The inhibitory effect of galloyl pedunculagin (GP) isolated from Platycarya strobilacea on the activity and autophosphorylation of Ca(2+)- and phospholipid-dependent protein kinase (C-kinase) was examined in vitro. It was found that (i). GP inhibited the activity (phosphorylation of complement C3 from guinea pig) of C-kinase alpha (rat brain) in a dose-dependent manner with an ID(50) of approx....

Changes in slope aspect have important effects on the C, N and P nutrient contents stoichiometric characteristics of plants soils. As an forest type subtropical region, Pinus massoniana forests play role restoration development ecosystems. In this study, effect stoichiometry leaves soils four P. types (i.e., pure (PF), massoniana-Liquidambar formosana mixed (PLM), - Platycarya strobilacea (PPM)...

Background and objectives: The genus Ephedra (Ephedraceae) consists of about 40 species of mostly shrubs and rarely small trees around the world. In the present study, the essential oil (EO) diversity and genetic relationships were investigated in six Ephedra species from Iran using Random Amplified Polymorphic DNA (RAPD) markers. Methods: The plants were collected from two different provinces;...

When measuring plant functional traits across geomorphologies, 5–10 healthy individuals of a species are commonly sampled. However, whether more should be sampled in habitat-heterogeneous karst vegetation remains unknown. In this study, two dominant tree ( Clausena dunniana and Platycarya strobilacea ) evergreen broadleaved mixed forests Southwestern China were selected. On the basis large quan...
