Optimization of Phenolic Compounds Extraction from Flax Shives and Their Effect on Human Fibroblasts

Figure 1

An influence of time of hydrolysis with sodium hydroxide and its concentration on phenolics content in flax shives extract. After the hydrolysis, each sample was acidified to pH = 3 and underwent three-time extraction with ethyl acetate using 100% solvent-to-solid material ratio.
