Phytochemical Analysis and Assessment of Antioxidant and Enzyme Inhibitory Activity of Alchemilla pseudocartalinica Juz.

This study aimed to evaluate and compare the antioxidant capacity and enzyme inhibitory activity of extracts, sub-extracts, and fractions prepared from the aerial parts and roots of A. pseudocartalinica. The phytochemical content of the active extracts was also analyzed. According to the results, ellagic acid (38.42 mg/g) was the major compound in the aerial part methanol extract and catechin (185.30 mg/g) in the root methanol extract. The DPPH inhibition activity of all fractions was monitored, with the most active one (Fr B) reaching an IC50 value of (4.92 ± 0.59 µg/mL). All the fractions prepared from the aerial parts' water sub-extract showed higher a-glucosidase inhibitory activity than the positive control acarbose. In the tyrosinase assay, Fr B (58.81 ± 7.50 µg/mL) exhibited the highest inhibitory actions among all fractions. The structure of the major substances of the most active fraction were elucidated as quercetin 7-O-ß-glucopyranosyl-3-O-ß-glucuronopyranoside- (1), and α-[(2-formyl-5-hydroxymethyl)pyrrol-1-yl]aspartic acid (2).

Pharmacy Students' Knowledge and Attitudes about Homeopathy: A Descriptive Survey Conducted in Turkey.

BACKGROUND: Homeopathy belongs to "Traditional and Complementary Medicine" (TCM) and is defined in the TCM regulation in Turkey as a holistic practice method that aims to improve health status with personalized medicines. The international and national literature includes a limited number of studies that examine individuals' knowledge, attitudes and behaviors toward homeopathy. Although in Turkey the Regulation on Pharmacists and Pharmacies states that the sale of homeopathic medicines is allowed only in pharmacies, no study was found that evaluated awareness about homeopathy among pharmacy students. OBJECTIVE: The present study aims to assess pharmacy students' knowledge and attitudes toward homeopathy and to identify the factors that influence them. METHODS: This descriptive study was conducted between December 1, 2021 and February 1, 2022 among the students of the Faculty of Pharmacy, Karadeniz Technical University (KTU), through a face-to-face survey. In total, 418 questionnaires suitable for data quality were included in the study. The SPSS 23.0 statistical program was used to analyze the data and the statistical significance level was taken as p < 0.05. RESULTS: It was determined that 73% of the participants had heard about TCM practices and 55% had heard of homeopathy. Students in the fifth grade (p = 0.0001) and those working in an income-generating job (p = 0.026) were found to be those most aware of homeopathy. The students of the Faculty of Pharmacy correctly knew the basic working principles of homeopathy (p = 0.002). The source from which students obtained the most information about homeopathy was undergraduate courses. 80.4% of the participants thought that homeopathy should be applied by pharmacists. 47.0% of the students wanted to learn more about homeopathy or to carry out studies in the field of homeopathy in their careers. CONCLUSION: The results of this research revealed a high awareness amongst KTU pharmacy students about the practice of homeopathy.

What Does a Community Think About Aromatherapy?

The awareness and usage of aromatherapy applications are increasing day by day in society. The current study aims to evaluate the thoughts and attitudes of individuals toward aromatherapy in Türkiye and to determine factors affecting the use of aromatherapy. This community-based descriptive study is conducted throughout Türkiye. Nine hundred eighty-five questionnaires were suitable for data quality. SPSS 23.0 statistical package program was used, and the statistical significance level was accepted as P value of less than .05. Approximately 72.4% of the participants have heard of aromatherapy. The rate of hearing about the concept of aromatherapy was found to be statistically significantly higher among women (P = .000), those residing in a province/district (P = .011), and those working in an income-generating positions (P = .003). It was determined that 58.9% of the participants used any essential oil. The 5 most commonly used essential oils are lavender, tea tree, peppermint, rose, and thyme, respectively. The rate of essential oil use in women is higher than in men (P = .000). The conditions in which essential oils are most frequently used are to provide beauty to the skin (51.7%), skin diseases (51.0%), and respiratory tract diseases (46.0%), respectively. The most common sources of information about the essential oils used by the participants are the Internet/social media (57.6%) and pharmacists (53.4%). The results of this research revealed that the awareness and use of aromatherapy practice in the community are high according to the literature. Considering the high tendency to use these products among the public, physicians, pharmacists, and nurses must provide consultancy services on the use of these products.

Immunomodulatory properties of triterpenes.

The immune system is one of the main defence mechanisms of the human body. Inadequacy of this system or immunodeficiency results in increased risk of infections and tumours, whereas over-activation of the immune system causes allergic or autoimmune disorders. A well-balanced immune system is important for protection and for alleviation of these diseases. There is a growing interest to maintain a well-balanced immune system, especially after the Covid-19 pandemic. Many biological extracts, as well as natural products, have become popular due to their wide array of immunomodulatory effects and influence on the immune system. Triterpenes, one of the secondary metabolite groups of medicinal plants, exhibit immunomodulatory properties by various mechanisms. Different triterpenes, including components of commonly consumed plants, can promote some protection and alleviation of disease symptoms linked with immune responses and thus enhance overall well-being. This review aims to highlight the efficacy of triterpenes in light of the available literature evidence regarding the immunomodulatory properties of triterpenes. We have reviewed widely investigated immunomodulatory triterpenes; oleanolic acid, glycyrrhizin, glycyrrhetinic acid, pristimerin, ursolic acid, boswellic acid, celastrol, lupeol, betulin, betulinic acid, ganoderic acid, cucumarioside, and astragalosides which have important immunoregulatory properties. In spite of many preclinical and clinical trials were conducted on triterpenes related to their immunoregulatory actions, current studies have several limitations. Therefore, especially more clinical studies with optimal design is essential.

Evaluation of Hedera species as herbal medicine raw materials.

This study aimed to evaluate the potential of Hedera colchica as an alternative to Hedera helix species for the treatment of mild inflammatory conditions of the upper respiratory tract and chronic inflammatory bronchial diseases. The H. colchica extract with the highest saponin content (C3S; 468.19 ± 16.01 mg HE/g dry weight) and the extract with the highest total phenol content (C1F; 108.60 ± 5.61 mg GAE/g dry weight). Chemical analysis and standardisation of the extract with the highest selective COX-2 inhibitory effect was performed using the LC-MS/MS technique. It was determined that the substances found in the highest ratio in the C1F extract were quinic acid (45.909 µg/g extract) and hesperidin (37.077 µg/g extract). As a result, secondary metabolites, in addition to saponins, found in Hedera species may also contribute to the extract's effectiveness, more potent extracts can be obtained compared to the total extract-containing preparations available in the market.

Assessment of physicians' knowledge, thoughts, and attitudes regarding the phytovigilance system.

BACKGROUND: In this study, physicians' awareness of phytovigilance and their knowledge of safety processes for herbal products were evaluated for the first time in Türkiye. RESEARCH DESIGN AND METHODS: A descriptive quantitative study was conducted using face-to-face interview techniques with physicians working in a training and research hospital in Türkiye. A total of 268 (35.2%) questionnaires with appropriate data quality were analyzed with IBM SPSS Statistics 23.0. The factors that had the strongest effect on phytovigilance awareness were determined by binary logistic regression analysis. Values of p < 0.05 were accepted as statistically significant. RESULTS: The survey results revealed that 45.5% of physicians were aware of the concept of phytovigilance. Physicians who knew that adverse effects were reported due to the use of herbal products, physicians who asked about the use of herbal products while taking their patients' medical history, and specialist physicians had higher awareness of the concept of phytovigilance. Only 30.2% of participants were aware that feedback on adverse reactions from herbal products was being collected and only 27.2% were aware that there was a phytovigilance contact point in the hospital. CONCLUSION: The awareness of physicians regarding phytovigilance should be increased. Physicians should ask about the use of herbal products while taking medical history, identify possible adverse effects associated with herbal products, and provide feedback.
