Researchers developed a new method to extract and purify erinacine A, a beneficial compound from lion’s mane mushrooms, using an advanced separation technique called high-speed countercurrent chromatography. They tested 15 different mushroom strains and found that a wild strain called HeG produced significantly more erinacine A than commercially cultivated varieties. Erinacine A shows promise for protecting brain health and potentially helping with diseases like Alzheimer’s and Parkinson’s. This discovery could help make erinacine A supplements more accessible and affordable for consumers.
