Efficacy of sea fennel (Crithmum maritimum L., Apiaceae) essential oils against Culex quinquefasciatus Say and Spodoptera littoralis (Boisd.)
2017
The effective management of insect pests and vectors still represents a major challenge in current entomology. Culex quinquefasciatus Say is a key vector of lymphatic filariasis, Rift Valley fever, West Nile, St. Louis encephalitis and Western equine encephalitis virus. Recently, the importance of the eco-friendly control of C. quinquefasciatus larval population using plant-borne biopesticides, including essential oils (EOs), has been stressed. Spodoptera littoralis (Boisd.) also known as tobacco cutworm, is one of the most destructive moth agricultural pests in tropic and sub-tropic regions. Despite the fact that sea fennel (Crithmum maritimum L., Apiaceae) is considered as a promising bio…
Comparative analysis and antimicrobial action of some essential oils from plants
2021
In this research, essential oils (EOs) were extracted through steaming from aerial parts of three plants: basil (Ocinum basilicum L.), peppermint (Mentha piperita L.) and oregano (Origanum vulgare L.) form Sibiu County, Romania. The GC-MS analysis indicated that eugenol and apiol were the major compounds in the basil EO. Timol, ɣ-terpinene, and p-cymene were the major compounds in the volatile oil extracted from oregano and menthol and methone the main components in the peppermint EO. In the first 48 h of analysis, basil EO inhibition action was the highest against Salmonella anatum (48%), followed by Aspergillus niger (26%), Bacillus cereus (21%) and Saccharomyces cerevisiae (15%); this ac…
Chemical Composition of the Essential Oil ofAnethum graveolensAerial Parts
2014
Abstract:The chemical composition of the essential oil obtained by hydrodistillation method from the aerial parts of Anethum graveolens were analysed by GC-MS. Twelve compounds constituting 96.8 % of the oil were identified. The main compounds were α-phellandrene (31.8 %), apiole (15.3 %), dill ether (13.2 %), limonene (11.8 %), geraniol (10.6 %) and pcymene (5.3 %). The chemical composition of the oil was found to be similar as reported from India and abroad, however there was a considerable quantitative variation among the major compounds identified.
Omistaja-asiakkaiden kokemus Tapiolan yritysvastuusta
2012
Yritysten yhteiskuntavastuun merkitys kasvaa jatkuvasti ja vastuullisuudesta viestiminen tullut yhä tärkeämmäksi yrityksille. Vastuuviestinnällä halutaan kertoa yrityksen toimista vastuullisuuden saavuttamiseksi siitä kiinnostuneille. Tässä tutkimuksessa selvitettiin Tapiola ryhmän vastuuviestinnän näkyvyyttä ulkoisille sidosryhmille, tarkemmin määriteltynä neuvottelukuntien jäseninä oleville omistaja-asiakkaille. Tutkimusongelmana oli miten omistaja-asiakkaat neuvottelukunnissa kokevat Tapiolan vastuullisuusviestinnän. Tätä ongelmaa lähdettiin ratkaisemaan asettaen tarkentavia tutkimuskysymyksiä kuten; miten omistaja-asiakkaat kokevat Tapiolan vastuullisuuden? Miten omistaja-asiakkaat koke…

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 …
