Abstract
OBJECTIVES This study aims to evaluate the pharmacological role of indigo extract in accelerating the wound healing in a rat model. METHODS Female Sprague-Dawley rats were anesthetized with ketamine (30 mg/kg, i.p.) and the full thickness of the marked skin was then cut carefully and wounds were left undressed. Indigo extract (5%) in PBS was applied topically twice daily until healing was complete. A control group of rats was treated with povidone-iodide (Betadine®). Rats treated with phosphate buffer saline were used as a negative control group. The rate of wound healing was assessed daily. Histopathological examination of skin sections were qualitatively assessed by independent evaluators. The inflammatory and apoptotic markers were assessed in skin tissue homogenates using ELISA. RESULTS Histopathology data showed that applying indigo to skin wounds enhanced the healing process, resulting in a significant decrease in dermal inflammation in comparison to untreated rats. Topical application of indigo significantly increased antioxidant enzyme activities with reduced malondialdehyde (MDA) levels in wound tissues. The levels of matrix metalloproteases-2 and -9 were significantly lower with an accompanied increase in the level of TGF-β1 in skin tissues from rats treated with indigo compared to the control group treated with PBS. CONCLUSIONS The antioxidant and anti-inflammatory properties of indigo leaf extract accelerate the healing of skin injuries.

Cell extraction method coupled with LC-QTOF MS/MS analysis for predicting neuroprotective compounds from Polygonum tinctorium. J Pharm Biomed Anal 2022; 220:114988. [PMID: 35994944 DOI: 10.1016/j.jpba.2022.114988] [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: 05/23/2022] [Revised: 07/07/2022] [Accepted: 08/06/2022] [Indexed: 11/24/2022]
Abstract
The cell extraction method coupled with LC-QTOF-MS/MS is a biological screening technique in which cells are incubated with extracts of natural products, which results in potential bioactive compounds selectively combining with various extracellular and intracellular targets. Although the neuroprotective effects of the plant Polygonum tinctorium are unknown, the ethyl acetate (EtOAc) fraction exhibits significant neuroprotective effects against ʟ-glutamate-induced cytotoxicity in HT22 cells. In this study, we attempted to identify the neuroprotective compounds in the EtOAc fraction of P. tinctorium using the cell extraction method coupled with LC-QTOF MS/MS. Potential neuroprotective components derived from P. tinctorium were combined selectively with HT22 cells, and cell-derived metabolites were identified. A new flavonoid compound, 3,5,3',4'-tetrahydroxy-6,7-methylendioxyflavone-3-O-β-ᴅ-glucopyranoside (1), and 14 known compounds (2-15), with compounds 2, 3, 8, 13, and 15 detected by the cell extraction method, were isolated from the EtOAc fraction of P. tinctorium. Compounds 2, 8, 12, and 14 showed strong neuroprotective effects, with compounds 2 and 14 identified in this plant for the first time in this study. Our results indicate that the cell extraction method coupled with LC-QTOF MS/MS is a useful tool for screening and identifying neuroprotective compounds in natural products.

Abstract
Globe amaranth flower, the edible inflorescence of Gomphrena globose L., was used to treat dysentery and ulcer as well as other infectious diseases caused by microbes in Southwest China, but its function and bioactive components need experimental support. In this study, phytochemical constituents and antibacterial bioactivity of globe amaranth flower against P. aeruginosa were carried out. As a result, two new (1 and 2) and eleven known (3-11) compounds were isolated, in which compounds 4-7 displayed anti P. aeruginosa bioactivity with the minimum inhibitory concentration (MIC) from 0.008 to 0.256 mg/mL. Furthermore, with aid of the scanning electron microscope (SEM) and a superficial skin infection model in mice, the most potent compound 4 can significantly destroy the structure of bacteria in vitro and restore bacterial infection damage in vivo.

Abstract
The discovery of new pharmaceutical identities, particularly anti-infective agents, represents an urgent need due to the increase in immunocompromised patients and the ineffectiveness/toxicity of the drugs currently used. The scientific community has recognized in the last decades the importance of the plant kingdom as a huge source of novel molecules which could act against different type of infections or illness. However, the great diversity of plant species makes it difficult to select them with probabilities of success, adding to the fact that existing information is difficult to find, it is atomized or disordered. Persicaria and Polygonum constitute two of the main representatives of the Polygonaceae family, which have been extensively used in traditional medicine worldwide. Important and structurally diverse bioactive compounds have been isolated from these genera of wild plants; among them, sesquiterpenes and flavonoids should be remarked. In this article, we firstly mention all the species reported with pharmacological use and their geographical distribution. Moreover, a number of tables which summarize an update detailing the type of natural product (extract or isolated compound), applied doses, displayed bioassays and the results obtained for the main bioactivities of these genera cited in the literature during the past 40 years. Antimicrobial, antioxidant, analgesic and anti-inflammatory, antinociceptive, anticancer, antiviral, antiparasitic, anti-diabetic, antipyretic, hepatoprotective, diuretic, gastroprotective and neuropharmacological activities were explored and reviewed in this work, concluding that both genera could be the source for upcoming molecules to treat different human diseases.

Anti-inflammatory and bioavailability studies on dietary 3,5,4'-trihydroxy-6,7-methylenedioxyflavone-O-glycosides and their aglycone from indigo leaves in a murine model of inflammatory bowel disease. J Pharm Biomed Anal 2020; 193:113716.

Abstract
Persicaria tinctoria (Aiton) Spach, also called Polygonum tinctorium Lour., (family Polygonaceae) for indigo plant has been traditionally useful as a medicinal or edible plant with a variety of biological activities. Of these, much attention has been paid to their anti-inflammatory activities. We have recently demonstrated that indigo leaves contain high levels of flavonol O-glycosides with 3,5,4'-trihydroxy-6,7-methylenedioxyflavone (TMF) as an aglycone. In this study, we attempted to evaluate anti-inflammatory activities of TMF-O-glycosides and free TMF prepared from indigo leaves after extraction with hot water. Free TMF was found to appreciably down-regulate the gene expression of pro-inflammatory cytokines including interleukin (IL)-1β, IL-6, inducible nitric oxide, and tumor necrosis factor-α in cultured macrophage cells stimulated with lipopolysaccharide while up-regulating the expression of anti-inflammatory IL-10. However, no study has been conducted regarding in vivo anti-inflammatory activities of TMF-O-glycosides and free TMF until now. Here, we assessed in vivo anti-inflammatory effects of these dietary compounds on ulcerative colitis in a murine model of inflammatory bowel disease by the induction with dextran sulfate sodium (DSS). Histological evaluation revealed that both TMF-O-glycosides and free TMF effectively protected against DSS-induced ulcerative colitis. The analysis of digested products by liquid chromatography and mass spectrometry led us to detect free TMF as a predominant metabolite in the feces of mice fed with TMF-O-glycosides. Moreover, free TMF was later detected as glucuronyl conjugates of TMF in the liver of mice fed with both fractions. These results indicate the effective digestion of TMF-O-glycosides and the subsequent absorption of free TMF in the gut of mice for exerting anti-inflammatory effects. Taken together, our findings suggest that dietary TMF-O-glycosides could be promising natural sources for the utilization as herbal medicine and nutraceuticals to expect in vivo anti-inflammatory activities.

Abstract
Background:The α-glucosidase (EC 3.2.1.20), a calcium-containing intestinal enzyme which is positioned in the cells which cover the intestinal microvilli brush border. The carbohydrates require metabolism by α-glucosidase before being absorbed into the small intestine, and as a result, this enzyme represents a significant drug target for the effective management of diabetes. There are few α- glucosidase inhibitors in the clinical practice that is challenged by several limitations. Thus, new effective and safe therapeutic agents in this class are required. In this regard, plant secondary metabolites are a very promising source to be investigated. Herein in this review, we have focused on the preclinical studies on various glycosides with in vitro α-glucosidase inhibitory activity.Methods:The literature available on various websites such as GoogleScholar, PubMed, Scopus. All the peer-reviewed articles were included without considering the impact factor.Results:The surveyed literature revealed marked inhibitory profile of various glycosides derived from plants, and some of them were extremely potent relatively to the standard, acarbose in preclinical trials and exhibited multiple targeted effects.Conclusion:Keeping in view the results, these glycosides are strong candidates for further, more detailed studies to ascertain their clinical potential and for effective contribution in effective management of diabetes, where multiple targets are required to address

Abstract
Polygonum tinctorium Lour. (family Polygonaceae), known as indigo plant, has been useful as a medicinal or edible plant abundant in polyphenolic compounds. We have recently shown that flavonol O-glycosides with 3,5,4′-trihydroxy-6,7-methylenedioxyflavone (TMF) are predominant flavonoids in indigo leaves. However, no study has been performed regarding changes in the levels of flavonoid species during the germination and growth of indigo plant. Here, we attempted to determine the individual constituents of flavonol O-glycosides and the changes in their contents of the seeds, sprouts, and aerial parts. These results revealed that only the seeds predominantly contained flavonol O-(acetyl)-rhamnosides with quercetin or kaempferol as an aglycone. During the development of the sprouts and aerial parts, flavonol O-glycosides with TMF as an aglycone became mainly detectable and accounted for 79.4% and 74.9% of total flavonol O-glycosides from the extracts of aerial parts harvested in 2016 and 2017, respectively. Of the plant organs tested, the aerial parts exhibited the highest antioxidant activities concomitant with greatly increased levels of total polyphenols. Thus, we were able to conduct the identification and quantification of flavonol O-glycosides from the seeds, sprouts, and aerial parts of indigo plant and to evaluate antioxidant activities of their extracts. Taken together, our findings clearly provide the evidence that the aerial parts of indigo plant are a rich source of flavonol O-glycosides with TMF and exhibit much higher antioxidant activities, indicating the usefulness for the application to food and nutraceutical purposes.

Abstract
This study was carried out to investigate the antimelanogenic effects of a Polygonum tinctorium flower extract obtained using red nuruk, a traditional Jeju barley-based fermentation starter. We also studied the mechanism of action of the P. tinctorium fermented flower extract (PTFFE) in mouse melanoma cells (B16F10). Cells were treated with various concentrations (62.5, 125 and 250 μg/mL) of PTFFE and the results showed that PTFFE significantly decreased the melanin content and tyrosinase activity without being cytotoxic. In addition, PTFFE strongly inhibited the expression of tyrosinase and tyrosinase-related protein 2 by decreasing the expression of the microphthalmia-associated transcription factor, as shown by a western blot assay. Furthermore, PTFFE inhibited melanogenesis via upregulation of the phosphorylation of extracellular signal-regulated kinase (ERK) and protein kinase B, also known as AKT. We also used inhibitors such as PD98059 (a specific ERK inhibitor) or LY294002 (an AKT inhibitor) to determine whether the signaling pathways are involved. High-performance liquid chromatography fingerprinting showed the presence of a quercetin glucoside (isoquercitrin) and quercetin in PTFFE. To test the potential for PTFFE application as a cosmetic material, we also performed a primary skin irritation test on human skin. In this assay, PTFFE did not induce any adverse reactions at the treatment dose. Based on these results, we suggest that PTFFE may be considered a potential antimelanogenesis candidate for topical applications.

Abstract
We attempted to evaluate the contents and distribution of antioxidants in the whole seeds, seed shells, and peeled seeds of the Japanese horse chestnut. The seed shells exhibited the highest antioxidant activities due to the presence of highly polymeric proanthocyanidins as we have reported recently. On the other hand, the peeled seeds predominantly contained flavonols such as quercetin and kaempferol at a high level of 66.7% of total polyphenols, also contributing to the predominant antioxidant activities. The instrumental analysis of the extract from the whole seeds revealed the identification of eight flavonol O-glycosides, including six compounds with quercetin and two species with kaempferol as aglycones. The isolated species exhibited different antioxidant activities depending on the types of aglycones, glycosides, and acylated moieties. The results indicate that the peeled seeds are a good source of flavonol O-glycosides serving as antioxidants to be used for food additives and dietary supplements.

A Novel Reduplicate Strategy for Tracing Hemostatic Compounds from Heating Products of the Flavonoid Extract in Platycladi cacumen by Spectrum-Effect Relationships and Column Chromatography. Molecules 2015; 20:16970-86. [PMID: 26393545 PMCID: PMC6332512 DOI: 10.3390/molecules200916970] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2015] [Revised: 09/08/2015] [Accepted: 09/11/2015] [Indexed: 11/16/2022] Open
Abstract
Platycladi cacumen and its processed product have been utilized as a Chinese medicine to treat hemorrhages. In this study, the base peak chromatogram fingerprints of heating products of total flavonoids in Platycladi cacumen were established by high performance liquid chromatography coupled with mass spectroscopy/mass spectroscopy (HPLC-MS/MS), and the hemostatic activities were studied by hemostatic screening tests in vivo. The spectrum-effect relationships between fingerprints and hemostatic activities were analyzed by using canonical correlation analysis to trace the peaks responsible for the significant hemostatic effects. Peak 10 and peak 12 were correlated most closely, thus probably being the main hemostatic compounds. To confirm the reliability of this strategy, the targeted unknown peak was obtained by bioactivity-guided isolation, characterized by MS, 1H-NMR, 13C-NMR, and 2D-NMR spectroscopies, and referred to as cecarbon as a new compound. In addition, the isolated compound exhibited hemostatic effect in a dose-dependent manner with different potencies in vitro and existed in Platycladi cacumen Carbonisatus. A novel dereplication strategy was employed to trace and identify the active compounds of other herbs that have bioactivity enhancement after processing using spectrum–effect relationships and column chromatography.
