[Studies on chemical constitutes of Acantophora spicifera].
OBJECTIVE
To study the chemical constitutes of Acantophora spicifera.


METHODS
Compounds were isolated by normal phase silica gel and Sephadex LH-20 gel column chromatography, and reverse-phase HPLC, as well as recrystallization. Their structures were elucidated by spectroscopic methods.


RESULTS
Seven compounds were isolated from A. spicifera and their structures were identified as aplysin (1), loloilide (2), (R)-(-)-dehydrovomifoliol (3), uracil (4), thymine (5), 1-methoxy-4-(1-propenyl) benzene (6).


CONCLUSIONS
The compounds were obtained from this genus for the first time. Compound 6 was firstly obtained from marine organisms.
