Phylogenetic relationships within Fagonia were inferred from analyses of plastid trnL intron and nuclear ribosomal ITS DNA sequences. Sampling of the genus was nearly complete, including 32 of 34 species. Phylogenetic analysis was carried out using parsimony, and Bayesian model averaging. The latter method allows model-based inference while accounting for model-selection uncertainty, and is her...

The phytotoxicity of the three major monoterpene constituents of the essential oil from leaves of Artemisia scoparia Waldst. & Kit. (redstem wormwood) was investigated. GC/GC-MS analysis revealed that the essential oil (yield 0.84%) is a complex mixture containing 19 monoterpenes, 7 sesquiterpenes and 15 other compounds--aliphatic alcohols, ketones, aromatic hydrocarbons and esters. The three m...

Aqueous extract of Scoparia dulcis could significantly reduce blood sugar levels in white rats which had been previously induced with diabetes by streptozotocin. Extract was administered at doses of 125 and 250 mg/kg body weight/twice a day respectively for a period of 3 weeks. Diabetic rats had much reduced body weight than normal rats. Administration of the extracts at the dose of 250 mg/kg b...

Abstract Indigofera vicioides Jaub. & Spach (Fabaceae) is a paleotropical species and rarely found legume of the Southern India. This was first time it has been recorded in Eastern Ghats Tamil Nadu. article provides detailed description this finding together with images field notes.

Two solid phases of cyclohexane have been investigated over a temperature range spanning 13-266 K on a powdered, perdeuterated sample using neutron total scattering. Phase II has an ordered structure (C2/c) that forms below 186 K. Between 186 and 280 K it exists as a plastic solid-phase I (Fm3m), where the molecules are rotationally disordered about the lattice points of the face-centred cubic ...

The cultivated/domesticated peach (Prunus persica var. persica; Rosaceae, subgenus Amygdalus; synonym: Amygdalus persica) originated in China, but its wild ancestor, as well as where, when, and under what circumstances the peach was domesticated, is poorly known. Five populations of archaeological peach stones recovered from Zhejiang Province, China, document peach use and evolution beginning c...

5-Hexadecenoic acid can be used to produce a semichemical method to control the disease-carrying mosquito Culex quinquefasciatus. This unusual fatty acid is produced in the seed of Kochia scoparia. We have isolated two acyl-acyl carrier protein desaturases from this species and expressed them in Escherichia coli to facilitate functional characterisation.
