Variation of voltage with changes in concentration of the phenols was investigated for resorcinol, catechol, hydroquinoe and phloroglucinol, whereas, phenol (hydoxybenzene) was used as reference.

Earlier phytochemical explorations of members of this genus resulted in the identification of C-methyl flavonoids, triterpenoids, and phloroglucinol derivatives [3-6].
One unique group of polyphenols present in brown algae is phlorotannins (PT), which are polymers composed exclusively of phloroglucinol (Ragan and Glombitza, 1986; Arnold and Targett, 1998).

To each 30 [micro]l plasma, 3 ml of phloroglucinol (sigma) color reagent was added, then placed in boiling water for 4 min, then cooled in ice water, the absorption of each sample was read on a UV/Vis spectrometer (Perkin Elmer) set at 554 nm.
Two delphinidin degradation products of relatively low molecular weight were identified in phenol red-free tissue culture medium (pH 7.4, temperature 37[degrees]C) after 30 min incubation, using LC-MS/MS: gallic acid (GA; peak 1) and phloroglucinol aldehyde (peak 3) (Figure 3).
This study is the first to investigate the anticancer effects of the new phloroglucinol derivative (2,4-bis(4-fluorophenylacetyl)phloroglucinol; BFP).
Gallic acid, phloroglucinol, resorcinol and catechin were identified at different hours of incubation.
