MSc thesis, Chemistry.
In this article we will discuss about the Meaning and Stages of Chemotaxonomy. Meaning of Chemotaxonomy: Chemical systematics is the study of chemical variation in different organisms and their relationships and this approach of taxonomy in which chemical features of plants are used in developing classifications or in solving taxonomic problems is called Chemotaxonomy. Likewise, the prevalence of white lichen in our series was % in the initial lesions. As reported by Eisen, most patients with OLP in our study show no increased prevalence of smoking and/or alcohol use, which do not seem to play a role in the pathogenesis of OLP. Besides, 6 of the present group of patients had family members with a history Cited by:

A lichen is made up of a simple photosynthesizing organism, usually green algae or cyanobacteria, surrounded by filaments of a lly, most of a lichen's bulk is made of interwoven fungal filaments, although in filamentous  and gelatinous lichens this is not the case. The fungus is called a photosynthesizing organism is called a photobiont.

The aim of this work was to study a fast, new, sensitive, and simple method for the chemotaxonomic classification of Chilean lichens (Teloschistes chrysophthalmus, Ramalina farinacea, Usnea pusilla, Ramalina chilensis and Stereocaulon ramulosum) using MALDI-TOF-MS and UPLC-ESI(-)-MS data.
Lichens soluble proteins fingerprints. Mycobiont, forming the major component in lichen thalli is the basis of lichen taxonomy. Lichens are thus regarded as a specialized group of fungi – the Lichenized Fungi (Kirk et al., Author: Hem Chander.

All type strains of species of the genera Deleya and Halomonas, which together comprise the family Halomonadaceae, as well as type strains of the species Alcaligenes aquamarinus, Pseudomonas halophila and Halovibrio variabilis were analysed for their respiratory quinone, polar lipid and fatty acid compositions.

Primary metabolites are produced either by fungal component or by algal component and are meant for the growth and development of the lichen thallus, which are soluble in water.

Introduction. The subcosmopolitan genus Stachys L. comprises more than species and is justifiably considered as one of the largest genera of Lamiaceae (Mabberly, ).Assessed by the number and distribution of the species, two main centers of diversity for the genus in Cited by: Nature which consists of so many variabilities of living components of the environment possesses useful, harmful and inactive chemical constituents.
The classification based on these chemical constituents is known as chemotaxonomy. All the living. A lichen is a composite organism that arises from fruticose), flat leaf-like structures (), flakes that lie on the surface like peeling paint (),  or other growth forms.
 A macrolichen is a lichen that is either bush-like or leafy; all other lichens are termed microlichens.  Here, "macro" and "micro" do not refer to size, but to the growth form.
