Pleistocene Infraspecific Evolution in Juniperus Ashei Buch
The Pleistocene and recent distributions of the taxa are discussed. A new variety of Juniperus ashei, J. ashei Buch. var. ovata R. P. Adams is recognized from west Texas and northern Mexico. It differs from typical J. ashei in having whip leaf glands that are oval to elongate rather than hemispherical, smaller female cones, smaller seeds and more seeds per cone. In addition, the leaf oil of var...
متن کاملStudy of the hepatoprotective effect of Juniperus phoenicea constituents.
Different fraction obtained from the aerial parts of Juniperus phoenicea showed significant activity as hepatoprotective when investigated against carbon tetrachloride induced liver injury. The hepatoprotective activity was evaluated through the quantification of biochemical parameters and confirmed using histopathology study. Phytochemical investigation of the petroleum ether, chloroform and m...
متن کاملAntiparasitic, nematicidal and antifouling constituents from Juniperus berries.
A bioassay-guided fractionation of Juniperus procera berries yielded antiparasitic, nematicidal and antifouling constituents, including a wide range of known abietane, pimarane and labdane diterpenes. Among these, abieta-7,13-diene (1) demonstrated in vitro antimalarial activity against Plasmodium falciparum D6 and W2 strains (IC(50) = 1.9 and 2.0 microg/mL, respectively), while totarol (6), fe...
متن کاملDifferences in chemical composition between browsed and non-browsed Juniperus ashei Buch. Trees
Leaf secondary compounds were examined in browsed and non-browsed Juniperus ashei trees to identify selective browsing patterns by goats and deer. Analysis of volatile leaf oils (terpenoids) revealed that the browsed trees were lower in total oil than non-browsed trees (2.18 vs. 3.46%, DW basis). Extractable and fiber-bound condensed tannins (CT) were not different but protein-bound CT concentr...
متن کاملInsecticidal Constituents and Activity of Alkaloids from Cynanchum mongolicum.
Based on MS and NMR data and bioassay-guided tracing, three insecticidal alkaloids I, II and III from Cynanchum mongolicum were identified to be antofine N-oxide, antofine and tylophorine. Alkaloid I was more toxic than alkaloids II and III, but they were less active against Spodoptera litura than total alkaloids. The contact toxicity from these alkaloids against the aphid Lipaphis erysimi was ...
