The present investigation was carried out to determine the efficacy and safety of Lepidium sativum (L. sativum) (Garden Cress, Fam: Cruciferae) in patients of bronchial asthma. L. sativum seed powder was given at a dose of 1 gm thrice a day orally to 30 patients of either sex in the range of 15-80 years with mild to moderate bronchial asthma without any concurrent medication. The respiratory fu...

The study examines the transfer factor (TF) for cesium in a soil-plant system and cesium accumulation in cress Lepidium sativum L. plants grown in hydroponic culture and subjected to root and foliar application of 0.3 mM CsCl. The experiments showed a high TF for radiocesium: 2.97 (kBq/kg plant DW)/(kBq/kg soil DW). High accumulation of cesium was observed in leaves after both root and foliar t...

A new isoflavonoid, 5,6-dimethoxy-2',3'-methylenedioxy-7-C-β-d-gluco-pyranosyl isoflavone was isolated from the seeds of Lepidium sativum L. along with two known isoflavonoids, 7-hydroxy-4',5,6-trimethoxyisoflavone and 7-hydroxy-5,6-dimethoxy-2',3'-methylenedioxyisoflavone. The structures of all compounds were elucidated with NMR spectrometry. Compounds 1, 2 and the new isoflavonoid 3 were eval...

A cDNA clone for NADPH : protochlorophyllide oxi­ doreductase from barley was subcloned for production of antisense-mRNA. This enabled heterologous hybridi­ zation with RNA from cress seedlings (Lepidium sativum L.). The mRNA level for N A DPH : protochlorophyllide oxidoreductase did not decrease in cress seedlings during irradiation with continuous far-red or white light up to 12 h. The amount...

After removal of myrosinase activity by concanavalin A-Sepharose 4B chromatography, cell-free extracts of light-grown cress (Lepidium sativum L.) seedlings, catalyzed the sulfation of desulfobenzylglucosinolate (K(m), 0.23 millimolar) to benzylglucosinolate using PAPS (K(m), 1 millimolar) as sulfur donor. Sulfotransferase activity, which was optimal at pH 9.0, was stimulated by MgCl(2), MnCl(2)...

Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots.  In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...

Phytotoxic substances released from plants are considered eco-friendly alternatives for controlling weeds in agricultural production. In this study, the leaves of Afzelia xylocarpa (Kurz) Craib. were investigated biological activity, and their active determined. Extracts A. leaf exhibited concentration-dependent phytotoxic activity against seedling length Lepidium sativum L., Medicago sativa Ph...

Reacting active species induced oxidative damage of cellular tissue cause to many human diseases like cancer, cardiovascular disease, nephropathy and aging. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. Recently, attention has focused on phytochemicals as new sources of natural antioxidants. Therefore, the main objective of the prese...
