Antioxidants from the Leaf Extract of Byrsonima Bucidaefolia

Abstract: The radical scavenging assay-guided fractionation of the leaf extract of Byrsonima bucidaefolia Standl. yielded two metabolites with antioxidant activity, identified as methyl gallate (1) and methyl m-trigallate (2) on the basis of their spectroscopic data. Both 1 and 2 were identified as artifacts of the extraction and/or the purification process, possibly resulting from transesterification of precursor gallotannins. Evaluation of the antioxidant activity of both the isolated metabolites 1 and 2 and three of … Show more

“…As expected, the extract of the fruits of B. bucidifolia showed the highest antioxidant activity in the DPPH radical reduction assay, confirming the direct correlation between antioxidant activity and the TPC. While there are no reports on the phytochemistry of the fruits of B. bucidifolia, a study carried out on the antioxidant activity of the leaf extract of the plant resulted in the isolation of two bioactive metabolites identified as artifacts originating from gallotanin-type precursors [14]. Alternatively, testing of the antioxidant activity of the different extracts using the FRAP assay showed the highest activity in the extracts from the fruits of M. bijugatus, P. acidus, and S. purpurea.…”

“…The total antioxidant capacity assay measuring the DPPH radical reduction capacity of all extracts was carried out following the methodology reported by Castillo-Avila et al [14]. A 25 μM ethanolic solution of DPPH was prepared minutes before being used to prevent decomposition.…”

“…Notably, B. bucidifolia contains active metabolites like methyl gallate (C 8 H 8 O 5 ), which significantly contributes to the DPPH free radical scavenging. Both compounds exhibited more potent antioxidant activity than vitamin C (6.5 µg/mL), with an EC 50 of 0.9 µg/mL [27].…”

“…Byrsonima bucidaefolia Standl, known as "sakpah" and "sak bo'ob" in the Yucatan Peninsula, is a native plant belonging to the Malpighiaceae family. In traditional medicine, this species is used to treat asthma, fever, and skin infections [27]. Byrsonima species have been found to produce bioactive compounds such as saponins, flavonoids, tannins, and triterpenes, which exhibit various biological properties, including fungicidal, antibacterial, and cytotoxic activities [80].…”

“…However, both metabolites were confirmed as artifacts of the extraction/purification process, possibly resulting from transesterification of precursor gallotannins. 70 More recently, a mixture of thymol ( 23) and 3-methyl-4isopropylphenol (97), together with the new 3,4-O-dicaffeoylquinic acid methyl ester (98) and the previously reported dicaffeoylquinic acid derivatives, 3,5-O-dicaffeoyl-epi-quinic acid methyl ester (99) and 3,5-O-dicaffeoylquinic acid (100), were identified as the bioactive products responsible for analgesic and anti-inflammatory effects shown by the root extract of Calea urticifolia (Mill.) DC.…”
