Validation and application by HPLC for simultaneous determination of vitexin-2″-O-glucoside, vitexin-2″-O-rhamnoside, rutin, vitexin, and hyperoside
A simple, precise, and rapid high-performance liquid chromatographic method was developed and validated for the simultaneous determination of vitexin-2″-O-glucoside, vitexin-2″-O-rhamnoside, rutin, vitexin, and hyperoside. The HPLC separation was performed using a Shim-pack VP-ODS C18 column (250 mm×4.6 mm i.d., 5 μm) with the isocratic mobile phase consisting of tetrahydrofuran/ acetonitrile/0...
متن کاملCharacterization of arsenic-resistant endophytic bacteria from hyperaccumulators Pteris vittata and Pteris multifida.
We isolated and characterized As-resistant endophytic bacteria (AEB) from two arsenic hyperaccumulators. Their plant growth promoting traits and the relation between As tolerance and transformation were evaluated. A total of 41 and 33 AEB were isolated from Pteris vittata (PV) and Pteris multifida (PM) respectively. PV AEB represented 2genera while PM AEB comprised of 12 genera, with Bacillus s...
متن کاملIsolation and identification of flavonoids components from Pteris vittata L.
BACKGROUND Pteris vittata L. is rich in flavonoids which exhibit different bioactivities. In order to investigate the flavonoids components of P. vittata L., extracts of the plant were isolated by column chromatography on silica gel and Sephadex LH-20. RESULTS Four flavonoids compounds were obtained, the structures were identified as kaempferol (1), quercetin (2), kaempferol-3-O-d-glucopyrano...
متن کاملKaempferol 3-O-rhamnoside-7-O-rhamnoside is an endogenous flavonol inhibitor of polar auxin transport in Arabidopsis shoots
Polar auxin transport (PAT) plays key roles in the regulation of plant growth and development. Flavonoids have been implicated in the inhibition of PAT. However, the active flavonoid derivative(s) involved in this process in vivo has not yet been identified. Here, we provide evidence that a specific flavonol bis-glycoside is correlated with shorter plant stature and reduced PAT. Specific flavon...
