Analysis of ibuprofen and its main metabolites in roots, shoots, and seeds of cowpea (Vigna unguiculata L. Walp) using liquid chromatography-quadrupole time-of-flight mass spectrometry: uptake, metabolism, and translocation.
Analytical and bioanalytical chemistry
Dec 29, 2017
A liquid chromatography quadruple time-of-flight mass spectrometry (LC-QqTOF-MS/MS) method was developed for simultaneous quantitative analysis of ibuprofen (IBU), 1- and 2-hydroxyibuprofen (1-OH IBU and 2-OH IBU), and carboxyibuprofen (CBX IBU) whil...
Simultaneous quantitative determination of bioactive terpene indole alkaloids in ethanolic extracts of Catharanthus roseus (L.) G. Don by ultra high performance liquid chromatography-tandem mass spectrometry.
Journal of pharmaceutical and biomedical analysis
Dec 25, 2017
A rapid, sensitive and reproducible method using ultra-high-performance liquid chromatography coupled with electrospray ionization hybrid triple quadrupole-linear ion trap mass spectrometry (UHPLC-ESI-QqQ-MS/MS) in multiple reaction monitoring (MRM) ...
Antiviral activity of aconite alkaloids from Debx.
Natural product research
Dec 22, 2017
Four diterpenoid alkaloids, namely, () hypaconitine, ) songorine, () mesaconitine and () aconitine, were isolated from the ethanol root extract of Debx. The antiviral activities of these alkaloids against tobacco mosaic virus (TMV) and cucumber mosa...
An efficient soil penetration strategy for explorative robots inspired by plant root circumnutation movements.
Bioinspiration & biomimetics
Dec 22, 2017
This paper presents a comparative analysis in terms of energy required by an artificial probe to penetrate soil implementing two different strategies: a straight penetration movement and a circumnutation, which is an oscillatory movement performed by...
Synergism of prenylflavonoids from Morus alba root bark against clinical MRSA isolates.
Phytomedicine : international journal of phytotherapy and phytopharmacology
Dec 21, 2017
BACKGROUND: Clinical methicillin-resistant Staphylococcus aureus (MRSA) is a thorny problem in current anti-infective therapeutics and a challenge of new drug development. Plant prenylflavonoids possess anti-MRSA activity, but few of the prenylflavon...
Identification and characterization of the structure-activity relationships involved in UGT1A1 inhibition by anthraquinone and dianthrone constituents of Polygonum multiflorum.
Scientific reports
Dec 20, 2017
The adverse effects of Polygonum (P.) multiflorum, including abnormal bilirubin metabolism, are a serious public health issue. As uridine diphosphate (UDP)-glucuronosyltransferase 1A1 (UGT1A1) is the only enzyme responsible for bilirubin metabolism, ...
Effects and inhibition mechanism of phenazine-1-carboxamide on the mycelial morphology and ultrastructure of Rhizoctonia solani.
Pesticide biochemistry and physiology
Oct 24, 2017
The purpose of this research was to explore the effect of phenazine-1-carboxamide (PCN) on Rhizoctonia solani and to elucidate its mechanisms of action. The toxicity of PCN to R. solani was measured using a growth rate method. The results indicated t...
Root traits of European Vicia faba cultivars-Using machine learning to explore adaptations to agroclimatic conditions.
Plant, cell & environment
Oct 16, 2017
Faba bean (Vicia faba L.) is an important source of protein, but breeding for increased yield stability and stress tolerance is hampered by the scarcity of phenotyping information. Because comparisons of cultivars adapted to different agroclimatic zo...
Discrimination of plant root zone water status in greenhouse production based on phenotyping and machine learning techniques.
Scientific reports
Aug 15, 2017
Plant-based sensing on water stress can provide sensitive and direct reference for precision irrigation system in greenhouse. However, plant information acquisition, interpretation, and systematical application remain insufficient. This study develop...
