measurementThe phytate content in Solanum nigrum (536 µg/100 g edible portion) is slightly lower than values obtained in a study conducted in Nigeria by Akubugwo et al. (2007).

measurementPhytate content in tubers of Dioscorea alata, Dioscorea cayenensis, and Dioscorea prehensilis ranged between 31.06 and 96.48 µg per 100 g fresh edible portion.

referenceVaintraub and Lapteva (1988) described a colorimetric method for determining phytate in unpurified extracts of seeds and their processing products.

claimCooking green vegetables and tubers reduces the levels of phytates, tannins, and oxalates.

claimHigh phytate content inhibits the bioavailability of minerals, according to FAO and WHO (2001).

claimCalcium and phytates determine the bioavailability and absorption of iron.

claimThe phytate values for tubers in the study are lower than those reported in Nepal for similar species by Wanasundera and Ravindran (1994).

measurementPhytate content in the analyzed plant species varied from 31.06 to 601.65 µg/100 g, with the lowest levels found in Dioscorea prehensilis (31.06 µg/100 g) and D. alata (90.17 µg/100 g), and the highest levels found in Carissa spinarum (601.65 µg/100 g) and Solanum nigrum (536.48 µg/100 g).

measurementPhytic acid content in the studied species varied from 31.06 μg/100 g fresh edible portion in Dioscorea prehensilis to 601.65 μg/100 g fresh edible portion in Carissa spinarum.

Vernonia amygdalina: a comprehensive review of the ... frontiersin.org Frontiers 7 facts

measurementVernonia amygdalina contains 305 mg/g of flavonoids, 104 mg/g of phytate, 6 mg/g of saponin, 1.7 mg/mL of tannin, and 20 mg/mL of alkaloids.

claimPhytochemical screening of Vernonia amygdalina revealed the presence of phytate, oxalate, cyanogenic glycosides, anthraquinone, and phenol.

measurementVernonia amygdalina (bitter leaf) contains 139 mg/g of alkaloids, 180 mg/g of flavonoids, 60 mg/g of saponin, 2.3 mg/g of oxalate, and 167 mg/g of phytate.

claimChemical analysis of Vernonia amygdalina reveals the presence of flavonoids, alkaloids, saponins, tannins, triterpenoids, sesquiterpene lactones, steroids, cardiac glycosides, oxalates, phytates, cyanogenic glycosides, and phenols.

claimAbrading Vernonia amygdalina leaves significantly decreases nutrient and antinutrient (phytate and tannin) levels, causes a large decrease in proximate and mineral composition, increases magnesium content, and results in no significant change to carbohydrate content.

procedureBlanching and abrasion are methods used to reduce anti-nutritional components such as tannin and phytate in Vernonia amygdalina leaves, according to Yakubu et al. (2012).

claimOvernight soaking, blanching, and abrasion significantly reduce the mineral, tannin, and phytate contents of Vernonia amygdalina.

procedureYu et al. developed a sound-absorbing foam using bamboo pulp, halloysite nanotubes (an alumina-silicate-based mineral), chitosan, and phytic acid, utilizing a layer-by-layer arrangement to improve porosity and mechanical properties.

claimYu et al. modified wood samples using carboxymethylated alkali lignin, phytic acid, and melamine-urea-glyoxal resin to enhance fire resistance properties.

measurementWood modified by Yu et al. with lignin, phytic acid, and melamine-urea-glyoxal resin demonstrated a 56.8% reduction in heat release, a 92.3% decrease in smoke generation, and an improvement in Limiting Oxygen Index (LOI) from 23.6% in natural wood to 41.5% in the modified sample.

referenceJiang et al. developed a one-pot complexation method using phytic acid and polyethyleneimine on cellulosic microfibers to create insulative and flame-resistant foam.

claimThe fire-extinguishing mechanism of wood modified by Yu et al. with lignin, phytic acid, and melamine-urea-glyoxal resin involves a synergistic gas and solid phase process: the lignin generates a dense char layer acting as a physical barrier, while the gas phase involves the release of CO2 and nitrogen/phosphorus-containing gases that dilute oxygen and inhibit combustion chain reactions.
