Abstract: Contamination of herbal drugs by microbes is a very common phenomenon as many reports are available, but what alteration occurs on secondary metabolites of plants due to these has very few records. In the present study, it has been established that the concentration of glycyrrhizin (active constituent) decreases by microbial contamination. The contamination of ten fungal species, viz. Aspergillus niger Tiegh., A. flavus Link, A. fumigates Fresentius, A. sydowii Thom & Church, Penicillium chrysogenum Thom, P. purpurogenum Stoll, Alternaria alternate (Fr.) Keissl., Cladosporium sphaerospermum Penz., Absidia corymbifera Sacc. & Trott., Rhizopus oryzae Went & Prins. Geerl. and three bacteria, viz. Escherichia coli (Migula) Castell. & Chalm., Pseudomonas aeruginosa (Schroeter) Migula and Salmonella Lignieres has been perceived in the samples of liquorice. Besides, a correlation between moisture, sugar, starch and microbial load has also been established. It was found that the sample having maximum moisture percentage had heavy microbial load. On the contrary, sugar and starch percentage were minimum in the same sample.
