  • 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.

  • Berberis koreana Palibin belonging to Berberidaceae family, a common herb in Korea, has been contained some quantity of Berberine analogue and other ingredients. Authors therefore paid attention to its pharmacological actions and examined the effects on sleep duration and rectal temperature in mouse with crystal (A) from Berberis koreana Palibin in Korean native plans. The experiment searching for the effect on sleep duration was performed with pretreatment of Berberis Koreana Palibin crystal (A) 30 min before the administration of 25 % ethanol, and its crystal were also administered intraperitoneally with the intention to examine the effect on rectal temperature in mouse. The results of the experiment were as follows; 1. Crystal (A) from Berberis koreana Palibin was made by extraction with ethanol and HCI. 2. Crystal (A) enhanced the hypnotic activity of alcohol in concentratins of 0.1 mg/10g or 0.15 mg/10g. 3. Rectal temperatures in mice were significantly reduced with administration of crystal (A) in concentrations of 0.1 mg/10g or 0.15 mg/10g. 4. The maximal reduction of rectal temperature and potentiation of the hypnotic activity were observed at 30 min after its administration. From the above results, it is clear that crystal (A) from Berberis koreana Palibin exerts the potentiation of hypnotic action of alcohol and reduction of rectal temperature in normal mouse. Its pharmacological effects are probably derived from the action upon the central nervous system.
