L-amino acid oxidase (LAAO) is attracting more attentions due to its broad and important biological functions. Recently, an LAAO-producing marine microorganism (strain B3) was isolated from the intertidal zone of Dinghai sea area, China. Physiological, biochemical, and molecular identifications together with phylogenetic analysis congruously suggested that… (More)
A new phenylethanoid, 1-O-β-d-(4-hydroxyphenyl)-ethyl-6-O-vanilloyl-glucopyranoside (1), and a new furofuran lignan, (7R,7′R,7′′S,8S,8′S,8′′R)-4′, 4′′-dihydroxy-3,3′,3′′,5-tetramethoxy-7,9′:7′9-diepoxy-4,8′′-oxy-8,8′-sesquineolignan-7′′,9′′-diol (2), along with five known compounds (3–7) were isolated from the roots of Ilex pubescens. Their chemical… (More)
Two new compounds, 2″-O-feruloylisoswertiajaponin (1) and (2E)-2-methyl-1-O-vaniloyl-4-β-d-glucopyranoside-2-butene (2), along with one indole alkaloid and five known flavonoids, were isolated from the flowers of Trollius chinensis Bunge. Their structures were elucidated on the basis of spectroscopic evidence (UV, IR, HR-ESI–MS, NMR).
