The Jellyfish having potential biological active compounds by tentacles. This bioactive compound was useful in biomedical industry. The extracts of
Chrysaora quinquecirrha exerted an immunostimulating effect of 40 to 25% magnitudes at lower concentrations and a suppressive effect of 33% at
higher concentration.
The fractionated extract exhibited immunostimulation ranging from 25 to 40% at concentrations up to 1000 μg.
These facts mean that jellyfish extracts had immunostimulation effect, and the active substance in jellyfish extract is secondary amides and polypeptides.
Thus the jelly fish extract is found to be useful tools for probing biological or pharmacological activity.
