The TPC, TFC and antioxidant potential of the extracts were also determined. The stability of the extracts during storage at different temperatures (4 °C, − 20 °C and − 80 °C) was investigated at weeks 0, 4 and 8. The results showed that the bark of <em>F. racemosa</em> and leaves of <em>F. benjamina</em> contained the highest amounts of phenolic content, with significantly higher antioxidant properties. PLSR analysis revealed that the secondary metabolite composition strongly influenced the antioxidant activities differently with <em>Ficus</em> trees. VIP scores were also computed to determine the most important factors that contributed to the ABTS and FRAP activities in the extracts from each species. Specifically, TPC, TFC, TXc, TCC, chlorophyll a, and chlorophyll b contents were the most important variables for <em>F. benjamina</em>. Meanwhile, TPC, TAC, TFC and chlorophyll b were the most important factors for <em>F. racemosa</em>, and only TAC, TPC and chlorophyll b were the most important factors for <em>F. religiosa</em>. Long term storage (8 weeks) of the extracts at 4 °C was observed to cause the highest percentage of metabolite degradation (up to 88.56% in TXc, 66.86% in TPC and 81.93% in TFC). Storage at − 80 °C was found to be the most suitable for retaining the secondary metabolites content and bioactivities of the samples.

The findings of this study highlight the huge potential of plant extracts as both natural pigments and antioxidants in the food industry.
