Effects of Dioscorea batatas and Gastrodia rhizoma on Lipid Compositional Changes of Liver, Brain and Kidney in Rats

마분말과 천마분말이 흰쥐의 간, 뇌 및 신장의 지질성분 변화에 미치는 영향

The present study tested to recommend optimum level of Gastrodia rhizoma and effect on the compositional changes of the lipids in Sprague Bawley rats which were fed control diet adding 5, 10, 15% Dioscorea batatas powder and 5, 10, 15% Gastrodia rhizoma powder for 3 weeks, respectively The contents of moisture. ash, fat, protein and carbohydrate in dried Gastrodia rhizoma were 5.9, 2.7 2.1, 0.9 and 88.4%(w/w) respectively. Concentrations of total cholesterol and free cholesterol in liver were the lowest in the 10% Gastrodia rhizoma group. Concentrations of triglyceride and phospholipid in liver were lower in the 10 and 15% Gastrodia rhizoma groups than in the other groups. Concentrations of total cholesterol, free cholesterol, triglyceride and phospholipid in brain were significantly lower in the group 6, 7 compared to the other groups. Concentrations of triglyceride and phospholipid in kidney were slightly lower in the Gastrodia rhizoma groups than those in the Dioscorea batatas groups.
