ABSTRACT

The phytochemical compounds in the leaf extracts of Castanopsis indica and C. tribuloides were evaluated, and their antioxidant and antimicrobial potential were assessed. The TPC was found to be 193.12 and 159.49 mg GAE g−1 dry weight, and the TFC was 108.12 and 96.49 mg QE g−1 dry weight, for C. indica and C. tribuloides, respectively. C. indica had higher DPPH scavenging activity, with an IC50 value of 15.10 μg mL−1. Both extracts showed substantial antimicrobial activity against the tested bacteria. GC-MS analysis showed the presence of 76 VoCs in C. indica leaf, and 71 VoCs in C. tribuloides.
