Essential oil composition of Tordylium apulum L. from Italy
No full textThe essential oil composition of aerial parts of Tordylium apulum L. from Italy was analyzed by GC and GC/MS. Sixty-seven compounds were identified representing 96.5% of the oil. The most abundant compounds were (E)-β-ocimene (17.3), α-humulene (11.4%) and octyl octanoate (8.8%)
Su un raro reperto di mesotelioma in un cinghiale
No full textIl mesotelioma, neoplasia pleurica o addominale di variegata morfologia, è stato segnalato a più riprese nel cane e descritto anche nel cavallo, nel bovino e, sporadicamente nel maiale domestico. Sulla base della bibliografia consultata, la neoplasia risultava sconosciuta negli animali selvatici; abbiamo pertanto ritenuto interessante descrivere, in questa nota, un caso di mesotelioma addominale osservato su un cinghiale sardi vissuto allo stato selvatico

Essential oil composition of different aerial parts of Pistacia terebinthus L. growing wild in Sardinia
No full textEssentials oils from different aerial parts of Pistacia terebinthus L. growing wild in Sardinia were analyzed in a single GC and GC/MS run. The oil yields obtained from the different parts range from 0.01-1.5%. alpha-Pinene was the main constituent of each of the P. terebinthus oils with the twig oil containing the highest concentration of 66.0%. In fruitful twigs the alpha-pinene concentration was 54.8% while in the leaf oil it was 16.4%. The other major component was beta-pinene, the level of which in the oils of fruitful twigs and leaves was 22.5% and 13.5%, respectively.Essentials oils from different aerial parts of Pistacla terebinthus L. growing wild in Sardinia were analyzed in a single GC and GC/MS run.

della depressione (2-3) abbiamo ritenuto interessante indagare la specie spontanea presente in
Sardegna. Le analisi sono state effettuate via HPLC
Chemical composition of Thymus serrulatus Hochst. ex Benth. essential oils from Ethiopia: a statistical approach
No full textFrom the essential oil (EO) obtained from the aerial parts of T. serrulatus collected in Ethiopia, fifty-three compounds were
identified by GC/MS, accounting for more than 99% of the total volatile fraction. Thymol and carvacrol were the main
compounds, ranging from 10.0 + 0.9 to 43.8 + 3.8% and 4.5 + 0.4 to 39.1 + 3.8%, respectively, of the total. o-Cymene, γ-
terpinene, and linalool were the most representative compounds in all the EOs
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
