In vitro anti-inflammatory activity of larch (Larix decidua L.) sawdust.
TLDR
The influence of larch (Larix decidua L.) sawdust extracts on arachidonate metabolism has been evaluated in vitro and compounds possessing a 7,13-abietadiene skeleton were better inhibitors of LTB(4) formation than those with an 8,11,13 -abietatriene skeleton. Expand
Trimethylsilyldiazomethane – A Mild and Efficient Reagent for the Methylation of Carboxylic Acids and Alcohols in Natural Products
Summary.Esterification of various naturally occurring carboxylic acids with trimethylsilyldiazomethane proceeds nearly quantitatively under very mild conditions. Furthermore, highly stericallyExpand
Sesquiterpenes and Flavonoid Aglycones from a Hungarian Taxon of the Achillea millefolium Group
TLDR
The investigation of a dichloromethane extract of flower heads of a Hungarian taxon of the Achillea millefolium group led to the isolation of three flavonoid aglycones, one triterpene, one germacranolide and five guaianolides, which are reported here for the first time. Expand
Sulfemodin 8-O-beta-D-glucoside, a new sulfated anthraquinone glycoside, and antioxidant phenolic compounds from Rheum emodi.
TLDR
A sulfated emodin glucoside was isolated from the roots of Rheum emodi in an investigation of the active constituents of this Nepalese medicinal plant, and its structure was determined by spectroscopic and chemical methods. Expand
Antiplasmodial and leishmanicidal activity of biflavonoids from Indian Selaginella bryopteris
Abstract A series of eleven biflavonoids containing amentoflavone and hinokiflavone derivatives from the Indian medicinal herb Selaginella bryopteris has been investigated for their antiprotozoalExpand
Anthrone C-glucosides from Rheum emodi.
TLDR
In a study of the anthraderivatives in roots of Rheum emodi, three new anthrone C-glucosides were isolated and an acetylated chrysophanol glucoside was isolated, established by comprehensive spectroscopic investigations. Expand
High-Yield Syntheses of Tetra-O-benzyl-α-D-glucopyranosyl bromide and Tetra-O-pivaloyl-α-D-glucopyranosyl bromide and their Advantage in the Koenigs-Knorr Reaction
Summary.Several improved approaches for the preparation of tetra-O-benzyl-α-D-glucopyranosyl bromide and tetra-O-pivaloyl-α-D-glucopyranosyl bromide are discussed. The importance of these compounds,Expand
Flavonoid C- and O-glycosides from the Mongolian medicinal plant Dianthus versicolor Fisch.
TLDR
Eighteen flavonoids were identified from an aqueous extract of the aerial parts of Dianthus versicolor, a plant used in traditional Mongolian medicine against liver diseases, with a high glycosylation pattern rare within the genus Dianthus. Expand
Influence of structure and chirality of the selector on the chiral recognition of amino acids using ligand‐exchange capillary electrophoresis
TLDR
The investigations were carried out with three aromatic amino acids as model compounds and the effect of surfactants such as sodium dodecyl sulfate and cetyl trimethyl ammonium bromide on resolution and enantiomer migration order is studied. Expand
Phenolic and terpenoid compounds from Chione venosa (sw.) urban var. venosa (Bois Bandé).
The Caribbean island of Grenada furnishes the popular aphrodisiac drug Bois Bandé, which consists of the stem bark and the roots of Chione venosa (sw.) URBAN var. venosa (Rubiaceae), a native treeExpand
