Vernonia amygdalina is related to phytic acid because the plant contains phytate as a phytochemical component, as confirmed by screening and chemical analysis in [1] and [2]. Quantitative measurements of phytate levels in the plant are provided in [3] and [4], while [5], [6], and [7] describe processing methods used to reduce its phytate content.

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.
