Development of a Pressurized Green Liquid Extraction Procedure to Recover Antioxidant Bioactive Compounds from Strawberry Tree Fruit (Arbutus unedo L.)

Forget the strawberries—this tree's fruit hides a treasure trove of antioxidants, and scientists just found a greener way to unlock it.

The strawberry tree fruit (Arbutus unedo L.) is more than just a colorful berry—it's a natural pharmacy packed with bioactive compounds. But extracting these valuable molecules often involves harsh solvents and energy-intensive methods. Now, researchers have developed a greener alternative using pressurized liquid extraction (PLE), which uses high pressure and temperature to pull out the good stuff efficiently.

Key Points

• Green PLE method maximizes antioxidant recovery from strawberry tree fruit.
• Optimal conditions: 120°C, 10 min, 2 cycles with 96% ethanol.
• Temperature boosts most bioactives, but total phenolics and DPPH differ.
