A new dibenzocyclooctadiene lignan named angustifolin D (1) together with four known lignans: kadsulignan L (2), kadsulignan N (3), schisantherin P (4) and meso-dihydroguaiaretic acid (5) were isolated from the stems of Kadsura angustifolia. Their structures and stereochemistries were elucidated by spectral studies. Compounds 2 and 5 showed moderate platelet-activating factor (PAF) antagonistic...

Elaeagnus angustifolia L. is a drought-resistant species. Arbuscular mycorrhizal symbiosis is considered to be a bio-ameliorator of saline soils that can improve salinity tolerance in plants. The present study investigated the effects of inoculation with the arbuscular mycorrhizal fungus Rhizophagus irregularis on the biomass, antioxidant enzyme activities, and root, stem, and leaf ion accumula...

Seeds from five lots each of Echinacea angustifolia DC, and E. pallida (Nutt.) Nutt. were germinated in a growth chamber in light (40 μmol·m(-2)· s(-1)) or darkness at 25 °C for 16 to 20 d after soaking in 1 mM ethephon or water for 10 min, or moist stratification at 4 - 6 °C for two weeks. Either light or ethephon promoted seed germination of E. angustifolia and E. pallida, in comparison with ...

Somatic embryogenesis has been shown to be an efficient tool for studying processes based on cell growth and development. The fine regulation of the cell cycle is essential for proper embryo formation during the process of somatic embryogenesis. The aims of the present work were to identify and perform a structural and functional characterization of Mps1 and to analyze the effects of the inhibi...

INTRODUCTION Dysbiosis is associated with a number of gastrointestinal and systemic disorders. There is a need for selectively acting antimicrobial agents capable of inhibiting the growth of potentially pathogenic microorganisms, or those found to be out of balance, while not negatively impacting the bulk gastrointestinal tract microflora. OBJECTIVE The purpose of this in vitro study is to ex...

The pollen cone and the pollen grain of the two Argentinean species of Araucaria are described with LM, SEM and TEM. Primordia of pollen cones are formed in April and May and reach maturity by mid-October in A. angustifolia (Bert.) O. Kuntze and by mid-November in A. araucana. (Mol.) K. Koch. Characters of the mature pollen cones and microsporophylls between both taxa are clearly differentiated...

Article history: Received on: 09/06/2014 Revised on: 17/07/2014 Accepted on: 04/08/2014 Available online: 27/08/2014 The present study was attempted to evaluate diuretic potency of total alcoholic extracts and its polar and non polar fractions of Priyala fruits (Buchanania angustifolia, Buchanania lanzan Fam: Anacardiaceae) in rats. Healthy adult Wistar albino rats weighing about 150-200 g were...

Radiotherapy, a highly effective way to destroy breast cancer, causes skin adverse effects. A considerable amount of studies have been conducted to find a way to alleviate or relieve dermal adverse effects of radiation. The aim of this study was to observe the clinical effect of Elaeagnus angustifolia L. cream to treat radiotherapy-induced skin destruction in breast cancer patients. thirt...

Using surveys of natural populations, experimental crosses, and common garden trials, we tested the hypothesis that hybrid cottonwoods (Populus fremontii × P. angustifolia) from the Weber River in northern Utah would produce as many viable offspring as their parental species. We found that both F(1) generations and backcross generations can be just as fit as the parent taxa. First, F(1) hybrids...
