Doslidžennâ bìologìčnoï aktivnostìvtorinnogo ekstraktu zì šrotu travimaterinki zvičajnoï (Origanum vulgare)
2015
Studied the antimicrobial activity of secondary extract from oregano herbs waste (Origanum vulgare)against 7 standard test strains of microrganisms. Minimum bactericidal concentration of the extract to Staphylococcus aureus ATCC 6538 P-is 3.125-6.25 mg/ml and 6.25-12.5 mg/ml to gram-negative bacteria and Candida albicans ATCC 10231.Total antioxidant activity determined by DPPH, secondary extract at a concentration of 400 ug/ml was 92 %. The tested extract had photoprotective activity. Obtained results confirm the perspective of using waste of oregano herbs for making extracts and creation on their basis of pharmaceuticals, veterinary drugs and cosmetics.
Chemical composition and biological activity of the essential oil of Ballota hispanica (L.) Benth. growing wild in Sicily
2015
Ballota L. comprises several relevant species largely used for their excellent therapeutic properties. Ballota hispanica (L.) Benth. is widely used in herbal medicine, and it is sold in herbalist shops for its sedative and antispasmodic properties. Considering its traditional medicinal use and the lack of scientific studies on the volatile components of this species as well as on its biological activities, in this study the chemical composition of the essential oil from aerial parts of B. hispanica, collected in Sicily, was evaluated by gas chromatography and gas chromatographyâmass spectrometry. α-Elemol was the most abundant component of the oil (10.9%), followed by α-ylangene (8.5%),…
Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…

The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
