Screening of Plant Extracts for Antioxidant Activity: a Comparative Study on Three Testing Methods
Tập 13 Số 1 - Trang 8-17 - 2002
AbstractThree methods widely employed in the evaluation of antioxidant activity,
namely 2,2′‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging method, static
headspace gas chromatography (HS‐GC) and β‐carotene bleaching test (BCBT), have
been compared with regard to their application in the screening of plant
extracts. The strengths and limitations of each method have been illustrated by
testing...
A bioautographic agar overlay method for the detection of antifungal compounds from higher plants
Tập 2 Số 5 - Trang 199-203 - 1991
AbstractA simple bioautographic agar overlay assay using Candida albicans as the
indicator organism for the detection and activity‐guided fractionation of
antifungal compounds by thin layer chromatography has been developed. Inhibition
of fungal growth was assessed by the detection of dehydrogenase activity with
thiazolyl blue (methylthiazolyltetrazolium chloride; MTT). A series of
clinically used...
An efficient microwave‐assisted extraction process of stevioside and rebaudioside‐A from Stevia rebaudiana (Bertoni)
Tập 20 Số 3 - Trang 240-245 - 2009
AbstractIntroductionStevioside and rebaudioside‐A are major low‐calorie
diterpene steviol glycosides in the leaves of Stevia rebaudiana. They are widely
used as natural sweeteners for diabetic patients, but the long extraction
procedures required and the optimisation of product yield present challenging
problems.ObjectiveTo develop a rapid and effective methodology for the
extraction of stevioside...
Qualitative and Quantitative Analyses of Flavonoids in Spirodela polyrrhiza by High‐performance Liquid Chromatography Coupled with Mass Spectrometry
Tập 22 Số 6 - Trang 475-483 - 2011
ABSTRACTIntroductionSpirodela polyrrhiza (L.) Schleid. is a traditional Chinese
herbal medicine for the treatment of influenza. Despite its wide use in Chinese
medicine, no report on quality control of this herb is available so
far.ObjectiveTo establish qualitative and quantitative analytical methods by
high‐performance liquid chromatography (HPLC) coupled with mass spectrometry
(MS) for the quali...
Analysis of secondary metabolites from Lichen by high performance liquid chromatography with a photodiode array detector
Tập 5 Số 4 - Trang 197-205 - 1994
AbstractSecondary metabolites from Lichen, mainly phenolic compounds, have been
analysed and identified using high performance liquid chromatography with a
photodiode array detector. Components of lichen thalli were detected by
characteristic ultraviolet spectra and relative retention times. Some new minor
components have been found in several lichens.
Analysis of Rhizoma Polygoni Cuspidati by HPLC and HPLC‐ESI/MS
Tập 18 Số 5 - Trang 387-392 - 2007
AbstractAn HPLC method with photodiode array detection (PAD) and ESI/MS
detection was developed for the qualitative and quantitative analysis of the
major chemical constituents of the dried rhizome of Polygonum cuspidatum Sieb.
et Zucc. (Rhizoma Polygoni Cuspidati; Chinese name Hu‐Zhang). Based on the
chromatographic separation on an Altima C18 column using 0.5% aqueous acetic
acid and acetonitril...
Analysis of Eleven Phenolic Compounds Including Novel p‐Coumaroyl Derivatives in Lettuce (Lactuca sativa L.) by Ultra‐high‐performance Liquid Chromatography with Photodiode Array and Mass Spectrometry Detection
Tập 22 Số 6 - Trang 555-563 - 2011
ABSTRACTIntroductionLettuce is a widely consumed vegetable and a good source of
phenolic compounds. Several factors (genetic, agronomical and environmental) can
influence the lettuce composition; their effects are not completely defined and
more studies are needed on this topic.ObjectiveTo develop an improved
ultra‐high‐performance liquid chromatography (UHPLC) method to quantify the main
target i...
Determination of Endogenous Brassinosteroids in Plant Tissues Using Solid‐phase Extraction with Double Layered Cartridge Followed by High‐performance Liquid Chromatography–Tandem Mass Spectrometry
Tập 24 Số 4 - Trang 386-394 - 2013
ABSTRACTIntroductionBrassinosteroids (BRs) are a group of important
phytohormones that play vital roles in plant growth, development and a series of
physiological phenomena. In order to understand biosynthesis, degradation and
metabolic pathways of BRs, a reliable analytical method of BRs with effective
sample pre‐treatment process is favourable.ObjectiveThe development of a quick
and effective me...
Flavonoid Constituents of Phlomis (Lamiaceae) Species Using Liquid Chromatography Mass Spectrometry
Tập 29 Số 2 - Trang 180-195 - 2018
AbstractIntroductionPhlomis is one of the medicinal genera of Lamiaceae. This
genus has unique medicinal properties. Consequently, appropriate methods need to
be described for the identification of the chemical compounds.ObjectiveA liquid
chromatography tandem mass spectrometry (LC–MS/MS) technique on a triple
quadrupole mass spectrometer (TQMS) was used for separation and identification
of leaf f...
Analysis of phytochemical variations in dioecious Tinospora cordifolia stems using HPLC/QTOF MS/MS and UPLC/QqQLIT‐MS/MS
Tập 27 Số 2 - Trang 92-99 - 2016
AbstractIntroductionThe stem of dioecious Tinospora cordifolia (Menispermaceae)
is a commonly used traditional Ayurvedic medicine in India having several
therapeutic properties.ObjectiveTo develop and validate LC‐MS methods for the
identification and simultaneous quantitation of various secondary metabolites
and to study metabolomic variations in the stem of male and female
plants.MethodsEthanolic...
