From the underground parts of Thalictrum orientale Boiss., a new phenolic compound 1 was isolated in addition to one known cyanoglycoside, lithospermoside (2). For the structure elucidation of all compounds, 1D- and 2D-NMR techniques (DEPT, COSY, HMBC, HSQC) and MS (HR-MALDI) were used. The structure of the new compound was established as 2-(4'-hydroxyphenyl)-nitroethane-4'-O-[beta-xylopyranosy...

The discovery of ancient whole-genome duplications in eukaryotic lineages has renewed the interest in polyploidy and its effects on the diversification of organisms. Polyploidy has large-scale effects on both genotype and phenotype and has been linked to the evolution of genome size, dioecy, and changes in ecological interactions, such as pollinator visitation. Here, we take a molecular systema...

Four new triterpene glycosides were isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). They were designated as squarroside I, being a cycloartane-type glycoside, and squarrosides II, III and IV, being oleanene-type glycosides. Their structures were established by using two dimensional (2D) NMR techniques.

A new dolabellane diterpene glycoside, named squoside A, and three new cycloartane glycosides, named squarrosides V, VI, and VII, have been isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.

Thalictrum is a well recognised genus of medicinal plants. It is widely distributed in temperate and tropical habitats of India. Alkaloid isomers from Thalictrum are reported to exhibit various pharmacological activities like antiamebic, antimicrobial, antitumour and antiviral. Thalictrum reniforme Wallich and Thalictrum neurocarpum Royale are very less studied species of the genera. In present...

Perennial woodland herbs in the genus Thalictrum exhibit high diversity of floral morphology, including four breeding and two pollination systems. Their phylogenetic position, in the early-diverging eudicots, makes them especially suitable for exploring the evolution of floral traits and the fate of gene paralogs that may have shaped the radiation of the eudicots. A current limitation in evolut...

Meadow Rues Richard G. Hawke

(Thalictrum)—their delicate flowers, handsome foliage and graceful habits—are treasured by many gardeners. From the diminutive T. kiusianum to the titanic T. pubescens, they possess a distinctive charm. Meadow rues are a diverse group of perennials well-suited to a variety of garden settings including sunny borders, woodlands and rockeries. The wealth of meadow rues available to gardeners ensur...

The floral organ identity gene APETALA3 (AP3) is a MADS-box transcription factor involved in stamen and petal identity that belongs to the B-class of the ABC model of flower development. Thalictrum (Ranunculaceae), an emerging model in the non-core eudicots, has AP3 homologs derived from both ancient and recent gene duplications. Prior work has shown that petals have been lost repeatedly and in...

Fast-growing European buckthorn (Rhamnus cathartica) shrubs are aggressively invading woodlands in eastern and midwestern North America. Buckthorn casts dense shade, alters soil conditions, and may be allelopathic. We used greenhouse and field experiments to investigate aboveand belowground effects of Rhamnus on four herbaceous species native to southern Wisconsin. In the greenhouse, we assesse...
