Researchers developed an efficient ultrasonic extraction method to obtain beneficial compounds from the lion’s mane mushroom (Hericium erinaceus), particularly a substance called erinacine A and antioxidants. The optimized process uses 80% ethanol and takes 45 minutes, producing extracts rich in antioxidants that can protect cells from damage. These extracts showed promise in protecting brain cells and could potentially help prevent or treat neurodegenerative diseases like Alzheimer’s disease.

Ultrasound-Assisted Determination of Selenium in Organic Rice Using Deep Eutectic Solvents Coupled with Inductively Coupled Plasma Mass Spectrometry

This study developed environmentally friendly solvents called deep eutectic solvents (DESs) to detect selenium in rice without using toxic chemicals. Researchers optimized four different DES formulations and used ultrasonic waves to extract selenium from rice samples. The new green chemistry approach achieved comparable or better results than traditional harsh acid digestion methods while being safer for the environment.
