Validation parameters of the main components of sea urchin extracts at λ 254 nm.

Standard Sample	Equation of Peak Area Versus Concentration	R2	LOD * (ng/mL)	LOQ ** (ng/mL)
1	y = 7.3003x − 0.1007	0.9992	48	159
3	y = 6.5882x − 0.2588	0.9990	40	134
11	y = 4.5986x − 0.4385	0.9984	72	240
16	y = 9.5797x − 0.2320	0.9991	22	72

* LOD: limit of detection; ** LOQ: limit of quantification.
