Total phenolics, flavonoids, antioxidant activity, and α-glucosidase inhibitory activity of ornamental pepper and several other lines

Abstract

Ornamental chili is a type of chili plant that favors the value of beauty but still has a spicy taste. It generally has a purple fruit color because they contain anthocyanins. The biochemical content in ornamental chili is believed to have benefits for human health. This study aims to identify several biochemical compounds in several genotypes of ornamental chili and pure lines. The study was conducted using the microplate method which was repeated three times. The research design used was a completely randomized design with a single factor genotype. Sixteen genotypes of chili were used, consisting of 4 genotypes of ornamental chilies and 12 genotypes of pure lines. The results showed that the ornamental chili genotype Nazla IPB contained 83.27% α-glucosidase inhibitory activities. The pure lines genotype F10 145174-9-7-1-5-3-1-2-5 contained the second-largest α-glucosidase inhibitory activities (80.67%) and the highest antioxidant DPPH (15.40 μmol TE g.-1 extract). The highest antioxidant of the FRAP method was shown in Adelina IPB’s ornamental chili. The correlation between biochemical parameters showed that DPPH-AGI was significantly positively correlated and FRAP-AGI was negatively correlated. It is concluded that the information in this study can be the basis for the development of functional ornamental plants in future ornamental chili breeding research.

Biochemical and Yield Component of Hybrid Chili (Capsicum annuum L.) Resulting from Full Diallel Crosses

“…α-glucosidase inhibition has an important role in helping patients with type 2 diabetes mellitus [17]. Interestingly, ornamental chilies in our previous study had relatively high levels of AGI compounds [9].…”

“…All sample preparations use 70% ethanol on chilies previously made into powder [9,15]. Harvested ripe fresh chilies were baked in the oven for 48 h at 40 • C. After drying, they were crushed into powder using a blender of up to 10 mesh sizes.…”

“…Chili is reported to be one of the contributing factors to inflation in various countries, especially Indonesia [6]. The majority of the Indonesian population uses chilies for fresh consumption and raw materials for processed spicy foods called sambals [7], made into dry powder [8], and several chili varieties are reported to be used as ornamental plants [9,10]. Variations in the utilization of chilies depend on the type and variety of chilies used.…”

Total phenolic, flavonoid contents, and antioxidant activity of three selected Portulaca grandiflora mutants in MV8 generation as a result of recurrent irradiation technique

“…The whole plant part of the P. grandiflora was extracted as the test sample solution. The sample extraction was using the maceration method with slight modifications [23]. Beginning with weighing the fresh weight, then the three selected genotypes of P. grandiflora were dried using an oven until the water content reached less than 10%.…”

Selection of ideal genotypes in peppers with ornamental potential

“…Therefore, the biochemical compounds in their fruits are also important. Sahid et al (2022) conducted a study to identify these compounds in ornamental pepper genotypes and found high contents of alpha-glucosidase inhibitors (AGI), reaching up to 83.27%. They attributed the high inhibitory activity of alpha-glucosidase to the purple colour of the fruits, indicating their potential in the prevention and treatment of diabetes.…”
