Mass Spectrometry: Complex Analysis

Mass Spectrometry: Complex Analysis

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.
GC–MS is a powerful hyphenated method commonly used in forensics and environmental...

Background:

Ginseng (Panax species) is a vital medicinal herb, with ginsenosides as its primary bioactive compounds.
Mass spectrometry-based ginsenoside profiling is crucial for understanding ginseng's chemical diversity and applications.

Purpose of the Study:

To review the applications of ginsenoside profiling in ginseng research over three decades.
To highlight the impact of genetic variation on ginsenoside content and address limitations in previous studies.

Main Methods:

Comprehensive review of literature on ginsenoside profiling.
Presentation of new untargeted and targeted ginsenoside profiling data from different ginseng genotypes.
Analysis of genome-level genetic diversity and other study limitations.

Main Results:

Ginsenoside profiling has been instrumental in differentiating ginseng species, origins, and ages, and monitoring processing.
Genetic variation is a critical, often overlooked, factor influencing ginsenoside levels.
Previous studies often suffered from uncontrolled variables, insufficient metadata, and lack of causal validation.

Conclusions:

Integrating genetic variation and addressing methodological limitations can enhance the value of ginsenoside profiling.
Combining ginsenoside profiling with other omics techniques offers future research directions.
