To isolate and identify the chemical components of Paraoncidium reevesii
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
H-nuclear magnetic resonance (1
C-nuclear magnetic resonance (13
C-NMR) and mass
spectrometry (MS) analyses and also with the aid of literature data for authenticated samples.
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
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.
