Abstract

|
|
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.
