Study of chemical composition and antioxidant activity of magnolia plant seed

Abstract

In the article, some physiological and biochemical properties of the seeds, leaves, and inflorescences of Magnolia soulangeana, Magnolia grandiflora, and Magnolia stellate, introduced in Uzbekistan, were studied. In particular, the amount of macro- and micronutrients in the generative organs was determined and analyzed. The amount of heavy metals and toxic substances such as Cd, Sb, Ng, Va, As in Magnolia soulangeana and Magnolia Grandiflora plants was also determined. Antioxidant activity of plant species gultoji leaves was also studied. When comparing the indicators of studied species Magnolia soulangeana, Magnolia Grandiflora and Magnolia stellate, it was observed that antioxidant activity is relatively low in Magnolia Grandiflora species.
