오미자 인제수집종의 과실부위별 schizandrin과 기름함량은 종자에서 가장 높았는데 각각 1.01%와 27.6%로 나타났다. 국내 수집종 오미자 55계통에 대한 성분분석 결과, 과실에 함유된 schizandrin의 함량은 평균 0.84%이었고, 종자에 함유된 기름함량은 평균 27.9%이었으며 지방산조성은 palmitic acid 3.6%, stearic acid 0.6%, oleic acid 19.7%, linoleic acid 73.1%, linolenic acid 3.0%로 불포화지방산조성이 95.8%로 높게 나타났다. 인제수집종 종자에서 용매추출한 기름은 4.29%의 schizandrin을 함유하여 오미자의 schizandrin은 종자기름에 대부분 함유되었다. 분쇄하지 않은 종자와 과실을 끓는 물로 추출하였을 경우 schizandrin수율은 각각 23.8%와 17.3%로 낮게 나타났다. 그리고 4개월 동안 물에 침지된 종자내 schizandrin과 기름성분은 상온 저장된 종자와 비슷한 함량인 1.18%와 25.2%를 나타내, 오미자 음료제조 후 부산물인 종자는 기름이나 지용성 약리성분을 추출할 수 있는 원료로 이용될 가능성이 있었다.
Histochemical distribution and varietal variation of schizandrin and oil compounds, and the changes of their extraction yield were investigated in fruits of collected Schizandra chinensis including Inje cultivar. In histochemical analysis on the distribution of schizandrin and oil in fruits of Inje cultivar, higher concentrations of them were found in the seed (1.01% and 27.6%, respectively) than in the epicarp and mesocarp of the whole fruit. Average contents of schizandrin in fruits and oil in seeds of collected lines were 0.84% and 27.9%, respectively. The mean composition of fatty acids in seeds oil was 3.6% of palmitic acid, 0.6% of stearic acid, 19.7% of oleic acid, 73.0% of linoleic acid, and 3.1% of linolenic acid, showing high composition(95.8%) of total unsaturated fatty acid. Oil extracted from seeds of Inje cultivar contained 4.29% of schizandrin, indicating that seed oil contained much schizandrin, a bioactive lipid-soluble compound. Compared with 80% methanol extraction in fruits and seeds, yields of schizandrin and oil were lower showing 23.8% and 17.3%, respectively in boiling water extraction of the fruits and seeds without grinding. The seeds soaked with water during four months contained 1.18% of schizandrin and 25.2% of oil, whose contents were similar to those of the seeds stored at room temperature. These results demonstrated that the seed in the whole fruit could be utilized as a source to extract its functional oil and bioactive lipid-soluble compounds like schizandrin, especially after using Schizandra fruits for the beverage manufacture.
