摘要
为了解黄芪对肠道内益生菌的促生作用,采用黄芪提取液对保加利亚乳酸杆菌、乳酸链球菌、三种混合菌(保加利亚乳酸杆菌、双歧杆菌和嗜热乳酸链球菌)进行体外实验,测定菌体在不同黄芪浓度的MRS液体培养基中的吸光度值(OD值)。结果表明,保加利亚乳酸杆菌、乳酸链球菌、三种混合菌(保加利亚乳酸杆菌,双歧杆菌和嗜热乳酸链球菌)的OD值随着添加黄芪浓度的增加而增大,到达8μg/mL以后,OD值基本不发生变化。一定浓度的黄芪提取液对乳酸菌的生长能起到促生作用。
For studing on promoting growth action of Radix Astragali on intestinal Probiotics, the extract of Rix Astragali was adopted to Lactobacillus Bulgaria, L.B. Lactic Streptococulls and three kinds of mixed Lactic bacterium （Lactobacillus Bulgaria, L.B. Lactic Streptococulls and S. thermophilus） and the absorbance （OD value） of bacterium in different concentration extract of Radix Astragali was measured. The result indicated that OD value of Lactobacillus Bulgaria, L. B. Lactic Streptococulls and three kind of mixed Lactic bacterium （Lactobacillus Bulgaria, L. B. Lactic Streptococulls and S. thermophilus） increased with the concentration of extract of Radix Astragali increased, and OD value did not change basically after 8μg/mL. The study showed that Radix Astraga- li had promoting growth action to Probiotics.
