The results indicated that : jaj could selectively stimulate the reprduction of bifidobacteria in vivo and inhibit the growth of e. coli which is a main parasitic basterium in human intestinal tract ; moreover, jaj could apprarently improve intestinal tract function. in tested group, the mice excreted smoothly and the faecal particles of mice were big and wet, but in control group, the faecal particles of mice were small and dry. lt was suggested that inulin may be the important effective component in jaj which promoted the reprduction of bifidobacteria in vivo. at last, the effects of ja on the bile salt resis tance of bifidobacteria were studied. the test proved that : deoxycholic acid na - salt ( dca - na ) had intensely toxical action on blm and bbm ; adding glucose and fructose in media could decrease the lexical action on bbm. but inulin and jap had not apparent effect

基之後,進
一步以健康昆明系小鼠為實驗動物,研究了
菊芋在動物腸道內對雙歧桿菌的影響,動物實驗結果表明,
菊芋汁在體內對雙歧桿菌有選擇性促進生長作用,而腸道中主要條件致病菌?大腸桿菌的生長受到抑制;
菊芋中的
菊糖成分可能對
菊芋在體內選擇性地促進雙歧桿菌生長起了主要作用;此外,
菊芋還具有明顯的整腸作用,同對照組相比,飼喂
菊芋汁的小鼠排便順利,糞便顆粒大且濕潤。
