• Bioactive Pimarane Diterpenes from the Arctic Fungus Eutypella sp. (deepdyve.com)
  • 5 During our research on S. divinorum , salvinorin A was first isolated from a single pharmacologically active TLC band using a solvent system of 100/10/1 CHCl 3 /MeOH/H 2 O. Differences in potency between the purified diterpene and the original TLC fraction led us to surmise that the latter contained other strongly bioactive compounds that co-chromatographed with salvinorin A during the chromatographic separation.
