Many species in the genus Silene (Caryophyllaceae) have previously been shown to contain ecdysteroids and this genus is recognised as a good source of novel ecdysteroid analogues. We have used ecdysteroid-specific radioimmunoassays and the microplate-based Drosophila melanogaster B(II) cell bioassay for ecdysteroid agonist and antagonist activities to(More)
Certain genera within the Caryophyllaceae (especially Silene and Lychnis) have received a significant amount of attention with regard to the isolation and identification of ecdysteroids. However, the taxonomy of this family is difficult. Hence, the occurrence of phytoecdysteroids in members of the Caryophyllaceae is presented, and combined with new data on(More)
The phytoecdysteroid profiles of extracts of aerial parts of flowering plants of 7 ecdysteroid-containing species in the genus Silene (Caryophyllaceae; S. fridvaldszkyana Hampe, S. gigantea L., S. graminifolia Otth, S. mellifera Boiss. & Reuter, S. repens Patr., S. schmuckeri Wettst., and S. sendtneri Boiss.) have been examined and identified by HPLC and,(More)
Distribution of phytoecdysteroids is analyzed in the family Caryophyllaceae, which includes a large number of ecdysteroid-containing species. Species of this family synthesize a wide variety of steroid compounds, insect molting and metamorphosis hormones, many of which are not found in other plants. Most of the species of Caryophyllaceae are characterized(More)
Anti-inflammatory and analgesic activities of the complex of flavonoids from Lychnis chalcedonica L. were studied in the models of acute aseptic inflammation induced by carrageenan, histamine, and serotonin and acetic acid-induced painful chemical stimulation. It is demonstrated that course treatment with flavonoids derived from Lychnis chalcedonica L.(More)
A novel ecdysteroid-containing pharmaceutical substance – Lychnis chalcedonica extract – was developed. The phytoecdysteroid composition of the ethanolic extract was determined. Courses of intragastric administration of Lychnis chalcedonica extract (150 mg/kg) were accompanied by anabolic effects in both trained and untrained animals. The actoprotector(More)
We have investigated the epigeal mass of wild-growing plants of the genus Lychnis and of plants of this genus introduced into the Siberian Botanical Garden (Tomsk University) [4]. In the present communication we give the results of an investigation of two species: the wild-growing L. wilfordii (Regel.) Maxim (Wilford's campion) and the introduced species L.(More)
We studied antiulcer activity of the extracts of ecdysteroid-containing plants of the Caryophyllaceae family: Lychnis chalcedonica L., Silene viridiflora L.Sp.Pl., and Silene frivaldszkyana Hampe. Experiments on the model of neurogenic and aspirin-induced ulcerogenesis showed unidirectional and pronounced gastroprotective effects of S. viridiflora and L.(More)
