[Study on the chemical constituents from ethyl acetate extract of Micromelum falcatum].
OBJECTIVE
To study the chemical constituents from ethyl acetate extract of Micromelum falcatum.


METHODS
The constituents were separated and purified by silica gel, Sephadex LH-20 and HPLC. Their structures were elucidated by spectral analysis (NMR, MS).


RESULTS
Ten compounds were isolated and identified as micropubescin (1), phebalosin (2), scopoletin (3), citrubuntin (4), thamnosmonin (5), hopeyhopin (6), arnottinin (7), casegravol (8), 2-methoxy-5-hydroxy cinnamate (9), threo-syringoylglycerol (10).


CONCLUSIONS
Compounds 1 - 10 are obtained from this plant for the first time.
