Summary
This research examined the genetic makeup and quality of Lingzhi mushrooms (Ganoderma lucidum) from different regions in China. The study found significant variations in quality and identified some incorrect strains being used in production. This has important implications for consumers and the medicinal mushroom industry.
Impacts on everyday life:
– Helps ensure consumers receive genuine and high-quality medicinal mushroom products
– Improves quality control standards for medicinal mushroom production
– Provides better understanding of how growing conditions affect mushroom properties
– Enables better identification of authentic Lingzhi products in the market
– Contributes to safer and more effective traditional medicine practices
Background
Ganoderma lucidum (Lingzhi) is an edible and medicinal fungus used in traditional Chinese medicine for over 2300 years. It contains bioactive compounds like polysaccharides, nucleosides, triterpenoids, peptides, sterols, proteins, and alkaloids. The quality of Lingzhi can vary based on strain differences, production region, growing conditions, cultivation techniques, and harvesting time.
Objective
To examine the genetic diversity of 22 strains of Lingzhi and analyze quality differences in 15 fruit bodies from different Chinese regions using genotyping by sequencing (GBS) and component analysis.
Results
Most strains were accurately identified except for a few inaccurate ones. All samples met Chinese Pharmacopoeia requirements for moisture, ash, water and alcohol soluble extractives, polysaccharides and triterpenoids. However, less than half met US Pharmacopoeia standards for polysaccharides and triterpenoids. The polysaccharides showed varying effects on spleen cell proliferation rates.
Conclusion
The study revealed genetic diversity among Lingzhi strains and identified some incorrect strains being used in production. Quality assessment showed varying levels of active compounds, with some samples not meeting US Pharmacopoeia standards. The activity of polysaccharides varied significantly, suggesting that both content and bioactivity should be considered in quality evaluation.
