Background: Immune cells perform unique functions against infections and imbalances in immunity associated with various diseases. Applying natural products may control immune responses. Among herbals, much attention has been paid to the immunoregulatory functions of Allium sativum. However, the effects of other Allium species on the immune system have remained undiscovered. Therefore, the curre...

objectives: the aim of present study was to evaluate some effects of crinum zeylanicum (c. zeylanicum) on central nervous system. materials and methods: c. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using irwin test, pentobarbitone-induced sleep test, spontaneous motor activ...

Increasing onion yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the consumers. Two field experiments were carried out during two successive seasons; 2011/2012 and 2012/2013 at the experimental station of National Research Centre, Beheira Governorate (North of Egypt) to find out the influence of some bio-stimulants i.e., yeast extrac...

free radicals involved in a number of diseases due to the oxidative damage to dna, lipids, and proteins and which can result in failure of cellular functions. dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. total antioxidant activities of the methanolic extracts of romulea ramiflora and gagea fibrosa were determined using β-caroten-linoleic acid assay. romulea-bulb...

BACKGROUND Alkaloids present in plants of the Amaryllidaceae family are secondary metabolites of high biological interest, possessing a wide range of pharmacological activities. In the search for new plant-derived compounds with antimicrobial activities, two alkaloid extracts obtained from bulbs and leaves of Pancratium illyricum L., a plant of the Amarillydaceae family, were tested for their e...

AIM The aim of this study was to evaluate the antimicrobial and antioxidant effects of Crinum jagus (J. Thomps.) Dandy methanolic bulb extract in wound healing. MATERIALS AND METHODS Phytochemical screening revealed the presence of alkaloids, glycosides, tannins, and saponins in the extract. In vitro antimicrobial activity of the extract was determined by agar well diffusion method. In vivo a...

A glutathione S-transferase (GST, EC 2.5.1.18) inhibitor was isolated from the onion bulb by fractionation and purification using Sep-pak Vac C18 column, TLC and HPLC. Five partially purified onion bulb GSTs (GSTa and GSTb as minor GSTs, and GSTc, GSTd and GSTe as dominant GSTs) separated by DEAE column were used to detect the inhibitory substance in onion bulb extract. Among the three fraction...
