Some xylem fibers developed an additional secondary wall layer by the last sampling date that was only slightly lignified, as determined by visual appraisal of phloroglucinol staining.
Steinberg (1988) demonstrated the grazing-deterrent effects of algal phlorotannins by incorporating them into agar and using assays similar to ours, and pointed out that, unlike low molecular mass compounds such as phloroglucinol, high molecular mass phlorotannins remained in agar quite well and could be tested in this manner.

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.
This study is the first to investigate the anticancer effects of the new phloroglucinol derivative (2,4-bis(4-fluorophenylacetyl)phloroglucinol; BFP).
