The minor ecdysteroids from Ajuga turkestanica.
INTRODUCTION Ajuga turkestanica is a plant used in traditional medicine for its high ecdysteroid content, including the presence of the particularly active turkesterone, which possess efficient anabolic activity. OBJECTIVES To isolate and identify minor ecdysteroids present in a semi-purified plant fraction containing ca. 70% turkesterone. MATERIAL AND METHODS Multi-step preparative HPLC (c...
متن کاملAjuga turkestanica increases Notch and Wnt signaling in aged skeletal muscle.
BACKGROUND The declining myogenic potential of aged skeletal muscle is multifactorial. Insufficient satellite cell activity is one factor in this process. Notch and Wnt signaling are involved in various biological processes including orchestrating satellite cell activity within skeletal muscle. These pathways become dysfunctional during the aging process and may contribute to the poor skeletal ...
متن کاملChemical Constituents of Ajuga parviflora
Two new antifungal withanolides, (1) and (2) have been isolated from the defatted methanolic extract of Ajuga parviflora. Their structures were established as 3/3,17/3,20-trihydroxyl-oxo-(20/?, 22/?)-witha-5,14,24-trienolide (1), 28-hydroxy-14,20-epoxy-l-oxo-(22/?)-witha2,5,24-trienolide (2) on the basis of spectroscopic data including two dimensional NMR tech niques. The pyrrolizidine alkaloi...
متن کاملChemical investigation of medicinal plant Ajuga bracteosa
In the present work, a comprehensive study was made on the analysis of chemical composition of essential oil and antibacterial activity from the leaves of Ajuga bracteosa. The essential oil was extracted by Cleavenger type apparatus and analyzed by GC-MS. The main components present in the essential oil of leaves are Limonene, α-humulene, β-Myrcene, Elemol, Camphene, βCaryophellene, α-phellendr...
متن کاملExtraction of phytoecdysones with ethanol-modified supercritical CO2
Biologically active polar substance 20-hydroxyecdysone was extracted from roots and leaves of Leuzea carthamoides with ethanol-modified dense carbon dioxide. The effect of operating conditions (pressure 20-27 MPa, temperature 40-60 oC, ethanol concentration in the solvent 4.3-7.1 wt.%, and solvent-to-feed ratio up to 100 g/g) on the extraction rate and the concentration in extract was examined....
