Elemental analysis of Ginkgo biloba leaf samples collected during one vegetation period.
The object of our work was the identification and quantification of inorganic elements in Ginkgo biloba L. leaves (Ginkgonis folium, Ginkgoaceae) by X-ray fluorescence analysis. The plant material was obtained from a 50-years-old female tree at the Comenius University Botanical Garden (Bratislava, Slovakia). Leaves were collected from early May to late September, with the last sample consisting of fallen leaves. The elements analyzed were: phosphorus, sulfur, potassium, calcium, scandium, iron, zinc, yttrium, molybdenum, tellurium, samarium, gadolinium, dysprosium, iridium, thallium and lead. The amounts of the monitored heavy metals were below the limits specified in Ph. Eur. 7 and PhS 1.
