Medicinal plants are valuable and used for the synthesis of numerous drugs. Indigenous plants are traditionally used against various ailments. Present work is based on the research conducted on methanolic crude plant extracts of three medicinal plants of family solanaceae i.e. leaves of Datura inoxia Mill., Withania somnifera (L.) Dunal and Solanum surrattense were screened to investigate the b...

Datura stramonium is a widely used poisonous plant with great medicinal and economic value. Its chloroplast (cp) genome is 155,871 bp in length with a typical quadripartite structure of the large (LSC, 86,302 bp) and small (SSC, 18,367 bp) single-copy regions, separated by a pair of inverted repeats (IRs, 25,601 bp). The genome contains 113 unique genes, including 80 protein-coding genes, 29 tR...

Availability of complete plastid genomes of ten solanaceous species, Atropa belladonna, Capsicum annuum, Datura stramonium, Nicotiana sylvestris, Nicotiana tabacum, Nicotiana tomentosiformis, Nicotiana undulata, Solanum bulbocastanum, Solanum lycopersicum, and Solanum tuberosum provided us with an opportunity to conduct their in silico comparative analysis in depth. The size of complete chlorop...

The aim of this work was to investigate and compare the phytochemical screening and antimicrobial activities of different crude extracts from dry and fresh leaves of Datura metel. Different organic solvents including methanol, chloroform, hexane, ethyl acetate and butanol were used to prepare the crude extracts from the fresh and dry leaves. Antimicrobial activities of different crude extracts ...

An enzyme system from Datura innoxia roots oxidizing formylphenylacetic acid ethyl ester was purified 38-fold by conventional methods such as (NH4)2SO4 fractionation, negative adsorption on alumina Cy gel and chromatography on DEAE-cellulose. The purified enzyme was shown to catalyse the stoicheiometric oxidation of formylphenylacetic acid ethyl ester to benzoylformic acid ethyl ester and formi...

The aim of the present study was to investigate the antimicrobial activity and phytochemical screening of Carica papaya, Piper nigrum and Datura stramonium plant extracts. Ethanol and Methanol were used as the solvents for extraction. The antimicrobial activities of these plant extracts were tested against the drug resistant Gram-positive and Gram-negative bacterial strains. The bacteria used i...

A wild-type Datura innoxia cell line (Px4) was used to select methotrexate-resistant cells through a stepwise procedure. Two independently selected cell lines, MTX161 and MTX132, were stable and shown to be 5 to 15 times more resistant to methotrexate than wild type. These methotrexate-resistant cells were similar to the wild-type cells in levels and kinetic properties of dihydrofolate reductas...

Microcomplement fixation was employed to compare the immunological differences that occur between purified inhibitor I from potato tubers, the four purified protomers that comprise it, and inhibitor I from tuber and leaf extracts. Total inhibitors of chymotrypsin and trypsin in leaves of seven genera of the Solanaceae were identified by enzymatic assay. In leaves of three genera, Solanum, Lycop...

When plants are introduced into new regions, the absence of their co-evolved natural enemies can result in lower levels of attack. As a consequence of this reduction in enemy pressure, plant performance may increase and selection for resistance to enemies may decrease. In the present study, we compared leaf damage, plant size and leaf trichome density, as well as the direction and magnitude of ...

Introduction: Opposite observations about the discrepancy in the pain perception between male and female has been reported. In this regard, pain thresholds among male and female rats in different phases of oestrous cycle were evaluated via tail immersion test. In addition, efficiency of alcoholic extract of datura stramonium as an analgesic plant in the modulation of acute pain threshold has be...
