چکیده

A chemical investigation of the Orchidaceae Arundina gramnifolia has led to the isolation of a novel stilbenoid, named arundinan (1). The structure of 1 has been elucidated as 2-(p-hydroxybenzyl)-3-hydroxy-5-methoxybibenzyl on the basis of physical and chemical evidence and spectral analysis.

Two New Stilbenoids from the Aerial Parts of Arundina graminifolia (Orchidaceae).

Two new phenanthrene derivatives, a phenanthrenequinone named arundiquinone (1) and a 9,10-dihydrophenanthrene named arundigramin (2) together with a known lignin dimer (3) and seven known stilbenoids (4-10) were isolated from the aerial parts of the Asian orchid Arundina graminifolia. The structures of the isolated compounds were elucidated by spectroscopic methods, including extensive 1D, 2D ...

Vittaria graminifolia (Pteridaceae) and Didymoglossum petersii (Hymenophyllaceae) in Broxton Rocks, GA

—We report on the occurrence of independent gametophytes of Didymoglossum petersii and both gametophytes and sporophytes of Vittaria graminifolia in the Broxton Rocks Preserve of southern Georgia. This is the first time sporophytes of V. graminifolia have been observed in the United States. In order to unambiguously identify both taxa, we extracted DNA for each. In the case of V. graminifolia, ...

Evaluation of the Combined Effects of Stilbenoid from Shorea gibbosa and Vancomycin against Methicillin-Resistant Staphylococcus aureus (MRSA)

The aim of this study is to determine the combined effects of stilbenoids from Shorea gibbosa and vancomycin against methicillin-resistant Staphylococcus aureus (MRSA). A total of nine pure compounds, five stilbenoid dimers ε-viniferin, ampelopsin A, balanocarpol, laevifonol and diptoindonesin G and four stilbenoid trimers a-viniferin, johorenol A, ampelopsin E and vaticanol G were evaluated fo...

Silver(I) complexation of (poly)aromatic ligands. Structural criteria for depth penetration into cis-stilbenoid cavities.

Silver(I) complexes with aromatic donors are thoroughly analyzed (with aid of the Cambridge Crystallographic Database) to identify the basic structural factors inherent to the bonding of an arene ligand. Most strikingly, the distance parameter d (which simply measures the normal separation of Ag from the mean aromatic plane) is singularly invariant at d = 2.41 +/- 0.05 A for all silver/arene co...
