Six new naturally occurring polyoxygenated cyclohexene derivatives together with eight related known derivatives,
two known alkaloids, and two known flavonoid derivatives were isolated from bioassay-guided fractionation
of the ethyl acetate extract of the leaves and twigs of Dasymaschalon sootepense. The structure
elucidation and determination of absolute configurations were established by various spectroscopic methods,
X-ray diffraction techniques as well as comparison with the literature data. Several isolated compounds were
evaluated for their cytotoxic, anti-HIV-1 RT and anti-inflammatory activities.
