Antidesma bunius is an edible berry fruit with many benefits, such as natural antimicrobials, anticancer, dyes, etc. However, data on chemical content in the still limited. The purpose of this research to identify volatile compounds fruit. We extracted and analyzed A. fruit’s using GC-MS HPLC–DAD-ESI-MS methods. Forty-nine representing 99.91% total chromatogram’s relative peak area were detecte...

Flavonoid fraction composition of Larix dahurica Turcz. knotwood was studied with HPLC-DAD/ESI-MS/MS. Dihydroquercetin, aromadendrin, dihydroisorhamnetin, eriodictyol and quercetin were revealed as its components.

weichang’an (wca) pill, a traditional chinese patent medicine consisting of ten chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. in this study, twelve bioactive constituents in the methanol extract of wca were accurately identified since ms/ms fragmentation behavior of the references and the standards by using hplc-dad-esi-ms...

FeiYangchangweiyan capsule (FY capsule), a traditional Chinese medicinal preparation consisting of three medicinal herbs, has been used to treat bacterial dysentery, acute, and chronic gastroenteritis for several decades. In this study, a novel, convenient, accurate, and valid method was developed by using high-performance liquid chromatography (HPLC) coupled with diode array detection...

High-performance liquid chromatography-diode array detector (HPLC-DAD) coupled with electronspray mass spectrometry (ESI-MS) was used to detect the flavonoid profile in lemon juices obtained from the main Sicilian cultivars (Femminello comune, Monachello, and Interdonato). Significant amounts of an unusual constituent were found in the lemon juice of the above-mentioned cultivars together with ...

Twenty three samples of 18 Portuguese olive leaf cultivars were analysed by a reversed-phase HPLC/DAD procedure and eight flavonoidic compounds were identified and quantified (luteolin 7,4'-O-diglucoside, luteolin 7-O-glucoside, rutin, apigenin 7-O-rutinoside, luteolin 4'-O-glucoside, luteolin, apigenin and diosmetin). Luteolin 7,4'-O-diglucoside and luteolin 4'-O-glucoside were identified by H...

ABSTRACT: This research assessed the phenolic composition of Jussara pulp from Brazilian states Minas Gerais (MG) and Espírito Santo (ES) using HPLC-DAD-MS/MS. Seventeen anthocyanins were detected in fruits, derived cyanidin, pelargonidin peonidin. Among non-anthocyanic compounds, flavonols (kaempferol, quercetin isorhamnetin derivatives), flavan-3-ols (catechin, epicatechin, B-type procyanidin...

BACKGROUND Bioactive activities of adzuki bean have been widely reported, however, the phytochemical information of adzuki bean is incomplete. The aim of this study was to characterize and quantify flavonoids and saponins in adzuki bean. High performance liquid chromatography with diode array detection and electro spray ionization-tandem multi-stage mass spectrometry (HPLC-DAD-ESI-MSn) were app...
