Abstract

Hyaluronidase degrades hyaluronic acid, the principal component of the extracellular matrix. Inhibition of this enzyme is thus expected to hinder skin aging. Brown alga Padina pavonica activity toward hyaluronidase was evaluated using capillary electrophoresis (CE)-based enzymatic assays. This green technique allows evaluation of the biological activity of the natural material in an economic manner. Pressurized liquid extraction (PLE), microwave assisted extraction (MAE), supercritical fluid extraction and electroporation extraction techniques were used. Extraction conditions were optimized to obtain cosmetically acceptable Padina pavonica extracts with the best inhibition activity. CE-based assays were conducted using only a few nanoliters of reactants, a capillary of 60cm total length and of 50μm internal diameter, +20kV voltage for separation in 50mM ammonium acetate buffer (pH 9.0) and 200nm wavelength for detection. The reaction mixture was incubated for 1h and CE analysis time was about 11min. A novel online CE-assay using transverse diffusion of laminar flow profiles for in-capillary reactant mixing allowed efficient monitoring of hyaluronidase kinetics with K m and V max equal to 0.46±0.04mgmL-1 and 137.1±0.3nMs-1 (r 2=0.99; n=3), respectively. These values compared well with literature, which validates the assay. Water extracts obtained by PLE (60°C; 2 cycles) and MAE (60°C; 1000W; 2min) presented the highest anti-hyaluronidase activity. The half maximal effective concentration (IC 50) of water PLE extract was 0.04±0.01mgmL-1 (r 2=0.99; n=3). This value is comparable to the one obtained for Einsenia bicyclis phlorotannin fractions (IC 50=0.03mgmL-1), which makes Padina pavonica bioactivity very promising.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
