[Chemical Constituents from Infructescence of Platycarya strobilacea]
Objective:
To study the chemical constituents of the chloroform and acetic ether fractions from infructescence of Platycarya strobilacea.
Methods:
The compounds were isolated and purified by various chromatographic methods. Spectral analysis were taken to identify the structures.
Results:
Eleven compounds were isolated and identified as dotriacontane( 1), ursolic acid( 2),hexacosene( 3),β-sitosterol( 4),daucosterol( 5),2,5,8-trihydroxy-3-methoxy-1,4-naphthalenedione( 6),3,3’-dimethoxyellagic acid( 7),ellagic acid( 8),4’-hydroxyisoflavone-7-O-β-D-galactoside( 9),3,3’-dimethoxyellagic acid-4’-O-β-D-xylopyroside( 10), gallic acid( 11).
Conclusion:
Compounds 1,3 ~ 6,9,10 are isolated from this genus for the first time, compounds 1 ~ 6,9,10 are isolated from this plant for the first time.
