Summary
A novel multi-column, multi-detector liquid chromatography system was developed for comprehensive analysis of traditional Chinese medicines. This advanced system successfully identified numerous compounds in Ganoderma species, aiding in understanding their chemical profiles.
Area of Science:
- Analytical Chemistry
- Pharmacognosy
- Natural Product Chemistry
Background:
- Traditional Chinese Medicines (TCMs) require advanced analytical methods for comprehensive chemical characterization.
- Understanding the diverse chemical constituents in TCMs is crucial for quality control and therapeutic efficacy.
Purpose of the Study:
- To develop and validate a sophisticated liquid chromatography system for analyzing global components in TCMs.
- To apply the developed system for the detailed chemical profiling of Ganoderma species.
Main Methods:
- A multi-column (size exclusion, hydrophilic interaction, reversed-phase) and multi-detector (diode array, evaporative light scattering, mass spectrometry) liquid chromatography system was designed.
- Column switching techniques were employed to enable the separation and detection of compounds with varying polarities.
- The system was applied to analyze Ganoderma lucidum and Ganoderma sinense.
Main Results:
- The system successfully analyzed macromolecular (polysaccharides), high-polarity (nucleosides, sugars), and low-polarity (triterpenes) compounds.
- One macromolecular peak was observed in both Ganoderma species analyzed.
- Nineteen components, including sugars, nucleosides, and triterpenes, were identified in Ganoderma lucidum, while four components were identified in Ganoderma sinense.

01:14Gas Chromatography–Mass Spectrometry (GC–MS)
Gas chromatography–mass spectrometry (GC–MS) is the combination of analytical techniques of gas chromatography and mass spectrometry in a single instrument for analyzing a mixture of compounds. The gas chromatograph separates the compounds in the mixture, and the mass spectrometer analyzes each compound separately to determine the molecular masses and molecular structures.
A gas chromatograph consists of a long, narrow capillary column with a polysiloxane coating on the inner wall. The coating...

01:15High-Performance Liquid Chromatography: Types of Detectors
The role of the detectors in High-Performance Liquid Chromatography (HPLC) is to analyze the solutes as they exit from the chromatographic column. The detector recognizes the solute's property and generates corresponding electrical signals, which are converted into a readable graph of the detector's response versus elution time called a chromatogram at the computer. There are several types of HPLC detectors, each with its own advantages and limitations, depending on the analyte properties and...
01:13Gas Chromatography: Overview of Detectors
Detectors in gas chromatography (GC) help identify and quantify the components of a mixture by translating chemical properties into measurable signals, which are displayed on a chromatogram. Detectors can be categorized into two main types: destructive and non-destructive.
A non-destructive detector allows a sample to be analyzed without altering or consuming it, meaning the sample can be collected after detection for further analysis. Examples include thermal conductivity detectors and...

00:57High-Performance Liquid Chromatography: Instrumentation
High-performance liquid chromatography, or HPLC, is an analytical technique that separates liquid samples under high pressures. An HPLC instrument consists of glass bottles for storing solvents called mobile phase reservoirs. HPLC-grade solvents are used to maintain high purity, and the dissolved gases are removed using a degasser, such as a vacuum pumping system or sparging with helium. The solvents are then pumped into the analytical column using a screw-driven syringe or reciprocating pumps.
01:13Gas Chromatography: Introduction
Gas chromatography (GC) is a technique for separating and analyzing volatile compounds in a sample. Its primary purpose is to identify and quantify components in complex mixtures, making it essential in fields such as environmental analysis, pharmaceuticals, and petrochemicals. GC is also called vapor-phase chromatography (VPC) or gas-liquid partition chromatography (GLPC).
In GC, a sample is vaporized and mixed with an inert carrier gas (the mobile phase), which transports it through a column.

01:11High-Performance Liquid Chromatography: Introduction
High-performance liquid chromatography(HPLC), formerly referred to as High-pressure liquid chromatography, is a powerful technique used to separate, identify, and quantify components in complex mixtures. The term "high pressure" refers to using high pressure to push the liquid mobile phase through the tightly packed columns.
In HPLC, two phases play a critical role in the separation process:
