摘要
对川木香属植物川木香Dolomiaea souliei的干燥根进行化学成分研究。综合运用正相与反相柱色谱、TLC、制备HPLC等色谱方法对川木香石油醚部位进行分离纯化,采用1D和2D NMR、IR、UV、HR-ESI-MS等技术手段进行结构鉴定。最终,分离得到14个三萜类化合物,分别为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-1β,11α-diol (4)、3β,11α-dihydroxy-urs-12-ene (5)、taraxast-20-ene-3β,30-diol (6)、28-hydroxy-3-oxo-12-ursene (7)、3β-hydroxytaraxast-20-ene-30-aldehyde (8)、urs-12-ene-2α,3β,28-triol (9)、20-hydroxylupan-3-one (10)、monogynol A (11)、obtusalin (12)、3-oxo, 11α-hydroxy-olean-12-ene (13)、isocabralealactone (14)。其中,化合物1和2为新化合物,化合物4~10、12、14为首次从川木香属植物中分离得到,化合物3和11为首次从川木香植物中分离得到。
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 1D NMR, 2D 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-1β,11α-diol(4), 3β,11α-dihydroxy-urs-12-ene(5), taraxast-20-ene-3β,30-diol(6), 28-hydroxy-3-oxo-12-ursene(7), 3β-hydroxytaraxast-20-ene-30-aldehyde(8), urs-12-ene-2α,3β,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.
