The manuscript, entitled “Green extraction approach for green microalga Tetraselmis tetrahele: Enhanced phenolic yield and bioactivity via ultrasound-assisted extraction”, demonstrates that ultrasound-assisted extraction (UAE) is a green and scalable method for maximizing the phenolic yield. Different UAE parameters, including solvent composition, temperature, solid-to-solvent ratio, and extraction time, were optimized for the extraction of phenolic compounds from Tetraselmis tetrahele.

The findings support the potential application of marine microalga Tetraselmis tetrahele in the development of high-value products across pharmaceutical, cosmetic, and functional food industries. The LC-QTOF-MS profiling of the Tetraselmis tetrahele extract revealed a diverse metabolic profile, including amino-fatty acids, lipids, terpenoids, apocarotenoids, and xanthophyll derivatives. This metabolite diversity highlights the capacity of Tetraselmis tetrahele extract obtained via UAE as a sustainable and valuable source of bioactive compounds for various applications.
