RESUMO

BACKGROUND: Herbs are rich in various beneficial bioactive compounds and they can be used for many different purposes. One of the most common is maceration of herbs in alcohol. Different substances respond differently to extraction in prepared solutions. It is very important to enhance the highest proportion of beneficial ingredients during the maceration process in a herbal liqueur. A comparative analysis of numerous different phenolic compounds from eight of the most frequently used herbs for making aperitifs in Europe was performed. RESULTS: In the comparison among all studied herbs, the highest phenolic content was found with Artemisia absinthium (wormwood) (14.61 mg g-1 ) and Mentha piperita (peppermint) (13.89 mg g-1 ), while the lowest content was found with Centaurium erythraea (common centaury) (3.96 mg g-1 ). Salvianolic acid isomers and caffeic acid derivatives were the greatest contributors to the total phenolic content in lemon balm, wormwood, peppermint, fennel and sage. These compounds contain more hydroxyl groups and they were better extracted at the beginning of the maceration process. Caraway and common centaury contain more flavonols (quercetin and kaempferol derivatives), with higher chemical stability and fewer hydroxyl groups in their structure. CONCLUSION: The compositions of eight herbal liqueurs were highly related to the presence of different herbal ingredients and their solubility in the extract over time. Most flavonol derivatives were extracted over a longer time and the two liqueurs (common centaury and caraway) therefore had the highest phenolic contents after 3 weeks of maceration. © 2019 Society of Chemical Industry.

RESUMO

Introduction: Herbal medicine use has become widespread in recent years. This is the first study in Hungary evaluating the use of nutraceutical agents in patients undergoing elective surgery. Aim: The aim of this study was to assess the types, frequency of use and predisposing factors of the most commonly used herbs among patients of an urban hospital and a university clinic. Method: We conducted an anonymous survey questionnaire at the Jávorszky Ödön Hospital and at the 1st Department of Surgery of Semmelweis University. A total of 1000 questionnaires were distributed. Results: In total, 612 questionnaires were returned. 34.3% of patients used herbal remedies, 19.6% of them two weeks prior to surgery. The most commonly used herbs were garlic, chamomile and lemongrass, while in the two-week period before surgery were garlic, ginger and rosehips. 58.5% of the patients had some type of co-morbidity; in this group, the use of herbal remedies was significantly more frequent. 64.4% of patients were expected to undergo general surgical intervention; in this group, the use of herbs was more popular. Analyzing the sociodemographic factors, women, people with a higher level of education, the ones that live in the capital and are over 60 years of age are more likely to use these compounds. Conclusion: One third of patients waiting for surgery used herbal remedies, one fifth of them two weeks prior to surgery. Only one fifth of the patients reported the use of these compounds to their doctors. Orv Hetil. 2020; 161(1): 17-25.

RESUMO

Penaeus monodon is highly susceptible to vibriosis disease. Aims of the study were to identify the pathogen causing vibriosis in P. monodon through molecular techniques and develop a biocontrol method of the disease by application of herbal extracts. Shrimp samples were collected aseptically from the infected farm and the bacteria were isolated from the infected region of those samples. Based on phenotypic identification, several isolates were identified as Vibrio sp. 16S rRNA gene sequences of the selected isolates exhibited 100% homology with V. alginolyticus strain ATCC 17749. An in vivo infection challenge test was performed by immersion method with V. alginolyticus where these isolates caused high mortality in juvenile shrimp with prominent symptoms of hepatopancreatic necrosis. Antibiogram profile of the isolates was determined against eleven commercial antibiotic discs whereas the isolates were found resistant to multiple antibiotics. A total of twenty-one herbal extracts were screened where Emblica officinalis, Allium sativum, and Syzygium aromaticum strongly inhibited the growth of V. alginolyticus in in vitro conditions. In in vivo conditions, the ethyl acetate extracts of E. officinalis and A. sativum successfully controlled the vibriosis disease in shrimp at a dose of 10 mg/g feed. This is the first report on molecular identification and biocontrol of V. alginolyticus in shrimp in Bangladesh.Penaeus monodon is highly susceptible to vibriosis disease.

RESUMO

Introducción: los productos de Cannabis sativa L poseen una eficacia terapéutica conocida desde la Antigüedad, aunque su tipificación farmacológica data de mediados del siglo XX. Recientemente se regularizó su uso en Uruguay. Objetivo: analizar una experiencia clínico terapéutica preliminar con cannabis medicinal (CM) con alto contenido en cannabidiol (CBD). Método: estudio epidemiológico observacional y retrospectivo de una cohorte de 355 pacientes que concurrieron a consultar espontáneamente sobre CM en una clínica privada entre agosto de 2016 y diciembre de 2017. Durante la primera entrevista se recogieron datos demográficos, historia clínica, farmacológica, expectativas y experiencia previa con cannabis. Se indicó mayoritariamente cannabis con alto contenido en CBD (5,25% de CBD y 0,2% de tetrahidrocannabinol (THC)). En consultas siguientes, se investigó el acceso al CM y se valoró su respuesta y efectos adversos mediante escalas analógicas. Se utilizó estadística descriptiva. Resultados: en la cohorte estudiada predominaron mujeres con edad promedio de 67 años, de nivel educativo terciario. Las patologías de consulta fueron neurológicas (38%), enfermedades reumáticas o artro-degenerativas (37%), neoplasias (13%), psiquiátricas (4%) y misceláneas (8%). La mayoría de estos casos (60,6%) refirió mejoría de sus síntomas y solo 16,3% de la población estudiada presentó efectos adversos de grado leve. Los altos costos y la gestión dificultosa para conseguir el CM fueron causas para no iniciar o abandonar el tratamiento. Conclusiones: nuestro estudio preliminar refleja una respuesta terapéutica positiva y sin efectos adversos significativos al CM con alto contenido de CBD. El 60,6% de los pacientes tratados refirió mejoría de sus síntomas. Los factores decisivos para un tratamiento exitoso orientan a facilitar el acceso al CM, mejorando la gestión para su obtención y disminuyendo los costos para una mayor accesibilidad.


Introduction: Cannabis Sativa L. products are known to be therapeutically effective since ancient times, despite its pharmacological typification was made in the mid-20th century. Its use was recently regulated in Uruguay. Objective: to analyse a preliminary clinical-therapeutic experience with MC with high content of cannabidiol (CBD). Method: epidemiological, observational and retrospective study of a 355 patient cohort who spontaneously consulted to learn about CM at a private clinic, between August 2016 and December 2017. Demographic data, medical records, expectation and previous experience with cannabis were collected in the first interview. In most cases, cannabis with high content of CBD was prescribed (5,25 % CBD and 0,2% THC). In subsequent consultations, access to access to MC was invesrtigated and both response to it and adverse effects were studied by means of analogue scales. The study used descriptive statistics. Results: in the cohort studied, women with an average age of 67 years old and university studies prevailed. The following conditions motivated consultations: neurological (38%), rheumatic or bone degenerative diseases (37%), neoplasms (13%), psychiatric diseases (4%) and miscelánea (8%). In most cases (60,6%) patients stated symptoms improved and only 16,3% of the populaiton studied presented mild adverse effects. High costs and difficulties in accessing MC were the reasons for not starting or abandoning treatment. Conclusions: our preliminary study reflects the positive therapeutic response and non significant adverse effects to MC with high content of CBD. 60,6% of patients treated referred improvement in their symptoms. Decisive factors for a successful treatment point at the need to make access to MC easier by improving management to obtain it and reducing costs for a greater accessibility.

RESUMO

BACKGROUND: Urolithiasis is the most common renal system pathology; it affects the health of a many people. Because urolithiasis leads to severe pain, it influences the patient in many aspects. The management of urolithiasis is essential. Herein, we discuss the limitations of the management of urolithiasis with conventional drugs and the possibilities of using natural or herbal pharmacologically active agents beyond conventional drugs. PURPOSE: The drugs presently used for the treatment of urolithiasis have many adverse side effects; therefore, alternatives are needed. Traditional literature suggests that many herbal or natural medicines can be easily made available for the management of urolithiasis and its consequences. METHOD: The data used for this study were collected from various research /review articles, Internet sources, and text books. Literature regarding epidemiology and pharmacological studies performed by various researchers were taken into consideration in this review. The data from the last few decades, reported in different formats, were analyzed. CONCLUSION: The present review reveals the severity of the progression of the occurrence of urolithiasis worldwide. The epidemiology gave in this review clearly indicates that stress-related factors and dietary complications, the key factors in the development of urolithiasis. are increasing. In this review, we acknowledge the limitations of conventional therapy. Many natural drug options are abundantly available throughout the world and can be useful for the management of urolithiasis. Future Perspectives: The development of a suitable formulation of bioactive components obtained from natural sources is being widely researched. However, traditional remedies that are very helpful in the management of urolithiasis and its related complications require scientific support and appropriate standardization for the assessment of their quality and dosage.

RESUMO

The aim of the study was a preliminary study of plant samples collected by targeted expeditions of the department of pharmacobotany (Department of Phytochemistry) of the IG Kutateladze Institute of Pharmacochemistry for the period 2016-2017. In total, 341 objects from (106 various) plants belonging to 36 families and 93 genus were analyzed. The objects were obtained polar and non-polar fractions; flavonoids and triterpenoids were found in them qualitatively. To characterize used P /CH and TLC analysis in various solvent systems. Flavonoids were isolated from Geranium ibericum and Polygonum carneum, which were identified as quercetin-3-0-ß-D-galactopyranoside-hyperin (G. ibericum), 3 5, 7 ', 3'.4' pentahydroxy-flavone - quercetin (G. ibericum, P. сarneum) and quercetin-3-0-rutinozide - rutin (P. сarneum). G. ibericum and P.carneum flora of Georgia are found and studied for the first time. Representatives of the family Asteraceae, Fabaceae, Helleboraceae, Polygonaceae, Scrophula riaceae deserve a particular interest in the content of triterpenoids.

RESUMO

Using data from Schink et al. (2018), a large number of herbal extracts were assessed for their capacity to induce pro- and anti-inflammatory effects based on TLR4 expression normalized for cell viability in two immune cell models (i.e., HeLa-TLR4 transfected reporter cell line, and THP-1 monocytes) applying seven concentrations (0.01-3.0%). The analysis revealed that 70-80% of the extracts satisfying the a priori entry criteria also satisfied a priori evaluative criteria for hormetic concentration responses. These findings demonstrate that a large proportion of herbal extracts display hormetic dose responses in immune cells, indicating that hormetic mechanisms mediate pro- and anti-inflammatory processes and may provide a means to guide optimal dosing strategies. The identification of doses eliciting only anti-inflammatory therapeutic activity as well as the use of dose-variable herbal extracts in the treatment of inflammatory diseases will be challenging.

RESUMO

Through the records of herbal and market investigations,the samples collected from different market and origin were analyzed,and the appearance character indexes were determined in order to revise the commodity specification and grade standard of Dipsaci Radix combined with production practice. This is also to analyze association of the appearance with quality different of intrinsic components. The investigation results indicated the root's long and thick was better,and atrovirens of fracture surface,there are most of the market is dominated by the ungraded goods. Through principal component analysis,variance analysis and cluster analysis,combining with the feasibility of actual operation and herbal record,the length,middle diameter and phloem color were filtrated and the specification was divided into 2 ranks: the selection and ungraded goods,and the grade was divided into 2 ranks for the selection goods: big,small selected goods. Moreover,there were no significant correlation between the appearance and the intrinsic quality index of Dipsaci Radix,the content of extractum were significantly positive correlation with the moisture,but had extremely negative correlation with the total ash. Multiple comparisons indicated that the content of the moisture,extractum and asperosaponin VI of the selected goods were higher than the ungraded goods,while the total ash content were lower,and they hasn't significant difference. The commodity specification and grade standard of Dipsaci Radix as a basis provide commodity specification and grade standard of communities and standardizing market trade order.

RESUMO

The Dao-di herbs are recognized as high-quality Chinese medicines with good medicinal properties. The factors of their growth environment affects the quality of Dao-di herbs. Choosing the right place to produce,rationally planting appropriate local medicinal materials,and improving the quality and yield of authentic medicinal materials are prerequisites for ensuring the steady development of Chinese medicine industry. In this paper,a knowledge model of the relationship between organic medicinal materials and growth environment factors was constructed by integrating the dataset of environmental factors of medicinal materials,and a knowledge base was constructed to provide a decision for the study of suitable medicinal materials under different environmental conditions. Based on this,it is expected to provide a platform for further research on the relationship between the medicinal properties of medicinal herbs and environmental factors.

RESUMO

To evaluate the safety of heavy metals contaminated Astragalus membranaceus,an appropriate protocol was established to study the heavy metals pollution level by health risk assessment. This study provided a detailed procedure to assess the medicinal herbs in quality control and safety evaluation,and expected to create awareness among the public on the safety of consuming of A. membranaceus or any other kinds of medicinal herbs. The heavy metals content of Cu,As,Cd,Pb and Hg in a total of 45 batches of A. membranaceus were carefully analyzed with a developed inductively coupled plasma mass spectrometry( ICP-MS). Besides,the heavy metal contamination level was further evaluated through 4 main assessment parameters,including maximum residue limit( MRL) set by International Standard Organization,estimated daily intake( EDI) set by IUPAC,target hazard quotients( THQ) and Total THQ set by USEPA and total THQs in raw herbs of A. membranaceus. In addition,the recommended MRLs of 5 main heavy metals aimed to A. membranaceus were calculated based on the regulated consumption quantity. The result showed that,under the ISO international standard of Chinese medicine-Chinese herbal medicine heavy metals,the unqualified rate was 8. 89% for A. membranaceus,which including 4 batches of A. membranaceus exceeded the MRL of As. Here,the standard THQ value of A. membranaceus was firstly proposed as 0. 02 and 0. 011 25 for adults and children,respectively,which were calculated with the recommended consumption quantity of 30 g and 9 g for adults and children. Furthermore,the values of THQ for As and total THQs in adults and children were exceeded the standard THQ in A. membranaceus,and the recommended MRLs of Pb,Cd,Hg and Cu in above medicinal materials that calculated based on health risk assessment model were higher than the regulated MRLs that set by ISO and Chinese Pharmacopeia. The research showed that the contents of heavy metals in A. membranaceus were not in the safe range and the certain non-carcinogenic risks to human body cannot be neglected. Based on above investigation result,it is easily known that the common evaluation method for raw herbs based on the comparison of MRL of heavy metals was not precise enough,and the international model of health risk assessment should be built for each medicinal herb. Above all,this study provided a more realistic research approach for safety evaluation of any other kinds of heavy metals contaminated medicinal herbs,including the establishment of heavy metals standard limit in a specified medicinal herb under recommended consumption quantity,and it is expected to create awareness among the public on the safety of consuming any other medicinal herbs.

RESUMO

"Qi medicinal herbs" in China refers to a kind of regional national folk herbs related to the treatment of five labors and seven injuries,the last word of which is "Qi". Our study is to sort out and standardize the name and basic confused varieties through the establishment of " Qi medicinal herbs" VFP information database. " Qi medicinal herbs" variety sorting model of " literature research-variety survey-data mining-spatial distribution" was developed by means of literature analysis which the names and varieties of " Qi medicinal herbs" in the literature were summarized and sorted out. The relationship between the distribution of " Qi medicinal herbs" resources and the use of ethnic groups were visualized by Cytoscape 2. 8. 0 software. The information database of " Qi medicinal herbs" involved in 230 kinds of medicinal materials which including 211 species of plants( including varieties) from 66 families. Medicinal materials standard in China have 9 kinds of " Qi medicinal herbs". Among them,there are 31 kinds of " Qi medicinal herbs" with the confusion of " the different names of the same" and " the different substance of the same names". The most used ethnic groups are Tujia,Qiang and Miao. The main efficacy is clearing heat and detoxification,dispelling wind and removing dampness,etc.,and the main treatment is for injury,rheumatic arthralgia and so on. Names and varieties of " Qi medicinal herbs" among Chinese ethnic groups and folk are standardized and sorted out,which is served to promotethe " Qi medicinal herbs" reasonable protection and utilization of resources,and provide effective reference for exploring the information technology and geographical distribution of ethnic medicine and standardizing clinical medication.

RESUMO

In order to provide guidance for the protection and utilization of resources,quality control and breeding of improved varieties,we compared the main phenotypic characters and quality of wild and transplanted Paris polyphylla var. yunnanensis collected from different producing areas. Seven phenotypic characters of 33 samples of P. polyphylla var. yunnanensis collected from Yunnan,Guizhou and Sichuan were determined by conventional methods,and the principal component analysis and cluster analysis were used to analyze the diversity of the samples. The parissaponin( polyphyllin Ⅰ,Ⅱ,Ⅵ,Ⅶ) content of the samples were detected by HPLC,and analyzed by cluster analysis. Correlation analysis of the phenotypic characters and the parissaponin content was performed. There were significant differences in seven phenotypic characters between wild and transplanted samples of P. polyphylla var. yunnanensis from different habitats,with high phenotypic diversity and abundant genetic variation. The results of principal component analysis showed that leaf shape index was the main factor of morphological variation of P. polyphylla var. yunnanensis. Cluster analysis showed that the phenotypic characters of wild and transplanted P. polyphylla var. yunnanensis could not be completely separated. The content of saponins in wild and transplanted samples from different habitats was quite different. Saponins content of 93. 94% samples met the criterion of Chinese Pharmacopoeia 2015 edition,and the overall quality was relatively steady. The results of independent sample t-test showed that there was no significant difference of all the active ingredient between wild and transplanted samples,and it couldn't be used to distinguish between wild and transplanted samples. It is the same as the results of cluster analysis. The results of correlation analysis showed that the phenotypic traits of P. polyphylla var. yunnanensis were correlated with its medicine quality,and the total content of saponins was positively correlated with leaf length and leaf shape index( r = 0. 389,0. 441; P<0. 05). Yunnan,Guizhou and Sichuan are suitable for the growth of P. polyphylla var. yunnanensis. And the transplaned P. polyphylla var. yunnanensis can be used as the same as the wild ones completely. The results provide reference for the protection and selective breeding of P. polyphylla var. yunnanensis.

RESUMO

Flavonoids are a group of secondary metabolites found in plants. They have many pharmacological functions and play an important role in Chinese sumac( Rhus chinensis),which is a well-known traditional Chinese medicinal plant. Chalcone isomerase( CHI,EC 5. 5. 1. 6) is one of the key enzymes in the flavonoids biosynthesis pathway. In this paper,the full-length c DNA sequence encoding the chalcone isomerase from R. chinensis( designated as Rc CHI) was cloned by RT-PCR and rapid-amplification of c DNA Ends( RACE). The Rc CHI c DNA sequence was 1 058 bp and the open reading frame( ORF) was 738 bp. The ORF predicted to encode a 245-amino acid polypeptide. Rc CHI gene contained an intron and two exons. The sequence alignments revealed Rc CHI shared47. 1%-71. 6% identity with the homologues in other plants. Real-time PCR analysis showed that the total flavonoid levels were positively correlated with tissue-specific expressions of Rc CHI mRNA in different tissues. The recombinant protein was successfully expressed in an Escherichia coli strain with the p GEX-6 P-1 vector. In this paper,the CHI gene was cloned and characterized in the family of Anacardiaceae and will help us to obtain better knowledge of the flavonoids biosynthesis of the flavonoid compounds in R. chinensis.

RESUMO

As a treasure of traditional Chinese medicine culture,Dao-di herbs are famous for their high quality and good effect.However,traditional characteristics of Dao-di herbs and their producing areas are mostly confined to qualitative description,lacking objective evaluation indicators. Numerical taxonomy,which uses mathematical methods to improve the research of taxonomy from qualitative description to quantitative comprehensive analysis,is objective and accurate,so is widely used in the field of biology and medicine.This paper reviews the concept and main research fields of numerical taxonomy,and summarizes its application status and development prospects in the study of Dao-di herbs and characteristics of production areas,in order to lay the foundation for the objectification and standardization of Dao-di herbs.

RESUMO

Objetivo: Identificar as plantas utilizadas com fins terapêuticos por usuários de uma unidade pré-hospitalar pública do município de Campos dos Goytacazes/RJ, os modos de preparo e uso, e o conhecimento deles sobre às propriedades terapêuticas, mecanismos de ação e indicação das plantas que utilizam. Métodos: Pesquisa descritiva, exploratória e qualitativa, operacionalizada por dez entrevistas semiestruturadas em abril de 2016, cujos dados foram tratados por análise temática. Resultados: Foram citadas 40 plantas, sendo a mais frequente a erva cidreira (Lippia alba), utilizada como calmante. A principal forma de obtenção das plantas é por meio de cultivo próprio; e o chá, preparado por infusão ou decocção, a principal forma de consumo. Foram citados malefícios associados ao uso da arnica (Solidago chilensis). Conclusão: Verificou-se que a maior parte das plantas utilizadas é de procedência regional, cujo conhecimento de uso foi adquirido por mães e avós


Objective: The study's purpose has been to identify the plants used for therapeutic purposes by users of a public pre-hospital unit in the Campos dos Goytacazes city, Rio de Janeiro State. Furthermore, to identify the methods of preparation and use, and their knowledge about the therapeutic properties, mechanisms of action and indication of the plants they use. Methods: It is a descriptive-exploratory research with a qualitative approach, which was performed through ten semi-structured interviews in April 2016, whose data were processed by thematic analysis. Results: 40 plants were mentioned, the most frequent being the lemongrass (Lippia alba) that was used as a soothing medicine; the main way of obtaining the plants is by means of own cultivation; and the tea, prepared by infusion or decoction, the main form of consumption. Unpleasant effects associated with the use of bush arnica (Solidago chilensis) were mentioned. Conclusion: It was verified that most of the plants used are of regional origin, whose knowledge of use was acquired through their relatives

RESUMO

In searching for alternatives to traditional chemical medicines, including feed antibiotics, scientists around the world are developing a new generation of medicines, phytobiotics. This work was aimed at studying the phytobiotics (pharmaceutical substances) production technology using the method of low-temperature vacuum water-ethanol extraction of Siberian medicinal plants, followed by low-temperature vacuum drying and determination of the main biologically active substances that had the required pharmacological effect on the organisms of farm animals and poultry. The objects of the study in this work were Siberian medicinal plants and ready phytobiotics (pharmaceutical substances). The article describes the technological conditions for obtaining pharmaceutical substances and their properties concerning the content of biologically active substances. It has been found that for obtaining pharmaceutical substances, extraction should be performed in three stages: two water extractions and ethanol- water extraction. The article provides a list of medicinal plants and the amounts of biologically active substances that ensure certain pharmacological effects on the set of economically useful qualities in farm animals and poultry and contained in phytobiotics (pharmaceutical substances) based on extracts from medicinal plants.
