Long-Term Variability in the Content of Some Metals and Metalloids in Flowers: A Four-Year Study Using ICP OES and PCA Analysis.

This study investigates the content of some metals and metalloids in the flowers of three cultivars (AHP, pure species, with white flowers; AHH, hybrid species, with pink flowers; and AXC, , with red flowers) over a four-year period (2016-2019) using inductively coupled plasma optical emission spectrometry (ICP OES) and principal component analysis (PCA). The research focuses on assessing macro- and micro-elemental compositions, identifying variations in mineral uptake, and exploring potential correlations with soil composition. Results highlight significant differences in elemental profiles among the three species, despite similar total ash content.

Mineral Composition Analysis of Red Horse-Chestnut () Seeds and Hydroalcoholic Crude Extract Using ICP OES.

This study presents findings on the metal and metalloid composition of red horse-chestnut ( × , ) seeds, determined by the ICP OES technique. Samples were collected from five AXC plants located in Modena (Italy) over four consecutive years (2016-2019). The seeds underwent proximate analysis, which included measurements of moisture content, proteins, lipids, carbohydrates, ash, and elemental composition.
