Five new [daphneodorins D-H (, , and -)] and seven known daphnane diterpenoids (- and -) were isolated from . The structures of the new compounds were elucidated by extensive physicochemical and spectroscopic analysis. The isolated compounds were evaluated for their anti-HIV activity against HIV-1 infection of MT4 cells. Nine daphnane diterpenoid orthoesters (-) showed potent anti-HIV activity with EC values of 1.5-7.7 nM.
