Evidence for the efficacy of anti-inflammatory plants used in Brazilian traditional medicine with ethnopharmacological relevance. JOURNAL OF ETHNOPHARMACOLOGY 2024; 329:118137. [PMID: 38574778 DOI: 10.1016/j.jep.2024.118137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 03/27/2024] [Accepted: 03/29/2024] [Indexed: 04/06/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE When exacerbated, inflammatory processes can culminate in physical and emotional disorders and, if not stopped, can be lethal. The high prevalence of inflammation has become a public health problem, and the need for new drugs to treat this pathology is imminent. The use of medicinal plants has emerged as an alternative, and a survey of data that corroborates its application in inflammatory diseases is the starting point. Furthermore, Brazil harbors a megadiversity, and the traditional use of plants is relevant and needs to be preserved and carefully explored for the discovery of new medicines. AIM OF THE STUDY This review sought to survey the medicinal plants traditionally used in Brazil for the treatment of inflammatory processes and to perform, in an integrative way, a data survey of these species and analysis of their phytochemical, pharmacological, and molecular approaches. MATERIALS AND METHODS Brazilian plants that are traditionally used for inflammation (ophthalmia, throat inflammation, orchitis, urinary tract inflammation, ear inflammation, and inflammation in general) are listed in the DATAPLAMT database. This database contains information on approximately 3400 native plants used by Brazilians, which were registered in specific documents produced until 1950. These inflammatory disorders were searched in scientific databases (PubMed/Medline, Scopus, Web of Science, Lilacs, Scielo, Virtual Health Library), with standardization of DECS/MESH descriptors for inflammation in English, Spanish, French, and Portuguese, without chronological limitations. For the inclusion criteria, all articles had to be of the evaluated plant species, without association of synthesized substances, and full articles free available in any of the four languages searched. Duplicated articles and those that were not freely available were excluded. RESULTS A total of 126 species were identified, culminating in 6181 articles in the search. After evaluation of the inclusion criteria, 172 articles representing 40 different species and 38 families were included in the study. Comparison of reproducibility in intra-species results became difficult because of the large number of extraction solvents tested and the wide diversity of evaluation models used. Although the number of in vitro and in vivo evaluations was high, only one clinical study was found (Abrus precatorius). In the phytochemical analyses, more than 225 compounds, mostly phenolic compounds, were identified. CONCLUSION This review allowed the grouping of preclinical and clinical studies of several Brazilian species traditionally used for the treatment of many types of inflammation, corroborating new searches for their pharmacological properties as a way to aid public health. Furthermore, the large number of plants that have not yet been studied has encouraged new research to revive traditional knowledge.

JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2021; 17:70. [PMID: 34924006 PMCID: PMC8684639 DOI: 10.1186/s13002-021-00496-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 11/25/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Open and public markets are the main providers of medicinal plants in urban environments. The present study evaluated the medicinal plants sold in public markets in different municipalities in the mesoregions of the state of Paraíba, northeast of Brazil, and the possible variations in the supply of these plants in the markets over the course of a year. METHODS Interviews with medicinal plant traders were conducted in four mesoregions of different climatic and phytophysiognomic characteristics (ranging from Caatinga to Atlantic Forest). The versatility of the species sold was elucidated using the relative importance (RI) index, and the set of species sold by each informant in each mesoregion was compared with each other by one-way Anosim and by the analysis of main coordinates. RESULTS Thirty-five plant traders identified 163 medicinal plant species (151 genders and 76 families) and more 17 non identified species. The most frequent families were Fabaceae (19 species), Asteraceae (12), Lamiaceae (11), and Myrtaceae (6). Punica granatum, Zingiber officinale, and Myracrodruon urundeuva were the species with the highest RI. The analysis of similarity showed distinct differences between the Sertão and all other mesoregions. The Agreste, an ecotone area, was also the area where more species of other regions was found. The absence of 88 species in at least one of the trading locations at some stage of the fieldwork was recorded. CONCLUSIONS The presence and absence of the commercialized species do not seem to be related to the period of the year or the mesoregion. There were differences in the inventory of plants commercialized in markets in recent years. We identified an intermediate zone of knowledge and use of species commercialized between the studied localities.

Advanced Chemophenetic Analysis of Essential Oil from Leaves of Piper gaudichaudianum Kunth (Piperaceae) Using a New Reduction-Oxidation Index to Explore Seasonal and Circadian Rhythms. PLANTS 2021; 10:plants10102116. [PMID: 34685925 PMCID: PMC8540104 DOI: 10.3390/plants10102116] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 09/26/2021] [Accepted: 09/28/2021] [Indexed: 11/16/2022]
Abstract
The aromatic species Piper gaudichaudianum Kunth (Piperaceae) is widely used in Brazil for medicinal and ritualistic applications. In the current study, chemophenetic patterns were realized across season and circadian rhythm based on the chemical profile of essential oils (EOs) from leaves. Hydrodistilled essential oils were analyzed by GC-MS and GC-FID, and a new calculation of metabolite oxidation level, averaged for each individual molecule component of the EO, was used to explore the patterns of metabolism/biosynthesis. This new index used an intermediate calculation, the 'weighted average redox standard' (SRO), to enable a value for mixtures of metabolites to be generated, the 'general mixture redox index' (GMOR). The indices were subjected to a proof-of-concept approach by making comparison to outcomes from multivariate analyses, i.e., PCA and HCA. Chemical analysis demonstrated that the essential oils were dominated by sesquiterpenes, constructed of 15 classes of compound (C-skeletons), and 4 C-skeletons were recognized in the monoterpene group, giving a total of 19. The variation of chemical profiles was distinct at different phenological stages, but stronger chemical variation was evident between day and night as compared to season. Furthermore, due to comprehensive sampling across different regions, nine chemotypes were recognized, including those previously reported. The SRO and GMRO indices demonstrate that phenological variation of chemistry is mainly an outcome of redox fluctuations in terpene biosynthesis, changing from day to night. These indices also corroborate that chemical diversity is increased with oxidative metabolism. Lastly, the current study demonstrates pronounced phenotypic plasticity in P. gaudichaudianum, which makes it a suitable candidate to help further our understanding of chemophenetics and chemical ecology.

Paving New Roads Towards Biodiversity-Based Drug Development in Brazil: Lessons from the Past and Future Perspectives. ACTA ACUST UNITED AC 2021; 31:505-518. [PMID: 34548709 PMCID: PMC8447804 DOI: 10.1007/s43450-021-00181-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 08/25/2021] [Indexed: 11/29/2022]
Abstract
Although Brazil gathers two fundamental features to occupy a leading position on the development of biodiversity-based medicines, the largest flora on earth and a broad tradition on the use of medicinal plants, the number of products derived from the national genetic heritage is so far modest, either as single drugs or as herbal medicines. This article highlights some aspects that may have contributed to the low rates of success and proposes new insights for innovation. We initially approach the use of medicinal plants in Brazil, molded by its ethnic diversity, and the development of the local pharmaceutical industry. A discussion of some governmental initiatives to support plant-based drug development is then presented. Employing the economic concept of “middle-income trap,” we further propose that Brazil is stuck in a “middle-level science trap,” since the increase in the number of scientific publications that launched the country to an intermediate publishing position has not been translated into drug development. Two new approaches to escape from this trap are presented, which may result in innovative drug development. The first is based on the exploitation of the antifragility properties of herbal products aiming to investigate non-canonical pharmacodynamics mechanisms of action, aligned with the concepts of system biology. The second is the manufacture of herbal products based on the circular economy principles, including the use of byproducts for the development of new therapeutical agents. The adoption of these strategies may result in innovative phytomedicines, with global competitiveness.

Abstract
Traditional knowledge (TK) of medicinal plants in cities has been poorly studied across different inhabitants' socioeconomic sectors. We studied the small city of Chachapoyas (~34,000 inhabitants) in the northern Peruvian Andes. We divided the city into three areas according to the socio-economic characteristics of its inhabitants: city center (high), intermediate area (medium), and city periphery (low). We gathered information with 450 participants through semi-structured interviews. Participants of the city periphery showed a higher TK of medicinal plants than participants of the intermediate area, and the latter showed a higher TK than participants of the city center. The acquisition of medicinal plants was mainly through their purchase in markets across the three areas, although it was particularly relevant in the city center (94%). Participants of all socioeconomic levels widely used the same medicinal plants for similar purposes in Chachapoyas, which is likely based on a common Andean culture that unites their TK. However, participants with the lowest socioeconomic level knew and used more plants for different medicinal uses, indicating the necessity of these plants for their livelihoods. City markets with specialized stores that commercialize medicinal plants are key to preserve the good health of poor and rich people living in Andean cities and societies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Quassia amara L. recently came into the spotlight in French Guiana, when it became the object of a biopiracy claim. Due to the numerous use records throughout the Guiana shield, at least since the 18th century, a thorough investigation of its origin seemed relevant and timely. In the light of the Convention on Biological Diversity (CBD) and the Nagoya protocol, questions about the origin of local knowledge are important to debate. AIM OF THE STUDY Defining cultural biogeography as the dynamics through space and time of biocultural complexes, we used this theoretical framework to shed light on the complex biogeographical and cultural history of Q. amara. We explored in particular the possible transfer of medicinal knowledge on an Old World species to a botanically related New World one by enslaved Africans in Suriname. MATERIALS AND METHODS Historical and contemporary literature research was performed by means of digitized manuscripts, archives and databases from the 17th to the 21st century. We retrieved data from digitized herbarium vouchers in herbaria of the Botanic Garden Meise (Belgium); Naturalis Biodiversity Center (the Netherlands); Missouri Botanical Garden, the Smithsonian National Museum of Natural History, the Field Museum (USA); Royal Botanic Gardens Kew (UK); the IRD Herbarium, French Guiana and the Museum National d'Histoire Naturelle (France). Vernacular names were retrieved from literature and herbarium specimens and compared to verify the origin of Quassia amara and its uses. RESULTS Our exploration of digitized herbarium vouchers resulted in 1287 records, of which 661 were Q. amara and 636 were Q. africana. We observed that the destiny of this species, over at least 300 years, interweaves politics, economy, culture and medicine in a very complex way. Quassia amara's uses are difficult to attribute to specific cultural groups: the species is widely distributed in Central and South America, where it is popular among many ethnic groups. The species spread from Central to South America during the early 18th century due to political and economic reasons. This migration possibly resulted from simultaneous migration by religious orders (Jesuits) from Central America to northern South America and by Carib-speaking Amerindians (from northern South America to Suriname). Subsequently, through colonial trade networks, Q. amara spread to the rest of the world. The absence of African-derived local names in the Guiana shield suggests that Q. africana was not sufficiently familiar to enslaved Africans in the region that they preserved its names and transferred the associated medicinal knowledge to Q. amara. CONCLUSIONS Cultural biogeography has proven an interesting concept to reconstruct the dynamics of biocultural interactions through space and time, while herbarium databases have shown to be useful to decipher evolution of local plant knowledge. Tracing the origin of a knowledge is nevertheless a complex adventure that deserves time and interdisciplinary studies.

Abstract
BACKGROUND In spite of an increasing number of ethnobotanical market surveys in the past decades, few studies compare changes in plant species trade over time. The open-air market Ver-o-Peso (VOP) in Belém, located near the mouth of the Amazon River in the state of Pará, Brazil, is known for its wide variety of medicinal plants. A survey of VOP was published in 1984, but it remains unknown to what extent its botanical composition changed over 34 years. Furthermore, in northern Brazil, little attention has been given to the origins of the vernacular names of these plants. Our aim is to give an up-to-date overview of the VOP medicinal plant market, concentrating on changes in species composition and vernacular names over time. METHODS We collected medicinal plants and vernacular names at VOP in August 2018. We identified most plants at the Museo Paraense Emilio Goeldi Herbarium, where we also deposited vouchers and specimen labels. We compared our species composition data to the 1984 inventory by Van den Berg. Furthermore, we investigated the etymologies of the vernacular plant names. RESULTS We recorded 155 plant specimens and 165 corresponding vernacular names, and collected 146 specimens from the medicinal and ritual stalls of VOP reporting 86 species formerly not recorded at this market. Vernacular names had mostly Portuguese roots, followed by Tupi and African ones. We found 30 species also documented in 1984, and vernacular names that overlapped between both surveys were used for the same botanical species or genus, indicating that vernacular names have changed little in the past decades. Lastly, we found 26 more introduced species sold at VOP compared to 1984. CONCLUSIONS Forest degradation and deforestation, prevalence of diseases, and methodological factors may play a role in the differences we found in our survey compared to 1984. Of the plants that did overlap between the two surveys, vernacular names of these plants were hardly different. Lastly, the lingual origins of the vernacular names in our survey and the origins of the plant species reflect the history of the intricate syncretism of medicinal plant practices of indigenous, Afro-Brazilian and European origins in Belém.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 259:112911. [PMID: 32389855 DOI: 10.1016/j.jep.2020.112911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 04/17/2020] [Accepted: 04/22/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Parallelisms between current and historical medicinal practices as described in the seventeenth century treatise Historia Naturalis Brasiliae (HNB) provide us with an overview of traditional plant knowledge transformations. Local markets reflect the actual plant use in urban and rural surroundings, allowing us to trace cross-century similarities of ethnobotanical knowledge. AIMS OF THE STUDY We aim to verify in how far the HNB, created in seventeenth-century northeastern Brazil, correlates with contemporary plant use in the country by comparing the plant knowledge therein with recent plant market surveys at national level. MATERIALS AND METHODS We conducted a literature review on ethnobotanical market surveys in Brazil. We used the retrieved data on plant composition and vernacular names, together with our own fieldwork from the Ver-o-Peso market in Belém, to compare each market repertoire with the useful species in the HNB. We analyzed similarities among markets and the HNB with a Detrended Correspondence Analysis and by creating Venn diagrams. We analyzed the methods of the different markets to check whether they influenced our results. RESULTS Out of the 24 markets reviewed, the greatest similarities with the HNB are seen in northern Brazilian markets, both in plant composition and vernacular names, followed by the northeast. The least overlap is found with markets in the central west and Rio de Janeiro. Most of the shared vernacular names with the HNB belonged to languages of the Tupi linguistic family. CONCLUSION The similarity patterns in floristic composition among Brazilian markets and the HNB indicate the current wider distribution and trade of the species that Marcgrave and Piso described in 1648 in the northeast. Migration of indigenous groups, environmental changes, globalized and homogenous plant trade, and different market survey methods played a role in these results. The HNB is a reference point in time that captures a moment of colonial cultural transformations.

Ricardo LM, Dias BM, Mügge FLB, Leite VV, Brandão MGL. Evidence of traditionality of Brazilian medicinal plants: The case studies of Stryphnodendron adstringens (Mart.) Coville (barbatimão) barks and Copaifera spp. (copaíba) oleoresin in wound healing. JOURNAL OF ETHNOPHARMACOLOGY 2018; 219:319-336. [PMID: 29501844 DOI: 10.1016/j.jep.2018.02.042] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Revised: 02/25/2018] [Accepted: 02/26/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The World Health Organization (WHO) recognizes the potential of plants used in secular traditional medicine and considers this an important source of evidence to assess their effectiveness and safety. Brazil is rich in biodiversity and traditional uses based on the Amerindian culture. However, many processes started with the arrival of the Portuguese in the year 1500. The successive economic cycles, for example, led to destruction of native vegetation and an intense cultural erosion. As a consequence, the information about the use of plants in the past centuries are dispersed and without interpretation. In this study a methodology to evidence the traditionality of Brazilian plants was demonstrated using data about barbatimão barks (Stryphnodendron adstringens (Mart.) Coville - Fabaceae) and Copaiba oleoresin (Copaifera spp. - Fabaceae) in wound healing, was established. MATERIAL AND METHODS Data about use of the plants were recovered from bibliography published between 1576 and 2011. The books (101) were classified using weights, considering the date of publication and the source of Information. Older books that describe primary information received weight 10, while books written more recently and with secondary information received weight 0.4. A score for each category of medicinal use was calculated based on the books weights and the frequency of citation. A review about the current use of both plants was also performed from ethnobotanical studies published in journals. RESULTS AND DISCUSSION The traditional secular use of barks of barbatimão and oleoresin of copaiba to treat wounds was confirmed based on the historic bibliographic research. The most frequent use of barbatimão in a timeline of 500 years of Brazil's history, was as astringent, whereas for copaíba was as healing of skin and mucosal lesions. The continuous and current use of these plants to treat wounds, confirmed by recent ethnobotanical studies, is an indicative of the resilience of these remedies and their effectiveness. CONCLUSION The use of preparations containing barbatimão barks and copaiba oleoresin can be considered effective in the treatment of wounds. Nonetheless, it is necessary to improve the quality of the formulas as established by WHO.

Abstract
OBJECTIVE The aim of this study was to analyze factors associated with the consumption of medicinal plants by patients being treated with warfarin in a Brazilian anticoagulation clinic and to study the safety of medicinal plant use in patients on warfarin therapy. METHODS The study was performed as an observational cross-sectional analysis. Study participants were outpatients on long-term warfarin therapy for at least 2 months for atrial fibrillation or prosthetic cardiac valves. Interviews were carried out concerning information about the habits of medicinal herb consumption, and logistic regression analysis was performed to identify factors associated with the consumption of herbs. The scientific names of the medicinal plants were identified to search for information on the effects on the hemostasis of the interactions between the medicinal herbs reported and warfarin. RESULTS The mean age of the 273 patients included was 60.8 years; 58.7% were women. Medicinal plants were used by 67% of the participants. No association between demographic and clinical data and the use of medicinal plants was identified. Patients reported a total of 64 different plants, primarily consumed in the form of tea. The plants were mainly used to treat respiratory tract and central nervous system disorders. About 40% of the plants cited have been reported to potentially interfere with the anticoagulation therapy, principally by potentiating the effects of warfarin, which could, increase the risk of bleeding. CONCLUSION The use of medicinal plants was highly common and widespread in patients receiving warfarin as an anticoagulation therapy. Univariate analysis of variables associated with the consumption of herbs showed no statistically significant difference in the consumption of medicinal plants for any of the sociodemographic and clinical data. The medicinal plants that were reportedly consumed by the patients could affect hemostasis. This study reinforces the need for further studies evaluating the habits of patients consuming medicinal plants and their clinical implications, and will help to design strategies to manage the risks associated with warfarin-herbal interactions.

Abstract
This study evaluates the antibacterial activity of the Copaifera duckei Dwyer oleoresin and two isolated compounds [eperu-8(20)-15,18-dioic acid and polyalthic acid] against bacteria involved in primary endodontic infections and dental caries and assesses the cytotoxic effect of these substances against a normal cell line. MIC and MBC assays pointed out the most promising metabolites for further studies on bactericidal kinetics, antibiofilm activity, and synergistic antibacterial action. The oleoresin and polyalthic acid but not eperu-8(20)-15,18-dioic provided encouraging MIC and MBC results at concentrations lower than 100 μg mL−1. The oleoresin and polyalthic acid activities depended on the evaluated strain. A bactericidal effect on Lactobacillus casei (ATCC 11578 and clinical isolate) emerged before 8 h of incubation. For all the tested bacteria, the oleoresin and polyalthic acid inhibited biofilm formation by at least 50%. The oleoresin and polyalthic acid gave the best activity against Actinomyces naeslundii (ATCC 19039) and L. casei (ATCC 11578), respectively. The synergistic assays combining the oleoresin or polyalthic acid with chlorhexidine did not afford interesting results. We examined the cytotoxicity of C. duckei oleoresin, eperu-8(20)-15,18-dioic acid, and polyalthic acid against Chinese hamster lung fibroblasts. The oleoresin and polyalthic acid were cytotoxic at concentrations above 78.1 μg mL−1, whereas eperu-8(20)-15,18-dioic displayed cytotoxicity at concentrations above 312.5 μg mL−1. In conclusion, the oleoresin and polyalthic acid are potential sources of antibacterial agents against bacteria involved in primary endodontic infections and dental caries in both the sessile and the planktonic modes at concentrations that do not cause cytotoxicity.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2017; 2017:1352948. [PMID: 28536641 PMCID: PMC5425840 DOI: 10.1155/2017/1352948] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Revised: 02/11/2017] [Accepted: 03/16/2017] [Indexed: 01/28/2023]
Abstract
In the last two decades, there has been a tremendous increase in the global use of herbal medicinal products (HMPs) due to their claimed health benefits. This has led to increase in their demand and consequently, also, resulted in massive adulteration. This is due to the fact that most of the traditional methods cannot identify closely related species in a process product form. Therefore the urgent need for simple and rapid identification methods resulted in the discovery of a novel technique. DNA barcoding is a process that uses short DNA sequence from the standard genome for species identification. This technique is reliable and is not affected by external factors such as climates, age, or plant part. The difficulties in isolation of DNA of high quality in addition to other factors are among the challenges encountered using the DNA barcoding in the authentication of HMP. These limitations indicated that using DNA barcoding alone may ineffectively authenticate the HMP. Therefore, the combination of DNA barcoding with chromatographic fingerprint, a popular and generally accepted technique for the assessment and quality control of HMP, will offer an efficient solution to effectively evaluate the authenticity and quality consistency of HMP. Detailed and quality information about the main composition of the HMPs will help to ascertain their efficacy and safety as these are very important for quality control.

Abstract
Environmentally friendly botanical larvicides are commonly considered as an alternative to synthetic larvicides against Aedes aegypti Linn. In addition, mosquito resistance to currently used larvicides has motivated research to find new compounds acting via different mechanisms of action, with the goal of controlling the spread of mosquitos. Essential oils have been widely studied for this purpose. This work aims to evaluate the larvicidal potential of Syzygium aromaticum and Citrus sinensis essential oils, either alone or in combination with temephos, on Ae. aegypti populations having different levels of organophosphate resistance. The 50% lethal concentration (LC50) of the essential oils alone and in combination with temephos and the influence of essential oils on vector oviposition were evaluated. The results revealed that essential oils exhibited similar larvicidal activity in resistant populations and susceptible populations. However, S. aromaticum and C. sinensis essential oils in combination with temephos did not decrease resistance profiles. The presence of the evaluated essential oils in oviposition sites significantly decreased the number of eggs compared to sites with tap water. Therefore, the evaluated essential oils are suitable for use in mosquito resistance management, whereas their combinations with temephos are not recommended. Additionally, repellency should be considered during formulation development to avoid mosquito deterrence.

Abstract
Medicinal plants are used throughout the world, and the regulations defining their proper use, such as identification of the correct species and verification of the presence, purity and concentration of the required chemical compounds, are widely recognized. Herbal medicines are made from vegetal drugs, the processed products of medicinal species. These processed materials present a number of challenges in terms of botanical identification, and according to the World Health Organization (WHO), the use of incorrect species is a threat to consumer safety. The samples used in this study consisted of the dried leaves, flowers and roots of 257 samples from 8 distinct species approved by the WHO for the production of medicinal herbs and sold in Brazilian markets. Identification of the samples in this study using DNA barcoding (matK, rbcL and ITS2 regions) revealed that the level of substitutions may be as high as 71%. Using qualitative and quantitative chemical analyses, this study identified situations in which the correct species was being sold, but the chemical compounds were not present. Even more troubling, some samples identified as substitutions using DNA barcoding contained the chemical compounds from the correct species at the minimum required concentration. This last situation may lead to the use of unknown species or species whose safety for human consumption remains unknown. This study concludes that DNA barcoding should be used in a complementary manner for species identification with chemical analyses to detect and quantify the required chemical compounds, thus improving the quality of this class of medicines.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Quina is a popular name originally attributed to Cinchona pubescens Vahl (=Cinchona succirubra) and Cinchona. calisaya Wedd., species native from Peru that have the antimalarial alkaloid quinine. In Brazil, bitter barks substitutes for the Peruvian species began to be used centuries ago, and they still are sold in popular markets. To assess the authenticity and the conditions on which samples of quinas have been commercialized, using the DNA barcode, chemical and biological assays. MATERIALS AND METHODS Starting with 28 samples of barks acquired on a popular market, 23 had their DNA extracted successfully. The regions matK and rbcL were amplified and sequenced for 15 and 23 samples, respectively. Phytochemical analyses were performed by chromatographic methods, and biological essays were done by antimalarial tests in vitro. RESULTS The identified species belonged to six different families, many of them endangered or with no correlation with use in traditional medicine as a Brazilian quina. The absence of typical bitter chemical substances indicated that barks have been collected from other species or from very young trees. The results of biological essays confirm the lack of standardization of the sold materials. CONCLUSION The integrated approaches proved to be efficient to evaluate medicinal plants sold in popular markets and can be useful for promoting their better use and conservation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bitter tasting plant species are used as tonics and have been previously used to treat intermittent fevers in Brazil, the principal symptom of malaria. Many of these species were named quina and were used as substitutes of Cinchona spp., the source of quinine. AIM OF THE STUDY To present data on these bitter species named quina and to discuss their potential as sources of bioactive substances. MATERIALS AND METHODS Data about the plants were obtained from a survey of the literature and documents written by early naturalists and clinical doctors living in the 18th and 19th centuries in Brazil. Correlated pharmacological studies were obtained from different scientific databases. RESULTS A total of 29 species were recorded. The largest number of species belonged to the Rubiaceae family (14), being Remijia ferruginea (A. St.-Hil) DC. the most representative. Strychnos pseudoquina A. St.-Hil. (Loganiaceae), Hortia brasiliana Vand. ex DC. (Rutaceae) and Solanum pseudoquina A. St.-Hil. (Solanaceae) were also frequently mentioned in the historical bibliography. Pharmacological studies have shown the presence of bitter bioactive substances useful to treat digestive disorders and/or with antimalarial activities, in all of the recorded botanic families. CONCLUSION This study shows that several bitter species named quina were used in the past as substitute of Cinchona spp. and studying these plants can lead to the development of new products.
