Preliminary Studies on Its Glycyrrhizinic Acid Metabolites of Endophytic Bacteria from Glycyrrhiza inflata Bat. of Xinjiang
新疆胀果甘草内生细菌枯草芽胞杆菌产甘草酸类代谢产物的初步研究

Total 149 strains of endophytic bacteria were isolated from different healthy organisms of Glycyrrhiza inflata Bat. from Xinjiang. The fermented liquids of these strains were screened by TLC and analysed by HPLC, and the glycyrrhizinic acid monoammonium salt was taken as standard control at the same time. Only one endophtytic bacterial stain of Bacillus subtilis could produce Glycyrrhizinic acid monoammonium salt analogue.
