Investigation of macro-micronutrients, flavonoids, and vitamins contents of Taraxacum officinale L

A leaf of Taraxacum officinale L. contains biologically active components are sesquiterpenic lactones, biotin, inositol and vitamins such as A, C, B, D, E and K. Leaves of T. officinale are rich in fiber, protein, and nutrients such potassium, iron, Fe and Ca phosphorus, calcium, and magnesium.The leaves can be eaten cooked or raw in various forms, for assembling salads or soup, which also recommended as a natural source of vitamin C in the early spring.It has been widely used for hepatitis, rheumatism, anti-inflammatory, antioxidative, anticarcinogenic, analgesic, antihyperglycemic, anticoagulatory, antioxidant, treat anemia, choleretic, diuretic, hepatoprotective and anti-inflammatory properties.The experimental results showed significantly higher content of total chlorophylls (3.79 mg/g), and carotenoids (3.85 mg/g) in leaves of T. officinale in the territory of the Chatkal State Biosphere Reserve.It was also found to contain four flavonoids such as rutin, gallic acid, hyperazide, and apigenin ranged from 83.432 to 16.041 mg/100 g; and four vitamins such B2, C, B12, and B9 ranged from 34.962 to 18.248 mg/100 g.Among the macroelements, there were significantly higher levels of potassium (K), calcium (Ca) and phosphorus (P), and significantly lower levels of magnesium (Mg), and sulphur (S).In the case of microelements, significantly greater iron (Fe), aluminium (Al), silicon (Si), barium (Ba), manganese (Mn) and zinc (Zn).microelements such as Fe, Al, Si, Ba, Mn, Zn, boron (B), copper (Cu), molybdenum (Mo), and chromium (Cr), ranged from 6.361 to 0.052 mg/g.
