Discovery of quality control ingredients in burdock root by combining anti-tumor effects and UHPLC-QqQ-MS/MS.

Burdock root is the root of Arctium lappa L., a plant of the Compositae family, which has the effects of dispersing wind and heat, detoxifying and reducing swelling. In order to better control the quality of burdock root, a screening study of quality control indicators was carried out. The current research combines biological activity evaluation with chemical analysis to screen and identify the biologically active compounds of burdock root as chemical components for the quality control of herbal medicine. The efficacy of 10 batches of ethanol extracts of burdock roots was evaluated by a tumor inhibition experiment in S180 tumor-bearing mice. The five main chemical components of these extracts were simultaneously quantitatively measured by ultra-high performance liquid chromatography combined with triple quadrupole mass spectrometry. Pearson correlation analysis was used to establish the relationship between these extracts' biological activity and chemical properties. The results showed that chlorogenic acid, caffeic acid and cynarin were positively correlated with the effect of inhibiting tumor growth, and further bioassays confirmed this conclusion. In conclusion, chlorogenic acid, caffeic acid and cynarin can be used as quality control markers for burdock root's antitumor effect.

Optimization of Aqueous Extraction Conditions of Inulin from the Arctium lappa L. Roots Using Ultrasonic Irradiation Frequency

Ultrasound-assisted extraction is a promising technique to obtain active compounds from plants with high efficiency. The present study was conducted in two sections. In the first phase, the effect of solvent type (methanol, ethanol, water, and water-ethanol (50 : 50, v/v)) on inulin extraction yield from burdock roots (Arctium lappa L.) was investigated by the conventional method. The second phase aim was to optimize the condition of inulin and phenolic compounds including sonication time (10–40 min), sonication temperature (40–70°C), and solid/solvent ratio (1 : 20–1:40 g/ml) using response surface methodology (RSM). The results demonstrated that the highest inulin efficiency was extracted by water in the conventional method, which is equal to 10.32%. The optimum conditions of ultrasound-assisted water extraction for independent variables including sonication time and temperature as well as solid/water ratio were 36.65 min, 55.48°C, and 1 : 35 g/ml, respectively, which were determined on the maximization of inulin and total phenol content and minimization of IC50. At this optimum condition, inulin yield, phenolic compounds, and IC50 were found to be 12.46%, 18.85 mg GA/g DW, and 549.85 µg/ml, respectively. Regarding the results of this research, ultrasound-assisted extraction can be used as an alternative to the conventional extraction methods in extracting bioactive compounds from medicinal plants because it may improve the mass transfer, reducing the extraction time and the solvent used.

A Study on the Synbiotic Composition of Bifidobacterium bifidum and Fructans from Arctium lappa Roots and Helianthus tuberosus Tubers against Staphylococcus aureus.

A number of mechanisms have been proposed explaining probiotics and prebiotics benefit human health, in particular, probiotics have a suppression effect on pathogen growth that can be enhanced with the introduction of prebiotics. In vitro models enhanced with computational biology can be useful for selecting a composition with prebiotics from new plant sources with the greatest synergism. Water extracts from burdock root and Jerusalem artichoke tubers were purified by ultrafiltration and activated charcoal and concentrated on a rotary evaporator. Fructans were precipitated with various concentrations of ethanol. Bifidobacterium bifidum 8 VKPM AC−2136 and Staphylococcus aureus ATCC 43300 strains were applied to estimate the synbiotic effect. The growth of bifidobacteria and staphylococci in monocultures and cocultures in broths with glucose, commercial prebiotics, as well as isolated fructans were studied. The minimum inhibitory concentrations (MICs) of lactic and acetic acids for the Staphylococcus strain were determined. A quantitative model joining the formation of organic acids by probiotics as antagonism factors and the MICs of pathogens (as the measure of their inhibition) was tested in cocultures and showed a high predictive value (R2 ≥ 0.86). The synbiotic factor obtained from the model was calculated based on the experimental data and obtained constants. Fructans precipitated with 20% ethanol and Bifidobacterium bifidum have the greater synergism against Staphylococcus.

Effect of in vitro gastro-intestinal digestion on the phenolic composition and antioxidant capacity of Burdock roots at different harvest time

The current study aimed to evaluate how the harvest time affects the phenolic composition in Burdock root flours (BRF) and how these phenolics are influenced by the gastro-intestinal digestive environment. Burdock roots were harvested in 2020 in Jiangsu Province in June (B1), July (B2) and August (B3). The main phenolic, 5-O-caffeoylquinic acid (5-CQA) decreased after in vitro digestion from 1.14 to 0.22 mg/g (B1 < B2 < B3). Total phenolic content of BRF was 61% lower after in vitro digestion whereas 5-CQA bioaccessibility remained at about 60%. Twelve other phenolic compounds were tentatively identified after in vitro digestion. An average reduction in antioxidant capacity of 27% and 10% was observed for DPPH and ABTS, respectively. In conclusion, data demonstrated that phenolic composition, bioaccessibility and antioxidant capacity of Burdock roots harvested at different times were subject to the influence of in vitro gastrointestinal digestion.

Effect of Drying Methods on Volatile Compounds of Burdock (Arctium lappa L.) Root Tea as Revealed by Gas Chromatography Mass Spectrometry-Based Metabolomics.

Burdock (Arctium lappa L.) is one of the nutritional foods widely planted in many countries. Dried burdock root (BR) is available as a herbal tincture and tea in many Asian countries with good flavor and taste. In this study, the volatile components in dried BR were identified and the effects of different drying methods on the volatile components were investigated by HS-GC-MS method. A total of 49 compounds were identified. Different drying methods including hot-air drying (HD, at 50, 60, 70, and 80 °C), vacuum drying (VD, at 50, 60, 70, and 80 °C), sunlight drying (SD), natural drying (ND), and vacuum freeze drying (VFD) were evaluated by HS-GC-MS-based metabolomics method. Results showed that different drying methods produced different effects on the volatile compounds. It was observed that 2,3-pentanedione, 1-(1H-pyrrol-2-yl)-ethanone, furfural, and heptanal were detected at higher concentrations in HD 80 and VD 70. The traditional HD and SD methods produced more flavor substances than VFD. The BR treated by the VFD method could maintain the shape of the fresh BR pieces while HD50 and VD80 methods could maintain the color of fresh BR pieces. These findings could help better understand the flavor of the corresponding processed BR and provide a guide for the drying and processing of BR tea.

ГАЗОХРОМАТОГРАФИЧЕСКИЙ АНАЛИЗ ХИМИЧЕСКОГО СОСТАВА ЭТИЛОВОГО СПИРТА, ПОЛУЧЕННОГО ИЗ РАСТЕНИЙ РОДА ASTERACEAE

In recent years, serious attention has been paid around the world to the chemical and biotechnological processing of biomass of easily renewable plant raw materials. One of the most mass-produced aliphatic alcohols is ethyl alcohol. The aim of this work was gas chromatographic analysis of the chemical composition of ethyl alcohol obtained from plants of the genus Asteraceae (dahlia and jerusalem artichoke tubers, chicory and big burdock roots) growing on the territory of Kazakhstan. The article discusses the methods of obtaining and application of ethyl alcohol. The results of the analysis of the chemical composition of ethyl alcohol obtained from plants of the genus Asteraceae are presented. As a result of the study, alcohols were obtained in different concentrations. The chemical composition of ethyl alcohol was determined by gas chromatography. The impurity composition of ethyl alcohol obtained from various types of raw materials is also shown. The composition of impurities in various samples of ethanol and alcohol-containing products is considered in detail. The results of the study were discussed, and the peculiarities of using the gas chromatography method were shown.

Use of water-alcohols treatment of medicinal plants under conditions modeling intoxication by lead and cadmium

The results of studying the effects of water-alcohol infusions of medicinal plants - rhizomes of thick-leafed incense (Bergenia crasslifolia L. Fritsch), dioica nettle leaves (Urtica dioca L.), burdock roots (Arctium lappa L.), and mother-and-leaf leaves - are presented. ordinary machichi (Tussilago farfara L.) on the organism of laboratory rats under conditions of short-term intoxication with heavy metals in doses of 25 mg of lead and 2.5 mg of cadmium per 1 kg of live weight. In the course of studies it was found that the effect of heavy metals on the body of laboratory animals is selective - the main “depot” of lead was bone tissue, and cadmium - the kidneys and liver. The addition of 1 ml of water-alcohol infusions from medicinal raw materials to the diet of rats as detoxicants caused a decrease in the level of lead in the animal organism to 6.32 times, cadmium to 3.46 times. The greatest detoxification ability was shown by infusions of the roots of burdock and leaves of nettle dioecious. Under the influence of elevated doses of lead and cadmium in laboratory animals there was an increase in heart mass by 40.34 % and spleen by 89.91 %, a decrease in the content of alkaline phosphatase in blood serum by 25.81 %. Water-alcohol infusions normalized the biochemical parameters of rat blood serum. Studies have shown that the infusions of rhizomes of thick-leafed frangipani, burdock roots, dioecious nettles and coltsfoot leaves with antioxidant properties can be the basis for the development of an effective herbal preparation used for the prevention and treatment of animals from intoxication with salts of heavy metals.

Exercise training and burdock root (Arctium lappa L.) extract independently improve abdominal obesity and sex hormones in elderly women with metabolic syndrome

The prevalence of metabolic syndrome (MS) is increasing among the elderly, and new lifestyle-based treatment strategies are warranted. We conducted a randomized, double-blind controlled trial of the effects of aquatic exercise (AE) and/or consumption of burdock root extract (BE) on body composition and serum sex hormones, i.e., testosterone, estradiol, sex hormone-binding globulin (SHBG), and dehydroepiandrosterone-sulfate (DHEA-S) in elderly women with MS. The percentage of abdominal fat was decreased in the AE group. Waist circumference was increased in the control (CON) group, but not in the other groups. SHBG and estradiol levels were enhanced by both AE and BE and correlated with changes in fat-related body composition. DHEA-S levels only increased in the BE group, which was consistent with changes in lean body mass. Testosterone levels decreased in the CON group, which correlated with changes in lean body mass, skeletal muscle mass, body fat, and waist circumference. Our findings suggested that the combined AE/BE intervention exerted no synergistic and/or additive effects on any sex-related outcome measures in elderly women with MS.

Дикорастущее растительное сырьё – источник обогащающих добавок к пище

Gentle technologies have been developed for processing wild plant raw materials growing on the territory of the Krasnoyarsk Territory, namely large burdock, medicinal dandelion, medicinal hemophlebus, common yarrow, carried out in order to obtain natural food fortifiers for bakery, flour confectionery and other food products. Vegetable powders of various degrees of grinding, with a particle size of 60-180mkm and less than 60mkm, containing inulin and other substances useful for health, were obtained. The technology of obtaining inulin from burdock and dandelion officinalis has been developed. A method of drying vegetable raw materials with infrared rays of various wavelengths was applied and studied. The obtained kinetic drying curves allowed us to establish that the drying rate depends on the type of raw material. As a result, drying modes (wavelength, heat flux power, duration) were determined for different parts of plants: for the aboveground part (leaves and inflorescences) and roots. The process of storing the obtained powders in sealed polymer packages of 3-5 kg at a temperature of (20±5)°C and relative humidity (70±5)% was studied. According to the results of organoleptic, physico-chemical and microbiological indicators, the shelf life of powders under these conditions is 18 months. Technical documentation for powders has been developed, approved and approved: roots of burdock, dandelion, medicinal hemophlebus and yarrow.

Aqueous extract of Arctium lappa L. root (burdock) enhances chondrogenesis in human bone marrow-derived mesenchymal stem cells

BackgroundArctium lappa L. root (burdock root) has long been recommended for the treatment of different diseases in traditional Chinese medicine. Burdock root possesses anti-oxidative, anti-inflammatory, anti-cancer, and anti-microbial activities. The aim of the study was to elucidate whether aqueous extract of burdock root regulates mesenchymal stem cell proliferation and differentiation.MethodsHuman bone marrow-derived mesenchymal stem cells in 2D high density culture and in 3D micromass pellets were treated with chondrogenic induction medium and chondral basal medium in the absence or presence of aqueous extract of burdock root. The chondrogenic differentiation was accessed by staining glucosaminoglycans, immunostaining SOX9 and type II collagen and immuonblotting of SOX9, aggrecan and type II collagen.ResultsTreatment of aqueous extract of burdock root increased the cell proliferation of hMSCs. It did not have significant effect on osteogenic and adipogenic differentiation, but significantly enhanced chondrogenic induction medium-induced chondrogenesis. The increment was dose dependent, as examined by staining glucosaminoglycans, SOX9, and type II collagen and immunobloting of SOX9, aggrecan and type II collagen in 2D and 3D cultures. In the presence of supplemental materials, burdock root aqueous extract showed equivalent chondrogenic induction capability to that of TGF-β.ConclusionsThe results demonstrate that aqueous extract of Arctium lappa L. root promotes chondrogenic medium-induced chondrogenic differentiation. The aqueous extract of burdock root can even be used alone to stimulate chondrogenic differentiation. The study suggests that the aqueous extract of burdock root can be used as an alternative strategy for treatment purposes.

Diminution of Proliferation, Migration, and Invasion of Melanoma Cells by Arctium Lappa L. Extracts

As a highly aggressive form of human cancer, melanoma is prone to metastasis, leading to 75% of all skin cancer deaths. The 5-year-survival rate of melanoma is below 20%. Therefore, new therapies for melanoma are urgently needed. Burdock (Arctium lappa L) root - known for its antitumor, antioxidant, anti-inflammatory, antiviral, neuroprotective, and endoplasmic reticulum stress regulatory effects - was evaluated for its effects on the proliferation and apoptosis of melanoma cells and its possible mechanism. The results show suppression of the proliferation and stimulation of apoptosis of A375 cells in vitro. Additionally, it suppressed the PI3K/AKT pathway in A375 cells. These data suggest burdock (A. lappa L) root preparation as a promising drug for the treatment of melanoma.

Flavonoid-profile determination for a hypoglycemic collection by high-performance liquid chromatography

Objectives. Herbal hypoglycemic drugs complement the conventional approach to the treatment of type-2 diabetes based on the use of synthetic prescription drugs. However, their scientifically based application and standardization are limited due to inadequate and often outdated information on their chemical composition. Accordingly, we have developed a hypoglycemic collection (HGС) consisting of common bean pods (Phaseolus vulgaris L.), bilberry shoots (Vaccinium myrtillus L.), galega herb (Gallega officinalis L.), common knotgrass herb (Polygonum aviculare L.), burdock roots (Arctium lappa L.), and cinnamon rose hips (Rosa cinnamomea L.). According to a number of researchers, the antidiabetic properties of these herbs are largely due to the presence of polyphenolic compounds, especially flavonoids. The aim of this study was to determine the profile of flavonoids in the HGС and in its total dry extract (TDE).Methods. The study was performed by reverse-phase high-performance liquid chromatography with diode array and mass spectrometric detection.Results. Nine individual flavonol glycosides—derivatives of myricetin, quercetin, kaempferol and kaempferide—were identified in the HGC and the TDE. The main flavonol glycosides in the studied objects were robinin and kaempferol-3-glucuronide, the contents of which in the HGC were 2.09 and 2.22 mg/g, in the TDE 4.85 and 3.84 mg/g, respectively. The other flavonol glycosides were determined in the HGC and its TDE at significantly lower concentrations.Conclusions. The method developed in the study can be used to standardize HGCs and estimate their pharmacological activities.

EFFECT OF PRESSURE LIQUID EXTRACTION AND ULTRASONIC IRRADIATION FREQUENCY ON INULIN, PHENOLIC CONTENT AND ANTIOXIDANT ACTIVITY IN BURDOCK (Arctium lappa L.) ROOTS

Burdock (Arctium lappa L.) roots are traditionally used in folk medicine as diuretic and curing rheumatism, gastritis, gout, throat pain, arthritis and rashes. These pharmacological properties are due to many bioactive compounds such as flavonoids and fructooligosaccharides. Nowadays, the the application of “green” methods for extraction of natural compounds gains more and more attention. The object of the current research was to determine inulin and sugars content, phenolic content and antioxidant potential in 70% ethanol and water extracts obtained by two “green“ extraction methods, namely pressure-liquid extraction and ultrasound-assisted techniques. The content of total fructans, as well as inulin and sugars were analyzed by spectrophotometric resorcinol-thiourea method and high-performance liquid chromatography with refractive index detection. Total phenols and flavonoids were determined by Folin-Chiocalteu and Al(NO3)3 reagents. Antioxidant activity was evaluated by four reliable methods (DPPH, ABTS, FRAP and CUPRAC). The established inulin content varied from 0.27 to 4.0 g/100 g dw in prevalence of the ultrasound-assisted extract obtained with water. Additionally, the established phenolic compounds content (from 10.35 to 18.16 mg gallic acid equivalent (GAE)/g dw) and antioxidant activities demonstrated the burdock roots as potential source phytonutrients with health beneficial properties.

Anti-Acne Action of Peptides Isolated from Burdock Root-Preliminary Studies and Pilot Testing.

This work aimed to study the anti-bacterial, anti-biofilm and anti-oxidant potential effects of low molecular weight (LMW) peptides (Br-p) isolated from burdock (Arctium lappa L.) roots. We conducted a preliminary study to exclude or confirm the antibiotic activity of the LMW peptides fraction of this plant. Br-p were isolated using gel filtration and a 10 kDa cut-off membrane. The obtained peptides were identified by MALDI TOF/TOF. Antibacterial activity was tested against acne strains using diffusion tests, MIC and MBC. The fibroblast cytotoxicity of Br-p was tested, and the selectivity index (SI) value was determined. The fraction of 46 Br-p peptides isolated from burdock root with a molecular weight below 5000 Da and theoretic pI (isoelectric point) of 3.67–11.83 showed a narrow spectrum of activity against Gram-positive acne bacterial strains. One of the Br-p peptides assessed on MALDI RapidDeNovo was LRCDYGRFFASKSLYDPLKKRR cationic peptide. It was analogous to that contained in A. lappa protein, and theoretically it was matched as a peptide with antibiotic nature. Br-p did not show toxicity to fibroblasts in the tested concentration up to 10 mg/mL, obtaining CC50 10 mg/mL. The SI value for the tested Propionibacterium strains ranged from 160 to 320. Finally, an active dressing based on chitosan/alginate/genipin was prepared using freeze-drying. The formed dressing was evaluated for its anti-acne activity. To sum up: preliminary biological studies confirmed the anti-acne properties of the isolated peptide fraction from burdock root and pointed to the possibility of using it to create an active dressing on the skin.

Effect of Dose and Timing of Burdock (Arctium lappa) Root Intake on Intestinal Microbiota of Mice.

Water-soluble dietary fiber such as inulin improves the beta diversity of the intestinal microbiota of mice fed with a high-fat diet (HFD). The circadian clock is the system that regulates the internal daily rhythm, and it affects the pattern of beta diversity in mouse intestinal microbiota. Burdock (Arctium lappa) root contains a high concentration of inulin/fructan (approximately 50%) and is a very popular vegetable in Japan. Arctium lappa also contains functional substances that may affect intestinal microbiota, such as polyphenols. We compared the effects of inulin and A. lappa powder on the diversity of the intestinal microbiota of HFD-fed mice. 16S rDNA from the intestinal microbiota obtained from feces was analyzed by 16S Metagenomic Sequencing Library Preparation. It was found to have a stronger effect on microbiota than inulin alone, suggesting that inulin has an additive and/or synergic action with other molecules in A. lappa root. We examined the effects of intake timing (breakfast or dinner) of A. lappa on intestinal microbiota. The intake of A. lappa root in the evening had a stronger effect on microbiota diversity in comparison to morning intake. Therefore, it is suggested that habitual consumption of A. lappa root in the evening may aid the maintenance of healthy intestinal microbiota.

Burdock (Arctium lappa L.) root attenuates preneoplastic lesion development in a diet and thioacetamide-induced model of steatohepatitis-associated hepatocarcinogenesis.

Nonalcoholic steatohepatitis (NASH) is considered growing risk factor for hepatocellular carcinoma development in high-income countries. Diet- and chemically induced rodent models have been applied for the translational study of NASH-associated hepatocarcinogenesis due to their morphological and molecular similarities to the corresponding human disease. Arctium lappa L. (burdock) root tea has been extensively consumed in Traditional Chinese Medicine due to its potential therapeutic properties. Indeed, the bioactive compounds of A. lappa root, as the polyphenols, have already showed antioxidant and anti-inflammatory properties in different in vivo and in vitro bioassays. In this study, we investigated whether burdock root ethanolic extract (BRE) administration attenuates NASH-associated hepatocarcinogenesis. Eight-week-old male Wistar rats received choline-deficient high-fat diet for 8 weeks and multiple thioacetamide doses for 4 weeks in order to induce NASH and preneoplastic glutathione-S-transferase pi (GST-P)+ preneoplastic foci. Subsequently, rats were treated with BRE (100 or 200 mg/kg body weight) or vehicle by oral gavage for 2 weeks. BRE displayed high levels of chlorogenic and caffeic acids and BRE administration reduced total fatty acid and lipid hydroperoxide levels, while increasing the activities of antioxidant superoxide dismutase and catalase enzymes in the liver. Furthermore, burdock intervention diminished the size of GST-P+ remodeling preneoplastic lesions (PNLs) and displayed a trend on reducing hepatocyte proliferation (Ki-67) inside them. These findings suggest that short-term exposure to BRE alleviated remodeling PNL development in NASH-associated hepatocarcinogenesis.

Effect of Both Phytoestrogen and Xenoestrogen on Some Sexual Hormones in Male Albino Rats and Illustration of The Effect of Arctium Lappa L (A. Lappa) on Their Actions

Background: Xenoestrogens are chemically distinct industrial products potentially able to disrupt the endocrine system by mimicking the action of endogenous steroid hormones. Phytoestrogens are naturally occurring non-steroidal plant chemicals that can act like the female hormone estrogen. Arctium lappa (burdock) root has traditionally been recommended as an aphrodisiac agent. Objective: The aim of the study was to clarify the effect of both bisphenol-A (BPA) and anise oil together on some sexual hormones and illustration the effect of A. lappa on their actions. Materials and methods: The study was conducted on thirty male albino rats. The animals were divided into three groups: Group I, control untreated group, Group II, rats treated with bisphenol-A and anise oil and Group III, rats treated with BPA and anise oil in addition to A. lappa. Blood samples were collected to estimate biochemical parameters. Results: The biochemical results showed highly significant increase (p < 0.01) in the activities of ALT, AST, urea, creatinine, FSH, prolactin, total cholesterol, triglycerides, LDLC, VLDL, LDL/HDL and TC/HDL levels. While, there was highly significant decrease (p < 0.01) in HDLC, total protein, albumin, globulin, testosterone and, LH. All these results turned back to the normal values after receiving the A. lappa as compared to normal group. Conclusion: it could be concluded that phytoestrogen and xenoestrogen have undesirable effects and it's recommended to minimize the utilization of these compound to protect people from its hazardous effects.
