ABSTRACT
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),ß-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-ß-D-galactoside( 9),3,3'-dimethoxyellagic acid-4'-O-ß-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.
ABSTRACT
OBJECTIVE: To analyse the compositions of essential oil from leaves of Discocleidion rufescens. METHODS: To isolate by steam distillation and analyze by GC-MS. RESULTS: 37 compounds, representing 92.25% of total oil were indentified and their relative amount was determined. CONCLUSION: The oil is rich in Phytol (39.30%, n-Hexadecanoic acid (11.72%), (Z) -3-Teoadecen-5-yne (5.78%) and beta-Pinene (3.63%).
