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).
Conclusion:
Compounds 1 - 10 are obtained from this plant for the first time.
