In order to identify the medicinal and aromatic plants most requested for the treatment of the most common oral pathology, an ethnobotanical survey was carried out in the economic capital Casablanca, Morocco. The data basis was obtained draw selected traditional herbalists based on the semi-structured questionnaire. Quantitative indices such as use value (UV), family UV (FUV), fidelity level and informant consensus factor (ICF) were intended to evaluate the importance of plant species. A total of 46 plants species belonging to 22 families that were used. Juglandaceae family showed the highest significance (FUV = 0.75). We identified 40 species used for gum disease (gingivitis, periodontal abscess), 15 for dental pain (toothache, tooth sensitivity), 14 for halitosis, 12 for oral ulcers (aphtous, mouth ulcers and herpes), 3 for dental stain (teeth cleaning, sparkling and bleaching) and only 2 for tooth decay. The used plants are mainly prepared as decoction (80.4%). Syzygium aromaticum (UV = 0.94) was the specie most commonly prescribed by local herbalists. The higher ICF (0.75) was registered for the use gum disease.Graphical Abstract Electronic supplementary materialThe online version of this article (10.1007/s13659-018-0194-6) contains supplementary material, which is available to authorized users.

The quality and the variability of the chemical composition and antimicrobial properties of essentials oils isolated from Tetraclinis articulata (Vahl) leaves, which were studied from two different regions that are ecologically various. The average yield of essential oil is 0,56 % for the Ras Elma Tazekka region (mountain) and 0,36% for the Debdou region (plain). An analysis made by GC and GC/ MS identified 22 components in Tetraclinis articulata leaves essential oil in the mountain area and 29 components in the plain area. These major components represent the variability of quantity. The percentages following respectively by the two areas are: Bornyl acetate (34,84%; 32,55%), α-Pinene (11,41%; 18,83%), Camphor (11,24 %; 11,31%), Limonene (11,94 %; 8%) and Borneol (8,35%; 7,79%). The antimicrobial activity of T. articulata essential oil was tested against clinical isolates of Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli which has been inhibited from the 50μg / mL concentration for the Debdou region (Plain) and 25μg / mL for that of the Ras Elma Tazekka region (Mountain).
