ABSTRACT
Objective: To study the biotransformation of Poria cocos by Ganoderma lucidum and the changes of total polysaccharide and total triterpenes contents of the biotransformation products. Method: The experiment uses the microwave method to extract and sulfuric acid-phenol method to measure total polysaccharide content. And the ultrasonic wave method was used to extract total triterpenes and the content was measured by vanillin-perchloric method. Result: After treatment by G. lucidum, the total polysaccharide and triterpenes content of the biotransformation products were significantly higher than the non-conversed P. cocos (P<0.01), showing that the original performance of P. cocos was changed by way of biotransformation of G. lucidum; P. cocos had a promotion effect on the growth of G. lucidum. Conclusion: Biotransformation of P. cocos for Increasing the total polysaccharide and triterpenes contents by using G. lucidum has advantages of simple, low cost and so on. This method has a certain application value in modernization of Chinese traditional medicine.
ABSTRACT
This review summarizes the present situation of research, development and application of the Chinese herbal feed additives and its prospect. It can provide scientific references for researchers to carry out in-depth study. Chinese herbal feed additives will hopefully solve problems such as antibiotic residues, environmental pollu-tion, low productivity which hinders the development of livestock and provides strong support for developing green husbandry, meeting the food safety demand, closing the gap of livestock between the developed countries and Chi-na, increasing competitiveness of Chinese animal products in world markets. The development of Chinese herbal feed additives have very important economic and social benefits.
