For the first time component composition of essential oil Rhodiola algida (Ledeb.) Fisch & C.A. Mey. family Crassulaceae, collected in places natural growth July 2020 Kazakh Altai was studied. The this species determined by gas chromatography and chromatography-mass spectrometry. method spectrometry detected 100 components, which 79 substances were identified, accounting for 82-83% total oi...

The Quaternary climate cycles forced species to repeatedly migrate across a continually changing landscape. How these shifts in distribution impacted the evolution of unrelated but ecologically associated taxa has remained elusive due to the stochastic nature of the evolutionary process and variation in species-specific biological characteristics and environmental constraints. To account for th...

Aims Rhodiola dumulosa is a perennial herb growing in a naturally fragmented habitat of high-mountain rocks. This research aims to (i) investigate the mating system characteristics and pollination biology of R. dumulosa, (ii) study the effects of ecological factors on the mating system and pollination biology of R. dumulosa and (iii) assess the relationship between its pollination and mating sy...

Objective: The present study was undertaken to evaluate the aqueous extract of K. pinnata for its protective effects on gentamicin-induced nephrotoxicity in rats. Materials and Methods: Nephrotoxicity was induced in Wistar rats by intraperitoneal administration of gentamicin 100 mg/kg/day for eight days. Effect of concurrent administration of K. pinnata leaf extract at a dose of 125 mg/kg/day g...
