... method and in powders (clarified with NaOH 5% solution) analysed at the optical microscope for the identification of the specific anatomical elements; the chemical quality exam of the ethereal, alcoholic and hydrous extracts, to identify the active principles through specific reactions encountered in the specialized literature (Ciulei et al., 1995). The quality of the vegetal product was appreciated by the determination of the weight lost while drying and by measuring the poliuronide in the cold soaking process (Ciulei et al., 1995). The macroscopic exam confirmed the species description in the specialized literature. The microscopic exam realized in the transversal section of the vegetal produce showed the following anatomical characteristics: - epidermis formed by cells with thickened internal and external walls - thin rind formed by 3-4 layers of small cells which have between them a lot of aëriferous lacunas - the conducting tissues are made up of 19 to 20 libero – ligneous fascicles which are separated between them by very large and sclerificated rays - the liber is formed by cribrate tubes and annexed cells separated by parnchymatous elements - the cambium formed by 2-3 layers of cells - the wood is formed by rounded ducts stuck into ligneous parenchyma - central there is the cellulosic and parenchymatous medulla of meatic type (Fig 5 and 6). - the superior epidermis formed by heteromorphic cells which have the external wall thickened; some cells are transformed into unicellular branched protective hairs. - the mesophyll is formed by palisadic and lacunose tissue the lower epidermis has branched protective hairs. - the median nervure has only one libero- ligneous fascicle (Fig. ...
