Briarane-type diterpenoids from the Vietnamese gorgonian Junceella fragilis
Natural Product Research, 2019 Ten briarane-type diterpenoids (1–10), including one new stereoisomer 17-epi-junceellolide B (1), were isolated from the MeOH extract of the Vietnamese gorgonian Junceella fragilis. Their structures were elucidated by spectroscopic experiments including 1D and 2D NMR, and HR-QTOF-MS.
