[Studies on chemical constituents of aerial roots of Ficus microcarpa].
OBJECTIVE
To investigate the chemical constituents of the aerial roots of Ficus microcarpa.


METHODS
The solvent extraction and silica gel and Sephadex LH-20 column chromatography were used to isolate and purify the constituents. The chemical structures were elucidated by physicochemical properties and the analysis of spectroscopic data.


RESULTS
Eight compounds were obtained and identified as (2S, 3S, 4R) -2-[(2'R) -2' - hydroxypentracosanoylamino]- heptadecane -1, 3, 4-triol (1), 12, 20 (30) -ursa-dien-3alpha-ol (2), epifriedelanol (3), alpha-amyrin acetate (4), beta-sitosterol (5), beta-daucosterol (6), hexacosanoic acid (7), heneicosanoic acid (8), respectively.


CONCLUSIONS
Compound 1 was a new compound and named as microcarpaceramide A. Compound 2 was isolated from the aerial roots of F. microcarpa for the first time.
