“…Bioactive compounds have been shown to possess antioxidant properties that can buffer the adverse effects of free radicals. As coloured plants contain a significant amount of bioactive compounds, it is believed that frequent consumption of these plants may reduce the risk of NCDs such as cardiovascular disease, hypertension, diabetes and cancers (Dwiyanti et al, 2018;Jafarian et al, 2014;Tan et al, 2010a).…”

PurposeLiterature has consistently reported that coloured plants are rich in dietary bioactive compounds. Therefore, this study aims to compare the total phenolic content and antioxidant activities in selected coloured plants (blue butterfly pea flower, roselle calyx, yellow bell pepper and purple sweet potato).Design/methodology/approachTotal Phenolic Content (TPC) was determined using Folin–Ciocalteu assay, while antioxidant activities were evaluated using 2,2-dophenyl-1-picryl-hydrazyl-hydrate (DPPH) radical scavenging, Ferric Reducing Antioxidant Power (FRAP) and Trolox Equivalent Antioxidant Capacity (TEAC) assays.FindingsTPC was reported from 273.15 ± 19.57 µg GAE/g DW (blue butterfly pea flower extract) to 363.10 ± 7.94 µg GAE/g DW (roselle calyx extract). Antioxidant activities as determined by DPPH assay ranged from 17.26 ± 0.06% (purple sweet potato extract) to 83.38 ± 1.04% (yellow bell pepper extract); while for FRAP assay was 4.92 ± 0.18 mg Fe (II)/g DW (purple sweet potato extract) to 128.33 ± 11.59 mg Fe (II)/g DW (roselle calyx extract). On the other hand, TEAC values were in the range of 15.26 ± 2.83 µg Trolox/g DW (roselle calyx extract) to 364.27 ± 7.14 µg Trolox/g DW (blue butterfly pea flower extract). A significant moderate positive correlation was observed between TPC and DPPH (r = 0.562) as well as TPC and FRAP (r = 0.686).Originality/valueThis study was the first to compare the total phenolic content and antioxidant activities in coloured plants. Findings derived from this study can be extended to the formulation of natural food colourants and nutraceuticals.

“…During the fermentation process, partial divisions or changes in glucoside occur, along with an increase in glucoside and glucuronidase activities, which release strong antioxidant compounds formed through flavonoid transformations [ 30 , 31 ]. PSP also has a high antioxidant content and contains anthocyanin color pigments that are useful antioxidants, with higher stability compared to other anthocyanin sources [ 32 , 33 ]. Antioxidant contents in BST and PSP become the main factor in the improvement of testicular dysfunction and sperm parameters, as well as the AGE and RAGE formation in the testis of DM model rats.…”

Background and Aim: Hyperglycemia increases advanced glycation end-product (AGE) production, and the activity of receptor for AGE (RAGE) in testis, which leads to testicular histopathological damage and infertility. This research investigated the effect of black soybean tempeh (BST), purple sweet potato (PSP), and its combination on AGE and RAGE expression and spermatozoa quality in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: The rats were given high-fat diets for 5 weeks, then were injected intraperitoneally with multiple low doses of STZ (30 mg/kg body weight). Diabetes mellitus (DM) rats were divided into seven groups: DM, DM+glibenclamide, DM+BST, DM+PSP, and DM+combination of BST and PSP in ratio 1:3, 2:2, and 3:1 as C1, C2, and C3, respectively. The rats were treated for 30 days. Testicular AGE and RAGE expression and spermatozoa quality were measured. Results: The combination of BST and PSP significantly decreased AGE and RAGE expression in testicular organs and improved spermatozoa quality compared to the normal group. Conclusion: The combination of BST and PSP can be used as future alternatives to improve spermatozoa quality in DM patients.

“…Pada ubi jalar merah yang ditemukan dominant adalah jenis pelargonidin-3-rutinoside-5-glucoside, sedangkan pada ubi jalar ungu adalah antosianin dan peonidin glikosida yang mempunyai aktivitas antioksidan lebih kuat [2]. Dengan demikian ubi jalar ungu mempunyai potensi besar sebagai sumber antioksidan alami dan sekaligus sebagai pewarna ungu alami [3]. Ubi jalar ungu juga mengandung senyawa antioksidan alami mampu memperlambat, menunda, ataupun mencegah proses oksidasi.…”
