摘要
目的研究锦灯笼和枸杞子对乳酸菌的促生作用,为微生态制剂的开发及中药合理使用提供理论依据。方法将不同浓度的锦灯笼和枸杞子水提液添加到乳酸菌的体外生长培养基中,37℃培养48h,活菌计数。结果 2%和5%的锦灯笼以及0.5%和1%的枸杞子对乳酸菌生长具有明显的促进作用(P<0.01),5%的锦灯笼促进乳酸菌生长的效果最好,菌数分别是对照组的1.6倍左右,但随着药物浓度的增加,两种药物促乳酸菌生长的作用显著减弱。结论一定浓度的锦灯笼和枸杞子水提液能够促进乳酸菌的生长。
Objective To study the growth-promoting effects of Physalis alkekengi L. var. franchetii （Mast.） Makino and Lycium barbarum L. on Lactobacillus and to provide a theoretical basis for the development of microecologics and proper use of traditional Chinese medicines. Methods Different concentrations of water extracts of P. alkekengi L. var. franchetii （Mast.） Makino and L. barbarum L. were added into the in vitro culture medium of Lactobacillus delbrueckii, and then viable count was performed after 48 h of culture at 37℃. Results The growth of L. delbrueckii was significantly promoted by 2 % and 5 % water extracts of P. alkekengi L. var. franchetii （Mast.） Makino and 0.5% and 1% of water extracts of L. barbarum L. （P 〈0.01） ; 5% water extract of P. alkekengi L. var. franchetii （Mast.） Makino had the best growth-promoting effect, and it led to an about 1.6-fold increase in the number of bacteria as compared with that in the control group. However, the growthpromoting effects of the two medicines decreased significantly as their concentrations increased. Conclusion The growth of Lactobacillus can be promoted by certain concentrations of water extracts of P. alkekengi L. var. franchetii （Mast.） Makino and L. barbarurn L.
