Summary
The study shows that Ganoderma lucidum (GB) absorbs water without structural changes, forming hydroxyl bonds. This interaction is explained by its lipophilic nature and dehydration potential.
Area of Science:
- Materials Science
- Biochemistry
- Spectroscopy
Background:
- Ganoderma lucidum (GB) is a medicinal mushroom with potential applications.
- Understanding its interaction with water is crucial for its use and preservation.
- Previous studies have not fully elucidated the physical and chemical interactions between GB and water.
Purpose of the Study:
- To investigate the effect of varying water ratios on the Infrared (IR) spectrum of Ganoderma lucidum (GB).
- To elucidate the interaction mechanism between GB and water at a molecular level.
- To characterize the physical and chemical properties of GB concerning water absorption and stability.
Main Methods:
- Infrared (IR) spectroscopy was employed to analyze GB samples with different water content.
- Differential Scanning Calorimetry (DSC) was used to assess thermal properties related to water interaction.
- Liquid Chromatography-Mass Spectrometry (LC-MS) was utilized to further understand the chemical interactions.
Main Results:
- GB's IR spectrum showed changes in absorption strength at specific wavenumbers (3452, 1793, 1780, and 1630 cm⁻¹) with varying water content.
- Water molecules were found to be concealed within the GB's cage-like skeleton, forming hydroxyl bonds with GB's hydroxyl groups.
- GB's fundamental structure remained unchanged, adhering to standardized GB characteristics, despite water absorption.
- GB was confirmed to be lipophilic, insoluble in water, but readily absorbs environmental moisture.
- Dehydration of GB is possible under specific conditions.
Conclusions:
- GB exhibits significant water absorption capabilities due to its porous structure and hydroxyl groups.
- The interaction with water does not compromise the structural integrity or standardization of GB.
- GB's lipophilic nature influences its interaction with water, suggesting potential for controlled hydration and dehydration processes.

01:29IR and UV–Vis Spectroscopy of Aldehydes and Ketones
Infrared spectroscopy, also known as vibrational spectroscopy, is mainly used to determine the types of bonds and functional groups in molecules. In aldehydes and ketones, the carbonyl (C=O) bond shows an absorption around 1710 cm-1. The C=O bond vibration of an aldehyde occurs at lower frequencies than that of a ketone. In addition to the C=O absorption in an aldehyde, the aldehydic C–H bond also gives two peaks in the 2700–2800 cm-1 range. This absorption, coupled with the C=O stretching, is...
01:23IR Spectrum Peak Broadening: Hydrogen Bonding
The vibrational frequency of a bond is directly proportional to its bond strength. As a result, stronger bonds vibrate at higher frequencies, while weaker bonds vibrate at lower frequencies. The stretching vibration of the strong O–H bond in alcohols and phenols (very dilute solution or gas phase) appears as a sharp peak at 3600–3650 cm−1.
However, the extent of hydrogen bonding influences the observed stretching frequency and band broadening. Intermolecular or intramolecular hydrogen bonding...

01:03IR Frequency Region: Fingerprint Region
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the C=O, C=N, and C=C occur between 1600–1850 cm−1.

01:24IR Frequency Region: X–H Stretching
In IR spectroscopy, signals produced by the X−H bonds (such as C−H, O−H, or N−H) can be observed in the frequency range of 2700–4000 cm–1. The C−H stretching vibration forms sharp bands in the region 2850–3000 cm–1. The presence of the O−H stretching vibration leads to the forming of an absorption band in the frequency range 3650–3200 cm−1. At the same time, N−H stretching can be confirmed by absorption bands in the 3500–3100 cm−1 range. Even though both O−H and N−H bonds vibrate at a similar...
01:28IR and UV–Vis Spectroscopy of Carboxylic Acids
In IR spectroscopy of carboxylic acids, the C=O bond shows a characteristic band between 1710 and 1760 cm⁻¹, and the O–H bond exhibits a broad band between 2500 and 3300 cm⁻¹.
However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency, 1710 cm−1. The C=O bond of the...

01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given structure by adding the contributions...
