// Definition
Water-soluble pigmented compounds, including flavonoid glycosides and the newly identified flavo-alkaloids, that dissolve into the water phase during ice water hash extraction, producing the characteristic colored water discarded after washing.
// From the Episode
Dr. Scialdone explained that the sugar moieties bonded to flavonoid cores make these compounds 'super hydrophilic,' causing them to dissolve in water rather than remain with the trichome heads. The purple, yellow, and other hues in hash water come from these pigmented glycosides. Bubbleman connected this to the 2014 origin of cannabis-derived terpene extraction when K from Trichome Technologies showed Sasha Shulgin holding a vial of terpenes extracted from water, inspiring Tony and Horatio Delbert to pioneer cannabis-derived terpene isolation.
