Journal ArticleDOI
Analysis of the antinociceptive effect of the flavonoid myricitrin: evidence for a role of the L-arginine-nitric oxide and protein kinase C pathways.
Flavia Carla Meotti,Ana Paula Luiz,Moacir Geraldo Pizzolatti,Candida Aparecida Leite Kassuya,João B. Calixto,Adair R.S. Santos +5 more
TL;DR: The results indicate that myricitrin produces pronounced antinociception against chemical and mechanical models of pain in rodents and seems to involve an interaction with nitric oxide-l-arginine and protein kinase C pathways.
Journal ArticleDOI
Cytotoxic Lavandulyl Flavanones from Sophora flavescens
Tai Hyun Kang,Sei Joon Jeong,Won Gil Ko,Na-Young Kim,Byung-Hoon Lee,Masanori Inagaki,Tomofumi Miyamoto,Ryuichi Higuchi,Youn-Chul Kim +8 more
TL;DR: Two new lavandulylated flavanones were isolated from the root of Sophora flavescens and exhibited cytotoxic activity against human myeloid leukemia HL-60 cells.
Journal ArticleDOI
A Journey of Twenty-Five Years through the Ecological Biochemistry of Flavonoids
TL;DR: The ecological biochemistry of flavonoids, in which I have been engaged for 25 years, is summarized in this review article.
Journal ArticleDOI
Xanthones and Benzophenones from the Stems of Garcinia multiflora
TL;DR: The structures of 1-5 were elucidated by extensive analysis of their spectral data and were evaluated in the brine shrimp lethality test and in the DPPH antioxidant assay.
Journal ArticleDOI
Steroidal saponins from the bark of Dracaena draco and their cytotoxic activities.
Antonio G. González,Juan Carlos Martín Hernández,Francisco León,Juan I. Padrón,Francisco Estévez,José Quintana,Jaime Bermejo +6 more
TL;DR: From the stem bark of Dracaena draco, three new compounds, namely, draconins A-C (1-3), were isolated, along with 17 known compounds, whose structures were elucidated on the basis of spectroscopic data interpretation.

The carbon-13 nuclear magnetic resonance spectra of flavonoids and related compounds
A. Pelter,R.S. Ward,T.I. Gray +2 more
TL;DR: It is shown that the acetylation of phenolic Hydroxy-group can be used to identify the positions of the hydroxy-groups on an aromatic ring, a technique which is particularly useful when both hydroxy and methoxy-groups are present.
Journal ArticleDOI
13C NMR spectroscopy of coumarin derivatives
Helmut Duddeck,Manfred Kaiser +1 more
TL;DR: In this article, the 13C chemical shifts of 209 naturally occurring and synthetic coumarin derivatives are discussed and a number of methods for signal assignment are explained, including substitutions and nonadditivities.
Journal ArticleDOI
13C-NMR spectroscopy of biflavanoids
V.M. Chari,V.M. Chari,Mohammed Ilyas,Mohammed Ilyas,Hildebert Wagner,Hildebert Wagner,András Neszmélyi,András Neszmélyi,Chen Fa-Ching,Chen Li-Kuang,Lin Yu-Chin,Lin Yu-Meei +11 more
TL;DR: In this article, the 13 C-NMR spectra of nine naturally occurring C-C linked biflavanoids have been assigned and the level of oxidation of the ring C can be readily determined by a consideration of the chemical shift value of the carbonyl resonances.

Biflavonoids in Hypericum perforatum1; Part 1. Isolation of I3, II8-Biapigenin.
R Berghöfer,J Hölzl +1 more
TL;DR: From the Soxhlet extract of HYPERICUM PERFORATUM, biflavonoids have been isolated by column chromatography on Sephadex LH 20 and preparative TLC and the structure was elucidated by UV-, (1)H- and (13)C-NMR spectroscopy and MS as I3,II8-Biapigenin.
Journal ArticleDOI
13C NMR and CD of some 3,8″-biflavanoids from Garcinia species and of related flavanones
TL;DR: In this paper, the 13C NMR signals for most of the carbon atoms of some 3,8″-biflavanoids were assigned with the help of the spectra of the corresponding monomers.
