Objective:
To study the chemical constituents of Myricaria paniculata.
Method:
Silica gel column chromatography was used to separate and purify the chemical constituents, and the structures were elucidated by spectral analysis.
Result:
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).
Conclusion:
All of these compounds were isolated from the genus for the first time.
