檢測(cè)了油酸型呼吸窘迫綜合征大鼠血?dú)夂退釅A指標(biāo)的變化，并觀察了紅芪對(duì)其影響。結(jié)果表明，紅芪有提高油酸型呼吸窘迫綜合征大鼠PaO₂、O₂Sat，降低PaCO₂的作用，并能糾正大鼠酸堿的內(nèi)穩(wěn)失常，從而對(duì)紅芪治療呼吸窘迫綜合征提供了理論依據(jù)。

Yuzhizi is the seed of Akebia quinata (Thunb. ), A.trifoliota (Thunb.) Koidz.and A.trifoliata(Thunb.) Koidz.var.australis(Diels) Rehd.Two triterpenoid saponins of hederagenin 3-O-glycosides have been isolated from the seeds of A. trijoliata (Thunb.) Koidz.var.australis (Diels) Rehd. for the first time. They were idcntified by spectroscopic(EI-MS, FABMS, ¹H, ¹³CNMR and 2 DNMR) and chemical methods (acid/base hydrolysis) as Ⅰ:3-O-β-D-xylo-pyranosyl-(1-2)-α-L-arabinopyranoside hederagenin (saponin B); Ⅱ: hederagenin 3-O-β-D-glucopyranosyl-(1-2)-α-L-arabinopyranoside (saponin C).
