Dosage By Irtf Spectroscopy Of Meroditerpens With Hydroquinon Nucleus In Brown Alga Cystoseira Stricta

The objective of this work is the development of a new analytical method for the dosage of Meroditerpens in brown alga Cystoseira stricta. Meroditerpens are analyzed as hydroquinone by exploiting the specific area of the band 1512cm-1, characteristic of the C = C vibration of hydroquinone nucleus. The yield of the moderately polar meroditerpens with hydroquinon nucleus is 4.0 eg / g and that of polar meroditerpens is 2.8 eg / g.
