Pharmacognostic Survey on Paeonia Broteri – An Iberian Endemism

The genus Paeonia (Paeoniaceae) includes perennial plants distributed throughout the northern hemisphere and some of these are used in traditional medicine cultivated as ornamental species. broteri is endemic to Iberian Peninsula current paper first report on a pharmacognostic survey its roots, leaves corresponding powders. Using light scanning electron microscopy, simple compound polyhedral starch grains, with fissure-type hilum no striae, recorded root phelloderm cells presence idioblasts druse-type calcium oxalate crystals, addition isolated stone cells, also common. Irregular sinuous epidermal can be detected both leaf surfaces anomocytic stomata, an elliptical-rounded shape, only abaxial face. In leaves, crystals appear along vascular tissues. histochemical tests allowed situ localization chemical groups most relevant were polyphenols terpenoids.
