Abstract The classification of the legume family proposed here addresses long‐known non‐monophyly traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new uses as its framework most comprehensive phylogenetic analyses legumes to date, based on plastid matK gene sequences, and including near‐complete sampling genera (698 currently 765 genera) ca. 20% (3696) known species. region has been widely sequenced across legumes, in...
For nearly all species in the three genera of tribe Sinningieae (Gesneriaceae), Sinningia , Paliavana and Vanhouttea (mostly southeastern Brazil) plus 10 outgroups, we have sequenced six non‐coding DNA regions (i.e., plastid intergenic spacers trnT‐trnL, trnL‐trnF, trnS‐trnG, atpB‐rbcL introns trnL rpl16 genes) four nuclear plastid‐expressed glutamine synthetase gene ( ncpGS ). Separate combined analyses these data sets using maximum parsimony supported monophyly Sinningieae, but were found...
Liquid chromatography coupled to mass spectrometry (LC-MS), using atmospheric pressure chemical ionisation (APCI), was found complement data obtained from diode array detection enabling common flavonoids in Ocimum gratissimum var. be characterised at the analytical level without complete purification, or even crudely purified ethanolic extracts. Xanthomicrol, cirsimaritin, rutin, kaempferol 3-O-rutinoside and vicenin-2 were identified as major flavonoids, whereas luteolin 5-O-glucoside,...
Species of Aristolochia are associated with aristolochic acid nephropathy (AAN), a renal interstitial fibrosis and upper urinary tract cancer (UUC). Aristolochic has been reported in ten countries but its true incidence is unknown most likely underestimated. By combining an ethnobotanical phytochemical approach we provide evidence for the risk AAN occurring Bangladesh. More specifically, assess intra-specific variation analogues medicinally used indica samples from Bangladesh.Ethnobotanical...
Withania somnifera L. Dunal (Solanaceae), also known as 'ashwagandha' in Sanskrit and 'Indian ginseng', is used widely Ayurvedic medicine a nerve tonic memory enhancer, with antiaging, antistress, immunomodulatory antioxidant properties. There paucity of data on the potential neuroprotective effects W. root, traditionally used, against H(2)O(2)- Aβ((1-42))-induced cytotoxicity which are current targets for novel approaches to treat dementia, especially dementia Alzheimer's type (AD). In this...
Stenophylla coffee, an undomesticated species from Upper West Africa, is of commercial interest due to its high heat tolerance and Arabica-like flavour. To investigate the chemical basis flavour similarity, we analysed unroasted coffee bean samples using liquid chromatography–mass spectrometry (LC–MS) applied metabolomics approaches compare profiles. We report similarities between Arabica stenophylla in relative levels several key compounds linked flavour, including caffeine, trigonelline,...
Different negative ion electrospray (ES) source conditions are required to concentrate the current in [M-H](-) for malonylated and non-malonylated ginsenosides. However, both can be ionised optimally a single liquid chromatography/mass spectrometry (LC/MS) analysis by employing switchable voltages post-source optics of quadrupole trap mass spectrometer. Coupled with automatic MS/MS scanning post-acquisition neutral loss data analysis, this method provides means profiling acetylated...

(Leguminosae), Haematostaphis barteri Hook. f. (Anacardiaceae), Mitragyna inermis (Willd.) O. Kuntze (Rubiaceae) Pseudocedrela kotschyi (Schweinf.) Harms (Meliaceae), from Ghana were tested against Bacillus subtilis , Pseudomonas syringae Cladosporium herbarum using TLC direct‐autobiographic methods . Extracts...
