Antioxidant Activity from Cymodocea serrulata Seagrass Crude Extract

Introduction: Cymodocea can be found in clear water and in the high intertidal areas.The antioxidant study of the extract of C. serrulata shows the highest free radical scavenging property on ethanol extract. This may be due to the presence of high phenolic compounds. The study brings out the medicinal value of C. serrulata which can be used as a nutraceutical compound in various food and pharmaceutical industries.Antioxidants are defending your body cell from damage caused by free radicals when they accumulated may cause oxidative stress. The synthetic antioxidants are producing more side effects, while natural antioxidants play a major role in scavenging free radicals without side-effects.

Aim: To analyse the antioxidant activity from cymodocea serrulata sea grass from crude extract.

Materials and Methodology: The fresh leaves of Cymodocea serrulata were collected from parangipettai coastal area, Tamil Nadu. The seagrass are washed thoroughly with tap water then shade dried on table tissue paper for 2-3 weeks and turn into a fine power. And 10g of dried powdered seagrass samples were mixed with 100ml of methanol/Ethanol.

Using DPPH assay, to extract 0.1ml add equal volume of DPPH 0.1 ml . After 20 min, absorb at 517 nm. Ascorbic acid is used as a standard concentration and DPPH was calculated.

Results: The result concludes that Cymodocea serrulata showed good antioxidant activity. when concentration increases the percentage of the zone of inhibition is also increased, which shows that it shows a good antioxidant activity.

Conclusion: In this study antioxidant activity was checked by using Cymodocea serrulata. Using DPPH assay, it has concluded that it has strong antioxidant activity from crude extract. In the future it can be used for medication and further studies can be done by using individual components for various particles.
