Raw materials of six medicinal plant species viz. Terminalia arjuna (Roxb. ex DC), Acorus calamus (L.), Rauvolfia serpentina (L.), Holarrhena antidysenterica (Roth.), Withania somnifera (L.) and Boerhaavia diffusa (L.) procured from herbal drug market were subjected to their mould profile. During mycoflora analysis, 906 fungal isolates were recorded from the raw materials. The least number of fungal isolates (96) were detected from T. arjuna while highest (217) from B. diffusa. The genus Aspergillus was found to be most dominant encountered in all the samples, followed by Cladosporium herbarum, Penicillium italicum and Trichoderma viride. The highest percent relative density was recorded in case of Aspergillus flavus (37.19) followed by A. niger (23.84) and C. herbarum (11.81) while the lowest was found in case of A. nidulans (0.55). Some of the A. flavus isolates were toxigenic secreting aflatoxin B1. Highest content of aflatoxin B1 (272.46 µg/kg) was recorded by A. flavus isolated from B. diffusa while least aflatoxin B1 production (194.62 µg/kg) from H. antidysenterica. The survey reveals that the contamination of herbal drugs with storage fungi and mycotoxin is alarming and appropriate quality control measures should be taken urgently.
