Hairy root culture plays an important role in investigation of alkaloid production in culture in vitro. The complexity of scientific work and the production capacity limitations associated with whole plant systems and unorganized cells can be overcome using culture of hairy roots. This paper presents an example of a strategy to produce secondary metabolites from plants, in which we investigated...

The attention of the profession in this country, was not, I believe, particularly called to the medicinal properties of the Stramonium till Dr Marcet, in an interesting paper, read before the Medical and Chirurgical Society of London, in June 1816, and published in their Transactions *, detailed the ^results of his experience of its use. Storck, it is true, so early as 1762, in a pamphlet publi...

The alkaloid spectra of Datura innoxia plants grown in Egypt and Bulgaria were investigated by GC-MS. Thirty-eight alkaloids were detected in the roots, leaves and fruits of the plants. Five new alkaloids for D. innoxia are reported. Alkaloid spectra of Egyptian and Bulgarian plants differ significantly in respect to their alkaloid composition and main alkaloids accumulated in the plant organs.

In the tomato (Lycopersicon esculentum) plant, the fruit juice was found to be the richest source of agglutinating activity. The lectin responsible could be inhibited by oligomers of N-acetylglucosamine, and this property was exploited to purify the lectin by affinity adsorption on trypsin-treated erythrocytes. The lectin is a glycoprotein that cross-reacts immunologically with the lectin from ...

Phytochemical screening of various fractions of Datura alba showed bioactive secondary metabolites based on microbial and antioxidant activities. n-Hexane fraction showed a significant activity against three selected bacterial strains; Bacillus subtilis, Klebsiella pneumoniae and Staphylococcus aureus while other isolated fraction showed moderate activity. The ethyl acetate (88.89 %) and methan...

pattern by making it difficult to delimit sectors clearly. Although the data at hand precluded the possibility of making rigorous comparisons between plants arising from seed subjected to thermal neutrons and plants from x-irradiated seed, no developmental or morphological disturbances or lethality patterns in Datura unique to either kind of treatment were detected. Caldecott, Frolik, and Morri...

The uptake and biotransformation of TNT was studied in cell suspension cultures and in whole plants of Datura innoxia and Lycopersicon peruvianum. In cell culture, TNT was rapidly removed from the growth medium and recovered from the cell extract in the form of a variety of biotransformation products resulting from nitroreduction, deamination, Nacetylation and side chain oxidation to aldehyde a...

Twenty-four yeast strains were isolated from ephemeral flowers of Ipomoea spp. and Datura sp. and their associated insects in the Galápagos Archipelago, Ecuador, and from Ipomoea spp. and associated insects in the Cameron Highlands, Malaysia. Sequences of the D1/D2 domains of the large subunit rRNA gene indicated that these strains belong to a novel yeast species of the Kodamaea clade, although...

A 12 year old boy presented with an acute onset of anisocoria and blurred vision. Ocular motility was normal but his right pupil was dilated, round but sluggishly reactive to light. There was no history of trauma, eye drops' instillation, nebulised drugs or local ointments. His past medical history was negative.A third nerve palsy was considered but the performed cerebral MRI was normal.On furt...
