The enzymatic conversion of xanthoxin to abscisic acid by cell-free extracts of Phaseolus vulgaris L. leaves has been found to be a two-step reaction catalyzed by two different enzymes. Xanthoxin was first converted to abscisic aldehyde followed by conversion of the latter to abscisic acid. The enzyme activity catalyzing the synthesis of abscisic aldehyde from xanthoxin (xanthoxin oxidase) was ...

The extracts of Prunella vulgaris L. (Labiatae), a popular Western and Chinese herbal medicine, was shown to have anti-inflammatory properties, which might be due to partially, their rosmarinic acid content. Inhition of prostaglandine E2 (PGE2) production in lipopolysaccharide (LPS) stimulated RAW264.7 mouse macrophage cells was assessed with an enzyme immunoassay (EIA) following 8-hour treatme...

In this study, in vitro antidermatophytic activity against Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis, and Microsporum gypseum was studied by disk diffusion test and assessment of minimum inhibitory concentration (MIC) using CLSI broth macrodilution method (M38-A2). Moreover, antileishmanial and cytotoxicity activity of B. vulgaris and berberine against promastigotes of...

sowing date is the most important factor in physiological and morphological characteristics with positive effects on plants. to evaluate the effect of sowing date and weed interference on yield and yield components of red beans cultivars a factorial split plot experiment in randomized complete block design with three replications was carried out in the research field of zanjan university. main ...
