Abstract
Molecular dereplication and drug-like discovery are important tools for exploring the chemical profile of metabolites in a complex mixture. In order to establish a workflow for discovering novel acetylcholinesterase (AChE) ligands, we performed the chemical study of Myrsine guianensis (Aubl.) Kuntze (Primulaceae). To carry out the bioprospection, nine extracts were obtained from different parts of the plant. Through the dereplication approaches, seventeen metabolites were annotated. In order to confirm the putative inferences, a HPLC preparative method was developed to isolate three known myrsinoic acids, A(1), B(2) and C(3). Along with, we are reporting the obtention of two new congeners, G(5) and H(6), which their structures were elucidated by NMR and HRMS data. Besides that, two extracts were submitted to affinity assays to accelerate the discovery of AChE ligands. Desorbates were analyzed through LC-HRMS for calculating the affinity ratio (AR). Thus, (1) presented AR = 4.59, therefore was considered a potential ligand.

Abstract
L-Cysteine (Cys) is a non-essential sulfur-containing amino acid, crucial for protein synthesis, detoxification, and several metabolic functions. Cys is widely used in the agricultural, food, cosmetic, and pharmaceutical industries. So, a suitable sensitive and selective sensing approach is of great interest, and a low-cost sensor would be necessary. This article presents silver nanoparticles (EuAgNPs) synthesized by a green synthesis method using Eugenia uniflora L. extracts and photoreduction. The nanoparticles were characterized by UV/VIS, transmission electron microscopy, high-performance liquid chromatography (HPLC), FTIR, and Zeta potential. With the addition of Cys in the EuAgNPs solution, the terminal thiol part of L-cysteine binds on the surface of nanoparticles through Ag-S bond. The EuAgNPs and CysAgNPs coexist until flavonoids bound the amino group of Cys, enhancing the red color of solutions. The EuAgNPs provided selectivity to detect Cys among other amino acids, and its detection limit was found to be 3.8 nM. The sensor has the advantages of low-cost synthesis, fast response, high selectivity, and sensitivity.

Abstract
Ayahuasca is a psychoactive brew from the decoction of different Amazonian plants, traditionally used in several cultures, religions, and rituals. Scientific studies with ayahuasca are rapidly increasing due to its subjective effects and therapeutic potential. Although ayahuasca is traditionally used in its liquid presentation, lyophilized (freeze-dried) ayahuasca is often used in scientific experimentation settings. However, there is no standard process or guideline to freeze-dry ayahuasca nor comparison of the chemical profile between the liquid and freeze-dried presentations. Therefore, we describe a reproducible five-day protocol for ayahuasca lyophilization with alkaloids quantification by liquid chromatography coupled to tandem mass spectrometry of both the liquid and the final freeze-dried ayahuasca. By the end of the protocol, approximately 295 g of freeze-dried extract with similar alkaloids concentration were obtained from two liters of ayahuasca (dry matter: 14.75 %). The final extract was stored for three years inside a vacuum desiccator (approximately 6°C) with its texture quality preserved. Further studies should address the impact of different storage conditions and the lyophilization on the alkaloids' quantity of the freeze-dried ayahuasca, especially the use of heat in regards to the β-carbolines.

Abstract
INTRODUCTION Ethnobotanical studies that include participatory methods aim to engage residents in different steps to promote the strengthening and perpetuation of local culture, and empowerment in making decisions about the use of available environmental resources. Thus, the aim of this project was to perform an ethnobotanical survey based on traditional knowledge of medicinal plants with the active participation of residents living in Bairro do Cambury, Ubatuba, São Paulo State, Brazil. MATERIALS AND METHODS During meetings held between the researchers and community members, locally used plants were regarded as an important means for preserving local knowledge for future generations. Some residents showed interest in participating as local partners, and training courses for collecting ethnobotanical data were offered. Local partners and researchers from São Paulo Federal University (Universidade Federal de São Paulo) utilized ethnobotanical methods to select and interview the specialists in medicinal plants for 80 days between 2016 and 2018. Data on plant use were recorded, and plants were collected and deposited in two herbaria. Furthermore, participant observation and fieldwork diaries were used by the researchers, aiding the data analysis. RESULTS Three local partners participated in objective definitions, data collection, analysis and publication. Nine local specialists were interviewed by the local partners and indicated the use of 82 plant species in 90 recipes for 55 therapeutic uses. These uses were grouped into 12 categories. In addition, a video and booklet were created. CONCLUSIONS Data obtained during participatory research show that training local communities in the registration of their own knowledge is feasible and necessary since they register knowledge based on local perceptions, as well as valuing knowledge and approaching the current discussion about intellectual property is a global concern.

Abstract
BACKGROUND Although multiple studies advocate the advantages of participatory research approaches for ethnoscience, few provide solid contributions from case studies that involve residents in all of the project phases. We present a case study of a participatory approach whose aim is to register ethnobotanical knowledge on the use of plants in two quilombola communities (maroon communities), an important biodiversity hotspot in the Atlantic Forest, Southeast Brazil. Our aim is to provide tools that will empower decision-making related to sustainable use and management among residents. METHODS In phase I, the objectives and activities were defined in meetings with residents to carry out ethnobotanical surveys between two quilombola communities-the Quilombo da Fazenda (QF) and Quilombo do Cambury (QC). In phase II, we offered community partners training courses on how to collect plants and ethnobotanical data. In coordination with the university team and using ethnobotanical methods, community partners interviewed specialists on plants and their uses. In phase III, using the participatory mapping method, residents indicated plot locations and collected plants to calculate the Conservation Priority Index for native species recorded in phase II. RESULTS In 178 days of fieldwork, two community partners from the QF and three from the QC selected 8 and 11 respondents who reported 175 and 195 plant species, respectively, corresponding to 9 ethnobotanical categories. Based on requests from the local community, booklets and videos with these data were collaboratively produced. A large percentage of species were found to be of great conservation priority-82.1% in the QC and 62.5% in the QF. Virola bicuhyba, Cedrela fissilis, Plinia edulis, and Tabebuia cassinoides are the species most at risk and will be the focus of phase IV, when a participatory management plan will be carried out. Additionally, we present both challenges and opportunities with the hope that others can learn from our successes and failures. CONCLUSIONS Our experience shows that it is possible to train community members who wish to document their knowledge to support the process of ensuring that local knowledge is highly regarded, further ensuring its perpetuation. In this context, the project may be of great interest to development programs in promoting community-based management strategies for useful plants.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Participatory research can help to broaden the understanding of medical systems and beliefs of traditional communities. An ethnopharmacological survey in collaboration with local people focused on plants used in quilombos located in Southeast Region in Brazil identified cultural factors that influence plant and recipe choice. AIM OF THE STUDY To investigate the factors related to the therapeutic efficiency of medicinal plants from the perspective of Quilombo da Fazenda residents. MATERIALS AND METHODS University researchers collaborated with community residents for both aims and methods of the study. The local partners were trained in the gathering of ethnopharmacological data and then selected and interviewed the residents considered experts on the use of medicinal plants. Data on the use of each species were supported by voucher specimens collected by the local partners and university researchers. Participant observations and field diaries by the university researchers supplemented the data. RESULTS Eight interviewees mentioned 92 medicinal species with 60 therapeutic uses, applied in 208 recipes or remedies. Asteraceae (13 species), Lamiaceae (5) and Urticaceae (5) contributed most medicinal plant species. Of the 12 etic categories of use, the circulatory system category had the highest number of plants mentioned. Decoction was the most commonly used preparation method (66.8%), and most remedies were administered orally (76.4%). Eighty-six recipes included more than one plant species and/or the addition of other components, such as sugar, salt or animal products. Several cultural factors influence medicinal plant use. Popular beliefs on the quality of blood or the humoral properties of plants and illnesses, characteristics of the plants and other factors determine which plant is used and why. CONCLUSIONS The participatory method identified a large number of factors that influence medicinal plant use: the patient's blood type; the condition of the plant and the disease (hot-cold system); the route of administration and dosage; the preventive uses of the plants; and the influence of other factors, such as the sun, the moon and dew. The participatory approach is useful for gaining insight on the decision processes of medicinal plant use in traditional societies, and also for those communities wanting to document their knowledge with or without the participation of the academy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE For innumerous clinical cases related to women's health and precarious medical care in developing countries, a large repertoire of plants have been used as popular medicines in order to fill this gap, which in a certain way creates health risks to users, since pharmacological and toxicological tests are still insufficient to guarantee their efficacy and safety. Besides therapeutic use, abortive plants are broadly used in countries where abortion is prohibited, increasing that risk even more. In this way, ethnopharmacological studies that register plants used for women's health can contribute not only to the selection of potential bioactives, enriching the repertoire of drugs available to females, above all in public health systems, but also questioning the safety of products that are used without prescription. AIMS AND OBJECTIVES This review aims at determining plants applied by Brazilian cultures in the treatment of conditions related to maternity, menstrual cycle and other women's health particularities, and to supplement the lack of epidemiological data available to assess the health of indigenous, rural and other populations of Brazilian women. MATERIALS AND METHODS A literature review was conducted of the collection at the Ethnobotanical and Ethnopharmacological Center of the Federal University of São Paulo (period covered: 1965 to 2012). All of the 343 articles were consulted and 31 articles mentioning therapeutic uses of interest were selected. Relevant information was extracted to compose Table 1 - Maternity, Table 2 - Menstrual Cycle and Table 3 - Other Conditions. Data was statistically analyzed in order to generate the discussion about plants used in healing contexts by different Brazilian ethnicities. A bibliographic review was performed using the Scopus database to collect the following information about the most cited plants: ethnobotany/ethnopharmacology of non-Brazilian cultures for women's health conditions, pharmacology, toxicology, and adverse reactions. RESULTS A total of 319 species were cited for 22 indications related to women's health. Ninety-seven species were indicated for conditions related to maternity, 94 to the menstrual cycle and 232 to others. The same species could be present in more than one of these three categories. The most cited family was Fabaceae (13.5%), and the species were Ruta graveolens L. (1.76%) and Strychnos pseudoquina A. St.-Hil (1.76%). The most frequent part utilized, mode of preparation and route of administration were leaves (2.0%), tea (73.38%) and oral (87. 2%), respectively. The indications that showed the highest number of species were: to treat venereal diseases (69 species), abortive (54) and anti-inflammatory for the ovaries and/or uterus (54). According to our bibliographic survey, among the 19 most indicated species in this review, only four are also used by non-Brazilian cultures for conditions related to women's health; 25% of them were pharmacologically investigated and it was possible to validate their ethnopharmacological/ethnobotanical use, 10.5% have presented well-described adverse reactions and for 42.1% of these species toxicological studies were performed. CONCLUSION The survey raised important data about plants implemented in healing related to women's health conditions by Brazilian cultures and their practices. The compilation presented in this study enables the realization of further investigation regarding the development of herbal medicines and contributes to the incrementation of policies focused on these cultures. Further phytochemical, pharmacological and toxicological studies should be conducted, which will allow the discovery of pharmacological properties, bioactive constituents, and moreover, adequate posology, manner of use and adverse events.
