An Evaluation of the Chemotaxonomy of Lignosus Rhinocerus
Chemotaxonomy is the classification of plants and microorganisms based on similarities and differences in their natural products and the biochemical pathways involved in their manufacture. The classification and identification of L rhinocerus, a medicinal fungus, for this research was based on …

The chemotaxonomy of the fungal genus Endothia fr.
The taxonomic status of the fungal genus <i>Endothia</i> was recently changed in a controversial monograph by Barr (Barr, M. E. 1978. The Diaporthales of North America. Mycol. Mem. 7. J. C. Cramer. 232 p.), who divided the genus into two separate genera, <i>Endothia</i> and <i>Cryphonectria</i>, …

Determination of a robust metabolic barcoding model for chemotaxonomy in Aizoaceae species : expanding morphological and genetic understanding
The use of metabolic fingerprints as taxonomic markers is becoming more common. Many studies have found that by comparing the vast metabolic fingerprints of closely related species to each other, secondary metabolites tend to be unique to the samples of individual species and are identified in …

The characterisation of actinomycetes isolated from diverse South African sources, with emphasis on the genus Kribbella
… A polyphasic approach combining physiology, chemotaxonomy and phylogenetic analysis was used to characterise these isolates. A number of potentially novel strains belonging to the rarer genera were identified, including two Kineococcus and three Micromonospora strains. Two novel Kribbella …

Pharmacognosy of the Saururaceae : microscopy of powdered drugs
… of some plants of this family and their chemotaxonomy has been investigated in our laboratory (12).</p> <p>It is very difficult to establish identity and authenticity of commercially available crude drugs and powders of the Saururaceae because a detailed, collective study of microscopic …

An evaluation of free amino acids as chemotaxonomic markers in Protea L. species
… towards the classification of plants by applying chemotaxonomy or chemosystematics, whereby chemical evidence is incorporated with morphological and other information. The genus Protea L. was an obvious choice for the initial material of such research as it is one of the best-known and most …

An Evaluation of the risks to food safety and shellfish farming in Great Britain,posed by marine biotoxins from, current and future emerging, marine microalgal species
… work determined a mechanism for the use of chemotaxonomy to differentiate the source of shellfish intoxications, allowing for separation of two key GB saxitoxin producers, A. minutum and Alexandrium catenella. This technique could enhance routine monitoring data with little additional cost. …

A biosystematic study of Allium amplectens Torr
This investigation attempts to verify the identification of the anthocyanin in A. amplectens by spectral means. An attempt was also made to identify the sugars, and possibly their locations on the heterocyclic ring system, of the anthocyanins.

Chemotassonomia e attività biologica degli oli essenziali di taxa del genere Thymus.
Il lavoro di ricerca prende spunto dalle problematiche tassonomiche inerenti al genere Thymus correlate alla notevole variabilità dei tratti morfologici spesso non sufficientemente discriminanti. Lo studio ha riguardato la caratterizzazione dei componenti chimici degli oli essenziali di differenti …
