Mycobiota of Commercially Available Triphala Powder: A Well Known Dietary Supplement of Indian System of Medicine

摘要

Sixty samples, categorized on the basis of manufacturers, were analyzed during the study. A total of 16 fungal species, belonging to 7 different genera, were isolated from the collected samples.Aspergilluswas recorded as the most dominant genus with 9 species, namely,A. niger,A. carbonarius,A. luchuensis,A. fumigatus,A. flavus,A. nidulans,A. terreus,A. ochraceous, andA. wentii.A. nigerwas the most predominant species with frequency of occurrence of 63.33%. A large variation in fungal load and diversity was observed among the samples of different manufacturing categories. The percent moisture content and pH of samples were directly related to the extent of contamination. Samples with low pH and high moisture content were more contaminated. The higher incidence ofA. niger(74.36%) was observed among the triphala powder of all manufacturing categories. Detection of ochratoxin producing fungi in triphala powder may pose a serious risk of ochratoxin production. Thus, there is an urgent need to enforce quality standards and regulation to minimize the fungal contamination to the globally expectable limit.
