We propose an efficiency analysis method to test whether Schisandra tea is beneficial to the health of internal organs, and, if so, to find which organ is mostly benefited. Firstly, for this, the color change in the right cheek region of face images before and after drinking Schisandra tea is analyzed using image processing techniques. Also, acoustic analysis experiments on both of the vocal cords vibration and the intensity value of acoustic signal are performed to investigate further Schisandra tea's effectiveness. The results of lung function smoothly by eating omijacha become. Vocal cords vibration and voice energy intensity of the right cheek region has changed a steady increase of the b values were observed.

This study was conducted to evaluate the influence of fertilization on characteristics of growth and accumulation of anthocyanin in fruit of Omija (Schisandra chinensis Baillon). Nitrogen supply mainly affected growth of fruit and the anthocyanin content in Omija respective of vegetative growth steps. The anthocyanin content in fruit was significantly low in high N supply and non-fertilization. The conjunctive supply of nitrogen and compost tea resulted in a higher anthocyanin content of fruit, total nitrogen content of leaf, and nitrate in soil. This result implies that nitrogen supply to Omija plant, affects the accumulation patterns of anthocyanin in different ways, e.g. it delays the quantitative biosynthesis at low nitrogen supply during fruit maturation or enhances anthocyanin degradation during the final maturation steps.

This study compared the content change of physiological active substances according to the extraction condition when we generally drink the extractive of Schisandra fruit with using water. Physiological active substances of the Schisandra fruit, schizandrin, gomisin A and gomisin N were analysed with HPLC. The results of extracting 1 dose of the Schisandra fruit tea, which is some as 1 g of Schisandra fruit, in 100 mL of water by differing the extraction type, extraction temperature and extraction time were of the followings. The total content of schizandrin, gomisin A and gomisin N of powder type in $26^{\circ}C$ leaching was the highest (p < 0.05) as the leaching content of 24 hours (5.54 mg/g) showed difference with different times and the contents of raw type Schisandra fruit were less than 0.1 mg/g in all of extraction time. The contents of powder type Schisandra fruit in $60^{\circ}C$ heating extraction was over 4.50 mg/g except for the 5 minute (2.94 mg/g), and the contents of raw Schisandra fruit were less than 0.3 mg/g. In case of $100^{\circ}C$ heating extraction, the contents of powder type Schisandra fruit showed over 5.10 mg/g in every time zone, and the raw type Schisandra fruit was less than 1.0 mg/g.

This study was aimed to investigate the contents of flavonoids and the biological activity of fermented beverage of medical plants, DeulBit (DB). 50 g of Cassia semen (Cassia tora L.), 50 g of Omija (Schisandra chinensis Baillon.), 50 g of Gugija (Lycium chinense Mill), 50g of Menthae herba, 75 g of Chrysanthemum indicum Linne, 25 g of Dioscorea batatas, 5 g of Lindera obtusiloba Blume, 150 g of Polygonatum odoratum, 25 g of Glycyrrhiza uralensis, 25 g of Acanthopanacis cortex, 100 g of green tea (Camellia sinensis), and 100 g of Laminaria japonica was fermented with sucrose ($50.0{\sim}60.0^{\circ}Brix$.) and 0.5% of deep sea water in 10 L of distilled water for six months at room temperature. Total flavonoids contents of DB was calculated to $3.4{\pm}0.5\;{\mu}g/g$ and antioxidative activity of DB was measured by using DPPH radical scavenging and SOD-like activity. DPPH radical scavenging and SOD-like activity of DB was 96% and 29% at 100% of DB, respectively. In addition, DB indicated about 88% and 66% of the xanthine oxidase and angiotensin converting enzyme inhibitory activities at 1% and 10% of DB, respectively and showed fibrinolytic activity. Nitric oxide (NO) synthesis was increased to 15 times by addition of DB. In addition, NO productions of the macrophages RAW264.7 cells stimulated with lipopolysaccharide (LPS) were reduced to 40.4% by addition of DB. These results suggested that DB is significant role for antioxidative and fibrinolytic activity, and have the strong xanthine oxidase and angiotensin converting enzyme inhibitory activities.
