“…The results exhibited that tucuma oil could induce cell proliferation on PCL fiber mats. In agreement with the results obtained on this paper, Ongaratto et al [50] studied the cellular viability of different tucuma extract concentrations (5,10,50, 100 e 500 μg/mL) on PBMCs. The viability of the cells seeded on the pure PCL fibers mats was significantly lower than that of cells cultured on the control well, this result can be credited to the PCL fibers hydrophobic nature [51] .…”

The aim of this study was to incorporate tucuma oil (Astrocaryum vulgare) into PolyCaprolactone (PCL) electrospun fibers and evaluate its physicochemical properties and cell viability. FTIR and DRX confirmed that tucuma oil (TO) does not affect the chemical properties of PCL and that the oil was loaded into the PCL microstructure, while TGA analysis showed that the oil increased the thermal stability of the polymeric fibers. SEM showed that the addition of the oil modified fibers structure by reducing the average fiber size from 5.5 μm to 1.7 μm for TO loaded samples. Cell viability assay demonstrated an increment on cell proliferation from 80% of pure PCL to 100% for samples containing TO. Therefore, it can be concluded that tucuma oil can be incorporated into PCL to form fibers by electrospinning, without meaningful changes in its physicochemical properties and increasing its biocompatibility.

“…Carotenoids are known as lipophilic substances with bioactive properties in the prevention of several types of cancer (Rowles and Erdman, 2020). Other studies investigated the constituents and health effects of oil and extracts of tucumã, demonstrating its antimicrobial and anti‐inflammatory properties (Baldissera et al ., 2018; Cabral et al ., 2020; Ongaratto et al ., 2020; Rossato et al ., 2020). These findings highlight the potential benefic effects on human health and nutrition by the intake of tucumã fruit and its oil.…”

This study aimed to investigate the effects of two, conventional and green, extraction techniques on the nutritional, bioactive and physicochemical properties of oils from Astrocaryum vulgare pulp. It is an Amazonian oilseed named tucumã, known by their oily nature and bioactive properties. n-Hexane (N-HE) and supercritical CO 2 (SFE-CO 2 ) were used as extraction solvents. Higher oil yield, 39.63%, was achieved using N-HE then SFE-CO 2 , 36.75%. The SFE-CO 2 oil presented low acidity and peroxide content, 0.9 mg KOHg −1 and 1.1 mEq kg −1 , while the N-HE presented 3.25 mg KOH g −1 and 2.4 mEq kg −1 , respectively (P < 0.05). The SFE-CO 2 oil exhibited greater content of linoleic (~42.3%) and oleic acids (~32.6%) (P < 0.05) and higher β-carotenes, up to 1100 μg 100 g −1 , while the N-HE oil had ~877 μg 100 g −1 . SFE-CO 2 had positive effect on the physicochemical and nutritional properties of A. vulgare pulp oil, which was statistically confirmed by principal component analysis (PCA). Practical applications The application of green techniques based on supercritical CO 2 fluid extraction to obtain biolipids from A. vulgare pulp with greater nutritional quality contributes to its potential utilisation as a functional ingredient in foods.
