thnopharmacological relevance:In thequilombolacommunities of the municipality of Oriximiná (Pará State,Brazil),Protiumspp. (Burseraceae) oleoresins are distinguished in black and white pitch. White pitch oleoresinsmay be superior to black pitch in terms of quality, but the criteria used for their differentiation are fairlysubjective.Aim of the study:This study was designed to provide a scientific rationale for the traditional differentiation ofblack and white pitch oleoresins based on their non-volatile fraction.Materials and methods:Black and white pitch oleoresin samples collected inquilombolaterritories in Oriximináwere analysed by GC-EI-MS and UPLC-APCI-MS. The feasibility of EI and APCI mass spectrometry-based patternrecognition methods PLS-DA and Random Forest Analysis (RFA) for black and white pitch oleoresins differ-entiation was demonstrated.Results:The UPLC-APCI-MS method allowed the separation of 43 triterpenoids. Assessment of the triterpenoidfingerprints by GC-EI-MS led to the tentative identification of ursa-9(11),12-dien-3-ol as a potential marker forblack pitch oleoresins. PLS-DA and RFA applied to the APCI-MS and EI-MS data gave good models for black andwhite pitch oleoresins classification. The most important ions for the classifications of black pitch oleoresins byAPCI-MS/PLS-DA and APCI-MS/RFA likely represented triterpenoid acids.Conclusions:The triterpenoid pattern differs between black and white pitch oleoresins. The characteristic pre-sence of ursa-9(11),12-dien-3-ol and triterpenoids acids in black pitch oleoresins, along with otherfield ob-servations, suggest that black pitch oleoresins are actually aged white pitch oleoresins.
