Two new C_(27)-steroidal glycosides were isolated from the fibrous roots of Ophiopogon japonicus.The spectral analysis and chemical evidence revealed their chemical structures to be(25R)-spirost-5,14-dien-3β-yl-O-α-L-rhanmopyranosyl-(1→2)-β-D- xylopyranosyl-(1→4)-β-D-glucopyranoside(1)and ophiogenin 3-O-β-D-glucopyranoside(2).
