[Two new phenylethanoid glycosides from Corallodiscus flabellata].

Aim: To study the chemical constituents from Corallodiscus flabellata.

Methods: Fresh plant of Corallodiscus flabellata was extracted twice with boiling water, filtered to remove insoluble materials, concentrated under reduced pressure at temperature 55 degrees C to a small volume. The concentrated liquor was subjected to solvent-solvent partitioning using ether, ethyl acetate, and n-butanol (saturated with water).

[Isolation and structural identification of phenylethanoid glycosides from Corallodiscus flabellata].

Aim: To study the chemical constituents from Corallodiscus flabellata.

Methods: The compounds were isolated and purified by macroporous adsorption resin, silica gel column chromatography and identified on the basis of their physiochemical and spectral data.

Results: Three phenylethanoid glycosides (I-III) were obtained from the n-BuOH fraction of water-extracts.
