ABSTRACT = {This work aims to determine the phytochemical characterization of the
pericarp of <i>Chamaedorea radicalis</i> Mart. fruit as a non-timber product with
potential to obtain phytochemicals with potential applications in the industry.
Fruit from <i>C. radicalis</i> were grouped in four ripening stages named as S1, S2,
S3 and S4, according to maturity; S1 the most unripe stage and S4 the completely
ripe stage. Determinations of total phenolic compounds, free radical scavenging
activities and total flavonoid contents using spectrophotometric methods were
done. Also, the tentative identification of phytochemicals during fruit ripening
was done using UPLC-MS-MS. Total phenolic compound (TPC) content ranged
from 7.24 to 12.53 mg gallic acid equivalents per gram of fresh weight (mg GAE/
g FW). Total flavonoids (TF) contents ranged from 0.163 to 0.23 mg of quercetin
equivalents per g FW (mg QE/g FW). Free radical scavenging activity against
DPPH and ABTS radicals varied from 40.80 to 53.68 and from 22.29 to
37.76 mmol Trolox equivalents g FW (mmol TE/g FW), respectively. Antioxidant assay in vitro by FRAP (ferric reducing antioxidant power) method showed
that S3 was the highest level with antioxidant power while S4 was the lowest
with Red ripeness stage showed the lowest contents for all determinations. Mass
spectrometry allowed detection of 26 compounds, including phenolics, alkaloids
and saponins. Afzelin, Kaempferol 3-neohesperidoside and the four saponins
identified were present in all ripeness stages. Preliminary phytochemical identi-
fication and the spectrophotometric determinations showed that the pericarp of
<i>C. radicalis</i> presented antioxidants and compounds related to alkaloids, phenolics and saponins. The presence and abundance of each phytochemical regarding
each ripeness stage should be considered.},
