Abstract:
Fifteen compounds were isolated from the 70% EtOH extract of leaves of Chinese hawthorn(Crataegus pinnatifida var. major) by various purification steps, and their structures were determined as 2α,3α,12β,19α,-tetrahydroxyursan-13β,28-olide(1),euscaphic acid(2), tormentic acid(3), ursolic acid(4), pomolic acid(5), corosolic acid(6), maslinic acid(7), linalyl rutinoside(8),(Z)-3-hexenyl β-D-glucoside(9),(3S, 6S)-cis-linalool-3,7-oxide-β-D-glucopyranoside(10), pisumionoside(11), icariside B6(12), byzantionoside B(13),(6R,7E,9R)-9-Hydroxy-4,7-megastigmadien-3-one 9-O-β-D-glucopyranoside(14) and(6S,7E,9R)-6,9-dihydroxy-4,7-megastigmadien-3-one 9-O-β-D-glucopyranoside(15) mainly based on the mass spectrum(MS) and nuclear magnetic resonance(NMR) spectroscopic techniques, of which compound 1 was a new pentacyclic triterpene, and compounds 2, 5, 6, 8, 10, 13 and 15 were isolated form this plant for the first time.
