[PMID: 39153558 DOI: 10.1016/j.fitote.2024.106188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 08/12/2024] [Accepted: 08/14/2024] [Indexed: 08/19/2024]
Abstract
This review investigates the therapeutic effects of Ulmus species extracts, traditionally used as tea ingredients in East Asia, on bone health and inflammatory conditions. Through the analysis of 9757 studies, narrowing down to 56 pertinent ones, we evaluated the safety and efficacy of Ulmus extracts. The focus was on catechin glycosides (CG) and flavonoid glycosides (FG), key compounds identified for their potential benefits. The research highlights the extracts' role in enhancing bone mineral density (BMD) by stimulating osteoblast activity and suppressing osteoclast differentiation, suggesting a protective effect against osteoporosis. Furthermore, the extracts demonstrated significant anti-inflammatory properties by modulating inflammatory markers and pathways. The findings confirm the historical use of Ulmus extracts in East Asia for health benefits and recommend further exploration into functional foods and nutraceuticals. The review calls for more rigorous research, including clinical trials, to establish optimal use and integration into modern health solutions. It underscores the potential of Ulmus extracts in promoting bone health and managing inflammation, advocating for a bridge between traditional practices and contemporary scientific validation. In conclusion, Ulmus extracts, a material long consumed as tea ingredients in East Asia, exhibit significant potential for improving bone health and reducing inflammation. This review calls for additional research to explore their full therapeutic capabilities, emphasizing the need for optimized extraction methods and clinical trials. It reinforces the importance of bridging traditional knowledge with contemporary scientific approaches to health and dietary solutions, promoting overall wellness.

Neuroprotective effects of Tradescantia spathacea tea bioactives in Parkinson's disease: In vivo proof-of-concept. J Tradit Complement Med 2024; 14:435-445. [PMID: 39035688 PMCID: PMC11259708 DOI: 10.1016/j.jtcme.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 01/05/2024] [Accepted: 01/07/2024] [Indexed: 07/23/2024] Open
Abstract
Background and aim Tradescantia spathacea (T. spathacea) is a traditional medicinal plant from Central America and its tea, obtained by infusion, has been recognized as a functional food. The aim of this work was to investigate the effects of dry tea containing biocompounds from T. spathacea tea on motor and emotional behavior, as well as tyrosine hydroxylase (TH) and glial fibrillary acidic protein (GFAP) expression in 6-hydroxydopamine (6-OHDA)-lesioned rats. Experimental procedure Bioactives were identified by Ultra Performance Liquid Chromatography (UPLC) and an in vivo study in male Wistar rats was run as proof of concept of neuroprotective effects of DTTS. Results and conclusion We found 15 biocompounds that had not been previously reported in T. spathacea: the UPLC-QTOF-MS/MS allowed identification five phenolic acids, one coumarin, two flavonoids, one iridoid, one phenylpropanoid glycoside, and six fatty acid derivatives. The dry tea of T. spathacea (DTTS) presented significant antioxidant activity and high contents of phenolic compounds and flavonoids. Doses of 10, 30, and 100 mg/kg of DTTS were protective against dopaminergic neurodegeneration and exhibited modulatory action on the astrocyte-mediated neuroinflammatory response. Behavioral tests showed that 30 mg/kg of DTTS counteracted motor impairment, while 100 mg/kg produced an anxiolytic effect. The DTTS could be, therefore, a promising strategy for the management of Parkinson's disease.

Abstract
Diabetic retinopathy (DR) is one of the most severe complications of diabetes mellitus and potentially leads to significant visual impairment and blindness. The complex mechanisms involved in the pathological changes in DR make it challenging to achieve satisfactory outcomes with existing treatments. Diets conducive to glycemic control have been shown to improve outcomes in diabetic patients, thus positioning dietary interventions as promising avenues for DR treatment. Investigations have demonstrated that natural products (NPs) may effectively manage DR. Many types of natural compounds, including saponins, phenols, terpenoids, flavonoids, saccharides, alkaloids, and vitamins, have been shown to exert anti-inflammatory, antioxidant, anti-neovascular, and antiapoptotic effects in vivo and in vitro. Nevertheless, the clinical application of NPs still faces challenges, such as suboptimal specificity, poor bioavailability, and a risk of toxicity. Prospective clinical studies are imperative to validate the therapeutic potential of NPs in delaying or preventing DR.

Abstract
Ulmus macrocarpa Hance bark (UmHb) has been used as a traditional herbal medicine in East Asia for bone concern diseases for a long time. To find a suitable solvent, we, in this study, compared the efficacy of UmHb water extract and ethanol extract which can inhibit osteoclast differentiation. Compared with two ethanol extracts (70% and 100% respectively), hydrothermal extracts of UmHb more effectively inhibited receptor activators of nuclear factor κB ligand-induced osteoclast differentiation in murine bone marrow-derived macrophages. We identified for the first time that (2R,3R)-epicatechin-7-O-β-D-apiofuranoside (E7A) is a specific active compound in UmHb hydrothermal extracts through using LC/MS, HPLC, and NMR techniques. In addition, we confirmed through TRAP assay, pit assay, and PCR assay that E7A is a key compound in inhibiting osteoclast differentiation. The optimized condition to obtain E7A-rich UmHb extract was 100 mL/g, 90 °C, pH 5, and 97 min. At this condition, the content of E7A was 26.05 ± 0.96 mg/g extract. Based on TRAP assay, pit assay, PCR, and western blot, the optimized extract of E7A-rich UmHb demonstrated a greater inhibition of osteoclast differentiation compared to unoptimized. These results suggest that E7A would be a good candidate for the prevention and treatment of osteoporosis-related diseases.

Abstract
The phytochemical investigation of Ulmus minor subsp. minor samaras EtOAc and n-BuOH extracts is reported in this work for the first time, resulting in the isolation and characterization of twenty compounds (1: - 20: ) including one new flavan-3-ol (1: ), one new trihydroxy fatty acid (2: ), and two glycosylated flavonoids (6: - 7: ) whose NMR data are not available in the literature. Structure elucidation of the isolated compounds was obtained by 1D and 2D NMR and HRESIMS data. Prior to further pharmacological investigations, the extracts (100 - 6.25 µg/mL) and compounds 1: - 12: (50 - 5 µM) were tested for their influence on viability of a murine macrophage cell line (J774A.1). Subsequently, extracts and compounds that did not impede viability, were studied for their inhibitory effect on some mediators of inflammation in J774A.1 cells stimulated with lipopolysaccharide of Escherichia coli (LPS). The NO release and the expression of iNOS and COX-2 were then evaluated and both extracts (50 - 6.25 µg/mL) and compounds (20 - 5 µM) significantly inhibited NO release as well as iNOS and COX-2 expression in macrophages. These data highlight the anti-inflammatory properties of several isolated compounds from U. minor samaras supporting their possible alimentary use.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Prosthechea karwinskii (Mart.) J.M.H. Shaw is a Mexican orchid used in traditional medicine by some indigenous communities to treat issues related to inflammation (cough, wounds, burns, and diabetes). Pharmacological research of this orchid could validate its therapeutic uses and demonstrate its potential for treating other health conditions of high prevalence in Mexico, including those associated with oxidative stress such as diabetes, cancer, atherosclerosis, and hypertension as well as inflammation. AIM OF THE STUDY The leaf extract from P. karwinskii was examined to identify its compounds and elucidate its inhibitory effect on reactive oxygen species as well as its anti-inflammatory activity and gastroprotective effects in an animal model. MATERIALS AND METHODS Compounds were identified via ultra-high-performance liquid chromatography coupled with electrospray ionization with quadrupole time of flight-mass spectrometry. Inhibition of reactive oxygen species was determined ex vivo in peripheral blood mononuclear cells with 2',7'-dichlorodihydrofluorescein diacetate. The anti-inflammatory activity was assessed using a carrageenan-induced paw edema model in Wistar rats; nitric oxide and tumor necrosis factor alpha levels were quantified. The gastroprotective effect was evaluated in Wistar rats with indomethacin-induced gastric injury. RESULTS Nine compounds were identified in the P. karwinskii leaf extract. Most compounds, such as quinic acid, malic acid, neochlorogenic acid, chlorogenic acid, rutin, embelin, pinellic acid, and azelaic acid, were reported to exhibit antioxidant and/or anti-inflammatory activity. The extract was also found to inhibit reactive oxygen species in the ex vivo model. Unlike other anti-inflammatory drugs, the extract exerted a dual effect: anti-inflammatory activity and protection of the gastric mucosa. The results showed that the extract could significantly inhibit the release of nitric oxide without a dose-response relationship. CONCLUSION P. karwinskii leaf extract inhibited reactive oxygen species and exerted an anti-inflammatory effect. Moreover, this extract did not induce gastric damage in the animals. The bioactivity of the species was found to support its use in traditional medicine. This orchid could be used to treat inflammatory diseases without causing the side effects associated with nonsteroidal anti-inflammatory drugs. It can also be employed to treat other pathological conditions associated with oxidative stress. The findings herein form the basis for the future discovery of natural products that may serve as safe alternative therapies for inflammatory disorders.

Abstract
BACKGROUND Previous in vitro experiments have demonstrated that prostaglandin F2-alpha (PF2α) reduced proliferation and adipogenesis in a murine cell line and human orbital fibroblasts derived from subjects with inactive Graves' orbitopathy (GO). The objective of this study was to determine if the PGF2α analogue bimatoprost is effective at reducing proptosis in this population. METHODS A randomized controlled double-masked crossover trial was conducted in a single tertiary care academic medical center. Patients with long-standing, inactive GO but persistent proptosis (>20 mm in at least one eye) were recruited. Allowing for a 15% dropout rate, 31 patients (26 females) were randomized in order to identify a treatment effect of 2.0 mm (p = 0.05; power 0.88). Following informed consent, participants were randomized to receive bimatoprost or placebo for three months, after which they underwent a two-month washout before switching to the opposite treatment. The primary outcome was the change in exophthalmometry readings over the two three-month treatment periods. RESULTS The mean exophthalmometer at baseline was 23.6 mm (range 20.0-30.5 mm), and the mean age of the patients was 55 years (range 28-74 years). The median duration of GO was 7.6 years (interquartile range 3.6-12.3 years). The majority were still suffering from diplopia (61.3%) with bilateral involvement (61.3%). Using multi-level modeling adjusted for baseline, period, and carry-over, bimatoprost resulted in a -0.17 mm (reduction) exophthalmometry change ([confidence interval -0.67 to +0.32]; p = 0.490). There was a mean change in intraocular pressure of -2.7 mmHg ([confidence interval -4.0 to -1.4]; p = 0.0070). One patient showed periorbital fat atrophy on treatment, which resolved on stopping treatment. Independent analysis of proptosis by photographic images (all subjects) and subgroup analysis on monocular disease (n = 12) did not show any apparent benefit. CONCLUSIONS In inactive GO, bimatoprost treatment over a three-month period does not result in an improvement in proptosis.

Identification of Oxygenated Fatty Acid as a Side Chain of Lipo-Alkaloids in Aconitum carmichaelii by UHPLC-Q-TOF-MS and a Database. Molecules 2016; 21:437. [PMID: 27043515 PMCID: PMC6273321 DOI: 10.3390/molecules21040437] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Revised: 03/24/2016] [Accepted: 03/28/2016] [Indexed: 11/24/2022] Open
Abstract
Lipo-alkaloid is a kind of C19-norditerpenoid alkaloid usually found in Aconitum species. Structurally, they contain an aconitane skeleton and one or two fatty acid moieties of 3–25 carbon chains with 1–6 unsaturated degrees. Analysis of the lipo-alkaloids in roots of Aconitum carmichaelii resulted in the isolation of six known pure lipo-alkaloids (A1–A6) and a lipo-alkaloid mixture (A7). The mixture shared the same aconitane skeleton of 14-benzoylmesaconine, but their side chains were determined to be 9-hydroxy-octadecadienoic acid, 13-hydroxy-octadecadienoic acid and 10-hydroxy-octadecadienoic acid, respectively, by MS/MS analysis after alkaline hydrolysis. To our knowledge, this is the first time of the reporting of the oxygenated fatty acids as the side chains in naturally-occurring lipo-alkaloids. In order to identify more lipo-alkaloids, a compound database was established based on various combinations between the aconitane skeleton and the fatty acid chain, and then, the identification of lipo-alkaloids was conducted using the database, UHPLC-Q-TOF-MS and MS/MS. Finally, 148 lipo-alkaloids were identified from A. carmichaelii after intensive MS/MS analysis, including 93 potential new compounds and 38 compounds with oxygenated fatty acid moieties.
