To investigate the protective effect of omija(Schizandra chinensis Baillon) tea extracts against the aluminum toxicity, Sprague-Dawley rats($100{\pm}10\;g$) were divided into 6 groups consisting of a control group, a 3% Schizandra chinensis Baillon tea plus extract group, a 1,000 and 2,000 ppm aluminum group, and a 1,000 and 2,000 ppm aluminum plus 3% Schizandra chinensis Baillon tea plus extract group. The rats administered aluminum were given 1,000 and 2,000 ppm of $Al_2(SO_4)_3$ dissolved in distilled water. The aluminum content in tissues from rats administered aluminum was lower than in the tissues of rats of administered aluminum plus 3% Schizandra chinensis Baillon tea in the water extract. Aspartate aminotransferase (AST) and alanine aminotransferase(ALT) levels were increased in the aluminum group and lower in the group receiving a 3% extract of Schizandra chinensis Baillon tea. Lactate dehydrogenase(LDHase) was lower in the group receiving a 3% extract of Schizandra chinensis Baillon tea plus aluminum than in the aluminum group. Cholinesterase(ChEase) was higher in the 3% Schizandra chinensis Baillon tea-aluminum group than in the aluminum group. Plasma levels of renin were increased in the aluminum group, compared to the group receiving 3% Schizandra chinensis Baillon tea plus aluminum. Plasma levels of aldosterone were increased in the aluminum group compared with the 3% Schizandra chinensis Baillon tea plus aluminum group. These results suggest that the group receiving Schizandra chinensis Baillon tea in water extract had a lowered level of aluminum accumulation, and it is believed that the Schizandra chinensis Baillon tea plus water had some protective effects against aluminum toxicity when administered in rats, but the mechanism of these effects remains obscure.

This study was conducted to investigate the characteristics of sponge cake quality added with different levels of Schizandra chinensis powder. Schizandra chinensis sponge cake was prepared with different levels of Schizandra chinensis (0, 5, 15, 20%). The proximate composition contents of Schizandra chinensis powder were analyzed as composed of 8.732% moisture, 10.25 crude protein, 8.63 crude lipid, and 1.98 crude ash. Results show that the baking loss rate was decreased with levels of Schizandra chinensis powder added, and the height was decreased as the Schizandra chinensis powder increased. As added ratio of Schizandra chinensis powder increased, L and b values were decreased. In addition, the texture properties result showed that the hardness and cohesiveness of sponge cake increased as the Schizandra chinensis powder added, while springiness decreased. Last, the sensory evaluation showed that the group of 5% Schizandra chinensis powder had the highest preference scores. Therefore, Sponge cake added with 5% Schizandra chinensis powder add gave the better taste and quality to sponge cakes in this study.

The purpose of this study was to investigate the effect of Schizandra chinensis extract on the serum and hepatic lipids inhyperlipidemic rats fed with high-fat diet. The Schizandra chinensis extract decreased significantly in total serum cholesterol, serum triacylglycerol and heptic triacylglycerol but not in the total hepatic cholesterol. The Schizandra chinensis extract also decreased in very low density lipoprotein increased by the highfat diet without affecting high density lipoprotein cholesterol. These results suggest that Schizandra chinensis extract may be benificial for the regulation of hyperlipidemia.

The objectives of this study were to investigate the antioxidant activity of Schizandra chinensis seed oil and its active ingredients. Schizandra chinensis seed oil content extracted with hexane was 36.06%. Schizandra chinensis seed oil extracted with hexane was purified during 20 min at $85^{\circ}C$ with phosphoric acid 0.15% for degumming and 20 min at $80^{\circ}C$ with 3 M NaOH 1% for deaciding. The purified oil consisted of unsaturated fatty acid (88.7%), fatty acid (9.97%), and so on. The major unsaturated fatty acids of purified oil were linoleic acid (71.1%) followed by oleic acid (15.7%), while the main saturated fatty acid was palmitic acid (6.56%). The purified oil was found that contents of phenolic compounds, vitamin A, and E were 1.45 g/100 g, 1494.86 RE/100 g, and 0.58 mg ${\alpha}$-TE/100 g, respectively. Schizandra chinensis seed oil exhibited strong antioxidant activity (91.7%) as compared to grape seed oil and canola seed oil with 87.4% and 85.1% in the DPPH assays. Present results suggest that Schizandra chinensis seed oil could be potentially used as bioactive source for health and preventing numerous diseases.

The anticancer activity of Schizandra chinensis Baillon was investigated for the development of functional food resources. The antiproliferative activity of hot water extracts of Schizandra chinensis Baillon in human colon cancer cell line (HT-29) were identified using cell viability, morphology study, cell cycle and RT-PCR analyses. HT-29 cells were cultured in several concentrations (0, 1.0, 2.0, 4.0 mg/mL) of water extracts of Schizandra chinensis Baillon. In our study, colon cancer cell growth could be inhibited by hot water extracts of Schizandra chinensis Baillon in a dose-dependent manners. It was associated with morphological changes and apoptotic cell death with cell shrinking, chromatin condensation, apoptotic bodies and cell cycle analysis. These results suggest that Schizandra chinensis Baillon may inhibit the growth of human colon cancer cells by various apoptosis-aiding activities as well as apoptosis itself.
