The bioactivity of some species of rattan fruit has been previously studied and it was found that it has potential antioxidant agents. This study was conducted to determine the antioxidant content in three species of edible rattan fruit, namely Calamus manan Miq., Calamus ornatus Bl. and Calamus caesius Bl by using the DPPH method, whereby the test was carried out on the pericarp, flesh, and seeds of each fruit. The research findings revealed that phytochemical compounds, i.e. flavonoids, tannins, and triterpenoids are found almost in all parts of the fruit, while steroid is not found in any of the three species of the fruit. The antioxidant activity found in the fruit of C. caesius Bl is strong, meanwhile the antioxidant activity in the fruit of C. manan Miq only strong in its pericarp and seeds, but it is moderate in its flesh. The antioxidant activity found in the fruit of C. ornatus Bl. is strong in its pericarp and seeds, but it is moderate in its flesh. Therefore, these three species of rattan fruit are potential as antioxidant agents.

“…34 The roots of M. armata and M. flexuosa had intermediate values of antioxidant activity when compared to the other analyzed structures, with EC 50 of 75.6 and 98.7 μg/mL respectively and although they presented antioxidant activity, the values are lower than that described for roots of Borassus flabellifer (15.75 μg/mL) that also belongs to the Arecaceae family. 35 The roots of the two species presented contents of flavonoids higher than those found in petioles, as can be observed in Table 4.…”

Mauritia flexuosa and Mauritiella armata belong to the family Arecaceae and are widely found in Brazil. Aim: In this work were evaluated: the phytochemical profile of the secretion popularly known as M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species, as well as the quantification of flavonoids and the chromatographic profile by means of High Performance Liquid Chromatography. Materials and Methods: The chromatographic profile was determined by high performance liquid chromatography, quantification of flavonoids and antioxidant activity, were performed by spectrophotometric method. Results: Antioxidant activity and presence of flavonoids were observed in the extracts of all the analyzed structures of the two species. The phytochemical profile of the wine evidenced the presence of secondary metabolites reported in other structures of M. flexuosa. In the chromatographic analysis, it was observed that the extracts evaluated have between three and nine compounds. Conclusion: Further studies should be performed to identify the active compounds in the two species. Key Messages: In this work were evaluated: the phytochemical profile of the secretion popularly known as M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species Mauritia flexuosa and Mauritiella armata (Arecaceae), as well as the quantification of flavonoids and the chromatographic profile. GRAPHICAL ABSTRACT SUMMARY• The current work were evaluated: the phytochemical profile of the M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species, as well as the quantification of flavonoids and the chromatographic profile by means of high performance liquid chromatography. • Researchers have been stated the presence of flavonoids and antioxidant activity of were observed in the extracts of all the analyzed structures of the two species. • Researchers have been stated the presence of phytoconstituents in wine. • In the chromatographic analysis, it was observed that the extracts evaluated have between three and nine compounds.

“…Clarke evaluated the ethanol and EAEs using the FRAP assay, indicating significant antioxidant activity [29] . Uddin evaluated the hydro-methanol extract of the aerial parts of I. quamoclit and reported substantial antioxidant activity using the DPPH scavenging assay [30] . Overall, these studies provide further evidence of the antioxidant potential of I. quamoclit and the presence of various phytochemicals that contribute to its antioxidant activity.…”

The emergence of new chronic and infectious diseases has spurred intense research efforts to identify new and effective substances for combating these global health challenges. Plants have been widely acknowledged as a principal source of drug discovery due to their remarkable ability to produce a diverse array of bioactive molecules. Thus, this study aimed to investigate the phytochemical and antioxidant potential of the crude extracts obtained from different parts of Ipomoea quamoclit. Various parts of I. quamoclit were collected, ground, dried, and processed into a coarse powder. Subsequently, solvent extraction using methanol and ethyl acetate was performed to obtain the extracts. The methanolic extract (ME) of the plant's leaves exhibited a higher phenolic content (6.097±0.189 mg/g of GAE) compared to the ME of the root (4.515±0.1884 mg/g of GAE). Additionally, the ethyl acetate extract (EAE) of the leaves showed a higher flavonoid content (12.815±0.234 mg/g of CAE) compared to the EAE of the root (11.229±3.558 mg/g of CAE). Moreover, the ME of the stem displayed a higher antioxidant capacity (41.488±0.684 mg/g of AAE) than the ME of the leaves (37.133±5.604 mg/g of AAE). The DPPH radical scavenging activity of the ME of the stem of I. quamoclit was 64.050%, comparable to that of BHT (77.48%). These findings indicate that I. quamoclit holds promise as a valuable source of phytochemicals and antioxidant compounds.
