Figure Lengend Snippet: Absorption spectra in the UV–Vis region (200–700 nm) of the Tetraselmis tetrahele extracts with (A) UAE and (B) maceration. The peak at 337 nm suggests UV-absorbing compound, bands at 440 nm and 664 nm correspond to chlorophyll a , and the peak at 466 nm is associated with carotenoids. brief title: Absorption spectra of Tetraselmis tetrahele extracts.

Article Snippet: Total carotenoids and chlorophyll contents of microalgal extract (1 mg/mL) were determined according to Lichtenthaler and Buschmann at 470, 648, and 664 nm using a UV–Vis spectrophotometer (V-770ST, Jasco).
