Abstract: Introducere. Ţesutul secretar este alcătuit din celule vii, specializate în sinteza anumitor compuşi chimici care pot fi eliminaţi în exterior sau depozitaţi în interior. După compoziţia chimică aceşti compuşi sunt foarte diverşi: uleiuri volatile, balsamuri, răşini, gume, mucilagii, taninuri, latexuri, apă, oxalat de calciu. Ţesuturile secretoare se clasifică în: externe şi interne. Scopul lucrării a constat în stabilirea caracterelor microscopice specifice ţesutului secretar în unele produse vegetale. Material si metode. în calitate de obiecte de studiu au servit florile, frunzele, părţile aeriene şi fructele plantelor medicinale care dezvoltă ţesuturi secretoare. Au fost realizate micropreparate temporare clarificate şi secţiuni. Imaginile au fost obţinute la microscopul optic Mieros MC300 Austria, Camera V300. Rezultate. în urma analizei microspice au fost puse în evidenţă elementele ţesutului secretar extern şi intern: peri secretari, peri glandulari, glande, canale secretoare, cavităţi schizogene şi lizigene, laticifere. Concluzii. Formaţiunile ţesutului secretar pot servi în calitate criteriu de identificare a produselor vegetale. Imaginile obţinute pot fi utilizate în calitate de reper la analiza microscopică a produselor vegetale.
Introduction. Secretory tissue is made up o f living cells specialized in synthesis of specific chemical compounds that can be secreted outside or stocked inside. The chemical composition of these compounds is of huge variety, there can be found essential oils, balms, gums, mucilages, tannins, liquid rubbers, water, calcium oxalates. Secretive tissue can be classified in two categories: external and internal. The aim of the study was to establish specific microscopic traits of medicinal vegetable products characterized by the presence of secretory tissue. Material and methods. The selected objects of study were flowers, leaves, aerial parts, fruits of medicinal plants that develop secretory tissue. Temporary clarified minipreparations and sections were realized. The images were obtained throughout Micros MC300 Austria, Camera V300 optic microscope. Results. The microscopic analysis revealed the elements of external and internal secretory tissue: secretory trichomes, glandular trichomes, glands, secretory, lysigenous, and schizogenous cavity, laticifers. Conclusions. The structures of secretory tissue serve as an identification criterion of medicinal vegetable products. The obtained images may be used as a landmark in microscopic analyzis of these medicinal materials.
