Pharmacognostic research of promising herb raw materials Pulmonariae herba and Pulmonariae folia

Introduction. Generative shoots and rosette leaves of genus Pulmonaria plants are used for making phytoremedies with various pharmacological activity.

Objective: The aim was pharmacognostic research of herb raw material from two producing plants – P. mollis and P. obscura.

Material and methods. The studying objects were generative shoots and rosette leaves collected during the growing season. The trace elements amount (Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se) was determined by mass spectroscopy and phenolic constituents – high-performance liquid chromatograph methods.

Results. Analysis of built hierarchical tree revealed that the rosette leaves of both sourges form a cluster that differs from cluster formed by generative shoots. The phenol complexrosette leaves revealed is characterized by flavones.

The polysaccharides content is important because they form expectorant action of medicines made from Pulmonariae folia. On other side they are serving as a matrix for ferro-ions, which are necessary for forming antianemic effect of remedies made from Pulmonariae herba.

Conclusion. It was established, trace element status and composition of biologically active compounds of lungwort generative shoots and rosette leaves are different. Rosette leaves collected after fruiting phase– (Pumonariae folia) and generative shoots collected in flowering phase (Pulmonariae herba) should be considered as two different kinds of herb raw material. Both of lungwort species are acceptable sources of appropriating both of herb raw material. The polysaccharides content is offered as an indicator determing the quality of raw materials. In addition, the content of hematopoietic complex microelements should use as the quality indicators.
