Characterization of Buriti (Mauritia flexuosa L.) oil by absorption and emission spectroscopies

Abstract

Amostras de óleo obtido do fruto do Buriti (Mauritia flexuosa L.) foram caracterizadas por espectroscopia de absorção e emissão. O espectro de absorção foi obtido no intervalo de 300 a 2000 nm, enquanto o espectro de emissão foi analisado entre 400 e 800 nm, onde observamos várias bandas. Para melhor entender a complexidade destes espectros, também obtivemos os espectros de absorção e emissão dos componentes majoritários do óleo de Buriti. Correlacionando estes dados, apresentamos uma discussão sobre a origem das bandas observadas. Oil samples obtained from Buriti (Mauritia flexuosa L.) palm tree fruits were characterized by absorption and emission spectroscopies. The absorption spectrum was recorded in the range from 300 to 2000 nm, while the emission spectrum was analyzed between 400 and 800 nm, where several bands were observed. To better understand these complex spectra, we recorded both absorption and emission spectra of its major components. By correlating these data, we present a discussion on the possible origin of the bands observed.

Fatty acids profile of pulp and nuts of Brazilian fruits

“…Analyzing the fatty acid profile of the oil extracted from Buriti pulp, Albuquerque et al (2005) found that the oil composition presented high 18:1 (73.3-78.73%) and low 18:2 (2.4-3.93%) contents, which is in accordance with the results obtained in previous studies (ESCRICHE et al, 1999).…”

“…To make sure that they are suitable for commercial use, it is very important to investigate their chemical and physical properties (ESCRICHE et al, 1999;BENJELLOUN-MLAYAH;DELMAS, 2001;BEREAU et al, 2003;ALBUQUERQUE et al, 2005;RYAN et al, 2006;CHUNHIENG et al, 2008).…”

Application of Chitosan and Buriti Oil (Mauritia Flexuosa L.) in Skin Wound Healing

“…The buriti is a smooth-stemmed palm tree measuring 23-50cm in diameter and 2.8-35m high, its leaf can be up to 5.83m long and with 120 to 236 segments, the fruit is orange-coloured covered with scales Corneas reddish brown [56]. The studies show that the word buriti came from the tupi-guarani (Indian language), dembyriti palm tree that emits liquid and after modifications and regional changes of this word came the term buriti, which is very common in almost all the Brazilian territory, giving names to streets, Cities, farms, among others.…”

“…Buritizeiro has a great cultural and economic value for the peoples of the regions where it is developed, since it provides a huge variety of products and uses, supporting or supplementing the income of several families, especially the Brazilian cerrado. It occurs in places where the soil is soaked, even in the dry season, thus being a source of clean water for people and animals [56,57]. Buriti (Mauritia flexuosa) is a plant typically found in the Amazon rainforest and is considered one of the most abundant palm trees in the country.…”

“…Together, antioxidant compounds, such as betacarotenoids and vitamin E, exert a protective effect on the new cells to form in the regenerating lesion. It is observed that high concentrations of unsaturated fatty acids have an important role in tissue regeneration, being an essential element for the formation and deposition of collagen fibres on the scar, besides promoting cell stimulation and proliferation [56,59,60,63]. The in vitro antibacterial and healing activity of buriti oil was performed by Batista et al [58], with greater sensitivity to buriti oil in B. subtilis, K. pneumoniae and S. aureus and the healing activity assay in the Fourteenth day in the oil-treated group, a significant reduction in macrophage counts was observed and a significant increase in fibroblast and collagen fibre.…”
