title: New sesquiterpenoid glycoside and phenylpropanoid glycosides from the tuber of Ophiopogon japonicus.
abstract: A new sesquiterpenoid glycoside, cryptomeridiol 11-O-β-d-xylopyranosyl-(1→6)-β-d- glucopyranoside (1), two new phenylpropanoid glycosides, 3,4-dihydroxy-allylbenzene 3-O-β-d-glucopyranosyl-4-O-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (2), and 3,4,5-trihydroxy-allylbenzene 3-O-β-d-glucopyranosyl-4-O-β-d-glucopyranoside (3), along with four known phenylpropanoid glycosides (4-7), were isolated from the tuber of Ophiopogon japonicus. Compounds 4-7 were obtained from the genus Ophiopogon for the first time. Their structures were elucidated by spectroscopic methods, including 1D and 2D NMR and HR-ESI-MS.
