WebSep 4, 2006 · A novel triterpene, 2α,3β,20,23-tetrahydroxyurs-28-oic acid ( 1 ), was isolated from the aerial part of Centella asiatica. Its structure was elucidated by spectroscopic methods, including 2D-NMR spectra. It displayed no activity against Hela and A549 cell lines at concentrations of 10 and 30 μg/mL, respectively. WebToyopearl HW-55 is for rather large proteins, HW-45 might be more appropriate (but you can not know until you try...). Packing SEC columns is an art (to avoid preferential pathways) but it is...
