[Studies on chemical constituents of green algae Ulva pertusa].
OBJECTIVE
To study the compounds from Ulva pertusa.


METHODS
The alga was extracted with ethanol, isolated and purified by column chromatography on silica gel and sephadex LH -20. All the compounds were identified on the basis of spectral analysis (including IR, MS, NMR).


RESULTS
Seven compounds were elucidated as cis-asarone (1), trans-asarone (2), gamma-asarone (3), trans-phytol (4), phytyl-stearate (5), phytyl-acetate (6), isophytol (7).


CONCLUSIONS
All other compounds were isolated for the first time from U. pertusa, except for the compound 4.
