The essential root oils of the Pimpinella saxifraga subspecies eusaxifraga, alpestris and nigra were investigated by means of capillary GC and spectroscopic methods. A total of 48 components was identified. Characteristic constituents of all oils are pseudoisoeugenol derivatives, sesquiterpenoids and trinor-sesquiterpene hydrocarbons, but the qualitative and quantitative patterns of the individ...

Recently we reported the comparative studies on the production and accumulation of phenylpropanoids in plants and in cell cultures of anise [1, 2]. It was shown that cell cultures did not produce anethole, the main constituent in the fruit oil of anise, but instead regularly epoxy-pseudoisoeugenol(2-methylbutyrate). We first identified this unusually substituted phenylpropanoid in the root of P...

AIM To compare the antibacterial effect of hydro alcoholic extract of Salvia officinalis, Pimpinella anisum, Satureja hortensis, Rhus coriaria, Carum copticum, Mentha longifolia, Achillea millefolium against Streptococcus mutans, Lactobacillus rhamnosus and Actinomyces viscosus through two in vitro methods. METHODS In this experimental study, hydro-alcoholic extracts have been prepared from t...

The alien invasive Gambusia affinis is one of the most widely introduced fish species on the planet, and has established in freshwater ecosystems across South Africa. The invasion ecology and, in particular, the population dynamics of the species in this country are, however, poorly understood. In this study the relative abundance and population dynamics of G. affinis were quantified in 5 inter...

Mysoria wilsoni H.A. Freeman, 1969, is established as a new junior synonym of Mysoria affinis (HerrichSchäffer, 1869). A lectotype for Pyrrhopyga [sic] affinis Herrich-Schäffer, 1869 is designated.

The first study of the aphid fauna from Chukotka Autonomous Okrug has been made; 18 species are reported from this territory, the most north-eastern of Russia and of the Palaeartic Region. Five new species are described: Aphis aquilonalis sp. nov. on Rumex arcticus Trautv.; Aphis beringiensis sp. nov. were collected by yellow trap; Macrosiphoniella (Asterobium) jaroslavi sp. nov. on Artemisia a...

In the present study, the antioxidant and antimicrobial effects of essential oil (EO) and extract of Pimpinella affinis on the shelf life of rainbow trout during storage at refrigerator temperature based on three indicators of microbial, chemical and sensory quality parameters were evaluated. For this purpose, fish samples were stored in zein coatings containing 1.00% EO and 2.00% extr...

Predation is a dominant and influential factor in most ecological communities. However, little is known about how the federally endangered Barton Springs Salamander, Eurycea sosorum, responds to predators. Using captive-hatched (predator-naı̈ve) salamanders, we examined the antipredator response of E. sosorum to chemical cues from (1) native Western Mosquitofish (Gambusia affinis), (2) introduce...

The aim of this study was to screen 15 essential oils of selected plant species, viz. Lavandula angustifolia, Carum carvi, Pinus mungo var. pulmilio, Mentha piperita, Chamomilla recutita L., Pinus sylvestris, Satureia hortensis L., Origanum vulgare L., Pimpinella anisum, Rosmarinus officinalis L., Salvia officinalis L., Abietis albia etheroleum, Chamomilla recutita L. Rausch, Thymus vulgaris L....

We experimentally investigated the effects of different pre-treatments of the sediment, and the effect of daily addition of fresh phytoplankton, on the growth and survival of 1-year-old (1+) individuals of the deposit feeder Monoporeia affinis (Amphipoda). We used three different types of sieved sediment: pre-frozen muddy clay, non-pre-frozen muddy clay, and fine sand. The muddy clay contained ...
