Phytochemical Composition of Ziziphus lotus (L.) Lam and Its Impact on the Metabolic Syndrome: A Review

The long-term pathological state known as metabolic syndrome is characterized by hypertension, insulin resistance diabetes, abdominal obesity, and hyperlipidemia. Seeking healthcare strategies with fewer side effects, such as herbal remedies, is preferable in terms of mitigating the negative consequences of synthetic medications. Ziziphus lotus (L.) (Rhamnaceae) or wild jujube, commonly known as "Sedra," is one of the best choices as it contains a variety of phytochemicals and biologically active compounds. Several flavonoids and stilbenes have been recognized as the primary bioactive components in wild jujube, including rutin, hyperin, isoquercitrin, and resveratrol. These polyphenols are pharmacologically active and have broad-spectrum beneficial effects for reducing the risk factors associated with metabolic syndrome. They exhibit antioxidant and anti-inflammatory properties, regulate lipid metabolism, and possess antiobesity, antihypertensive, and antidiabetic characteristics. However, there are certain limitations to their therapeutic application, such as low bioavailability. Various strategies have been proposed to enhance their pharmacokinetic profile and therapeutic potential for future use. The main goal of this review is to explore the underlying mechanisms related to the therapeutic effects of wild jujube and its active compounds in the treatment and prevention of metabolic syndrome.

Ethnobotanical survey of medicinal and aromatic plants used by the population of Settat Province, Morocco

To promote Morocco's medicinal and aromatic plants, an ethnobotanical study was conducted in the Settat Province, part of the Casablanca-Settat region, Morocco. The methodology employed in this study involved a direct, oral survey conducted with 30 herbalists from various villages in the Settat province, after obtaining their informed consent. Additionally, an online survey was distributed, to which 212 individuals from the local population, representing different age groups, responded. The sample size was chosen to ensure a confidence level of 88 %. The results provided a database on the modes of use, plant parts utilized, treated pathologies, and recommended dosages for 51 medicinal and aromatic plants from the Settat province and enabled us to calculate their Familiarity Index (FI). The data collected showed that the Lamiaceae, Apiaceae, and Fabaceae families are the most represented. The calculated Familiarity Index indicated that the most commonly used species were Verbena, Pimpinella anisum L., and Origanum vulgare, with Familiarity Index of 0.22, 0.22, and 0.18, respectively. The most frequently utilized plant part was the leaves, and 70.59 % of respondents preferred drying the plants before preparing them as infusions or decoctions. The results highlighted the primary ailments treated with these plants, such as diabetes, gastrointestinal disorders, cardiovascular diseases, oral conditions, cancers, insomnia, and stress. Additionally, the study referenced traditional medicinal uses from various national studies and international scientific research that validated the therapeutic properties of each plant.

Chemical composition, antioxidant, and antimicrobial properties of Mentha subtomentella: in sight in vitro and in silico analysis

Our research focused on assessing essential oils (MSEO) and aqueous extracts (MSAE) derived from M. subtomentella leaves, with a primary focus on evaluating their properties. From 1 kg of leaves, we successfully obtained 18 mL of essential oil. Upon conducting GC/MS analysis, we identified eleven compounds within the oil, collectively accounting for 100% of the constituents identified. Notably, the predominant compounds in the leaf oil were p-Menth-48) -en-3-one (50.48%), 9-Ethylbicyclo (3.3.1) nonan-9-ol (10.04%) (E)-3,3-Dimethyl-delta-1, alpha-cyclohexaneacetaldehyde (8.53%), and D-Limonene (7.22%). Furthermore, utilizing HPLC/DAD, we explored the phenolic profile of MSAE, extracted through decoction. This analysis revealed the presence of fifty-eight compounds, with five major components collectively constituting 61% of the total compounds identified, rosmarinic acid as the major one. We evaluated the antimicrobial effectiveness of the MSEO against ten different strains, observing its notable efficacy against A. Niger (MIC = 0.09%), P. digitatum (MIC = 0.5%), and G. candidum (MIC = 1%). However, the essential oil demonstrated comparatively lower efficacy against bacteria than fungi. In contrast, the MSAE did not exhibit any antimicrobial activity against the tested strains. Regarding antioxidant activity, the aqueous extract displayed a significantly higher antioxidant capacity than the essential oil, which exhibited relatively lower antioxidant activity. The IC50 values were determined to be 0.04 ± 0.01 mg/mL, 0.17 ± 0.01 mg/mL, and 13% ± 0.01% (V/V), for ascorbic acid MSAE and MSEO, respectively. We used a computational method called molecular docking to investigate how certain plant compounds affect antioxidant, antibacterial, and antifungal activities. This involved analyzing the interactions between these compounds and specific protein targets known for their roles in these activities.

Antifungal Potential of Some Herb Decoctions and Essential Oils on Candida Species

(1) Background: Candidiasis is a fungal infectious disease caused by opportunistic Candida species. The incidence of candidiasis has improved, due to prolonged antibiotic therapy and an increased number of immunocompromised patients. The purpose of this study was to evaluate if decoctions and essential oil (EO) of neem (Azadirachta indica, Meliaceae family), coptidis (Coptis chinensis, Ranunculaceae family), magnolia (Magnolia officinalis, Magnoliaceae family), scutellaria (Scutellaria barbata, Lamiaceae family), and the EO of manuka (Leptospermum scoparium, Myrtaceae family), have antifungal activity in vitro against some clinically prevalent species of Candida. (2) Methods: The antifungal activity was studied by the determination of the minimum inhibitory concentration (MIC) and minimum lethal concentration (MLC) against five Candida strains. The effect in dimorphic transition of Candida albicans was also evaluated for the two plants with higher antimicrobial behavior. (3) Results: C. chinensis decoction and EO and L. scoparium EO exhibited antifungal activity in Candida spp. In addition to the fact that both C. chinensis decoction and EO proved strong antifungal activity, L. scoparium EO also displayed a relevant inhibitory effect on the dimorphic transition. (4) Conclusions: The results provided support for the potential use of C. chinensis and L. scoparium in the treatment of infections by Candida spp.

Ethnobotanical Review and Dataset Compiling on Wild and Cultivated Plants Traditionally Used as Medicinal Remedies in Italy

Over the centuries, wild plants have constituted the main food ingredients and traditional medicine in rural communities. In the last decades, thousands of ethnobotanical studies have been conducted, with the aim of documenting the traditional knowledge on wild and cultivated plants both for food and therapeutic purposes. In the present work, 75 published papers related to Italian ethnobotanical knowledge on wild and cultivated plants traditionally used for medical purposes were analyzed and data on 1117 different species organized in the first dataset to target medicinal applications only. For each plant species, the Italian region of use, plant organs, mode of preparation, specific pathological group of application, citation index, and use index were listed. The different therapeutic applications were subdivided into nine main pathological groups according to the targeted human apparatus. Overall, the cited species with highest number of uses were related to the treatment of the digestive system and skin-ears-eyes-hair diseases, followed by diseases of the genito-urinary and respiratory systems. The 13 most relevant species were identified on the basis of their citation and use indexes. The present review on Italian medicinal flora aims to provide valuable information on wild and cultivated species, which are potential sources of plant-based therapeutic remedies, to preserve and reevaluate endangered traditional folk knowledge.

Ruta montana (L.) L.: An insight into its medicinal value, phytochemistry, biological properties, and toxicity

Ruta montana (RM) is a medicinal and aromatic plant (MAP) used in folk medicine, especially in North Africa, to treat digestive, infectious, respiratory, neurological, gynecological, and diabetic diseases. The current work aims to review the scientifically validated ethno-medicinal usage, bioactivities and phytochemistry of RM, in order to provide data support for further investigations. Data were procured from PubMed, Scopus, Google Scholar, Web of Science, ScienceDirect, and PubChem. The present study revealed that RM could be used to manage many diseases involved in public health problems, such as diabetes, hypertension, neurological disorders, infections, reproductive system disorders, and cancer. It might also replace chemical insecticides and fungicides since it exhibits antifungal, insecticidal, and larvicidal properties. RM extracts also contain mainly coumarins and alkaloids. The volatile oil of RM is characterized by an abundance of ketone compounds and 2-undecanone as major constituents. In the case of a high-dose administration, RM infusion can cause poisoning through the oral path. Thus, in-depth in vivo pharmacological studies and clinical trials are needed to transmute the traditional applications of RM into scientific-based information.
