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...

Background: In this study the effect of water-alcohol Papaver bracteatum Lindl. Extract on development of mice oocytes treated with doxorubicin (dox) was examined. Materials and Methods: Mice at 7-8 weeks old were assigned to 4 groups. Control group, mice injected intraperitoneally (IP) with saline. P.bracteatum extract group alone, mice treated with 200 mg/kg of body weight, IP, twelve consecu...

Due to their easy and low-cost production enhanced properties, noble metal nanoparticles are preferred as nano-additives in most pharmaceutical compositions. For example, silver (AgNPs) gold (AuNPs) possess antiseptic antimicrobial activity they generally for obtaining antibacterial clothing coatings. In the present study, we report a simple, low cost green method synthesizing AgNPs using aqueo...

Five new species of Hypseloecus viz., Hypseloecus acutus sp. nov., Hypseloecus articulatus sp. nov., Hypseloecus belli sp. nov., Hypseloecus orientale sp. nov. and Hypseloecus spinosus sp. nov. are described from India. The genus is recorded for the first time from India collected on hemiparasitic plants of the genera Dendrophthoe and Viscum (Santalales). A key to identification of the five spe...

Plants used for treating endoand ectoparasites of rabbits and poultry in British Columbia included Arctium lappa (burdock), Artemisia sp. (wormwood), Chenopodium album (lambsquarters) and C. ambrosioides (epazote), Cirsium arvense (Canada thistle), Juniperus spp. (juniper), Mentha piperita (peppermint), Nicotiana sp. (tobacco), Papaver somniferum (opium poppy), Rubus spp. (blackberry and raspbe...

this study was designed to examine the chemical composition and in-vitro antioxidant activity of the essential oil and methanolic extract of teucrium orientale subsp. taylori. the gc and gc–ms analysis of the essential oil resulted in determination of 40 components representing 96.4% of the oil. the major constituents of the oil were linalool (28.6%), caryophyllene oxide (15.6%), 1,8-cineol (4....

Four native Papaver species of Iran, i. e. P. glaucum, P. tenuifolium, P. dubium and P. fugax, were collected from their natural habitat and subjected to HPLC analysis for determination of their morphine, codeine and thebaine content. P. dubium and R. glaucum contained all of the three mentioned narcotic alkaloids, while morphine was not found in P. fugax, and P. tenuifolium was free from codeine.

INTRODUCTION Lignans and flavonoids are widely distributed phenolics in the plant kingdom. Aryltetralin type lignans (podophyllotoxin derivatives) as the major secondary metabolites of Linum species play an important role in the production of chemotherapy drugs. In the present study, lignans and flavonoid glycosides from aerial parts of Linum mucronatum subsp. orientale were isolated and identi...
