used as a traditional medicine. The present study evaluated the biochemical composition and the potential toxicity of aqueous extract of whole Scabiosa artropurperea var.maritima through acute toxicity oral administration in male mice. Phytochemical analysis of the Scabiosa artropurperea var.maritima revealed high levels of reductor sugars and significant flavonoid and total phenol content. The aqueous extract of Scabiosa artropurperea var.maritima was daily oral administered to mice at doses of 300 (group 1), 2000 (group 2) and 4000 (group 3) mg/kg body weight per day for 14 days. We observed no significant difference in the consumption of food, body weight and relative organ weights except for an increase in the seminal vesicles weight in group 3. Hematological parameters revealed the non-adverse effects of prolonged oral consumption of Scabiosa artropurperea var.maritima except for a slight increase but significant of percentage of hematocrit in group 1 and 3 and a decrease in percentage of granulocytes in group 2. The histopathologic examination did not show any differences in vital organs. We also observed non-adverse effects on the reproductive parameters including testosterone concentration, spermatozoa motility and morphologies. Based on our findings, the aqueous extract of Scabiosa artropurperea var.maritima could be considered safe for oral medication in animals.

[PMID: 37514300 PMCID: PMC10383961 DOI: 10.3390/plants12142686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 07/04/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023]
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
Fruit of Cycas pectinata Buch.-Ham has been used as medicine by the local community in some parts of the north eastern state of India. Despite its uses for different purposes, the safety assessment study has not been conducted. Therefore, we have evaluated the acute and the sub-acute toxicity of methanolic extract of C. pectinata fruit (CPFE) in a mice model via oral route of administration. Phytochemicals analysis was carried out by liquid chromatography-mass spectroscopy (LC-MS), nuclear magnetic resonance (NMR), and Fourier-transform infrared spectroscopy (FTIR). The acute toxicity study was performed at a single dose of 1000, 3000 and 5000 mg/kg and the sub-acute toxicity study at a dose of 100, 300 and 500 mg/kg was administered daily for 28 days. The calculated Lethal dose 50 (LD50) of CPFE was found to be 4000 mg/kg. Both acute and sub-acute studies showed that 5000 mg/kg and 500 mg/kg dose was toxic to the mice. The results of acute toxicity showed CPFE could have a mild toxic effect on the kidney at a dose of 3000 and 5000 mg/kg, as some deteriorated changes in the kidney along with increase creatinine levels were observed. Acute toxicity also showed an increase in white blood cells (WBC) at a dose of 3000 mg/kg.However, sub-acute toxicity studies do not show any detrimental effects on liver, kidney and hematological parameters. Thus, it can be suggested that CPFE at a dose of 100 and 300 mg/kg would be safe for consumption. The phytochemicals analysis by LC-MS, NMR and FTIR showed the presence of 32 major chemical compounds with certain biological activity like anti-neoplastic, antioxidant, and possible modulator of steroid metabolism (cholesterol antagonist and agonist of testosterone 17β-dehydrogenase) as predicted by PASS analysis.

Nouri A, Gasmi L, Safsaf A, Harzallah D, Khennouf S, Dahamna S. Secondary metabolite contents and safety assessment study of the aqueous extract from the Algerian Echium trygorrhizum Pomel roots. JOURNAL OF ETHNOPHARMACOLOGY 2023; 301:115771. [PMID: 36206871 DOI: 10.1016/j.jep.2022.115771] [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: 12/05/2021] [Revised: 12/26/2021] [Accepted: 09/26/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Species of Echium trygorrhizum Pomel, belonging to the Boraginaceae family, grow wild in North Africa. This plant is used in traditional Algerian medicine for the treatment of Diabetes, Jaundice and Tonsillitis. AIM OF THE STUDY To our knowledge, no work has been done on the phytochemistry and biological activities of this plant. Moreover, no study has yet corroborated that the use of this plant is safe. Therefore, the present study was carried out to gather information on the various medicinal uses of this plant and to evaluate the total phenolic content and assess its safety after acute and sub-acute toxicity tests with rodents (mice and rats). MATERIAL AND METHODS An ethnopharmacological survey was carried out using a direct questionnaire. It included some questions relating to the plant. The content of polyphénols, flavonoids and tannins present in the aqueous extract was determined by colorimetric methods. In the acute toxicity tests, three groups each containing five males and five females Albino mice were formed. The control group received water, while the test groups received different doses of aqueous extract (2000 and 5000) mg/kg body weight. In the subacute toxicity study, different doses (250, 500 and 1000 mg/kg) of the aqueous extract were administered to male and female rats for 28 consecutive days. Hematological analysis, biochemical parameters estimation and histopathological examination have been determined at the end of the treatment. RESULTS Data from the ethnopharmacological survey showed that 25, 31% of people used this plant in Algeria as a traditional medicine for the treatment of Jaundice (100%), Diabetes (28, 33%) and Tonsillitis (10%). Results also revealed that aqueous extract contains high amounts of polyphenols, flavonoids and tannins. The extract did not cause any toxicity during the 14-days observation period after a single dose of 5000 mg/kg was administered to mice, with LD50 values greater than 5000 mg/kg. In a further step, the administration of the aqueous extract at all dose levels (250, 500, and 1000 mg/kg) to male and female rats during the 28-days study did not result in any deaths or behavioral changes, and there were no changes in body weight, relative organ weights, or food consumption as a result of this experiment. However, male rats showed a significant difference in relative liver weight in the high dose group (1000 mg/kg) (p < 0.05) and the satellite group (p < 0.01). In female rats, liver weight significantly increased only in the satellite group compared with the control group (p < 0.01). The results showed an increase in red blood cells (RBC), hemoglobin (Hb), and hematocrit (Hct) in the female groups. However, a clear decrease was observed in plasma ALP enzyme activities in females treated with the doses of 250 and 1000 mg/kg (p < 0.05) after the treatment periods. CONCLUSION The study indicated that the single dose of 5 g/kg AQE can be considered relatively safe as it did not cause death or any signs of toxicity in mice. Repeated oral administration of AQE at doses below 250 g/kg/day for 28 consecutive days can be considered relatively safe.

Abstract
Psoralen, a major furocoumarin component of the Fructus Psoralen (FP), in combination with ultraviolet radiation, cures abnormal pigmentation disorder. In a previous study, we synthesized a series of linear furocoumarins with different substituents, out of which 5-((diethylamino)methyl)-3-phenyl-7H-furo [3,2-g] chromen-7-one (encoded as 5D3PC) showed better pigmenting effect than others in B16 cells. In this study, we examined the mechanism underlying the melanogenic effect of 5D3PC both in vivo and in vitro. To examine the pigmentation effect, the B16 and human melanocyte cell lines, PIG1 and PIG3V melanocytes were incubated with 5D3PC. In animal experiments, C57BL/6 mice received 5% hydroquinone and were administrated with 5D3PC for 30 days. 5D3PC upregulated the melanin synthesis and tyrosinase in B16 cell, PIG1 and PIG3V. The expression level of tyrosinase (TYR), tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2), microphthalmia-associated transcription factor (MITF), cyclic adenosine monophosphate (cAMP), phosphorylation of cAMP-responsive element binding protein (p-CREB), phosphorylation of p38 mitogen-activated protein kinase (MAPK), c- phosphorylation of Jun N-terminal kinase (p-JNK) was significantly higher in 5D3PC-treated B16 cells. The oral administration of 5D3PC attenuated the depigmentation of the C57BL/6 vitiligo mice model by increasing the numbers of melanin-containing hair follicles, melanogenic protein, and melanogenesis-relative genes expression in skin tissues.

Abstract
The present study aimed to evaluate the acute and subacute toxicity profiles of Erodium guttatum extracts in mice using the methods described in the guidelines of the OECD. In the acute toxicity study, the LD50 value was greater than 2000 mg/kg. The subacute toxicity study of E. guttatum extracts showed no significant changes in body or organ weights. The administration of E. guttatum extracts to mice at a dose of 200 mg/kg led to an increase in white blood cells, platelets and hemoglobin. Moreover, the aqueous extract of E. guttatum only decreased liver aspartate aminotransferase (ASAT) levels at a dose of 200 mg/kg, and creatinine and urea levels did not show any significant alterations compared to the control group. Our results showed that the extracts of E. guttatum caused a slight increase in alanine aminotransferase (ALAT) and triglycerides. The histological study showed that mice treated with E. guttatum extracts experienced some histopathological changes in the liver, particularly with the methanolic extract, and slight changes in the kidneys and pancreas. Regarding the renal profile, no toxicity was observed. These results provide basic information on the toxicological profile of E. guttatum used in traditional medicine.

Abstract
Richardia brasiliensis, known as poaia branca, is a medicinal species widely distributed throughout Brazil and used in folk medicine. However, studies on its toxicity are practically non-existent, and little is known about its biological activity. This study aimed to investigate its phytochemical compounds, assess its in vitro and in vivo toxicities, and determine its antiproliferative activity. UHPLC-ESI-HRFTMS performed the phytochemical characterization, and the antiproliferative activity was analyzed in different tumor cell lines. In vitro toxicity was evaluated in PBMC cells, and in vivo acute and repeated dose toxicity was evaluated according to OECD guidelines. It was identified alkaloids and terpenes as significant compounds. Regarding its antiproliferative activity, the human melanoma strain decreased its viability by about 95%. In vitro toxicity showed that the extracts maintained the viability of PBMCs; however, higher concentrations were able to increase the production of dsDNA quantity. In vivo tests showed no mortality nor signs of toxicity; the alterations found in hematological and biochemical parameters are within the standards for the species. The results indicate that R. brasiliensis has a good effect against the tumor cell line; still, more studies on its toxicity at higher concentrations are needed.

Abstract
Parthenium hysterophorus L. is a poisonous Asteraceae weed. The phytochemical profile, antioxidant activity, total phenolic contents (TPC), total flavonoid contents (TFC), and cytotoxicity of Parthenium hysterophorus L. flower extract were evaluated in this study, and the toxic effects were assessed in rabbits. The HPLC-DAD system was used for phytochemical analysis. The hemolytic and DPPH assays were performed. The effects of orally administering the flower crude extract to rabbits (n = 5) at four different doses (10, 20, 40, and 80 mg/kg) for ten days on hematological and biochemical parameters were investigated. The crude extract of the flower contained phenolic compounds such as Gallic acid, Chlorogenic acid, Ellagic acid, and P Coumaric acid, which were detected at different retention times, according to the HPLC results. With a sample peak of 4667.475 %, chlorogenic acid was abundant. At concentrations of 80 µg, the methanolic extract of flowers had total phenolic contents (89.364 ± 4.715 g GAE/g) and total flavonoid contents (65.022 ± 2.694 g QE/g). In the DPPH free radical scavenging assay, 80 µg of extract had the highest cell inhibition of 76.90% with an IC50 value of 54.278 µg/µL, while in the hemolytic assay 200 µg of extract had the highest cell inhibition of 76.90% with an IC50 > 500. The biochemical and hematological parameters were altered in the flower extract-fed groups as compared to the control (p < 0.05). The toxic effects on the blood, liver, and kidneys were confirmed. The findings also confirmed the presence of phenolic and flavonoid content in the flower extract, both of which contribute to the plant’s antioxidant potential.

Abstract
The native flora of Brazil covers a large biodiversity of plants, some of which have important pharmacological properties. Ethnobotanical studies have established that the folk use of plants for hepatobiliary disorders is very common in Brazil. This review aimed to compile, describe and discuss the main native Brazilian medicinal plants used as hepatoprotective agents listed on 25 books by authors from various regions in the country. Based on the 153 species found, a comprehensive analysis of the most relevant scientific studies is presented, including Piper umbellatum, Echinodorus macrophyllus, Fevillea trilobata and Achyrocline satureioides. Some medicinal plants share both a large number of citations and scientific evidence to corroborate their hepatoprotective effects, including Solanum paniculatum, Baccharis crispa and Phyllanthus niruri, which could be of interest to develop new phytomedicines. Additionally, some active ingredients are indicated as being responsible for the liver protective effects described, particularly phenolic compounds (flavonoids, coumestans and lignans).

Abstract
The Golden trumpet Handroanthus chrysotrichus is a tree that presents beneficial health properties against various diseases. Thus, this study aims to verify the toxicity of H. chrysotrichus bark extract, observing the effects of exposure to this extract in mice. For this, mice were separated in groups: saline (sterile solution .9%); H. chrysotrichus crude extract (HCCE) 10; HCCE 50, and HCCE 100 mg. kg-1 (p.o.). We analyzed HCCE effects on acute (single exposure) and subchronic protocol (14 days exposure). After both exposures, acute, and subchronic, we collected samples from blood, brain, liver, and kidney tissues for biochemical evaluation. In addition, after subchronic exposure, we performed behavioral tests. Acute exposure caused an increase of lipid peroxidation in liver tissue. Moreover, we observed a significant carbonyl increase in liver and brain tissues from HCCE 50 mg. kg-1. Kidneys presented carbonyl increase in mice treated with the highest concentration. Besides, creatinine increased in the group of the acute exposure at HCCE 100 mg. kg-1. Total leukocyte count decreased in all concentrations tested. Sub-chronic exposure at HCCE 100 mg. kg-1 caused a decrease in the number of crossing and an increase in its self-grooming frequency in the open field test. In this exposure, the brain and liver had a significant increase in carbonyl levels in all concentrations. We concluded that H. chrysotrichus cause behavioral and biochemical alterations in mice. HCCE primary targets seem to be the liver, kidneys, and white cells.

Abstract
Sida rhombifolia (Malvaceae) is popularly used as a treatment for several pathological conditions; however, there is a lack of studies that identify its compounds and that evaluate comprehensively the safety of its consumption. Therefore, the aim of this study was to determinate the phytochemical constitution of the crude extract of Sida rhombifolia (CESR), and its safety in models of acute and repeated doses (28 days) toxicity. The tested dose for the model of acute toxicity was 2000 mg/kg doses for the repeated dose model were 150, 300 e 600 mg/kg. Hematological, biochemical, histopathological and oxidative markers were investigated. HPLC-DAD-MS analysis evidenced the presence of caffeic acid, coumarin, and rutin. In the acute toxicity model the only altered parameters were tissue ROS, and AST and BUN in serum. As for the repeated dose experiment both hematological and biochemical markers remained within the values of reference for the species. Obtained results demonstrate that the CESR did not present significant toxic effects when administrated orally to male and female rats in acute and repeated doses.

(Ericaceae) aerial parts. JOURNAL OF ETHNOPHARMACOLOGY 2021; 271:113881. [PMID: 33508369 DOI: 10.1016/j.jep.2021.113881] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 01/20/2021] [Accepted: 01/21/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Erica arborea known as Khlenj in Algeria is a small shrub belonging to Ericaceae family. E. arborea Aqueous extract (EAAE) is used in traditional medicine for anti-inflammatory, diuretic, antimicrobial, and antiulcer purposes. AIM OF THE STUDY To our knowledge, no data reveal the combination between in-vivo anti-inflammatory and toxicological studies of EAAE. For this purpose, the aim of this study is to evaluate the biological activity cited above and assess its safety. MATERIAL AND METHODS Anti-inflammatory activity was undergone using carrageenan-induced paw edema and croton oil-induced ear edema. The acute and sub-acute toxicity were conducted following the OECD guidelines 423 and 407, respectively. Phytochemical identification was carried out using HPLC-DAD-MS. Quantitative evaluation of polyphenols; flavonoids and antioxidant activity of EAAE were also determined. RESULTS Oral administration of EAAE (250 and 500 mg/kg) significantly (p < 0.05) reduced the edema induced by carrageenan. Administration of EAAE dosed at 250 and 500 mg/kg exhibited efficacy in reducing edema induced by croton oil. The acute administration of EAAE at doses of 2000 and 5000 mg/kg did not cause any mortality or adverse effects indicating that the LD50 is above 5000 mg/kg. The prolonged administration of EAAE (500 and 1000 mg/kg) showed a significant reduction in triglycerides levels in male and female rats whereas no significant changes in other biochemical and hematological parameters were observed. Histopathological damages were recorded in both liver and kidney animal's tissues of both sexes treated with medium and maximum doses of EAAE. Phytochemical characterization of EAAE revealed a high amount of phenolic compounds, HPLC-DAD-MS analysis led to the identification of chlorogenic acid and five flavonol glycosides: myricetin pentoside, quercetin-3-O-glucoside, myricetin-3-O-rhamnoside, quercetin-3-O-pentoside, and quercetin-3-O-rhamnoside. CONCLUSION In the light of the results obtained in this study, EAAE corroborates the popular use to treat the anti-inflammatory impairments. EAAE can be considered as non-toxic in acute administration and exhibited a moderate toxicity in sub-acute administration. High phenolic content and in-vitro antioxidant activity observed indicate that EAAE may reduce oxidative stress markers in-vivo.

Abstract
An efficient and reproducible protocol for in vitro propagation of Dolichandraunguis-cati has been established for the first time from nodal segments. In order to enhance survival rate under ex vitro conditions, photosynthetic potential of in vitro grown plantlets was also studied through JIP test based analysis of polyphasic OJIP chlorophyll a fluorescence OJIP transients, density of active reaction centers, light harvesting efficiency, electron transfer rate, dissipation energy, maximum quantum yield of primary PSII photochemistry and photosynthetic performance index. The best morphogenetic in term of explants response (92.2 %), shoot number (3.43 ± 0.07) and shoot length (4.7 ± 0.31 cm) was obtained on Murashige and Skoog medium supplemented with 0.5 mg l−1 BAP and 1.0 mg l−1 TDZ. The shoots exhibited high frequency rhizogenesis on half strength medium augmented with 2.0 mg l−1 IAA. In vitro plantlets developed highest rate of photosynthesis on day 18 after the initiation of rhizogenesis. High survival rate (96.16%) under ex vitro conditions was observed when in vitro plantlets having high photosynthetic efficiency (Fv/Fm > 0.75) were subjected to hardening and acclimatization process. Plantlets with reduced photosynthetic performance exhibited low survival rate under natural conditions. The developed in vitro protocol will be useful for genetic improvement and multiplication of D. unguis-cati. The results of this study also show that photosynthetic screening of in vitro developed plantlets is highly essential after the rhizogenesis process to achieve higher survival rate under field conditions.

Abstract
Citrullus lanatus (Cucurbitaceae) is conventionally used for the treatment of urinary tract infection, renal stones, hypertension, diabetes and diarrhoea. Current study evaluates acute and 28 days repeated toxicity ethanolic extract of C. lanatus seed (EECLS) in Wistar rats to measure its safety profile. The single dose (2000 mg/kg BW) of EECLS was administered while in 28 days repeated study 250, 500 and 1000 mg/kg BW were administered orally in rats. Parameters such as biochemical, haematological and histopathological were analysed in subacute toxicity study. During study, no apparent sign of toxicity, behavioural changes and mortality were detected in acutely exposed animals. In 28 days repeated toxicity study, rats did not show significant changes in behaviour, gross pathology, body weight, biochemical and haematological parameters. Abridged serum glucose and cholesterol levels during the study designate their roles in treatment of hyperglycaemic and hyperlipidaemic conditions. No significant difference was observed in histopathology of liver and kidneys of treated rats. The current investigation demonstrated that EECLS is non-toxic below 1000 mg/kg BW and provides protection to some body organs. The data propose that LD50 of EECLS was greater than 2000 mg/kg BW and the no observed adverse effect level (NOAEL) of EECLS was at the dose of 1000 mg/kg in rats. Taken together, our finding suggests that, EECLS is safe and provides some protection to body organs; also, its extract can be used for further preclinical and clinical evaluation for its therapeutic activity.

Abstract
Mesua ferrea Linn. is used traditionally in India and South East Asian countries as an antiseptic, antidote and a brain tonic. Recent pharmacological studies on the plant have highlighted M. ferrea to be a rich source of secondary metabolites, with proven therapeutic applications. Since the toxicity of a plant following repeated exposure is of higher clinical significance, the present investigation was conducted to establish the subacute toxicity profile of the ethanolic extract of Mesua ferrea flowers (MFE). The study was conducted in accordance with the OECD Guideline 407, wherein MFE was administered orally to groups of male and female rats (n = 5/group/sex) at the doses of 100, 500 and 1000 mg/kg, over a period of 28 days. Repeated administration of MFE had no adverse effect on the growth rate and hematological parameters of the animals. There were no changes in the biochemical parameters, except for a slight decrease in the CHOL (total cholesterol) levels, and an increase in the levels of AST (aspartate aminotransferase) and ALT (alanine aminotransferase), at the highest dose. The latter corroborated with the histopathological findings exhibiting mild lymphocytic infiltration and hepatocyte degeneration observed in the liver tissues of both sexes. According to the study, the no-observed-adverse-effect level (NOAEL) of M. ferrea in the 28-day repeated dose toxicity study in rats was 500 mg/kg. Though the overall effects of the extract at the highest dose did not translate into any serious complications, its effect on hepatic function needs to be established over a longer period of study.

Abstract
Arachis hypogaea L. (peanut) leaf is traditionally used for the treatment of insomnia in Asia. However, studies describing the safety and toxicity profile for this plant preparation are limited. Thus, the goal of this study was to investigate the toxicity of peanut leaf hydroalcoholic extract (PLHE) repeated treatment. The extract was administered orally (100, 300 or 1000 mg/kg) in male and female Wistar rats for 28 days (OECD guideline 407). PLHE treatment did not cause mortality or weight variation in the animals. Also, there was no alteration on locomotor activity (open field test), motor coordination (rotarod test), or anxiety behaviour (elevated plus-maze test). Male rats had a reduction in relative liver weight (100 mg/kg) and an increase in total kidney weight (1000 mg/kg), but there was no change in biochemical and haematological parameters after PLHE treatment. Free extracellular double-stranded DNA (dsDNA) levels was also evaluated, but PLHE treatment did not increase this parameter in rat organs. Also, the dose of 1000 mg/kg of PLHE significantly increased the total thiols in the liver of females compared with the control animals. Thus, PLHE did not induce toxicity after repeated exposure for 28 days in rats.

Abstract
Licorice is used as a medicinal plant, and several studies have shown that licorice has beneficial effects. The objective of this study was to evaluate the safety of nonpolar licorice extract using toxicity experiments. Nonpolar extract from the root of Glycyrrhiza uralensis (NERG) was analyzed by high-performance liquid chromatography (HPLC). Antioxidant ability was determined by method of TPC and DPPH. Blood pressure was monitored by using blood pressure meter. In the acute study, a single dose (2,000 mg/kg) was orally administered to mice. In the subchronic study, mice were treated with extract at doses (50, 100, 500, and 1,000 mg/kg) for 120 days. Significantly difference was not shown at blood pressure, hematological, and biochemical parameters, and histopathology on mice. The results suggested that at acute and subchronic toxicity, each levels of nonpolar licorice extract administration in experiments did not cause toxicity effects or death on mice.

Abstract
Background Lauric acid (LA), a common constituent of coconut oil, is used as food additives and supplements in various formulations. Despite various potential pharmacological properties, no scientific evidence on its dose-related toxicity and safety is available till date. Objective The current study was conducted to evaluate acute oral toxicity of LA on normal rats. Methods The study was conducted in accordance with the Organization for Economic Co-operation and Development guidelines (OECD 423) with slight modifications. LA was administered orally to female Sprague Dawley (SD) rats (n = 6/group) at a single dose of 300 and 2,000 mg/kg body weight, respectively, while normal control received vehicle only. Animals from all the three groups were monitored for any behavioural and toxicological changes and mortality for two weeks. Food and fluid consumption, body weight was monitored on daily basis. At the end (on day 15th) of the experimental period, blood was collected for haematological and biochemical analysis. Further, all the animals were euthanized, and internal organs were harvested for histopathological investigation using four different stainings; haematoxylin and eosin, Masson trichrome, Periodic Acid Schiff and Picro Sirius Red for gross pathology through microscopical observation. Results The study results showed no LA treatment-related mortality and morbidity at two different dosages. Daily food and water consumption, body weight, relative organ weight, haematological, and biochemical analysis were observed to be normal with no severe alterations to the internal tissues. Conclusion The current finding suggests that single oral administration of LA, even up to 2,000 mg/kg body weight, did not exhibit any signs of toxicity in SD rats; thus, it was safe to be used on disease models in animals.

Abstract
In recent years, great interest has been focused on using natural antioxidants in food products, due to studies indicating possible adverse effects that may be related to the consumption of synthetic antioxidants. A variety of plant materials are known to be natural sources of antioxidants, such as herbs, spices, seeds, fruits and vegetables. The interest in these natural components is not only due to their biological value, but also to their economic impact, as most of them may be extracted from food by-products and under-exploited plant species. This article provides an overview of current knowledge on natural antioxidants: their sources, extraction methods and stabilization processes. In addition, recent studies on their applications in the food industry are also addressed; namely, as preservatives in different food products and in active films for packaging purposes and edible coatings.

Abstract
Although the dried root of Saposhnikovia divaricata (Turcz.) Schischk. (Umbelliferae) is a popular medicinal plant in East Asia, there has been no systemic toxicological evaluation of a water extract of Saposhnikoviae Radix (SRE). In this experiment, an oral acute and 13-week subchronic toxicological evaluations of SRE (500–5,000 mg/ kg body weight) were performed in both sexes of Crl:CD(SD) rats. Based on the results from mortality, clinical signs, effects on body weight and organ weight, clinical biochemistry, hematology, urinalysis, and histopathology, significant acute, 4-week repeated dose range finding (DRF) and 13-week subchronic toxicity of SRE was not observed in either sex of rats; thus, the no observed adverse effect level (NOAEL) was 5,000 mg (kg/day). To identify anti-hyperuricemia potential of SRE, the suppressive effect of SRE was determined in mice challenged with potassium oxonate (PO; 250 mg/kg) via intraperitoneal injection for 8 days (each group; n = 7). SRE supplementation suppressed the uric acid level in urine through significant xanthine oxidase (XO) inhibitory activity. Kidney dysfunctions were observed in PO-challenged mice as evidenced by an increase in serum creatinine level. Whereas, SRE supplementation suppressed it in a dose-dependent manner. Collectively, SRE was safe up to 5,000 mg (kg/day) based on NOAEL found from acute and 13-week subchronic toxicological evaluations. SRE had anti-hyperuricemia effect and lowered the excessive level of uric acid, a potential factor for gout and kidney failure.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Buddleja cordata Humb. Bonpl. & Kunth, known by the population as Tepozán blanco, is a shrub plant used in traditional herbal medicine in Mexico for the treatment of tumors, cancer, sores, skin burns, rheumatic pains and diseases related to inflammatory processes such as arthritis; authors adjudicate this etno-medicinal effect to the presence of secondary metabolites in the plant such as verbascoside, however due to its low concentration in recent years biotechnological tools are applied as cell culture to biosynthesize these pharmacological active metabolites in greater quantities. AIM OF THE STUDY Evaluate the possible toxic effect after a daily administration of MeOH extracts from wild plant leaves (Bc-Wp), and cell culture (Bc-Cc) of B. cordata for 28 days, and after their anti-edematous and antioxidant activities in vivo, as well their effect on the cytokines profile during experimental arthritis induced by complete Freund's adjuvant. MATERIALS AND METHODS Both extracts were evaluated in CD1 male mice first in a toxicity test of repeated dose administrations (1 g/kg) for 28 days, after which pharmacological activity of both extracts was measure during experimental induced arthritis where three doses were tested, at the end of the study edema formation, body weight gain and antioxidant activity were measure in edema and ganglionic tissues. Finally, dose that exerted the best protective effect (250 mg/kg) was evaluated to quantify its effect over ganglionic tissue concentration of lymphocytes T CD4+, and cytokines (IL-1β, TNF-α and IL-10), as well histological analysis in arthritic mice. RESULTS Both extracts (Bc-Wp and Bc-Cc) did not exert lethality, however body weight gain and food in-take were lower than in healthy mice administered with vehicles, also extract-treated animals showed a decrease in serum lipid concentration and only Bc-Wp extract treated animals decrease serum alkaline phosphatase after 28 daily administration compared to healthy un-treated mice. During experimental arthritis best inhibition effect over edema development was observed in those animals administered with both extracts at dose of 250 mg/kg (Bc-Wp and Bc-Cc) on day 28, compared to CFA un-treated mice. Also both extracts reduce oxidative damage over lipids and proteins at the same dose, in both ganglionic and edema tissue, as well antioxidant enzymatic response was reduced in both tissues compared to arthritic un-treated group. In ganglionic tissue of arthritic mice, CD4+ lymphocytes concentration was reduced by Bc-Wp and Bc-Cc treatment (250 mg/kg) respectively, as well IL-1β, and TNF-α levels. Only arthritic animals treated with Bc-Cc extract at 250 mg/kg generated a significant increase of IL-10 doubling the levels compared to CFA un-treated group. Histological analysis of popliteal ganglion showed that both extracts decrease the incidence of lytic lesions, lipid inclusions and leukocyte infiltration. CONCLUSION Methanolic extracts of wild Buddleja cordata and its cell cultures did not generated lethality after a daily administration for 28 days at 1 g/kg, but it was observed that both showed a lipid-lowering effect. Also at dose of 250 mg/kg both extracts exerted anti-edematous, protection against the oxidation of lipid and proteins, regulation on antioxidant enzymatic response, down-regulation on lymphocytes CD4+ producers of IL-1β and TNF-α, an increase in IL-10 levels, which caused a decrease in leukocyte infiltration in ganglionic tissue during experimental arthritis.

Abstract
Lagenaria siceraria (Cucurbitaceae) is traditionally known to be used for the treatment of diabetes, ulcer, jaundice, cardiovascular disease, hemorrhoids, and colitis. This study involves evaluation of acute and subacute toxicity of methanolic extract of L. siceraria fruit (MELSF) in rats for assessment of its safety profile. For acute oral toxicity, single dose (2000 mg/kg body weight) of extract was administered in female Wister rats while in the subacute study the extract was given at doses of 250, 500, and 1000 mg/kg orally over 28 d in male and female rats. No evidence of toxicity was observed in animals when acutely exposed to MELSF, implying that the LD50 is higher than 2000 mg/kg body weight. Further, repeated administration of the extract for 28 d did not alter any hematological and biochemical parameters and no significant changes were observed in organ and body weight of control and treated groups. Histopathological assessment was normal in kidney and liver. Thus, the present investigation shows that MELSF, at dosage levels up to 1000 mg/kg, is nontoxic and can show protection of some body tissues when administered for 28 d and therefore can be considered safe. This study supports the application of L. siceraria in traditional medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Verbena litoralis Kunth is a native species of South America, popularly known as gervãozinho-do-campo or erva-de-pai-caetano. It is used in gastrointestinal disorders, as detoxifying the organism, antifebrile properties and amidaglitis. AIM OF THE STUDY To identify the chemical constituents of the hydroethanolic extract obtained from the aerial parts of V. litoralis and to evaluate the acute and sub-acute toxicity in male and female rats. MATERIALS AND METHODS The single dose (2000 mg/kg) of the extract was administered orally to male and female rats. In the subacute study the extract was given at doses of 100, 200 and 400 mg/kg during 28 days orally. Biochemical, hematological and histological analyzes were performed, oxidative stress markers were tested and chemical constituents were identified through UHPLC-ESI-HRMS RESULTS: Six classes of metabolites were identified: iridoids glycosides, flavonoids, phenylpropanoids-derived, phenylethanoid-derived, cinnamic acid-derived and triterpenes. In the acute treatment, the extract was classified as safe (category 5), according to the OECD guide. Our results demonstrated that subacute administration of the crude extract of V. litoralis at 400 mg/kg resulted in an increase in AST in males, whereas ALT enzyme showed a small increase in males that received 200 mg/kg and 400 mg/kg of the extract. CONCLUSIONS The extract of the aerial parts of Verbena litoralis did not present significant toxicity when administered a single dose. However, when different doses were administered for 28 days, were observed changes in hematological, biochemical and histological parameters in rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Morus nigra L. is a plant native to Asia, and well adapted to the Brazilian climate. It is popularly known as "amoreira preta", and is part of the National List of Plants of Interest to the Brazilian Unified Health System. It is used in folk medicine mainly to soften the effects of menopause, as anti-inflammatory, antidiabetic and antihypertensive. However, information on safe doses and use is still precarious. AIM OF THE STUDY To identify the chemical composition of the ethanolic extract of Morus nigra L. leaves (EEMN), as well as perform a toxicological study in male and female rats. MATERIALS AND METHODS The chemical composition of the extract was performed by HPLC/DAD. In the acute study, the dose administered was 2000 mg/kg, and signs of toxicity and mortality was observed. In the sub-acute study, the extract was administered at doses of 500, 750 and 1000 mg/kg for 28 days. Behavioral changes, object recognition test, renal and hepatic tissue assessments, biochemical and hematological parameters were determined. The extract was administered orally to male and female rats in both studies. RESULTS Quercetin and caffeic acid showed as major compounds in the extract. In the acute treatment, the extract was classified as safe (category 5), according to the protocol. In the subacute study, there was a decrease in AST in males (750 and 1000 mg/kg) and females (1000 mg/kg), reduction of total cholesterol in females (750 and 1000 mg/kg), and increase in renal and hepatic change the LPO levels. CONCLUSION The present investigation showed that EEMN did not present significant toxic effects when administered orally. Moreover, presented a potentially protective action of organs and possesses hypocholesterolemic activity, thus, it is shown as a promising natural source to be used in pharmacology.

Abstract
Olea europaea L., popularly known as olive, is a plant widely used worldwide. Its leaves, fruit and oil are extensively consumed and present important pharmacological properties. However, studies regarding the toxicity of olive leaves are still limited in the literature. Therefore, the aim of the study was to investigate acute and subacute oral toxicities of the ethanolic extract of olive leaves (EEO) in Wistar rats through histopathology and biochemical and hematological parameters. Acute toxicity was assessed using a single dose of 2000 mg/kg of EEO administered by oral gavage to male and female rats. To assess subacute toxicity, EEO was administered during 28 days at different doses (100, 200 and 400 mg/kg) to male and female rats. At the end of the experiments, the liver and kidney were removed and examined microscopically, and blood was collected for hematological and biochemical parameters. A single dose of 2000 mg/kg did not induce mortality or any signs of toxicity among the animals treated. Animals exposed to EEO during 28 days did not present sign of abnormalities. Results demonstrated that EEO did not induce toxicity after exposure to single and repeated doses. However, more studies are needed to fully understand implications for human safety.
