The quality of dried saffron stigma is highly dependent on the processing and storage conditions. In this study, the effect of different storage conditions (different temperatures, 20, 30 and 40°C along with different water activity, 0.32±0.01, 052±0.01 and 0.75±0.01) of saffron stigma during storage time (12 weeks with two-week time intervals), in both light and dark, on coloring strength, aro...

Assessing mitigation of phosphorus (P) leaching from subsurface drainage systems is challenging due to high spatial and temporal variation in leaching. Mean measured total P leaching from a clayey soil in an eight-year study period (four replicates per treatment) was (kg ha-1 year-1): 1.21 from shallow autumn tillage (ShT), 0.84 from unfertilised fallow (UF), 0.81 from conventional autumn ploug...

the present study was conducted to determine the antioxidant and antifungal effects ofmethanol extract from aerial part of verbascum speciosum. the total phenolic andflavonoid content and the antioxidant activity of the plant extract were determined byusing the folin-ciocalteau and the 2, 2-diphenyl-1-picrylhydrazyl (dpph) free radicalscavenging assays. the total phenols and flavonoid content o...

Introduction: Colchicine, which is derived from a herb called Colchicum medication used to treat gout. itself can act as deadly toxic in the case of over dose. This report study investigates patient who was poisoned with (Soranjan, what it Iran). Description: The 44-year-old man came emergency poisoning ward after day mountaineering and eating Soup.

Background and objectives: Colchicum kurdicum (Bornm.) Stef. is a flowering perennial monocotyledon plant that has many important bioactive compounds especially colchicine and colchicine derivatives. In this study, the ultrasound-assisted acidic-solvent extraction method coupled with response-surface method was presented as the successful method for large scale extract...

BACKGROUND Preparations from anthroposophical medicine (AM) are clinically used to treat inflammatory disorders. We wanted to investigate effects of a selection of AM medications for parenteral use in cell-based systems in vitro. METHODS Colchicum officinale tuber D3, Mandragora D3, Rosmarinus officinale 5% and Bryophyllum 5% were selected for the experiments. Induction of apoptosis and necro...
