Antiviral Potential of Extracts (Prepared by Repercolation) Against Influenza A (H1N1) Virus.

An antiviral effect of extracts prepared from aerial parts of nine species and from leaves of two species of the genus L. was investigated for potential antiviral activity toward influenza A (H1N1) virus. The toxicity of dry extracts was analyzed, and the most selective extract was identified in vitro.

Chemical Composition of Methanol Extracts from Leaves and Flowers of (Ranunculaceae).

Siebold et Zucc. is an unstudied single-species genus belonging to the tribe Cimicifugeae (Ranunculaceae). The only species of this genus- Siebold and Zucc.

The Genus : Prospects of Research on Its Phytochemistry, Pharmacology, and Biotechnology.

This review summarizes information about the chemical composition and beneficial properties of species of the genus Salisb. from the world's flora. To date, seven out of ~14 species found in Asia and parts of Europe have been studied to various degrees.

Non-Targeted Screening of Metabolites in Aqueous-Ethanol Extract from (Rosaceae) Using LC-HRMS.

By means of liquid chromatography combined with high-resolution mass spectrometry, metabolite profiling was performed on an aqueous-ethanol extract from (Rosaceae) collected in Siberia (Russia). Up to 140 compounds were found in the extract, of which 47 were tentatively identified. The identified compounds were amino acids, sugars, phenylpropanoids, fatty acids and their derivatives, triterpenoids, flavonoids, and others.

Changes in Profiles of Classes and of Individual Polyphenols in Leaves of and along an Altitudinal Gradient.

Plants in high-altitude habitats are exposed to severe environmental stressors, including extreme temperatures and irradiation, which can have wide-ranging effects on changes of secondary-metabolite profiles in higher plants. Altitude-related variation of levels of polyphenols in organs of medicinal and food plant species has not yet been investigated sufficiently. This study was focused on variation in quantitative profiles of classes and of individual biologically active phenolic compounds in leaf extracts of resource species and from the family Rosaceae in coenopopulations of the Altai Mountains, along an altitudinal gradient.

Investigation of Phenolic Compounds and Antioxidant Activity of (Rosaceae) Microshoots Grown In Vitro.

is an endemic species of the Far East and Siberia and grows along the Goltsy altitudinal belt. Data on micropropagation and phytochemical characteristics of this plant are not available, probably because of the inaccessibility of the plant material. Morphogenesis initiation from flower buds of in vitro and micropropagation were performed here in the Murashige and Skoog medium supplemented with 5.

The Influence of Solid and Liquid Systems In Vitro on the Growth and Biosynthetic Characteristics of Microshoot Culture of ssp. .

The paper focuses on the growth dynamics and biosynthetic characteristics of the microshoot culture of ssp. obtained in vitro in agar-solidified and liquid media. Microshoots cultured in either type of media showed similar growth dynamics.

LC-HRMS for the Identification of Quercetin and Its Derivatives in (Rosaceae) and Anatomical Features of Its Leaves.

L. is affiliated with the section Ser. of the genus L.

Extracts of L. and L.: The Phenolic Profile and Biological Activities.

The comparative phytochemical analysis in this study revealed differences in the type and levels of phenolic compounds between L. and L. The compounds in water-ethanol extracts of aerial parts of both species were identified by high-performance liquid chromatography as chlorogenic, gentisic, and cinnamic acids; quercetin; kaempferol; hyperoside; isoquercetin; nicotiflorin; and apigenin.

Investigation of Chemical Constituents of (Ranunculaceae): Coumarins and Furochromones.

Aqueous-ethanol extracts (70%) from the leaves of Regel. (Ranunculaceae Juss.)-collected from natural populations of Kyrgyzstan-were studied by liquid chromatography with high-resolution mass spectrometry (LC-HRMS).

Identification of Flavonoids in the Leaves of (Ranunculaceae) by Liquid Chromatography with High-Resolution Mass Spectrometry (LC-HRMS).

Regel is an endemic plant of Central Asia. The flavonoid profile of leaves was studied by mass spectrometry for the first time (natural populations of Kyrgyzstan and Uzbekistan, in 70% aqueous-ethanol extracts by liquid chromatography coupled with high-resolution mass spectrometry). Mass spectrometry revealed 18 flavonoid compounds.

Phytoconstituents and Bioactivity of Plants of the Genus L. (Rosaceae): A Review.

The genus L. belongs to the Rosaceae Juss. family and includes more than 100 species distributed in the temperate zone and subtropical zone of the Northern Hemisphere at the center of species diversity in East Asia.

An integrative taxonomic approach reveals a new species of (Ranunculaceae) in North Asia.

A new endemic species, , is described from the Republic of Buryatia and Irkutsk Province, Russia. It belongs to Eranthis section Shibateranthis and is morphologically similar to and . An integrative taxonomic approach, based on cytogenetical, molecular and biochemical analyses, along with morphological data, was used to delimit this new species.

The inhibitory effect of Filipendula ulmaria (L.) Maxim. on colorectal carcinogenesis induced in rats by methylnitrosourea.

Ethnopharmacological Relevance: Meadowsweet (Filipendula ulmaria (L.) Maxim.) is a medicinal plant with a variety of therapeutic properties, traditionally used in various diseases including treatment and prevention of tumors.

Inhibitory Effect of Filipendula ulmaria on Mammary Carcinogenesis Induced by Local Administration of Methylnitrosourea to Target Organ in Rats.

Background: The meadowsweet (Filipendula ulmaria (L.) Maxim.) may have a cancer prophylactic activity, since its extracts exhibit antioxidant, anti-inflammatory and other effects.

The inhibitory effect of meadowsweet (Filipendula ulmaria) on radiation-induced carcinogenesis in rats.

Purpose: To examine the ability of the meadowsweet preparation to inhibit carcinogenesis induced by ionizing radiation in female rats.

Materials And Methods: The chemical composition of meadowsweet (Filipendula ulmaria) raw material (ethanol and aqueous extracts of meadowsweet flowers) has been studied for the presence of flavonoids, tannins and catechins. Adult female LIO strain rats were subjected to a single whole body γ-irradiation at a dose of 4 Gy in animal experiments.
