Euphorbia ebracteolata Hayata (E. ebracteolata) is a Chinese herbal medicine used for the treatment of tumor diseases. An ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) based chemical profiling approach was established for the rapid separation and characterization on phloroglucinol derivatives and diterpenes in E. ebracteolata. Three phlorogl...
Antioxidant activity of the ethanolic extract and fractions from the stem bark of T. catigua was investigated. IC₅₀ (for DPPH scavenging) by T. catigua varied from 9.17 ± 0.63 to 76.42 ± 5.87 mg mL⁻¹ and total phenolic content varied from 345.63 ± 41.08 to 601.27 ± 42.59 mg GAE g⁻¹ of dry extract. Fe²⁺-induced lipid peroxidation was significantly reduced by the ethanolic extract and fractions. ...
Gülnar (Mersin)’da elma ağaçlarında bulunan zararlı ve yararlı Arthropoda türlerini saptamaya yönelik olarak yapılan bu çalışma 2014-2015 yıllarında ilkbahar, yaz sonbahar periyotlarında sürdürülmüştür. Çalışma sonucunda, 26 13 tür tespit edilmiştir. En önemli türlerin; Panonychus ulmi (Koch, 1836), Aphis pomi DeGeer, 1773, Eriosoma lanigerum (Hausmann, 1802), Tropinota hirta (Poda, 1761) Cydia...
Plants, phytophagous insects and their parasitoids form the most diverse assemblages of macroscopic organisms on earth. Enclosed in particular represent a tractable system for studying community assembly diversification. Communities associated with widespread plant species are especially suitable as they facilitate comparative approach. Pantropical fig-wasp communities remarkably well-replicate...
Dissolution is one among several taphonomical processes that may bias paleoenvironmental, paleoclimatic or taxonomic interpretation of phytolith assemblages. To improve our understanding dissolution on grass phytoliths, we studied systematic changes surface features, morphotype assemblages, and rates phytoliths extracted from two species Hyparrhenia involucrata (Panicoideae), Nastus borbonicus ...
Stampfli A. 1992. Effects of mowing and removing litter on reproductive shoot modules of some plant species in abandoned meadows on Monte San Giorgio. Bot. Helv. 102: 85-92. Reproductive shoot modules have been counted in a permanent plot experiment on Monte San Giorgio (Southern Switzerland) since 1988. The 8 species presented here, including the dominant grass (Molinia arundinacea) and seven ...
