Lindenane sesquiterpenoid dimers from Chloranthus holostegius with anti-neuroinflammatory activities in BV-2 microglia.

Scientists discovered fifteen previously unknown compounds, called chloranholides F-T, in the Chloranthus holostegius plant. These compounds show promising anti-inflammatory effects, inhibiting the production of the inflammatory mediator NO. Two specific compounds also suppressed the activity of iNOS and COX-2 enzymes.

Strawberry tree fruits (Arbutus unedo L.): Bioactive composition, cellular antioxidant activity, and 3D printing of functional foods.

Arbutus unedo fruits can be used to make functional foods with 3D printing, as they have biological activity and can protect DNA and act as an antimicrobial agent. The printing process affects the bioactive compounds, but the final products are still rich in polyphenols. Thus, A. unedo can be a sustainable resource for innovative functional foods.
