Nisbett KE, Vendruscolo LF, Koob GF. Indulging Curiosity: Preliminary Evidence of an Anxiolytic-like Effect of Castor Oil and Ricinoleic Acid. Nutrients 2024; 16:1527. [PMID: 38794765 PMCID: PMC11124509 DOI: 10.3390/nu16101527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 05/09/2024] [Accepted: 05/15/2024] [Indexed: 05/26/2024] Open
Abstract
In the process of validating the elevated zero maze, a common test of anxiety-like behavior, in our laboratory, we demonstrated an anxiolytic-like effect of castor oil and its primary component, ricinoleic acid. We tested the effects of vehicle and chlordiazepoxide in male mice in the elevated zero maze following a 30-min pretreatment time. Chlordiazepoxide is a United States Food and Drug Administration-approved drug that was previously shown to exert anxiolytic-like effects in both the elevated zero maze and elevated plus maze. Chlordiazepoxide was administered at doses of 5 or 10 mg/kg. We used 5% polyoxyl 35 castor oil (Kolliphor® EL) and saline as treatment vehicles and found that the effect of chlordiazepoxide on open zone occupancy and open zone entries was blunted when 5% Kolliphor was used as the vehicle. These tests demonstrated that chlordiazepoxide increased open zone occupancy and entries in the elevated zero maze more effectively when saline was used as the treatment vehicle and that Kolliphor dampened the anxiolytic-like effect of chlordiazepoxide when it was used as the treatment vehicle. Notably, 5% Kolliphor alone slightly increased baseline open zone occupancy and entries. Given that Kolliphor is a derivative of castor oil, we next tested the effect of 5% castor oil and 5% ricinoleic acid, which is a major component of castor oil. We found that both castor oil and ricinoleic acid increased open zone occupancy but not entries compared with saline. Altogether, our findings demonstrate that Kolliphor, castor oil, and ricinoleic acid may exert anxiolytic-like effects in male mice in the elevated zero maze. This potential anxiolytic-like effect of castor oil is consistent with its well-established beneficial effects, including anti-inflammatory, antioxidant, antifungal, and pain-relieving properties.

Shahrajabian MH, Sun W. Iranian Traditional Medicine (ITM) and Natural Remedies for Treatment of the Common Cold and Flu. Rev Recent Clin Trials 2024; 19:91-100. [PMID: 38047364 DOI: 10.2174/0115748871275500231127065053] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 10/05/2023] [Accepted: 10/12/2023] [Indexed: 12/05/2023]
Abstract
Traditional Iranian medicine is usually used for both prevention and relief of cold and flu symptoms in China, Iran, and many other Asian countries all over the world. There are 4 kinds of influenza viruses. Unlike type B, which may cause seasonal epidemics, type A viruses can cause pandemics, and influenza C may lead to mild human infection with little public health effects. A literature review was done by using multiple databases such as ISI Web of knowledge, PubMed, Science Direct and Google Scholar. The most notable antiviral medicinal plants for flu and cold are honeysuckle flowers, thyme leaf, green chiretta, andrographis, peppermint oil and leaf and calendula. The most important expectorant medicinal plants for cold and flu are snake root, tulsi, licorice root, slippery elm, clove, and sage leaf. Recommended immunostimulant medicinal plants for cold and flu are eucalyptus, Echinacea root, ginseng, garlic, slippery elm, marshmallow, Usnea lichen, Isatis root, ginger root, and myrrh resin. Iranian traditional medicine, which is one of the oldest schools of traditional medicine, is one of the main concepts of disease and health, and it can be considered as an important complementary and alternative medicine, as in some cases, modern medicine has many side effects, low efficiency, and high costs. Medicinal plants and herbs, which are included in many traditional systems, have significant and promising bioactive components in organic life.

Abstract
Introduction Psidium guajava (guava) is a fruit plant of the Myrtaceae family. Guava roots, leaves, and fruits have traditionally been used to prevent and treat various infections. In the last few decades, there has been exponential growth in herbal medicine. Therefore, the present study was conducted to determine the susceptibility and synergistic properties of the antimicrobial activity of the aqueous leaf extract of guava and other antimicrobial drugs against Escherichia coli (E. coli). Methodology A prospective observational study was conducted at the Department of Microbiology, MGM Medical College and Hospital, Navi Mumbai, India, involving 180 urine samples collected from patients who exhibited symptoms of urinary tract infection (UTI). The aim was to evaluate in vitro synergism between leaf extracts of guava and antimicrobial drugs on uropathogenic E. coli, using minimal inhibitory concentration (MIC) and the Kirby-Bauer method. The Kirby-Bauer disc diffusion method was employed to determine the synergistic activity using Muller-Hinton agar (MHA), and the zone of inhibition was measured in millimeters. Results The study found that, of the 180 urine samples collected from patients with UTI, significant growth was observed in 93 samples, with the most notable increase seen in E. coli. The antibiotics tobramycin, ofloxacin, and amikacin, each showing a sensitivity of 76% and 70% respectively, were found to be the most sensitive. Conversely, cefuroxime and cephalothin, both at 76%, were the most resistant. Furthermore, the antibiotic sensitivity pattern of E. coli without guava extract demonstrated tobramycin (TOB) at 76.66%, followed by ofloxacin (OF) and amikacin (AK) at 70% each, levofloxacin (LE) at 63.33%, nitrofurantoin (NIT) at 53.33%, trimethoprim (TR) at 43.33%, cefotaxime (CTX) at 36.66%, ceftizoxime (CZX) at 30%, norfloxacin (NR) at 26.66%, cephalothin (CEP) at 23.33%, amoxicillin-clavulanate (AMC) at 20%, and cefuroxime (CXM) at 10%. In contrast, when the antibiotic sensitivity pattern of E. coli with guava extract was examined, the highest sensitivity was noted for OF (100%), followed by LE (96.66%), TOB (93.33%), AK (90%), NIT (76.66%), AMC and TR (66.66% each), CTX (60%), CZX (53.33%), CEP (50%), NX (43.33%), and CXM (26.66%). Therefore, Psidium guajava (guava) extract exhibited a synergistic effect when combined with antibiotics, most notably with ofloxacin. Conclusion The study revealed that the highest synergistic activity of guava plant leaf extract was with the antibiotic ofloxacin. This finding indicates that guava extract enhances the effectiveness of commonly used antibiotics for treating UTI, an effect mainly attributed to the flavonoid compounds and their derivatives in the guava leaf extract, which inhibit bacterial growth. This study demonstrated the antibacterial properties of guava, suggesting that combining antibiotics with guava extract can help delay the emergence of bacterial resistance.

Abstract
The number of cancer cases will reach 24 million in 2040, according to the International Agency for Research on Cancer. Current treatments for cancer are not effective and selective for most patients; for this reason, new anticancer drugs need to be developed and researched enough. There are potentially useful drugs for cancer isolated from plants that are being used in the clinic. Available information about phytochemistry, traditional uses, in vitro and in vivo experiments with plants, and pure compounds isolated from the Euphorbiaceae family indicates that this family of plants has the potential to develop anticancer drugs. This review examines selected species from the Euphorbiaceae family and their bioactive compounds that could have potential against different types of cancer cells. It reviews the activity of crude extracts, isolated compounds, and nanoparticles and the potential underlying mechanisms of action.

Abstract
Ricinus communis L. is a medicinal plant that displays valuable pharmacological properties, including antioxidant, antimicrobial, analgesic, antibacterial, antiviral and anti-inflammatory properties. This study targeted to isolate and identify some constituents of R. communis leaves using ultra-performance liquid chromatography coupled with mass spectroscopy (UPLC-MS/MS) and different chromatographic techniques. In vitro anti-MERS and anti-SARS-CoV-2 activity for different fractions and for two pure isolated compounds, lupeol (RS) and ricinine (RS1) were evaluated using a plaque reduction assay with three different mechanisms and IC50 based on their cytotoxic concentration (CC50) from an MTT assay using Vero E6 cell line. Isolated phytoconstituents and remdesivir are assessed for in-silico anti-COVID-19 activity using molecular docking tools. The methylene chloride extract showed pronounced virucidal activity against SARS-CoV-2 (IC50 = 1.76 μg/ml). It was also shown that ricinine had superior potential activity against SARS-CoV-2, (IC50 = 2.5 μg/ml). Lupeol displayed the most potency against MERS, (IC50 = 5.28 μg/ml). Ricinine appeared to be the most biologically active compound. The study showed that R. communis and its isolated compounds have potential natural virucidal activity against SARS-COV-2; however, additional exploration is necessary and study for their in vivo activity.

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
Mesoporous silica is restricted to organic solvents or other acidic media. The application of mesoporous silica depends on the medium's chemical stability and mechanical properties. It is necessary to stabilize the mesoporous silica material under acidic conditions. The results of the nitrogen adsorption characterization show that MS-50 has a large surface area and porosity, resulting in good mesoporous silica. Using variance analysis (ANOVA) to compare the collected data, the best conditions were found at a pH of 6.32, a Cd2+ concentration of 25.30 ppm, an adsorbent dose of 0.06 g, and a time of 70.44 min. The Cd2+ adsorption experiment data best fit the Langmuir isotherm model with the maximum amount of Cd2+ that MS-50 could absorb being 103.10 mg g-1.

Abstract
Annona glabra Linn is employed in conventional medicine to treat a number of human disorders, including cancer and viruses. In the present investigation, the significant phytochemical components of Annona glabra hexane extract were identified using gas chromatography-mass spectrometry (GC-MS) analysis. Three major compounds were identified in the hexane extract: tritriacontane (30.23%), 13, 17-dimethyl-tritriacontane (22.44%), and limonene (18.97%). MTT assay was used to assess the cytotoxicity of the extract on six human cancer cell lines including liver (HepG-2), pancreas (PANC-1), lung (A-549), breast (MCF-7, HTB-22), prostate (PC-3), and colon (CACO-2, ATB-37). The extract exhibited significant cytotoxic activity against both CACO-2 and A-549 cancer cell lines (IC50 = 47 ± 0.74 μg/mL and 56.82 ± 0.92 μg/mL) in comparison with doxorubicin (IC50 = 31.91 ± 0.81 μg/mL and 23.39 ± 0.43 μg/mL) and of SI of 3.8 and 3.1, respectively. It also induced moderate-to-weak activities against the other cancerous cell lines: PC-3, PANC-1, MCF-7, and HepG-2 (IC50 = 81.86 ± 3.26, 57.34 ± 0.77, 80.31 ± 4.13, and 57.01 ± 0.85 μg/mL) in comparison to doxorubicin (IC50 = 32.9 ± 1.74, 19.07 ± 0.2, 15.48 ± 0.84 and 5.4 ± 0.22 μg/mL, respectively) and SI of 2.2, 3.1, 2.2, and 3.1, respectively. In vitro anti-HSV1 (Herpes simplex 1 virus) and HAV (Hepatitis A virus) activity was evaluated using MTT colorimetric assay with three different protocols to test protective, anti-replicative, and anti-infective antiviral activities, and three separate replications of each experiment were conducted. The plant extract showed promising protective and virucidal activity against HSV1 with no significant difference with acyclovir (79.55 ± 1.67 vs. 68.44 ± 7.62 and 70.91 ± 7.02 vs. 83.76 ± 5.67), while it showed mild protective antiviral activity against HAV (48.08 ±3.46) with no significant difference vs. acyclovir (36.89 ± 6.61). The selected main compounds were examined for their bioactivity through in silico molecular docking, which exhibited that limonene could possess the strongest antiviral properties. These findings support Annona glabra's conventional use, which is an effective source of antiviral and anticancer substances that could be used in pharmaceuticals.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 108:154534. [PMID: 36371955 DOI: 10.1016/j.phymed.2022.154534] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/24/2022] [Accepted: 11/01/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Safety and toxicity have become major challenges in the internationalization of Chinese medicine. Inspite of its wide application, security problems of Chinese medicine still occur from time to time, raising widespread concerns about its safety. Most of the studies either only partially discussed the intrinsic toxicities or extrinsic harmful residues in Chinese medicine, or briefly described detoxification and attenuation methods. It is necessary to systematically discuss Chinese medicine's extrinsic and intrinsic toxic components and corresponding toxicity detoxification or detection methods as a whole. PURPOSE This review comprehensively summarizes various toxic components in Chinese medicine from intrinsic and extrinsic. Then the corresponding methods for detoxification or detection of toxicity are highlighted. It is expected to provide a reference for safeguards for developing and using Chinese medicine. METHODS A literature search was conducted in the databases, including PubMed, Web of Science,Wan-fang database, and the China National Knowledge Infrastructure (CNKI). Keywords used were safety, toxicity, intrinsic toxicities, extrinsic harmful residues, alkaloids, terpene and macrolides, saponins, toxic proteins, toxic crystals, minerals, heavy metals, pesticides, mycotoxins, sulfur dioxide, detoxification, detection, processing (Paozhi), compatibility (Peiwu), Chinese medicine, etc., and combinations of these keywords. All selected articles were from 2006 to 2022, and each was assessed critically for our exclusion criteria. Studies describe the classification of toxic components of Chinese medicine, the toxic effects and mechanisms of Chinese medicine, and the corresponding methods for detoxification or detection of toxicity. RESULTS The toxic components of Chinese medicines can be classified as intrinsic toxicities and extrinsic harmful residues. Firstly, we summarized the intrinsic toxicities of Chinese medicine, the adverse effects and toxicity mechanisms caused by these components. Next, we focused on the detoxification or attenuation methods for intrinsic toxicities of Chinese medicine. The other main part discussed the latest progress in analytical strategies for exogenous hazardous substances, including heavy metals, pesticides, and mycotoxins. Beyond reviewing mainstream instrumental methods, we also introduced the emerging biochip, biosensor and immuno-based techniques. CONCLUSION In this review, we provide an overall assessment of the recent progress in endogenous toxins and exogenous hazardous substances concerning Chinese medicine, which is expected to render deeper insights into the safety of Chinese medicine.

Abstract
The knowledge of the plants that are used may provide insight on their properties for further exploration. This study aimed to identify and collect data about medicinal plants used in traditional medicine by the population of the provincial region of Taza, Morocco. An ethnobotanical survey was carried out among 200 informants, competent villagers, herbalists, and traditional healers from the provincial region of Taza city through direct interviews using a structured questionnaire. The survey reported 55 plant species belonging to 28 families used in the folk medicine. Informants' results showed that the most frequently used plants were Origanum compactum, Mentha pulegium, Rosmarinus officinalis L., Aloysia citrodora, Calamintha officinalis Moench, and Artemisia herba-alba Asso., with a relative frequency of citation of 76%, 72%, 60%, 42%, 40%, and 30%, respectively. Moreover, in this study, the Lamiaceae family was the most commonly reported plant family, and the leaves were the most frequently used parts of the plants; otherwise, decoction and infusion were the most used modes in the preparation of remedies from medicinal plants in the traditional medicine. The sociodemographic characteristics showed that women use medicinal plants slightly more than men, the illiterate people use the medicinal plant the most, and old people have more information about the medicinal plants than the new generations. The region of Taza of Morocco has an important floristic biodiversity of medicinal plants which are used in traditional medicine practice. This result provides a good database for pharmacological screening in the search for new plants that can contain new bioactive molecules that can be used as a bioactive ingredient of medicament or as a biological alternative in pharmacology.
