[Study on chemical constituents of tress of Toona ciliata].

OBJECTIVE

To study the chemical constituents of the tress of Toona ciliata.

METHODS

The compounds were isolated by many kinds of chromatography methods and identified on the basis of physico-chemical characters and spectroscopic analysis.

RESULTS

Seven compounds were obtained from the petrol and chloroform extracts of the tress of Toona ciliata, and their structures were identified as 3-Acetoxy-17-furan-3-yl-1-hydroxy-1, 4, 4, 10, 13-pentamethyl-12-oxo-tetradecahydro-16, 20-dioxa-cyclopropa [14, 15] cyclopenta [alpha] phenanthrene-7-carboxylic acid methyl ester (I), beta-sitosterol (II), stigmasterol (III), n-C35H72 (IV), palmitinic acid (V), n-C20H42 (VI), 3-(3-Propyl-[1,1',3',1"]tercyclohexan-3"-yl)-propan-1-ol (VII).

CONCLUSION

Compounds I, IV, VI, VII are isolated from this plant for the first time and compound I is a new compound.
