Phenolic compounds of Urtica cannabina L. (cannabis nettle; family Urticaceae), a widespread Asian species Russia, are poorly studied. In the present study, for first time, chromatographic analysis U. growing in Eastern Siberia was realized together with isolation flavonoids and hydroxycinnamates study biological activity extracts pure compounds. As result, it found that total were characterize...

Abstract Except for a few stick insects that are economically valuable, most species be considered to forest pests, so it is extremely important obtain plant host-use information of more insects. In this paper, the hosts three were recorded first time. We also discovered these can feed upon flowers or leaves plants. Lopaphus unidentatus (Chen & He, 1995) (Phasmida: Lonchodidae) attacked Hyp...

This study was conducted for determining the plant taxa of pollen grain in atmosphere city center Sinop (Turkey) and investigating effects meteorological factors on concentration, by analyzing daily, weekly monthly changes atmosphere. The types amounts were determined using Burkard trap. On basis average 2 years (2016 - 2017), dominant trees Cupressaceae/Taxaceae (32.67%), Pinaceae (15.51%), Mo...

Pollen monitoring is of great importance for the prevention of allergy. As this activity still is largely carried out by humans, there is an ever increasing interest in the automation of pollen monitoring, with the goal of reducing monitoring time in order to plan more efficient treatments. In this context, an original device based on computer vision is developped. In this paper, the colour seg...

Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation of large and otherwise heterogeneous groups. We evaluated the most recent classification with DNA sequences of two regions of the plastid genome, rbcL and trnL-F, from 42 genera of Rhamnaceae and representatives of the related families Elaeagnaceae, Barbeyaceae, Dirachmaceae, Urticac...
