Pyrethrum Radix in Alopecia

The antibacterial activity of methanolic Anacyclus pyrethrum and Pistacia lentiscus L. extract on Escherichia coli

BACKGROUND AND OBJECTIVES Antibiotic therapy is the main choice in treatment of Escherichia coli induced infections. Using herbal medication is an alternative choice in treatment of diseases. The aim of this study was to determine the antibacterial activity of two traditionally used herbs in Iranian medicine, Anacyclus pyrethrum and Pistacia lentiscus L., on Escherichia coli. MATERIALS AND ME...

Biosynthesis of Sesquiterpene Lactones in Pyrethrum (Tanacetum cinerariifolium)

The daisy-like flowers of pyrethrum (Tanacetum cinerariifolium) are used to extract pyrethrins, a botanical insecticide with a long history of safe and effective use. Pyrethrum flowers also contain other potential defense compounds, particularly sesquiterpene lactones (STLs), which represent problematic allergenic residues in the extracts that are removed by the pyrethrum industry. The STLs are...

Neuropharmacological Profile of Ethanolic Extract of Anacyclus Pyrethrum in Albino Wistar Rats

The present study was carried out to evaluate CNS activity of ethanolic extract of roots of Anacyclus pyrethrum that includes general behavior studies, sedative, muscle relaxant, anxiolytic, nootropic activity and antidepressant studies in rats. The results reveal potential neuropharmacological activity of Anacyclus pyrethrum as nootropic and also having antidepressant property. Further neuroch...

Analysis of Integral Nonlinearity in Radix-4 Pipelined Analog-to-Digital Converters

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...
