Publication date: February 2019Source: Phytochemistry Letters, Volume 29Author(s): Chutima Srinroch, Poolsak Sahakitpichan, Nitirat Chimnoi, Somsak Ruchirawat, Tripetch KanchanapoomAbstractA new neolignan glycoside, (7R,8S)-7′-hydroxy-dihydrodehydrodiconiferyl alcohol 9-O-β-d-glucopyranoside (monthaphuoside A, 1) and a new monoterpene glycoside, (3R,6Z)-9-hydroxylinaloyl 3-O-β-d-glucopyranoside (monthaphuoside B, 2), were isolated from the leaves of Magnolia henryi along with (3R,6S)-6,7-dihydroxy-6,7-dihydrolinaloyl 3-O-β-d-glucopyranoside, hodgsonialloside C, syringin, 3,4,5-trimethoxyphenyl-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside, (+)-syringaresinol O-β-d-glucopyranoside, kaempferol 3-O-neohesperidoside, kaempferol 3-O-α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→6)]-β-d-glucopyranoside, rutin, quercetin 3-O-α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→6)]-β-d-glucopyranoside, 3-hydroxy-5,6-epoxy-β-ionol 3-O-β-d-glucopyranoside, (6S,9R)-roseoside, (6R,9R)-3-oxo-α-ionol β-d-glucopyranoside, byzantionoside B, citroside A, and bridelionoside B. The structure elucidation of these compounds was based on analyses of physical and spectroscopic data including 1D and 2D NMR experiments.Graphical abstractA new neolignan and a new monoterpene glycosides were isolated from Magnolia henryi.
