Summary
Direct analysis in real time-high resolution mass spectrometry (DART-HRMS) rapidly identifies plant species using chemical fingerprints. This high-throughput method bypasses lengthy sample preparation, enabling quick botanical identification.
Area of Science:
- Analytical Chemistry
- Plant Sciences
- Chemotaxonomy
Background:
- Traditional plant identification methods can be time-consuming and require extensive sample preparation.
- Accurate species identification is crucial for botanical research, quality control, and regulatory purposes.
- Developing rapid, high-throughput analytical techniques for botanical materials is an ongoing challenge.
Purpose of the Study:
- To demonstrate the utility of direct analysis in real time-high resolution mass spectrometry (DART-HRMS) for plant species identification.
- To showcase the ability of DART-HRMS to generate unique chemical fingerprints for botanical materials.
- To evaluate the efficiency and accuracy of DART-HRMS coupled with statistical analysis for rapid plant identification.
Main Methods:
- Direct analysis in real time-high resolution mass spectrometry (DART-HRMS) was employed for rapid chemical profiling of botanical samples.
- No sample extraction, derivatization, or pH adjustment was required, streamlining the analytical process.
- Multivariate statistical analysis was applied to the generated mass spectral data for pattern recognition and identification.
Main Results:
- DART-HRMS successfully produced distinct mass spectral profiles (chemical fingerprints) for different plant species.
- The technique allowed for rapid data acquisition without complex sample preparation, highlighting its high-throughput capability.
- Combined DART-HRMS and statistical analysis enabled accurate identification of plant materials at the species and varietal levels, as demonstrated with *Mitragyna speciosa* (Kratom) and *Datura* (Jimsonweed).
Conclusions:
- Direct analysis in real time-high resolution mass spectrometry is a powerful and efficient tool for rapid plant species identification.
- The DART-HRMS method bypasses limitations of conventional techniques, offering a faster and less resource-intensive approach.
- This technique, when integrated with statistical analysis, provides a robust platform for high-throughput botanical analysis and identification.

Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.Matrix-assisted laser desorption ionization (MALDI) is a commonly...

Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.

The resolution of a mass spectrometer depends on the efficiency of separating ions with different ion masses. The mass of an atom is approximated to the sum of the masses of protons and neutrons inside, considering the masses of protons and neutrons as equal. However, the masses of the proton (1.6726 × 10−24 g) and neutron (1.6749 × 10−24 g) are not truly equal. There is a minor error in the expression of atomic masses relative to the simplest atom of hydrogen. For...
