  1. Unless otherwise indicated, all glycosides and sulfates are attached at the flavonol 3-hydroxy group. Flavonol derivatives are listed, from left to right, in order of their elution from a reversed phase HPLC column. The number of "x" marks indicates the relative peak size, with xxx being the most prominent, xx less than about 50% of xxx or one of two or more peaks of similar size, and x significantly smaller, but present.
  2. 1Abbreviations: Ell, ellagic acid; Que, quercetin; Kae, kaempferol; Irh, isorhamnetin; Rhm, rhamnetin; Rhz, rhamnazin; Kad, kaempferide; Tam, tamarixetin; Glr, glucuronide; Rha, rhamnoside; SO3, sulfate ester.
  3. 2Not 3-O-sulfate.
  4. 3observed after hydrolysis by HCl.
  5. 4T. pentandra = T. ramosissima. Both of these were very old (~100 years) herbarium specimens, in which some quercetin sulfate may have hydrolyzed to quercetin.
  6. 5Two different samples of the same object. 10050–1 was obtained about two years earlier than 10050–2.
