in this research,for taxonomic studies and identification of the fungi associated with the powdery mildew(oidium euonymi- japonici) of buxus trees (euonymus japonica), the infected leaves were collected during autumn and winter 2012-2013 in gorgan (golestan province -iran). the samples after washing and surface sterilizing, were cultured on pda medium(with boxwood extract).then based on availab...

Various species of common box (Buxus) are cultivated in the Arboretum of the Slovak Academy of Sciences in Mlyňany under the same soil and climatic conditions; consequently, the examination of alkaloids produced by those plants is of chemotaxonomical importance. From this locality we investigated so far alkaloids from Buxus sempervirens L.[l,2], B. microphylla SIEB, et ZUCC. var. sinica REHD. e...

Buxus wallichiana Baill, belongs to family Buxaceae. Traditionally Buxus wallichiana is used as bittertonic, diaphoretic, anti-rheumatic, vermifuge, antihelmentic, analgesic, purgative, diuretic, antiepileptic, antileprotic and in hemorrhoids. Th is paper deals with the macroscopic, microscopic and powdered studies of Buxus wallichiana wood, along with this physical constants like ash values an...

Introduction of and invasion by alien plant pathogens represents the main cause of emerging infectious diseases affecting domesticated and wild plant species worldwide. The trade in living plants is the most common pathway of introduction. Many of the alien tree pathogens recently introduced into Europe were not previously included on any quarantine lists. To help determine the potential risk o...

Objective(s) The aim of this study was to evaluate antioxidant and hair growth activities of Buxus wallichiana Baill (Buxaceae). Materials and methods Petroleum ether, chloroform, methanol and aqueous extracts of Buxus wallichiana subjected to antioxidant activity by; 2, 2-diphenyl-1-picryl hydrazyl and nitric oxide methods. Methanol extract of Buxus wallichiana at 50, 100 mg/kg, ointment of me...

Phytochemical studies on the ethanolic extract of the roots of Buxus sempervirens of Turkish origin have resulted in the isolation of two new triterpenoidal alkaloids, (+)-16a, 31-diacetylbuxadine (1), (-)-Nb-demethylcyclomikuranine (2) along with three known natural products, (-)-cyclomikuranine (3), (-)-cyclobuxophylline-K (4) and (+)-buxaquamarine (5) isolated for the first time from this sp...

Background and purpose: Alien invasive species have been described as an outstanding global problem. Hundreds of species are intentionally and unintentionally moved worldwide and and numbers of introductions to new habitats have been accelerated all over the world due to the increasing mobility of people and goods over the past decades. Numerous alien insect species, many of them introduced onl...

Three new triterpenoid alkaloids, namely buxmicrophyllines P-R (1-3), were isolated from the twigs and leaves of Buxus microphylla. Their structures were elucidated on the basis of NMR and MS spectroscopic analyses. Structurally, compounds 1-3 belong to the 9,10-cycloartane type alkaloids. In addition, compound 3 exhibited moderate cytotoxic activities in vitro against HL-60, SMMC-7221, A-549, ...
