RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: In the quilombola communities of the municipality of Oriximiná (Pará State, Brazil), Protium spp. (Burseraceae) oleoresins are distinguished in black and white pitch. White pitch oleoresins may be superior to black pitch in terms of quality, but the criteria used for their differentiation are fairly subjective. AIM OF THE STUDY: This study was designed to provide a scientific rationale for the traditional differentiation of black and white pitch oleoresins based on their non-volatile fraction. MATERIALS AND METHODS: Black and white pitch oleoresin samples collected in quilombola territories in Oriximiná were analysed by GC-EI-MS and UPLC-APCI-MS. The feasibility of EI and APCI mass spectrometry-based pattern recognition methods PLS-DA and Random Forest Analysis (RFA) for black and white pitch oleoresins differentiation was demonstrated. RESULTS: The UPLC-APCI-MS method allowed the separation of 43 triterpenoids. Assessment of the triterpenoid fingerprints by GC-EI-MS led to the tentative identification of ursa-9(11),12-dien-3-ol as a potential marker for black pitch oleoresins. PLS-DA and RFA applied to the APCI-MS and EI-MS data gave good models for black and white pitch oleoresins classification. The most important ions for the classifications of black pitch oleoresins by APCI-MS/PLS-DA and APCI-MS/RFA likely represented triterpenoid acids. CONCLUSIONS: The triterpenoid pattern differs between black and white pitch oleoresins. The characteristic presence of ursa-9(11),12-dien-3-ol and triterpenoids acids in black pitch oleoresins, along with other field observations, suggest that black pitch oleoresins are actually aged white pitch oleoresins.

RESUMO Garrafadas, em geral, são combinações de plantas medicinais veiculadas em bebidas alcoólicas, utilizadas com diversas finalidades na medicina popular. O presente estudo apresentou um panorama das garrafadas, relacionando-as à regulamentação sanitária no Brasil. Para tal, foi realizada uma pesquisa descritiva exploratória das garrafadas divulgadas na internet, bem como das notificações de queixas técnicas e eventos adversos junto à Agência Nacional de Vigilância Sanitária (Anvisa). A pesquisa mostrou que as garrafadas são amplamente divulgadas na internet. Concluiu-se que as garrafadas são comercializadas em todo País, sem nenhuma barreira, sendo órfãs de regulamentação sanitária específica, mas legitimadas pela cultura popular.
ABSTRACT Garrafadas, in general, are combinations of medicinal plants conveyed in alcoholic beverages, used for a variety of purposes in popular medicine. The present study presented an overview of the garrafadas, relating them to sanitary legislation in Brazil. For this, an exploratory descriptive research was carried out on garrafadas advertised on the internet, as well as notifications of technical complaints and adverse events with Anvisa (National Agency of Sanitary Inspection). The research has shown that garrafadas are widely spread on the internet. It was concluded that garrafadas are commercialized throughout the Country, without any barriers, being orphaned by specific sanitary legislation, but legitimized by popular culture.
