Cytotoxic, acute oral toxicity, genotoxic and mutagenic assessment of the essential oil from fresh leaves of Croton argyrophyllus (Kunth.). JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118206. [PMID: 38636572 DOI: 10.1016/j.jep.2024.118206] [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: 02/01/2024] [Revised: 04/12/2024] [Accepted: 04/14/2024] [Indexed: 04/20/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Croton argyrophyllus Kunth., commonly known as "marmeleiro" or "cassetinga," is widely distributed in the Brazilian Northeast region. Its leaves and flowers are used in traditional medicine as tranquilizers to treat flu and headaches. AIM OF THE STUDY This study was conducted to determine the chemical composition and toxicological safety of essential oil from C. argyrophyllus leaves using in vitro and in vivo models. MATERIALS AND METHODS The chemical composition of the essential oil was determined using a gas chromatograph coupled to a mass spectrometer. Cytotoxicity was tested in the HeLa, HT-29, and MCF-7 cell lines derived from human cells (Homo sapiens) and Vero cell lines derived from monkeys (Cercopithecus aethiops) using the MTT method. Acute toxicity, genotoxicity. Mutagenicity tests were performed in Swiss mice (Mus musculus), which were administered essential oil orally in a single dose of 2000 mg/kg by gavage. RESULTS The main components of the essential oil were p-mentha-2-en-1-ol, α-terpineol, β-caryophyllene, and β-elemene. The essential oil exhibited more than 90% cytotoxicity in all cell lines tested. No deaths or behavioral, hematological, or biochemical changes were observed in mice, revealing no acute toxicity. In genotoxic and mutagenic analyses, there was no increase in micronuclei in polychromatic erythrocytes or in the damage and index in the comet assay. CONCLUSIONS The essential oil was cytotoxic towards the tested cell lines but did not exert toxic effects or promote DNA damage when administered orally at a single dose of 2000 mg/kg in mice.

Aqueous Stem Extract, a Herbal Treatment for Benign Prostate Hyperplasia, in Male Sprague-Dawley Rats. J Toxicol 2024; 2024:7526701. [PMID: 38962425 PMCID: PMC11221977 DOI: 10.1155/2024/7526701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 02/12/2024] [Accepted: 02/23/2024] [Indexed: 07/05/2024] Open
Abstract
Croton membranaceus Mull. Arg. is a traditional medicinal plant frequently employed in Ghana for the treatment of benign prostatic hyperplasia and prostate cancer. The objective of this study was to determine the acute oral toxicity of the aqueous stem extract of Croton membranaceus (CMASE) in male Sprague-Dawley (S-D) rats. The acute toxicity of CMASE was evaluated using S-D rats randomly divided into four groups of five animals each. Three groups (low dose, median dose, and high dose) of rats received single oral doses of CMASE (1000, 2500, and 5000 mg/kg body weight, respectively) using an oral gavage. The control group was given distilled water. After 14 days of daily observations, hematological, biochemical, and histopathological analyses were conducted on the rats. From the results obtained, doses of CMASE up to 5000 mg/kg did not cause death or induce any clinical indications of toxicity during the study period. Also, the mean body weight and the hematological indices assessed were not significantly affected by the various doses of CMASE compared to the control group. However, serum uric acid and creatinine levels decreased significantly (p < 0.001) 14 days after the extract administration. Serum liver function enzyme levels, including alkaline phosphatase (ALP), alanine aminotransferases (ALT), and aspartate aminotransferases (AST), and serum proteins (total proteins and albumin) exhibited significant (p < 0.001) non dose-dependent changes (increases and decreases) in treated groups compared to the controls. Other biochemical indices, however, did not differ significantly between the treated groups and the controls. The gross pathological and histological analysis of the heart, liver, and kidney tissues did not reveal any significant changes in histoarchitecture. The oral LD50 of CMASE in rats was greater than 5000 mg/kg, indicating that the extract was relatively safe. It must, however, be used with care as a substitute for the roots.

Abstract
The aim of this study was to evaluate the antioxidant and hepatoprotective activity of Croton hypoleucus (EC). The present work reports the first pharmacological, toxicological, and antioxidant studies of EC extract on liver injury. Liver necrosis was induced by thioacetamide (TAA). Five groups were established: Croton Extract (EC), thioacetamide (TAA), Croton extract with thioacetamide (EC + TAA), vitamin E with thioacetamide (VE + TAA) and the positive control and vehicle (CT). For EC and EC + TAA, Wistar rats (n = 8) were intragastrically pre-administered for 4 days with EC (300 mg/kg.day) and on the last day, EC + TAA received a single dose of TAA (400 mg/kg). At 24 h after damage induction, animals were sacrificed. In vitro activity and gene expression of superoxide dismutase (SOD), catalase (Cat), and Nrf2 nuclear factor were measured. The results show that EC has medium antioxidant properties, with an IC50 of 0.63 mg/mL and a ferric-reducing power of 279.8 µM/mg. Additionally, EC reduced hepatic damage markers at 24 h after TAA intoxication; also, it increased SOD and Cat gene expression against TAA by controlling antioxidant defense levels. Our findings demonstrated the hepatoprotective effect of EC by reducing hepatic damage markers and controlling antioxidant defense levels. Further studies are necessary to identify the mechanism of this protection.

Abstract
Objective This study was aimed at identifying Ghanaian traditional medicines used for the management of prostate diseases and their constituents. Reviews of studies conducted on them are also presented. Methodology This was a prospective study. Traditional Medicine samples from consecutive patients with either lower urinary symptoms (LUTS) presenting at the Urology Unit of the Korle Bu Teaching Hospital (KBTH) in Accra from January 2015 to June 2016 and had a prior treatment with traditional medicines, had the samples retrieved. Additionally, all the 58 licensed pharmaceutical shops in Okaishie, a whole sale and retail depot for medicines in the main business district of Accra, were visited and traditional medicines for the management of prostate diseases acquired. The products constituent as labeled were documented and entered once on a proforma. This study was part of a study on the management of benign prostate hyperplasia at the KBTH approved by the Medical Directorate.The findings were analyzed and presented using descriptive statistics and presented as a table. Results Eleven products were identified with the main indigenous medicinal plant identified being the root extract of Croton membranaceus. This was the constituent in four products (Uro 500®, UR-Quick mixture®, Prostacure® and prostat®60). Although studies on the basic pharmacology and animal studies have confirmed its effect on the prostate, only one clinical study was identified. Conclusion Croton membranaceus was the indigenous traditional medicine identified for relieving LUTS due to prostate disease. There is the need for empirical evidence on its efficacy in treating Prostate cancer. Funding Not declared.

Abstract
Four previously undescribed diterpenoids including two crotofolanes, crotodichogamoin A and B, and two halimanes, crothalimene A and B, a new sesquiterpenoid, and fifteen previously reported compounds, including the crotofolane, crotohaumanoxide, the casbane, depressin, a further seven furanohalimane diterpenoids, three patchoulane and two further cadinane sesquiterpenoids and aleuritolic acid were isolated from the root of Croton dichogamus. Crotodichogamoin B is an important biosynthetic intermediate of the crotofolane class and this is the first report of patchoulene sesquiterpenoids from the genus. Compounds were tested at one concentration, 1 × 10-5 M, in the NCI59 cell one-dose screen but did not show significant activity snd were also evaluated for their cytotoxicity against Caco-2 cell lines using the neutral red assay. 10-epi-Maninsigin D reduced Caco-2 cell viability at 10, 30 and 100 μM, with values of decreased viability of 28%, 48% and 43% respectively. None of the other tested compounds showed significant activity.

Abstract
Benign prostatic hyperplasia (BPH) is an enlargement of the prostate. The study aimed at validating the use of freeze-dried Croton membranaceus ethanolic root extract for BPH management. Thirty-three patients were observed before and after 3-month administration of 20 mg t.i.d orally. The International Prostate Symptom Score (IPSS), and the International Index of Erectile Function (IIEF) questionnaires were used. Total/free PSA (tPSA, fPSA), renal, liver function, lipid tests, and ultrasonographic imaging were performed. Thirty (30) patients (66 ± 11 years) completed the study. IPSS results showed 37% had severe, 40% moderate, and 23% mild symptoms before; 57% and 43% had moderate and mild symptoms, respectively, after treatment. IIED of patients' results showed 30% with severe, 40% moderate, 24% mild-moderate, 3% mild, and 3% no erectile dysfunction before treatment and 20% severe, 43% moderate, and 37% mild-moderate dysfunction, after treatment. Quality of life (QoL) improved (P = 0.001). Significant but non-pathological increases in total and indirect bilirubin as well as apolipoprotein A occurred. Mean tPSA reduced from 27.9 ± 19.0 to 16.2 ± 11.8 ng/mL (P = 0.002); fPSA from 6.1 ± 4.8 to 3.9 ± 2.9 ng/mL (P = 0.045); and prostate volume from 101.8 ± 41.3 to 54.5 ± 24.8 cm3 (P = 0.023). C. membranaceus shrinks the prostate and improves QoL.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Croton membranaceus leaf extracts are used in the Bahamas to aromatize tobacco. In Nigeria it is used to improve digestion and in Ghana, the root extract is used for the treatment of benign prostatic hyperplasia (BPH). Despite claims of efficacy no data exists to support this. The aim of this study was to determine if Croton membranaceus aqueous root extract (CMARE) could attenuate the development of BPH in an animal model. MATERIALS AND METHODS Fifty (50) adult male Sprague-Dawley rats weighing 200-250g were randomly divided into 5 groups. Group 1 served as the control and received normal saline p.o. Groups 2-5 were castrated and injected with 5mg/kg b.wt. testosterone propionate subcutaneously for 28 days. Group 2 (model group) had no further treatment. Group 3 was simultaneously given 0.5mg/kg b.wt. finasteride p.o. throughout. Groups 4 and 5 received 30mg/kg b.wt. [low dose (LD)] and 300mg/kg b.wt. [high dose (HD)] CMARE, respectively, for 28 days. Rats were sacrificed at the end of the study and all prostate organs harvested. Wet weights, volumes and prostatic index (PI) were determined. Tissues were histologically examined. Serum prostate specific antigen (PSA) and dihydrotestosterone (DHT) levels were determined. RESULTS Prostate volume of the control group was 0.67±0.23cm(3). The model, finasteride, CMARE LD and HD groups had the following volumes: 0.92±0.12, 0.84±0.16, 0.79±0.16 and 0.80±0.19cm(3), respectively. Only the model group showed significant statistical differences with the control (p=0.007). PI for control, model, finasteride, LD and HD groups was as follows: 0.19±0.04, 0.30±0.04, 0.25±0.04, 0.21±0.05 and 0.22±0.05. No statistical differences between the control PI and the CMARE treated groups were observed. Histologically, the model group had massive growth of columnar stromal and epithelial cells. CMARE and finasteride attenuated this growth with a resultant thin layer of stromal and epithelial cells similar to the control. PSA levels were significantly lower in the treatment groups. CONCLUSION CMARE reduces stromal and epithelial cell growth, and subsequently shrinks enlarged prostate. This is the first scientific proof validating the anecdotal evidence of CMARE efficacy in the management of BPH.

Abstract
In this study, the acute and subchronic toxicity effect of the Syzygium aqueum leaf extract (SA) was evaluated. For the acute toxicity study, a single dose of 2000 mg/kg of the SA was given by oral-gavage to male Sprague-Dawley (SD) rats. The rats were observed for mortality and toxicity signs for 14 days. In the subchronic toxicity study the SA was administered orally at doses of 50, 100, and 200 mg/kg per day for 28 days to male SD rats. The animals were sacrificed at the end of the experiment. The parameters measured including food and water intake, body weight, absolute and relative organ weight, blood biochemical tests and histopathology observation. In both the acute and subchronic toxicity studies, SA did not show any visible signs of toxicity. There were also no significant differences between the control and SA treated rats in terms of their food and water intake, body weight, absolute and relative organ weight, biochemical parameters or gross and microscopic appearance of the organs. There were no acute or subchronic toxicity observed and our results indicate that this extract could be devoid of any toxic risk. This is the first in vivo study reported the safety and toxicity of SA.

Abstract
Croton membranaceus Müll.Arg. (Euphorbiaceae) is used for benign prostate hyperplasia (BPH) treatment. The study aimed at investigating organs that the aqueous root extracts of C. membranaceus (CMARE) target, which is absent in literature. Twenty-four male Sprague-Dawley rats (100-140 g) were randomly divided into 4 groups. Group 1, the control group received distilled water. Groups 2, 3 and 4 received 30, 150 and 300 mg kg(-1) b.wt CMARE respectively (oral gavage). Rats fed 90 days the standard chow diet ad libitum. Upon sacrifice, major organs were histologically examined and serum prostate-specific antigen (PSA) biochemically determined. Only the prostate was abnormal. Histologically, H&E staining revealed thickness and infoldings of the epithelial cells shrinking with increasing dose. The 30 mg kg(-1) group showed low columnar or flattened epithelium cells, whereas the columnar epithelium infoldings of the 150 mg kg(-1) b.wt and 300 mg kg(-1) b.wt groups were virtually nonexistent. The acini of the control, 30 mg kg(-1) b.wt group and the 150 mg kg(-1) b.wt groups showed clear pinkish secretion. However, secretion of the high-dose group appeared light pink in colour and the stroma cells appeared much darker than all the treated and control group. C. membranaceus targets the prostate with significant PSA reduction (P < 0.01).

Abstract
BACKGROUND Croton membranaceus (CM) is used for benign prostate hyperplasia treatment. OBJECTIVE Sub-chronic toxicity studies are non-existent and provided the basis for this study. MATERIALS AND METHODS 90 days oral administration of a low dose (LD) (30 mg/kg b. wt.), medium dose (MD) (150 mg/kg b. wt.), and high dose (HD) (300 mg/kg b. wt.) CM aqueous root extract to 3 groups (n=6 each) of male Sprague-Dawley rats, alongside a control group, was undertaken. Urinalysis, hepato-renal function tests, lipid profile, cardiac enzymes, and routine hematology tests were performed. RESULTS Triglyceride levels (C=1.05±0.19, LD=0.64±0.08, MD=0.55±0.04, HD=0.50±0.02 mmol/L) were significantly reduced (P<0.05). Very low density lipoprotein (C=0.48±0.09, LD=0.29±0.04, MD=0.25±0.02, HD=0.23±0.01 mmol/L) decreased significantly (P<0.05). Cardiac enzymes-creatinine kinase (C=568±172, LD=315±79, MD=441±209, HD=286±81 IU/L) decreased markedly (P<0.05) alongside lactate dehydrogenase (C=2675±875, LD=1667±1229, MD=1186±442, HD=855±239 IU/L) (P<0.05). CONCLUSION C. membranaceus aqueous root extract is non-toxic but demonstrates anti-atherogenic and anti-ischemic potentials.

Abstract
Croton antisyphiliticus is a medicinal plant widely used in the treatment of microbial infections, especially those affecting the genital tract. Crude extract, fractions and pure compound isolated from roots of this species were investigated to validate their antimicrobial activity against Escherichia coli and Staphylococcus aureus. The compound ent-kaur-16-en-18-oic acid was isolated as a major component (0.7% of crude extract), and its MIC value determined against S. aureus (ATCC 6538) was 250 μg/mL. This is the first phytochemical work on the species monitored with antimicrobial assay.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Croton crassifolius has been used to treat snake bites, stomach ache, sternalgia, joint pain, as well as pharyngitis, jaundice, and rheumatoid arthritis in traditional Chinese medicine. However, there is no scientific evidence which supports the use in the literature. AIM OF THE STUDY To investigate the anti-nociceptive and anti-inflammatory effects of ethanol extract of C. crassifolius. MATERIALS AND METHODS Anti-nociceptive actions of C. crassifolius were assessed in mice using the hot-plate test, acetic acid-induced writhing test, and formalin test. Anti-inflammatory effects of C. crassifolius were determined in three animal models: acetic acid-induced capillary permeability accentuation in mice, carrageenan-induced edema of the hind paw in rats, and cotton pellet-induced granuloma formation in rats. RESULTS Ethanol extract of C. crassifolius showed no significant anti-nociceptive activity in the hot-plate test. However, extract at dosages of 45, 90 and 180 mg/kg significantly reduced acetic acid-induced writhing by 28.89% (P<0.05), 38.37% (P<0.05), and 56.53% (P<0.001), respectively. The extract also caused marked dose-related inhibition of formalin-induced pain in the second phase (P<0.05 for 45 mg/kg, P<0.001 for 90 and 180 mg/kg extract). C. crassifolius extract at dosages of 45, 90 and 180 mg/kg significantly reduced acetic acid-induced capillary permeability accentuation in mice by 26.18% (P<0.05), 65.70% (P<0.001), and 79.19% (P<0.001), and suppressed carrageenan-induced paw edema by 21.28% (P<0.05), 30.69% (P<0.01), and 49.17% (P<0.001) at 6 h after carrageenan injection, respectively. 180 mg/kg of the extract also showed significant activity against carrageenan-induced paw edema at 4 h. At 90 and 180 mg/kg, the extract inhibited cotton pellet-induced granuloma formation in rats. CONCLUSIONS These results collectively demonstrate that the ethanol extract of C. crassifolius possesses peripheral anti-nociceptive and anti-inflammatory effects, providing evidence to rationalize the traditional use of C. crassifolius for the treatment of pain and inflammation.
