Daucus carota subsp. maximus (Desf.) Ball from Pantelleria, Sicily (Italy): isolation of essential oils and evaluation of their bioactivity

2021

Daucus is a genus of economically important plants belonging to Apiaceae family spread in temperate regions. Species of this genus are used as food and several biological properties have reported. The chemical composition of the essential oils from different organs (roots, stems and flowers) of Daucus carota subsp. maximus, a species not previously investigated, was analyzed by GC-MS. Our results showed the presence of β-phellandrene as the most abundant component of stems and flowers and of γ-terpinene as a major compound of the oil from the roots. Flower essential oil caused a greater increase in the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) i…

Chemical composition, antioxidant and anticholinesterase activity of the essential oil of algerian cachrys sicula L

2021

In this work, in order to explore a new Algerian medicinal plant used in traditional medicine, the essential oil of the leaves of Cachrys sicula L. (Apiaceae) collected from Algeria, obtained by hydrodistillation, was analyzed by GC/MS. Thirty-two compounds were identified accounting for 98.6% of the total oil, which is characterized by a high content of monoterpene hydrocarbons (74.8%). The main constituents of the essential oil were β-pinene (17.9%), sabinene (17.8%), myrcene (12%), and α-pinene (11.4%). In vitro antioxidant activity of the essential oil was assayed by three methods, namely ABTS•+, metal chelating, and DPPH• assays. The antioxidant activity of the oil was higher in the AB…

Chemical composition, antimicrobial and antioxidant activity of the essential oils from Pimpinellatragium Vill. subsp. glauca (C. Presl.) C. BrulloBr…

2013

The essential oils from flowers, leaves and stems hydrodistilled from Pimpinella tragium Vill, subsp. glauca were characterised by GC and gas chromatography-mass spectrometry analysis. The C-12 nor-sesquiterpenes are the principal class of metabolites (56.6-70.6%) among which geijerene (28.9÷49.3%) and pregeijerene (10÷19.1%) predominate. Antimicrobial and antioxidant activities were evaluated. The minimum inhibitory concentration values indicate that oil obtained from the stems is the most active for antimicrobial activities and the sample with the biggest antioxidant capacity is the flower oil.

Antimicrobial and antiproliferative activity of Athamanta sicula L. (Apiaceae).

2010

Background: Athamanta sicula L., a member of Apiaceae, is an annual perennial herb and it is known in Sicilian popular medicine with the name of “spaccapietre” (rock splitters), because fresh roots infusions are indicated as diuretic and used in the treatment of diseases of the urinary tract, and to dissolve kidney stones. Materials and Methods: Acetone extracts of leaves, flowers, and stems of A. sicula L. were investigated in vitro for antibacterial and cytotoxic activities. Antimicrobial activity was carried out against bacterial and fungal strains and antiproliferative activity against a group of human cancer cell lines (K-562, NCI-H460, and MCF-7). Results: All acetone extracts, apiol …

Phytochemical investigation and antitumor activity of coumarins from Sicilian accession of Ferulago nodosa (L.) Boiss. roots

2023

Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area being present in Crete, Greece, Albania, and probably in Macedonia. From the roots of this accession of species, not previously investigated, four coumarins, grandivittin, aegelinol benzoate, felamidin and aegelinol, and two terpenoids, (2E)-3-methyl-4-[(3-methyl-1-oxo-2-buten-1yl)oxy]-2-butenoic acid and pressafonin-A, were isolated and spectroscopically characterized. The last one was never detected in Ferulago species. The evaluation of the anti-tumor effects of F. nodosa coumarins on colon cancer HCT116 cells showed only a modest effect on reduction of tumor cell viability. For aegelinol, the red…

Vēlā dzelzs laikmeta un viduslaiku sākuma posma skeletkapi Ziemeļkurzemē (9.-14.gs.)

2015

Bakalaura darba mērķis ir izvērtēt un analizēt apbedīšanas tradīcijas un apbedīto etnisko piederību 14 arheoloģiski pētītos vai apzinātos Ziemeļkurzemes kapulaukos ar skeletapbedījumiem- no tiem 11 ar vēlo dzelzs laikmetu datētos (11.-12.gs.) Baltijas somu un trijos ar viduslaiku sākumposmu datētos (13.-14.gs.) kapulaukos. Pētījuma gaitā tiek apstiprināta tēze, ka vismaz astoņos kapulaukos - Tukuma Jaunajā tirgus laukumā, Mežītē, Lībagu Kalneniekos, Laidzes Pēčos, Matkules Lanksēdē, Virbu Zunnās, Lībagu Ķīļos, un Lībagu Lejaslāčos, domājams, ir apbedīti vendi laikposmā no 11.gs. beigām līdz 12.gs. Trīs kapulaukos apbedīto etnisko piederību ar līdzšinējām liecībām konstatēt nav iespējams, be…

A adaptação marginal do MTA em dentes imaturos = Adaptación marginal del MTA en dientes inmaduros

2015

Quando dentes com formação incompleta da raiz sofrem necrose pulpar, devido a trauma ou cárie, o desenvolvimento radicular é interrompido e consequentemente o canal permanece amplo com paredes finas e frágeis e o apex mantém-se aberto. O “plug” apical ou barreira apical artificial através da colocação de MTA (Agregado Trióxido Mineral) tem sido sugerida, como alternativa à tradicional apexificação com Ca(OH)2. Não se sabe, no entanto, dada a grande variabilidade no diâmetro dos canais e em particular no apex, qual a influência desse diâmetro apical na capacidade de selamento do MTA e na sua adaptação às paredes radiculares, quando este material é utilizado para promover a barreira apical. E…

Demonstration of a correlation between young leaves, apex and young bunches specific to a young grapevine cutting in the first period of its developm…

2001

<p style="text-align: justify;">The development of hardwood cutting of grapevine comprise 4 succesive phases. Phase I: first period of shoot extension. Phase II: characterized by a slow growth due to a very low activity of the terminal bud. Phase III: reactivation of the growth consecutive to a resumption of the apical activity. Phase IV: when the growth becomes maximal.</p><p style="text-align: justify;">The objective of this work has been to identify the cause of the slowdown of the activity of apical bud during the phase II.</p><p style="text-align: justify;">In a first experiment, we have compared the effects of three modes of defoliation applied from the b…
