Alkaloid accumulation in plants is activated in response to stress, is limited in distribution and specific alkaloid repertoires are variable across taxa. Rauvolfioideae (Apocynaceae, Gentianales) represents a major center of structural expansion in the monoterpenoid indole alkaloids (MIAs) yielding thousands of unique molecules including highly valuable chemotherapeutics. The paucity of genome...
In vitro induction of human embryonal carcinoma differentiation by a crude extract of Rhazya stricta
BACKGROUND Rhazya stricta Decne. is a medicinal plant that is widespread in Saudi Arabia and desert areas of the Arabian Peninsula. Its extract contains alkaloids, tannins, and flavonoids that are involved in different biological activities. The study aim was to evaluate the effects of Rhazya stricta plant extracts on the proliferation and differentiation of NTERA-2 (NT2) pluripotent embryonal ...
This study reports the high susceptibility of Propionibacterium acnes to four medicinal plants collected from western regions Saudi Arabia. Plant extracts were obtained by using methanol and acetone. The was tested agar well diffusion method. Plants interest, namely, Rhazya stricta, Azadirachta indica, Camellia sinensis Ocimum basilicum, exhibited good antibacterial activity with minimum inhibi...
The plant kingdom comprises medicinally useful plants that have provided many new drugs used to treat various diseases. In our search for bronchodilator secondary metabolites from growing in Saudi Arabia, the total extract of Rhazya stricta showed activity against carbamylcholine- (CCh) induced bronchoconstriction guinea pig tracheal muscles as an ex vivo model. fractions obtained liquid–liquid...

Rhazya stricta. an evergreen poisonous shrub is rapidly invading large areas of rangelands in Saudi Arabia. A laboratory study was conducted to investigate the effect of its dry foliage leachate on seedling growth and survival of some range plants including R. stricta its self at different stages of seedling growth. Results indicated that seedlings were more susceptible to allelopathic effects ...
Mounds originating from wind-blown sediment accumulation beneath vegetation (nebkhas) often indicate land degradation in dry areas. Thus far, most nebkha research has focused on individual plants. Here, we aimed to explore population-scale processes (up to scales of about 100 m) that might explain an observed nebkha landscape pattern. We mapped the Rhazya stricta Decne. population in a 3 ha stu...
The second industrial area located south of Riyadh City – Saudi Arabia was selected for detailed study as pollution of this area with heavy metals has accelerated dramatically during the last decades. The concentrations of eight metals (Cd, Cr, Co, Cu, Fe, Ni, Pb and Zn) in soils and different plant organs of seven native plant species (Calotropis procera , Citrullus colocynthis , Rhazya strict...
