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.

Synthesis, Characterizations and Photodegradation of Zn-doped Bismuth oxide Nanoparticles using Precipitation Method | Chapter 5 | Innovative Solutions: A Systematic Approach towards Sustainable Future

Aims: The aim of the study is to synthesize Zinc doped Bismuth oxide nanoparticles by simple precipitation method, their characteristics and to investigate the photocatalytic activity of these nanoparticles for Brilliant Green (BG) dye.

Study Design: Synthesis of Bi₂O₃ nanoparticles by precipitation method and photocatalysis of Brilliant green by using Bi₂O₃ nanoparticles.

Place and Duration of Study: Department of Physics, School of Applied Sciences, REVA University, Bangalore, between January 2024 to May 2024.

Methodology: The Zn/ Bi₂O₃nanoparticles were synthesized by simple precipitation technique using Bismuth nitrate as precursor. The synthesized Zn/ Bi₂O₃ nanoparticles were studied for structural, optical, and morphological properties using X-ray diffraction (XRD), ultraviolet-visible spectroscopy, scanning electron microscopy (SEM) techniques. Dye degradation studies by UV source.

Results: XRD patterns were well matched with the JCPDS card number 00-27-0050 with tetragonal structure with the crystallite size of 26.18 nm. The SEM analysis revealed the oxide particles to have spherical morphology. The band gap of Bi₂O₃ nanoparticles was calculated using Tauc’s plot and found to be 2.94 eV.

Conclusion: Zinc doped Bismuth oxide is a very good catalyst and can be used for photodegradation of a dye and helpful in commercial production of removal of such pollutants.
