Screening of anti-inflammatory activity of seaweed samples against COX-1 and COX-2.

Sample	IC50 Value (µg/mL)		Selectivity Index, SI
	COX-1	COX-2
C.L.	48.96	42.74	1.06
M.L.	46.35	40.06	0.88
C.F.	47.41	42.27	1.58
M.F.	44.59	40.01	0.83
R.D.	49.64	45.19	1.07

Seaweed samples used were crude laminarin (C.L.), MWCO 10 kDa laminarin fraction (M.L.), crude fucoidan (C.F.), MWCO 10 kDa fucoidan fraction (M.F.), and reference drug (diclofenac sodium) as R.D.
