2 Aspergillus niger 9 mm 11 mm - 23 mm
3 Aspergillus pterus - 30 mm - 36 mm
4. Conclusions
The constituents contained in Chloroform exhibit sub-
stantial activity against Aspergillus flavus and Aspergil-
lus pterus. The results obtained confirm the therapeutic
potency of Origanum vulgare used in traditional medi-
cine. In addition, these results form a good basis for se-
lection of the plant for further phytochemical and phar-
macological investig ation.
