[Study on chemical constituents of Myricaria paniculata I].
OBJECTIVE
To study the chemical constituents of Myricaria paniculata.


METHODS
Silica gel column chromatography was used to separate and purify the chemical constituents, and the structures were elucidated by spectral analysis.


RESULTS
Four compounds were isolated from the petroleum ether soluble portion, identified as 28-aldehyde-taraxerenone (1), 28-hydroxy-taraxerenone (2), epi-friedelanol (3), 4-methyl stigmast-7-en-3-ol (4). Three compounds were isolated from the EtOAc soluble portion, identified as morelloflavone (5), methyl 3, 5-dihydroxy-4-methoxybenzoate (6), 3-hydroxy-4-methoxy cinnamic acid (7).


CONCLUSIONS
All of these compounds were isolated from the genus for the first time.
