The pine needles can be used for four seasons in normal living and it can be taken friendly everywhere as it is distributed over 50% in Korea. The pine needles consist of vitamins, protein, minerals, essential oil and enzyme related to antimicrobial activity. It has effect like high blood pressure, neuralgia and hanged over by terpene, glucokinin, rutin, apigenic acid and tannin. Also the extract of them can be used for dyeing of fabrics. However, the extract components and effects of them are not well known yet. Therefore, the purpose of this study was to investigate the volatile components of the pine needles extract and functionality. The pine needles extract was dyed into various fabrics(nylon, silk, wool and soybean) and mordanted with Al, Cu, Cr, Fe and Sn. The extracted aroma compounds were compared by gas chromatography-mass spectrometry. The major volatile compounds of pine needles verified by using SPME were alpha-pinene, beta-pinene, beta-phellandrene, caryophyllene, ethanon, benzen. A total of 15 compounds were identified by using the SPME fibers. In the UV-visible spectra, the maximum absorption of wavelength of the pine needles ethanol extract appeared at 460, 630nm for chlorophyll component and at 237, 281nm for tannin component with the pine needles distilled water extract. Most of sample showed high antibacterial effect in none mordant but wool fabric showed high antibacterial effect in mordants. The result of UV block test showed a superior ability of blocking ultraviolet ray infiltration in all sample.
The pine needles has been used as medicines and it is using as dyeing as well as food. It is distributed through 50% in Korean forest. The pine needles is related to antimicrobial activity, however, dyeing properties of the extract components and effects of them are not well known yet. To examine dyeing properties of the pine needles extract, various fabrics(nylon, silk, wool, and soybean) were dyed under different dyeing conditions, and mordanted with one of five mordants(Al, Sn, Fe, Cr, and Cu). Dye uptake, Colors and Colorfastness of the dyed fabrics were measured. By the K/S values, dye uptake of all the dyed fabrics enhanced as increasing dyeing temperature and dyeing time. The highest K/S values were obtained from the protein fiber(wool and silk) fabrics dyed with water extract at 100℃, and with ethanol extract at 90℃ for 80 minutes. Colors of the dyed fabrics showed variety of yellow, brown and green colors. Colors changed by using Cu, Fe and Cr mordants: Cr-mordanted fabrics into light green, Fe-mordanted fabrics into reddish brown, and Cu-mordanted fabrics into deep green in ethanol extraction. Dry-cleaning fastness of the dyed fabrics presented good to excellent except wool fabrics dyed with ethanol extract. Washing fastness of the dyed nylon and soybean fabrics were good to excellent but wool and silk fabrics showed average grades. Most dyed fabrics were poor to light fastness.
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.
We have extracted the natural pine-needles to use ethanol in solvent, and could obtain the refined oil component from pine-needles extract. We have tested the antimicrobial effect from microbe experiment and analyzed with ICP/OES, GC/MS. we could obtain the next conclusion from the result of this experiment. In the first result of this experiment we could know that in case of increasing concentration of pine-needles, the number of microbe decreased more and more. Also we could know that the refined oil component of pine-needles appeared the sterilization effect of S-aureus and E-coli after 96hrs and 120hrs. So we could know that the refined oil component of appeared effect to microbe. In the second result of this experiment we could know that inorganic materials of Ca, Mg, V, Mn etcs from pine-needles detected to ICP/OES analysis and the aromatic compounds from refined oil component of pine-needles was certificated to GC/MS analysis.
