ABSTRACT
The present study analyzed the chemical constituents in dried roots of Dolomiaea souliei. Chromatographic methods, such as normal-phase, and reversed-phase column chromatography, TLC, and preparative HPLC, were applied to separate and purify the petroleum ether extract of D. souliei. The structures of the purified constituents were identified by multiple spectroscopic methods including 1 D NMR, 2 D NMR, IR, UV, and HR-ESI-MS. Fourteen triterpenoids were obtained and identified as bauer-8-ene-3,11-dione-7α-ol(1), bauer-8-ene-3-one-7α,11α-diol(2), 3-oxo-11α-hydroxy-urs-12-ene(3), 3-oxour-12-ene-1ß,11α-diol(4), 3ß,11α-dihydroxy-urs-12-ene(5), taraxast-20-ene-3ß,30-diol(6), 28-hydroxy-3-oxo-12-ursene(7), 3ß-hydroxytaraxast-20-ene-30-aldehyde(8), urs-12-ene-2α,3ß,28-triol(9), 20-hydroxylupan-3-one(10), monogynol A(11), obtusalin(12), 3-oxo, 11α-hydroxy-olean-12-ene(13), and isocabralealactone(14). Among them, compounds 1 and 2 were new compounds. Compounds 4-10, 12, and 14 were isolated from this genus for the first time. Compounds 3 and 11 were obtained from D. souliei for the first time.
