Phenolic compounds present in Lolium multiflorum Lam. were isolated and characterized. Significant differences in their distribution were found, in shoots and roots of plants with (Lmþ) and without (Lm ) endophyte association, grown with (Micþ) and without (Mic ) mycorrhizal fungi Glomus intraradices, indicating a systemic effect of these microorganisms on the phenolics metabolism of L. multifl...

Six new alkaloids, broussonetines W, X, M1, U1, J3, and J2 (1-6) were isolated from the branches of Broussonetia kazinoki SIEB. (Moraceae) as minor constituents. They were formulated as (2R,3R,4R,5R)-2-hydroxy-methyl-3,4-dihydroxy-5-17-(cyclohexy-2-on-1(6)-enyl)heptyllpyrrolidine (1), (2R,3S,4R,5R)-2-hydroxymethyl-3,4-dihydroxy-5-17-(cyclohexy-2-on-1(6)-enyl)heptyl]pyrrolidine-4-O-beta-D-glucop...

Abstract Prunetin (4′,5-dihydroxy-7-methoxyisoflavone) was semisynthesized in 8 steps from readily available naringenin 26% total yield. The key reaction chemoenzymatic sequential deacetylation to 6′-acetoxy-2′,4″-dihydroxy-4′-methoxychalcone, the situ-formed precursor for thallium(III) nitrate-mediated oxidative rearrangement.

Episesamin is an isomer of sesamin, resulting from the refining process of non-roasted sesame seed oil. Episesamin has two methylendioxyphenyl groups on exo and endo faces of the bicyclic skeleton. The side methylendioxyphenyl group was metabolized by cytochrome-P450. Seven metabolites of episesamin were found in rat bile after treatment with glucuronidase/arylsulfatase and were identified usin...

5,5'-Dihydroxy-2',4'-dimethoxy-7-[(6-O-β-d-apiofuranosyl-β-d-glucopyranosyl)-oxy]isoflavone (1) was isolated as the major constituent of Dalbergia vacciniifolia root bark ethanol extract together with the four known compounds 5,7-dihydroxy-2',4',5'-trimethoxyisoflavone (3), 5,7-dihydroxy-2',4'-dimethoxy-isoflavone (4), 5-hydroxy-2',4',7-trimethoxyisoflavone (5) and 7-hydroxy-2',4',5'-trimethoxy...
