Abstract
Carapa guianensis species belongs to the Meliaceae family and, in the Brazilian Amazon, it has great importance in folk medicine, mainly because the oil extracted from its seeds presents varied biological activities. Thus, the present work aimed to analyze, by gas phase chromatography coupled to mass spectrometry (GC/MS), the chemical composition of manually extracted andiroba oil, from Mamangal community, located in Igarapé-Miri, Pará, Brazil. As results, 99.63% of the constituents of the oil sample were identified and quantified from which the main components were oleic, palmitic, stearic, and linoleic acids. The manual oil extraction from andiroba seeds in the Mamangal community is sustainable and economically viable. Due to the high content of saturated and unsaturated fatty acids C. guianensis oil can be considered interesting useful for pharmaceutical and cosmetic industries. Indeed, the unsaturated fatty acids represented 57.5% of the oil constituents, among which the essential ones stand out, as they have great applicability in healing drugs formulation.
Highlights
Species of the family Meliaceae (Sapindales) shows great commercial value such as Cedrela fissilis, Cedrela odorata, Swietenia macrophylla, and some of them can be used in landscaping (Guarea Guidonia and Melia azadarach), or in environmental recovery (Trichilia claussenii), and in folk medicine (Carapa guianensis, Carapa procera, and Azadirachta indica)

Fatty acid methyl esters were analyzed by Gas Chromatography/Mass Spectrometry (GC/MS), as described by Silva et al (2009) [20] and Silva (2018) [21], which was adapted in a Shimadzu QP Plus-2010 system, under the following conditions: capillary silica column Rtx-5MS (30 m x 0.25 mm; 0.25 μm film thickness); oven temperature programming starting in 100oC (5 min) and with a gradient of 4oC/min up to 260oC (20 min); injector temperature of 250oC; carrier gas: helium; split-type injection of 1.0 μl of the sample
Summary
Species of the family Meliaceae (Sapindales) shows great commercial value such as Cedrela fissilis, Cedrela odorata, Swietenia macrophylla, and some of them can be used in landscaping (Guarea Guidonia and Melia azadarach), or in environmental recovery (Trichilia claussenii), and in folk medicine (Carapa guianensis, Carapa procera, and Azadirachta indica). Because of its broad biological activity C. guianensis oil is widely consumed in folk medicine, with medicinal properties such as: analgesic [4], anti-bacterial [5,6,7], anti-inflammatory [8], anti-fungal [9], anti-allergic [10], anti-malarial [11], antioxidant [12], and healing properties. The various benefits to human health attributed to andiroba oil reinforce the importance of develop studies concerning to its chemical composition In this sense, the present study aimed to analyze, by gas chromatography coupled to mass spectrometry (GC/MS), the chemical composition of andiroba oil, manually extracted in the Mamangal community, located in Igarapé-Miri, Pará
