Phytochemical techniques raman pdf

Phytochemistry is a rapidly expanding area with new techniques being developed and existing ones perfected and made easier to incorporate as standard methods in the laboratory. This latest edition includes descriptions of the most up-to-date methods such as HPLC and the increasingly sophisticated NMR and related spectral techniques.

Other methods described are the use of NMR to locate substances within the plant cell and the chiral separation of essential oils. After an introductory chapter on methods of plant analysis, individual chapters describe methods of identifying the different type of plant molecules: phenolic compounds, terpenoids, organic acids, lipids and related compounds, nitrogen compounds, sugar and derivatives and macromolecules.

Different methods are discussed and recommended, and guidance provided for the analysis of compounds of special physiological relevance such as endogenous growth regulators, substances of pharmacological interest and screening methods for the detection of substances for taxonomic purposes. It also includes an important bibliographic guide to specialized texts. This comprehensive book constitutes a unique and indispensable practical guide for any phytochemistry or related laboratory, and provides hands-on description of experimental techniques so that students and researchers can become familiar with these invaluable methods.

Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. Phytochemical Methods: A guide to modern techniques of plant analysis.

Phytochemical analysis of biologically active constituents of medicinal plants. Plants are a source of many drugs such as antispasmodics, emetics, antimicrobials, antipyretics, antidiarrheals, antioxidants, and antitumor agents.

A large number of the plants are claimed to … Expand. View 1 excerpt, cites background. Ethno medicine is the oldest method of curing diseases and infections. Various plants have been used in different parts of the world to treat human diseases and infections.

H2SO4 was added carefully along the sides of the test tube. The red colour was produced, indicating the presence of sterols. Formation of reddish violet colour indicates the presence of triterpenoids. A purple colour formed then changed to deep red after few minutes, indicates the presence of triterpenoids. Test for Proteins and Amino Acids i Ninhydrin test: 1.

Appearance of purple colour shows the presence of amino acids. Appearance of purple colour shows the presence of proteins. Test for Anthraquinones 5 ml of the extract solution was hydrolyzed with dil. H2SO4 and extracted with benzene. Rose pink colouration indicated the positive response for anthraquinones.
