Lepidium sativum is widely used in folk medicine for treatment of hyperactive airways disorders, such as asthma, bronchitis and cough. The crude extract of Lepidium sativum (Ls.Cr) inhibited carbachol (CCh, 1 μM-) and K(+) (80 mM-) induced contractions in a pattern similar to that of dicyclomine. Ls.Cr at 0.03 mg/mL produced a rightward parallel shift of CCh curves, followed by nonparallel shift at higher concentration (0.1 mg/mL), suppressing maximum response, similar to that caused by dicyclomine. Pretreatment of tissues with Ls.Cr (0.1-0.3 mg/mL) shifted Ca(++) concentration-response curves (CRCs) to right, as produced by verapamil. Ls.Cr at low concentrations (0.03-0.1 mg/mL) caused leftward shift of isoprenaline-induced inhibitory CRCs, like that caused by rolipram, a phosphodiesterase (PDE) inhibitor. These results indicate that bronchodilatory effect of Lepidium sativum is mediated through a combination of anticholinergic, Ca(++) antagonist and PDE inhibitory pathways, which provides sound mechanistic background for its medicinal use in the overactive airways disorders.

Twelve flavonoid glycosides including five undescribed ones, lepisativutimines Q-U, were isolated and identified from Lepidium sativum seeds. Acid hydrolysis followed by acetic derivatization and GC analysis were conducted to determine the absolute configurations for sugars. Lepisativutimine U and beitingxinhuangtong A were uncommon kaempferol 8-S-glycosides, and complete NMR data of beitingxinhuangtong A were provided for the first time.

The influx of insufficiently purified or untreated domestic wastewater into aquatic ecosystems raises the question of the production of environmentally friendly detergents. The purpose of this work was to investigate the toxicity of phosphonate-containing and phosphate-free dishwashing detergents for dishwashers according to the phytotest with a garden cress ( L.).

This study reports the isolation and characterization of highly resistant bacterial and microalgal strains from an Egyptian wastewater treatment station to cyanide-containing compounds. The bacterial strain was identified as Bacillus licheniformis by 16S rRNA gene sequencing. The isolate removed up to 1 g L potassium cyanide, 3 g L benzonitrile, and 1 g L sodium salicylate when incubated as 10% v/v in MSM at 30 ℃.
