Abstract

We extracted pine-needles using ethanol as solvent, and we obtained the refined oil component from pine-needles extract. Also we tested the tyrosinase activated inhibition effect with melanin experiment and analysed with ICP/OES and UV/VIS. Accordingly we obtained the next conclusion from the result of this experiment. From the first result of this experiment, we could know that the degree of recovery of refined oil component from pine-needles extract appeared in about 8.0%. From the second result of this experiment, we could know that the tyrosinase activated inhibition rate increased more and more in case of increasing concentration of pine-needles, green-tea, vitamine-C. Also we could know that vitarnine-C influences to tyrosinase activated inhibition contained in pine-needles. From the third result of this experiment, we could know that inorganic materials of Ca, Mg, V, Mn, etc contained in pine-needles detected with ICP/OES analysis, and the absorbance of pine-needles extract appeared very high in UV/VIS analysis.
