“…While antioxidant compounds generally contain a phenolic group, it was typically analyzed with the Folin-Ciocalteu reagent and used gallic acid as a reference standard. This method uses the UV-vis technique to analyze the simple, convenient, economical, highly accurate, and transparent results of the experiment [21][22][23][24].…”

In Thailand, the roselle seeds have a few utilizations other than seeds for planting propagation. Consequently, this study aimed to evaluate the nutritional and mineral profile of roselle seeds in the Northeast region of Thailand. The obtained results proved that roselle seeds were found to be a good source of carbohydrates (41.48 ± 0.31 %), protein (30.40 ± 0.09 %), and fat (19.70 ± 0.04 %). Additionally, the results indicated that roselle seeds were a rich source of fiber (40.61 ± 0.26 %) and had a high energy content (1945.03 ± 12.31 KJ/100 g of sample). The macronutrients and micronutrients of the roselle seeds, such as K, P, Mg, Zn, Fe, Mn, and Cu, were found to be 2092.50 ± 1.89, 891.22 ± 3.71, 366.00 ± 1.34, 7.17 ± 0.13, 6.81 ± 0.20, 5.88 ± 0.14 and 4.22 ± 0.11 mg/g of sample, respectively. Furthermore, the total phenolic compounds as bioactive components and DPPH radical scavenging capacity were equal to 21.22 ± 0.24 mg GAE/100 g of sample and 46.28 ± 1.35 %, respectively. Thus, the roselle seeds were considered a cheap nutrient source and could be a good source of potential food ingredients. HIGHLIGHTS The roselle (Hibiscus sabdariffa) seeds derived from Roi Et Province in the Northeast region of Thailand have a highly rich source of nutrients, bioactive compounds, and minerals The roselle seeds were considered a cheap nutrient source and could be a good source of potential food ingredients GRAPHICAL ABSTRACT

“…When cooked Krabok seeds have an energy value of 763.39 Kcal while uncooked Krabok seeds have an energy value of 742.17 Kcal. It is noteworthy that Krabok seeds possess approximately 2.4 times the energy content compared to RD 6 sticky rice [12]. The energy values of food samples can vary due to factors such as variations in seed quality, processing methods, and analytical techniques utilized in different studies.…”

This investigation examined the nutritional value, mineral content, total phenolic content, antioxidant activity and cytotoxicity of uncooked and cooked Krabok seeds. Proximate analysis was carried out to determine the nutrient composition of uncooked and cooked Krabok seeds. The average fat, protein, carbohydrate, moisture, ash, and fiber contents were found to be 75.42, 11.78, 6.72, 2.68, 1.85 and 1.54 %, respectively. The Folin-Ciocalteu method was employed for the quantitative analysis of total phenolic compounds. All 6 samples of Krabok seeds extracted, both cooked and uncooked, were extracted using hexane, ethyl acetate, and ethanol, and subjected to the test. All the extracted samples contained phenolic compounds, with amounts ranging from 29.10 to 130.26 µg GAE/mL. The highest levels of phenolic compounds were observed in the ethanolic extract of cooked Krabok seeds. The antioxidant properties were evaluated using the DPPH assay. The scavenging activity of the extracted Krabok seed samples ranged from 9.84 to 62.31 %. The ethanolic extract of uncooked Krabok seeds exhibited the highest antioxidant activity. To assess the toxicity of the Krabok seed extract, HaCaT, Vero and RAW 264.7 cell liness were employed using the MTT technique. The results revealed that cell survival remained above 80 % for all doses of both uncooked and cooked Krabok seed extracts. These findings suggest that Krabok seeds are a valuable source of fat and other essential nutrients. The crude ethanolic extract exhibited a significant amount of phenolic content and antioxidant activity. Therefore, it could be utilized in the production of snacks or cosmetics. HIGHLIGHTS Krabok seeds has high nutrients and energy value. Krabok seeds has high phenolic compounds and non-toxic to cells. Krabok seeds were thought to be an inexpensive source of nutrients and a reliable supply of prospective culinary ingredients. GRAPHICAL ABSTRACT
