ABSTRACT:

Big chili has the largest fruit size compared to other types of chili. In addition to having a spicy taste, big chilies contain other beneficial biochemicals such as phenolics, flavonoids, antioxidants, and α-glucosidase inhibitors that have the potential to be developed for functional tropical plants. Information on the content is still not widely found. Therefore, this study identified biochemical compounds (TPC, TFC, DPPH, FRAP, AGI) in several genotypes of big chili peppers. From October to November 2021, we conducted a study using the microplate reader method. We repeated the experiment three times. The research design used was a completely randomized design with a single factor genotype. A total of 22 genotypes of big chili were used in this study. The big chili genotype F6074136-2-3-2-3 had the highest content of α-glucosidase inhibitor and antioxidant FRAP compared to other genotypes 67.62% and 71.20 mol TE/g extract. The genotypes CK 12 and F6074077-1-1-3-1 indicated the highest phenolic and flavonoid contents. The correlation between biochemical parameters showed that TPC-AGI and TPC-DPPH were significantly negatively correlated. The conclusion is that the information in this study can be the basis for the development of functional tropical plants in future research.
