isoferulic-acid and morelloflavone

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