Materials and Methods
A total of 44 dried fruit samples of
Moisture content determination
Known weight of the samples were dried in an oven at 100 0C for 1-21/2 h to determine their moisture content on the basis of weight loss using the following formula ( Essono et al. 2007):
MC = [(IW- FW)/ IW] ×100
Where, MC = Moisture Content; IW = Initial Weight; FW = Final Weight
Isolation and Identification of Fungi:
Fungi were isolated from different stored fruit samples of
Results and Discussion
The mycological examination of all the three types of fruit samples revealed that, 97.77% of the total samples were found to be contaminated with one or another fungal species.
A total of 12 different fungal species were isolated from all the three types of fruit samples of
Fungal species isolated from the stored herbal drugs are shown in the fig.1.
During the survey and collection of samples it was found that from the field these fruits are mostly transported without taking any care about the fruit damage and then these fruits are stored in open, unclean tin containers or in the market, thereby exposing them to microbial infection. Most of the identified fungal species like
The present pilot study on a small number of three types of herbal fruits therefore indicated that presence
