In addition to the well-known carotenoids, the current study investigates the antioxidant activity of the four major species and the involvement of other antioxidant chemicals such as phenolics. In vitro antioxidant capabilities of four Trentepohlia species (T. abietina, T. arborum, T. diffracta, and T. umbrina) were assessed, and all four species were found to be high in phenolic compounds, which was a surprise discovery. On the other hand, T. abietina extract had the largest total phenolic component and flavonoid content, as well as the strongest scavenging action and the lowest IC50. In the order T. abietina >T. arborum>T. diffracta>T. umbrina, the scavenging activity of the four Trentepohlia species extracts decreased. Furthermore, the DPPH radical scavenging activity and superoxide anion radical scavenging activity of the four species differed significantly. When it came to reducing power, extracts from all four species were concentration dependent, with high reducing power at higher concentrations and gradually decreasing as the concentration of the extracts fell. When comparing the species, T. abietina once again shown the strongest reducing power at all concentrations. The study revealed a favourable link between increased flavonoids content and increased scavenging activity. The presence of predominantly flavonoids constituents could be linked to the scavenging effect displayed by the extract of four species of Trentepohlia, primarily the DPPH scavenging activity. This clearly suggested that the DPPH scavenging action exhibited by the extract of all four Trentepohlia species may be linked to the presence of primarily flavonoids constituents in this case.
