CE Analysis of Endogenous Flavonoid Gallate Esters from Nepenthes gracilis (Nepenthaceae)

  title={CE Analysis of Endogenous Flavonoid Gallate Esters from Nepenthes gracilis (Nepenthaceae)},
  author={Da-He Fan and Hui Wang and Duo Zhi and Yong-miao Shen},
The paper described the use of capillary electrophoresis (CE) for the first time in the analysis of six structural similar flavonoid gallate esters isolated from the pitcher plant, Nepenthes gracilis (Nepenthaceae). The CE separation was achieved by optimizing the sodium borate, sodium dodecyl sulfate (SDS) and cyclodextrin (CD) concentrations. The six flavonoid gallate esters were well separated within 23 min using 10 mM sodium borate, 50 mM SDS and 50 mM γ-CD buffer at pH 9.0. It is… 
Bioactivity-guided isolation and structural characterization of the antifungal compound, plumbagin, from Nepenthes gracilis
The selectivity indices of plumbagin against all the fungi were less than 1.0, indicating that plumberagin is more toxic to mammalian than fungal cells.
New glycosides from the twigs and leaves of Rhododendron latoucheae
Abstract Six new glycosides (1−6), together with three known ones, were isolated from the twigs and leaves of Rhododendron latoucheae. Their structures were elucidated based on the spectroscopic
New Gallotannin and other Phytochemicals from Sycamore Maple (Acer pseudoplatanus) Leaves
The gallotannins were the most potent α-glucosidase inhibitors with thirteen-fold more potent activity compared with the clinical drug, acarbose, and showed the highest antioxidant activities, followed by the other phenolic sub-classes, while the sesquiterpenoids were inactive.
Screening of Panamanian Plant Extracts for Pesticidal Properties and HPLC-Based Identification of Active Compounds
A library of 600 taxonomically diverse Panamanian plant extracts was screened for fungicidal, insecticidal, and herbicidal activities, and no compound with herbicidal activity was identified.
Minireview: Recent advances in the determination of flavonoids by capillary electrophoresis
ABSTRACT Flavonoids are compounds which provide many pharmacological activities. In this paper, the literature with regard to the determination of flavonoids using capillary electrophoresis (CE)
Glucose ester enabled acylation in plant specialized metabolism
This review examines the reaction mechanism, biochemical property and evolutionary relationship of SCPL-ATs that utilize various glucose ester donors and acceptors from the same or different plant specialized metabolic pathways.
Analysis of Natural Products by Capillary Electrophoresis and Related Techniques
Despite of obvious advantages, capillary electrophoresis (CE) is often considered as an alternative analytical technique only then if more established approaches such as HPLC fail to show


Separation of some chiral flavonoids by microbial cyclosophoraoses and their sulfated derivatives in micellar electrokinetic chromatography
Neutral cyclosophoraoses (Cys) and highly sulfated cyclosophoraoses (HS‐Cys) were successfully applied as chiral selectors with SDS for the separation of some chiral flavonoids in MEKC. HS‐Cys were
Capillary electrophoresis of natural products
Capillary electrophoresis and micellar electrokinetic chromatography were used for the separation of widely different compounds from natural materials and a discussion of sample extraction and clean‐up and the advantages of using CE is presented.
Analysis of flavonoids in propolis and Ginkgo biloba by micellar electrokinetic capillary chromatography.
This micellar electrokinetic capillary chromatography method could simultaneously quantify the 10 flavonoids and be used in the quality control of functional foods containing propolis and Ginkgo biloba.
Optimization of the separation of flavonoids using solvent‐modified micellar electrokinetic chromatography
In this work the separation of eighteen flavonoids was attempted using reduced‐flow micellar elektrokinetic chromatography (RF‐MEKC) electrolytes modified by selected solvents with differing
