Antigiardial effect of Alga Ulva Lactuca by decreasing cysts

In this research the samples of alga Ulva lactuca were collected from Chahbahar in summer. Then the genus and species of the samples were determined microscopically and macroscopically. For long term storing, the algae were dried in shade and powdered to fine particles. Extraction were done with water and organic solvents. The antigiardial effect of Ulva lactuca assessed at 25C and 37c. In respect to findings, the extracts of alga Ulva lactuca had severe antigiardial effect. The chloroform extract were stronger that water ones, but with respect to the economical applicability the water form was more impotrant and after 24 hr all of the cyst were destroyed. For chemical analysis TLC, (UV-VIS), HPLC methods were used. In the TLC method, RFs in each extract were determined and alkaloids in some of them detected. From the GLC and HPLC method the relative activity of agents determined that were appropriate for themselves.
