In this study, we present a proposal for the physical and chemical quality control of the powder of the species T. parthenium (feverfew) and its hydroalcoholic extract obtained by percolation. The sesquiterpene lactone parthenolide, the main active compound of this plant, was quantifi ed by HPLC and its content was found to be 0.49% in the powder and 1.06% in the extract. The total content of f...

in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

objective(s): as heat, pain is one of the most common clinical symptoms. generally, calcitonin (ct) is prescribed as an analgesic agent for the treatment of pain, especially for the pain caused by osteoporosis or primary and metastatic bone tumor. however, the detailed mechanism remains unknown.materials and methods: in this study, chronic constriction injury (cci) rat model was created, and ho...

Congress grass (Parthenium hysterophorus L., family Asteraceae) is found generally in agricultural and vacant lands across the globe. This study investigated fatty acids elemental profiles of different parts including roots, stem leaves P. response to seasonal variation. The analysis acid were determined both winter summer seasons. root, stem, powder subjected extraction with acetone, water, ch...

The leaves of parthenium (Parthenium hysterophorus L.) were extracted in ethanol and toxicity the extract was examined on khapra beetle (Trogoderma granarium Everts) larvae. Four concentrations (2, 4, 6 8 µL mL-1 acetone) applied directly larvae Petri dishes. Toxicity recorded after 12, 24 36 h. All had considerable effect mortality At highest concentration (8 mL-1), observed 57%, 72% 78% h, re...

The Expressive and the Receptive One Word Picture Vocabulary Test (EOWPVT & ROWPVT). (A combine pilot study in Greek school aged children & data for expressive and receptive language for this population) Tafiadis Dionysios, Augi Bergadi, Xrysanthi Gkrekou, Euaggelia Karagianni, Foteini-Parakseyi Kantakou, Kaliopi Kentioglou, Iosifina Paroutiadou, Konstantina Papageorgiou, Maria Tafiadi, Georgia...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...
