The objective of this study was to examine the in vitro and in vivo antioxidative properties of aqueous and ethanolic extracts of the leaf of Nasturtium officinale R. Br. (watercress). Extracts were evaluated for total antioxidant activity by ferric thiocyanate method, total reducing power by potassium ferricyanide reduction method, 1,1-diphenyl-2-picrylhydrazyl (DPPH*) radical scavenging activ...

The aim of the present study is to evaluate the antioxidant and proliferative effects of aqueous and ethanolic extracts of Symphytum officinale. Antioxidant activities of extracts were determined by 2,2diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, superoxide radical scavenging and Folin-Ciocalteu assays. Proliferative effects of the extracts were evaluated on 3T3 Swiss albino mouse fibro...

ginger plant, zingiber officinale roscoe, is an important tropical plant used as spices and well known for its medicinal properties. it has a pungent and aromatic rhizome rich of zingiberen and gingerols. many secondary metabolites are known to accumulate in the plant cell culture systems. so, in this research, gingerols and zingiberene production of callus cultures were compared with regenerat...

objective(s):the use of doxorubicin (dox) is limited by its dose-dependent cardio toxicity in which reactive oxygen species (ros) play an important role in the pathological process. the aim of this study was to evaluate the protective effect of three medicinal plants, nigella sativa (n), glycyrrhiza glabra (g) and zingiber officinale (z), and their combination (ngz), against dox-induced apoptos...

spasmolytic, antioxidant, anti-inflammatory and immuno-modulatory properties of ginger (rhizome of zingiber officinale roscoe) suggest that it may has beneficial effects on inflammatory bowel diseases. in the present study, the effect of this herbal extract on a model of acute colitis was evaluated. ginger hydroalcoholic extract with doses of 150, 350, 700 mg/kg, prednisolone (2 mg/kg), or vehi...

The main British population of Gortyna borelii occurs on the north Essex coast, on sites very close to sea level. During 1999, 2000 and 2001, ovipositing strategies of G. borelii were studied providing details of egg laying behaviour, preferred oviposition host plants, height of ova deposition and distance of the oviposition site from the nearest larval food plant (Peucedanum officinale). Six o...

The effectiveness of aqueous extract of seven locally available medicinal plants i.e. Trachyspermum ammi (seeds), Zingiber officinale (rhizome), Tinospora cordifolia (leaves), Cymbopogon citratus (leaves), Moringa oleifera (bark) were evaluated against the plant pathogenic fungus i.e. Fusarium oxysporum f. sp. lini (causing wilt in linseed). The plant extracts were screened for their antagonist...

Dendrobium Officinale is the rare Chinese herbal medicine. This paper will introduce its low cost grade determining system research mainly from the following two aspects: First of all, choose low cost CCD to do image capture, apply machine vision algorithm to extract the stem edge image, and automatically determine the stem diameter size and determine the uniformity coefficient of its size; Sec...
