Spectroscopic Methods for Analysing Herbal Medicine and their Roles in Healthcare |Chapter 1 | Pharmaceutical Science: New Insights and Developments Vol. 10

 

Background: Spectroscopic methods are very fundamental, convenient, cost-effective and available equipment settings in both industry and laboratory to analyse a range of products, including food, medicines, cosmetics and herbal products. Herbal drugs, that is, plant-derived products, have been used in the healthcare system from ancient times. There are different types of spectroscopic methods, among which ultraviolet and visible spectroscopy, infrared spectroscopy, atomic absorption spectroscopy, Mass spectroscopy, Fluorescence spectroscopy and Nuclear magnetic resonance spectroscopy are widely used for analysing herbal drugs.

 

Materials and Methods: PubMed, Research Gate, Google Scholar and other search engines, including Artificial intelligence tools, have been searched to find suitable literature to find relevant research works. The keywords “Spectroscopy”, “Herbal medicines”, “UV-VIS spectroscopy”, “Analysis”, “Infra-Red spectroscopy”, “Raman spectroscopy”, “Atomic absorption spectroscopy”, “Mass spectroscopy”, “Nuclear magnetic resonance spectroscopy”, “Analysis of herbs and phytoconstituents” etc. have been applied to find expected research articles and collect information on various aspects of spectroscopic methods for analysing herbal medicine and their roles in healthcare.

 

Results: After a thorough study of a lot of published articles, standard textbooks and related literature, we found some spectroscopic methods which are suitable for the analysis of herbal drugs. Some of these methods are - ultraviolet spectroscopy, infrared and Fourier Transform Infra-red spectroscopy, Raman spectroscopy, atomic absorption spectroscopy, fluorescence spectroscopy, Nuclear magnetic resonance spectroscopy and mass spectroscopy. Several tandem systems integrate spectroscopic and chromatographic techniques. Prominent examples include gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). These methods are highly suitable, specific, sensitive, and readily amenable to validation.

 

Conclusion: Spectroscopic methods provide a reliable and cost-effective approach for evaluating phytochemical potency and ensuring the quality of herbal preparations, making them essential tools in routine laboratory analysis.

Elaboration and Characterization of Phosphosilicates Apatites Containing Lanthanum| Chapter 1 | Recent Trends in Chemical and Material Sciences Vol.7

  In the temperature range of 1200–1400°C, two series of strontium–lanthanum apatites, Sr10-xLax(PO4)6-x(SiO4)xF2 and Sr10-xLax(PO4)6-x(SiO4)xO with 0 x 6, were produced by solid state reaction. The crystal structure and vibrational active modes of the produced materials were investigated using X-ray diffraction, NMR spectroscopy, and infrared and Raman studies.

Within a narrow spectrum of unsubstituted phosphate and silicate apatites, pure solid solutions were obtained. The radius of the corresponding substituted ions influenced the fluctuation of the lattice parameters, with a rise in a and a decrease in c.
The vibration modes of the PO4 and SiO4 groups were allocated to the bands of infrared and Raman spectra. When the results of the 29Si MAS NMR investigation were compared to those of the 31P, it was discovered that both species occupied the same crystallographic positions.

Substituent, Temperature and Solvent Effects on the Keto-Enol Equilibrium in β-Ketoamides: An NMR and Theoretical Study | Chapter 2 | Current Research and Development in Chemistry Vol. 4

 Using nuclear magnetic resonance spectroscopy (NMR), substituent, temperature and solvent effects on tautomeric equilibria have been investigated in several β-ketoamides. Keto-enol tautomerism is observed and in this series of β-ketoamides the equilibrium of amide-imidol is not detectable. In solution, these compounds exist primarily as ketoamide and Z-enolamide tautomers, both forming intramolecular hydrogen bonds. Considering the electronic and steric effects and tautomer stabilisation through internal hydrogen bonds, the relative stability of the individual tautomers and the subsequent equilibrium shifts are clarified. Theoretical calculations endorse those assumptions.

Experiments on the Isolation of Bulk Amount of Piperine as Active Pharmaceutical Ingredient (API) from Black Pepper and White Pepper (Piper nigrum L.) | Chapter 10 | Trends in Pharmaceutical Research and Development Vol.4

 

Piperine is a naturally occurring alkaloid which can be considered as major bioactive phytochemical
having broad spectrum of pharmacological activities. It is obtained from the most valuable
ethnomedicinal spices peppercorns i.e. black pepper and white pepper, which are the fruits of the
Asian vine Piper nigrum L. The present article reveals a simple and effective isolation method of bulk
piperine. The novelty of this investigation is to provide an idea for utilizing such natural method of
large scale commercial piperine production as API drug in spite of chemical synthesis. Piperine was
isolated in a pure crystal form and characterized by its melting point, X-Ray diffraction (XRD) studies
and spectral data, including two-dimensional nuclear magnetic resonance (2D-NMR) spectroscopy.
Chromatographic techniques like Thin Layer Chromatography (TLC) and High Performance Liquid
Chromatography (HPLC) were applied to determine the purity of the yielded piperine. Considering the
yield results of value and purity it is indicated that, such effective isolation method can be successfully
utilized for industrial large-scale production commercially. According to the result, it can be claimed
that, as a natural product the isolated piperine can also be utilized as API drug like other expensive
chemically synthesized piperine in different drug formulation.
