Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Azadirachta indica A. Juss (Meliaceae), popularly known as "neem", is used for the treatment of rheumatism, cancer, ulcers, diabetes, respiratory problems, among others. This species is present on six continents and contains more than 400 bioactive compounds. Practically all parts of the plant are used in the treatment of diseases. Although it is widely used, no study has evaluated the safety of this species throughout the gestational period in Wistar rats. AIM OF THE STUDY To evaluate the genotoxicity and the effect of treatment with dried extract of leaves of Azadirachta indica on maternal toxicity and fetal development. MATERIALS AND METHODS The dried extract of leaves of A. indica was obtained by spray drying after percolation of the plant material in 30% ethanol (w/w). The total flavonoids and rutin contents of the extract were determined by spectrophotometric method and HPLC-DAD, respectively. Pregnant Wistar rats (n = 40) were divided into four groups (n = 10/group): one control and three groups treated with dried extract of leaves of A. indica at doses of 300, 600 or 1200 mg/kg. Treatments were carried out from gestational day (GD) 0-20. During gestation, clinical signs of toxicity, weight gain, feed and water consumption of the dams were evaluated. On GD 21, rats were euthanized and cardiac blood was collected. Liver, kidneys, lung, heart, uterus, ovaries and bone marrow were collected. Reproductive performance parameters, histopathological analysis, biochemistry and genotoxicity were evaluated. Fetuses were evaluated for external morphology, skeletal and visceral changes. RESULTS The total flavonoid content of the extract ranged from 2.64 to 3.01%, and the rutin content was 1.07%. There was no change in body mass gain, food and water consumption between the evaluated groups. There was also no difference between the groups in terms of biochemical parameters, reproductive performance, histopathological analysis of the mother's organs and genotoxicity. Supernumerary ossification sites of the sternum were observed, and other skeletal and visceral alterations were not significant. CONCLUSIONS The treatment did not induce maternal toxicity, it was neither embryotoxic nor fetotoxic. The extract was not potentially genotoxic, and at a dose of 1200 mg/kg, it caused changes in the ossification of the sternum.

Abstract
The disposal of industrial effluents strongly influences low-order streams, which makes them fragile ecosystems that can be impacted by contamination. In central Brazil, the Extrema River spring targets the dumping of pharmaceutical products from the surrounding industries. So, this work aimed to investigate the presence of antibiotics in Extrema River spring samples and the isolation of Staphylococcus aureus, a potential multidrug-resistant bacteria, verifying the antimicrobial resistance profile of these isolates. Three campaigns were carried out in different locals (P1-P3) between October and December 2021, in the dry and rainy seasons. The high-performance liquid chromatography-tandem mass spectrometry (LCMS) approach indicated the presence of sulfamethoxazole (≥ 1 ng/L), metronidazole (< 0.5 ng/L), and chloramphenicol (< 5 ng/L) in the water samples in November (rainy season). S. aureus was isolated in P1 (n = 128), P2 (n = 168), and P3 (n = 36), with greater resistance to trimethoprim-sulfamethoxazole (90%), clindamycin (70%), and gentamicin (60%). The presence of antibiotics in the Extrema River spring may cause S. aureus antibiotic resistance development. The presence of antibiotics and the high percentage of isolated multidrug-resistant S. aureus in the Extrema River spring cause concern and indicate the clandestine dumping of effluents from nearby pharmaceutical industries. Since preserving the springs of low-order streams is important for the environment and public health, we encourage monitoring the wastewater from Extrema River's nearby pharmaceutical industries and preserving the spring of this river.

Abstract
Momordica charantia L. (Cucurbitaceae), popularly known as "bitter melon" or "bitter gourd," is a climbing plant well-adapted to tropical countries. This plant is used traditionally to treat several conditions including diabetes mellitus, inflammation, liver dysfunctions, and cancer. Given the widespread ethnopharmacological use, this study aimed to examine the cytogenetic, maternal, and developmental toxicity attributed to exposure to dry extract of M. charantia leaves using Allium cepa and Wistar rats as test models. First, phytochemical characterization of the dry extract by high performance liquid chromatography (HPLC) analyses was performed. Then, Allium cepa roots were exposed to three different concentrations of the dry extract (0.25, 0.5, or 1 mg/ml) to determine the mitotic index, frequency of chromosomal aberrations, and nuclear abnormalities. In addition, pregnant Wistar rats were administered either 500; 1,000 or 2,000 mg/kg dry extract during the gestational period (GD) days 6-15, and subsequently possible toxic effect on the dams and fetuses were recorded. HPLC analyses confirmed rutin as the main secondary metabolite present in the dry extract. In the Allium cepa test, the dry extract was cytotoxic. In Wistar rats, dry extract administration reduced water and feed intake and mean body mass gain, indicating maternal toxicity during the organogenesis period. However, the dry extract did not markedly affect reproductive outcome parameters evaluated. Regarding developmental toxicity assessment, the dry extract treatment did not significantly alter number of skeletal malformations in the offspring. Data demonstrated that the dry extract of M. charantia leaves presents cytotoxicity and low maternal toxicity, indicating indiscriminate use needs to be avoided.

Abstract
Resumo Antioxidantes são substâncias naturais ou sintéticas que facilitam o retardo da oxidação por um ou mais mecanismos, como sequestrar radicais livres, inibir a peroxidação lipídica e complexar com metais, inibindo a destruição tecidual via oxidação. Antioxidantes são comumente usados na alimentação animal e na indústria alimentícia para prevenir a oxidação de produtos de origem animal. Além disso, os oxidantes naturais estão sendo cada vez mais aplicados na reprodução animal, principalmente na preservação do sêmen. Nesse contexto, este trabalho teve como objetivo revisar a aplicação de antioxidantes naturais na reprodução animal. Observamos que os antioxidantes naturais foram geralmente adquiridos comercialmente (80,4%) e utilizados principalmente no resfriamento/congelamento de sêmen (72%) com resultados promissores (90%) em Sus scrofa (javali), Capra aegagrus hircus (cabra), Gallus gallus domesticus (galo) e Ovis aries (carneiro). No entanto, mais estudos devem ser realizados para ajudar a regular a dosagem de antioxidantes naturais para sua aplicação.

Abstract
Abstract Antioxidants are natural or synthetic substances that delay oxidation through one or more mechanisms, such as scavenging free radicals, inhibiting lipid peroxidation, and complexing with metals, inhibiting tissue destruction via oxidation. Antioxidants are commonly used in animal feed and the food industry to prevent the oxidation of animal-origin products. Moreover, natural oxidants are used increasingly in animal reproduction, especially for semen preservation. In this context, this study aimed to review the applications of natural antioxidants in animal reproduction. We observed that the bulk of the natural antioxidants, approximately 80.4%, were commercially acquired and used mainly for semen cooling/freezing (72%) with promising results (90%) in Sus scrofa (boar), Capra aegagrus hircus (goat), Gallus gallus domesticus (rooster), and Ovis aries (ram). However, further studies are needed to help determine the appropriate dosage of natural antioxidants for applications.

Abstract
Prostatic cancer (PC) stands out in terms of its occurrence, pathophysiology, and unfavorable prognostics in humans and dogs. Natural drugs bear an integrative potential for conventional antineoplastic treatments. In this context, the bioproducts of Synadenium grantii have been empirically used in different parts of Brazil for the integrative treatment of prostate cancer in humans. However, there is no availability of scientific evidence of the antitumor effects of S. grantii. Therefore, this study aimed to investigate the bioactive compounds in the latex of S. grantii using the high-resolution mass spectrophotometry (HRMS) and to evaluate its cytotoxic effects on primary canine PC cell cultures. Four fragments of phorbol ester were identified as potential bioactive compounds using the HRMS. With the help of an MTT ([3-(4,5-dimethyldiazol-2-yl)-2,5 diphenyltetrazolium bromide]) assay, two canine prostatic carcinoma cell lines (PC 1 and PC2) showed a decrease in the tumor cell count, with an Inhibitory concentration 50 (IC50)of 0.8469 and 0.6068 mg/ml, respectively, for PC1 and PC2. In conclusion, the latex of S. grantii contains phorbol esters in its composition, and its aqueous solution has a cytotoxic effect on canine metastatic PC cells in vitro.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Justicia pectoralis Jacq. (Acanthaceae), popularly known as tilo, chambá and anador, is widely used in folk medicine in Latin American countries as a sedative, anti-anxiety, reducing menopause symptoms and in the treatment of pathologies of the respiratory tract. Although J. pectoralis is widely used by the female population, there are no studies on the safety of using this species during pregnancy. AIM OF THIS STUDY To evaluate the effects of prenatal treatment with dry extract from the aerial parts of J. pectoralis on maternal and developmental toxicity in Wistar rats. MATERIAL AND METHODS Pregnant Wistar rats (n = 10/group) were treated from gestational day (GD) 0-20 with the vehicle (control group) or with the dry extract of J. pectoralis at doses of 300, 600 or 1200 mg/kg. During pregnancy, clinical signs of toxicity, maternal weight, feed and water intake were evaluated. On GD 21, rats were anesthetized and intracardiac blood was collected to evaluate biochemical parameters. During cesarean section, reproductive performance parameters were recorded. The liver, kidneys, uterus and ovaries were removed for histopathological analysis. Fetuses were examined for possible malformations and/or skeletal and visceral variations. RESULTS Treatment with dry extract of J. pectoralis did not alter weight gain, feed intake or biochemical and maternal reproductive performance parameters There were also no significant histopathological changes in the maternal organs, as well as external, skeletal and visceral malformations in the fetuses. CONCLUSION Oral administration of J. pectoralis dry extract during pregnancy did not induce maternal toxicity or embryotoxic and teratogenic effects.

Abstract
Abstract Justicia pectoralis (Acanthaceae) is employed in folk medicine for its analgesic, anti-inflammatory and sedative effects and to treat respiratory diseases. It is known for properties of its coumarins, 1,2-benzopyrone and umbelliferone. A green, simple, fast, and inexpensive ultrasound-assisted extractive (UAE) method for extracting umbelliferone and 1,2-benzopyrone from Justicia pectoralis was optimized. Additionally, a HPLC analytical method was developed and validated for the simultaneous determination of both coumarins. The Box-Behnken design and response surface methodology were used to evaluate the UAE process. Ethanol concentration, extraction time, plant-to-solvent ratio were the independent variables studied and the coumarin content was the dependent one. The HPLC-UV/VIS method was validated in terms of recovery, linearity, accuracy, precision and robustness, proving to be valuable for the quality control of Justicia pectoralis extract and in the development of its herbal products. Results show that the optimal UAE conditions were: ethanol concentration of 15% (w/w), extraction time of 34 min and plant-to-solvent ratio of 0.1 g/mL. The predicted values of coumarin contents (22.16 µg/mL - umbelliferone and 163.86 µg/mL - benzopyrone) were determined under the optimal UAE conditions and proved that UAE is an efficient and eco-friendly extractive process for the production of aerial part extracts from Justicia pectoralis.

Abstract
Azadirachta indica A. Juss., also known as neem, is a Meliaceae family tree from India. It is globally known for the insecticidal properties of its limonoid tetranortriterpenoid derivatives, such as azadirachtin. This work aimed to optimize the azadirachtin ultrasound-assisted extraction (UAE) and validate the HPLC-PDA analytical method for the measurement of this marker in neem dried fruit extracts. Box-Behnken design and response surface methodology (RSM) were used to investigate the effect of process variables on the UAE. Three independent variables, including ethanol concentration (%, w/w), temperature (°C), and material-to-solvent ratio (gmL(-1)), were studied. The azadirachtin content (µgmL(-1)), i.e., dependent variable, was quantified by the HPLC-PDA analytical method. Isocratic reversed-phase chromatography was performed using acetonitrile/water (40:60), a flow of 1.0mLmin(-1), detection at 214nm, and C18 column (250×4.6mm(2), 5µm). The primary validation parameters were determined according to ICH guidelines and Brazilian legislation. The results demonstrated that the optimal UAE condition was obtained with ethanol concentration range of 75-80% (w/w), temperature of 30°C, and material-to-solvent ratio of 0.55gmL(-1). The HPLC-PDA analytical method proved to be simple, selective, linear, precise, accurate and robust. The experimental values of azadirachtin content under optimal UAE conditions were in good agreement with the RSM predicted values and were superior to the azadirachtin content of percolated extract. Such findings suggest that UAE is a more efficient extractive process in addition to being simple, fast, and inexpensive.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Medicinal applications of Pimenta pseudocaryophyllus infusion as a diuretic and aphrodisiac agent as well as tranquilizer in the form of tea for the treatment of emotional tension in Brazilian folk medicine has been in practice since time immemorial. Despite its popular therapeutic acceptance and claims, there are scanty scientific reports to corroborate its central biological activities. AIM To characterize anxiolytic-like effect of the dichloromethane fraction (DF) obtained from ethanolic leaf extract of the Pimenta pseudocaryophyllus and identify mechanisms of action involved while seeking to support its popular use as a soothing agent. MATERIAL AND METHODS Mice (25-35 g) were treated orally with DF obtained from ethanolic leaf extract of Pimenta pseudocaryophyllus and were submitted to light-dark box (LDB) and elevated plus maze (EPM) tests. Different groups of mice were treated with flumazenil and NAN-190 to identify mechanisms of action involved in the anxiolytic-like effect of DF. RESULTS Treatment with DF increased number of transitions and time spent in the light compartment of the LDB while the time spent and numbers of entries in the open arm of the LCE were significantly increased. Pre-treatment of the animal with flumazenil (2 mg/kg, i.p.--competitive antagonist of benzodiazepine site of GABA(A) receptor) did not block this effect, thereby excluding participation of benzodiazepine site of the GABA(A) receptor. However, anxiolytic-like effect of DF was reversed by pre-treatment with NAN-190 (0.5 mg/kg, i.p.--an antagonist of the 5-HT(1A) receptor) thereby suggesting involvement of 5-HT(1A) receptor. The thin layer chromatography and high-performance liquid chromatography analysis indicated the predominance of (E)-methyl isoeugenol and oleanolic acid in DF. CONCLUSION These results support the popular use of Pimenta pseudocaryophyllus as a calming agent and suggest the involvement of 5-HT(1A) receptor.
