摘要:
A new triterpenoid glycoside(1) and seven known triterpenoid glycosides, pseudoginsenoside RT2(2), yesanchinoside R2(3), vinaginsenoside R13(4), vinaginsenoside R8(5), notoginsenoside E(6), 6'''-O-acetylginsenoside Re(7), 6"-O-acetylginsenoside Rb1(8), were isolated from the rhizomes of Panacis majoris. The new triterpenoid glycoside was elucidated as 3-O-[β-D-glucopyranosyl-(1→2)-β-D-(6'-O-ethyl)-glucuronopyranosyl]-oleanolic acid-28-O-β-D-glucopyranoside by extensive spectroscopic and phytochemical methods. Compounds 2-8 were obtained from the plant for the first time. Compounds 3 and 4 displayed good activities against adenosine diphosphate (ADP)-induced platelet aggregation, and compounds 1, 5, 6 and 8 showed moderate activities. Compound 6 exhibited moderate antiplatelet aggregation activity induced by arachidonic acid(AA).
