Hypothesis: Genetic variation in plant defence structures a community of herbivores and ultimately mediates co-evolution. Organisms: Common milkweed (Asclepias syriaca) and five natural insect herbivores (seed bug, leaf mining fly, monarch caterpillar and two beetles). Methods: Quantitative genetic field experiment over 2 years, genetic selection analyses, and measurement of five defensive trai...

As part of our ongoing effort to explore the chemical diversity of plants of the United States Midwest region, the isolation and identification of 13 pregnane glycosides named verticillosides A–M from Asclepias verticillata L. are reported. The structures of these compounds were elucidated by various spectroscopic techniques, including 1D and 2D NMR, IR, UV, and HRMS. The cytotoxicity of the is...

Phytochemical investigation of the dried biomass of Asclepias syriaca afforded five new compounds (1-5), along with 19 known structures. Overall, the secondary metabolites isolated and identified from this plant showed a wide structural diversity including pentacyclic triterpenes, cardiac glycosides, flavonoid glycosides, lignans, a phenylethanoid, and a glycosylated megastigmane. In addition, ...

Pulmonary hypertension (PH) is a life-threatening disease that is characterized by elevated pulmonary blood pressure, abnormally thickened pulmonary arteries, and right ventricular hypertrophy. Monocrotaline (MCT) has been used to generate an experimental model of PH in rats, with PH initiated from injuries of lung vascular endothelium. Salvia Miltiorrhiza Bge.f.alba is a widely used traditiona...

http://www.revistadechimie.ro 131 The genus Salvia is one of the largest among the Labiatae genera; it includes over 900 species and has an almost cosmopolitan distribution. Salvia officinalis L. or Dalmatian sage is a perennial low shrub which is native of the western part of the Balkan Peninsula [1]. In Romania, the Salvia genus contains 15 species including Salvia officinalis [2]. According ...

PURPOSE Salvia officinalis L., also known as Maryam Goli, is one of the native plants used to Persian medicinal herbs. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized crude methanol extracts prepared from Salvia officinalis L., on a non-Hodgkin's B-cell lymphoma (Raji) and human leukemic monocyte lymphoma (U937), Human acute myelocytic leuke...

BACKGROUND Severe acute pancreatitis (SAP) and obstructive jaundice (OJ) are frequent recurring diseases that bring about huge threat to human health. Some reports have demonstrated that Salviae miltiorrhizae can protect multiple organs of SAP and OJ model animals or patients, but their related mechanisms were not clear. In this study, we observed the effects of Salvia miltiorrhizae injection o...
