Purpose: To isolate and identify the chemical components of
Paraoncidium reevesii
.
Methods: Silica gel column chromatography was used to isolate the components from petroleum ether
and ethyl acetate fractions of the acetone extract, and the structures of the compounds were derived
from
1H-nuclear magnetic resonance (
1H-NMR),
13C-nuclear magnetic resonance (
13C-NMR) and mass
spectrometry (MS) analyses and also with the aid of literature data for authenticated samples.
Results: Cholesterol (1), baconipyrone D (2), chimyl alcohol (3), batyl alcohol (4), α-monpalmitin (5),
stearic acid (6), 3-indolecarboxylic acid (7), uracil (8), thymine (9), uridine (10), thymidine (11) were
isolated from the marine slug (
Paraoncidium reevesii).
Conclusion: All the isolated compounds are being reported here for
Paraoncidium reevesii for the first
time. The results provide base data for further study of the
Onchidiidae as a Chinese traditional remedy
for asthma and athlete’s foot.
