Lavandin (Lavandula hybrida Reverchon) is related to Lavandula angustifolia, but the species cultivated in Romania are poorly studied in terms of their secondary metabolites and their uses in therapy. The purpose of the study was mainly to reveal the microscopic characteristics of Romanian lavandin grown in Piatra Neamț, Romania. Moreover, the biological potential of volatile fractions isolated from lavender (used for comparison) and lavandin were assessed especially on standard microorganisms. The results indicated similar microscopic elements, and some common chemical characteristics to Lavandula angustifolia, but also an important variation regarding the antimicrobial activity of the essential oils.
