Determination of Tanshinones in Danshen (Salvia miltiorrhiza) by High ‐Performance Liquid Chromatography with Fluorescence Detection after pre‐Column Derivatisation
ConclusionThe developed method is the first analytical method for tanshinones by fluorescence detection. Since the derivatisation reaction is selective for the o‐quinone structure of tanshinone, the developed method will become a suitable mean for the discovering of tanshinone type diterpenoids from herbal samples.

Phenolic Compound Diversity Explored in the Context of Photo ‐Oxidative Stress Protection
ConclusionAmong the studied compounds, anthocyanins and flavonols were the strongest singlet oxygen and hydrogen peroxide scavengers, and are thus capable of supporting defence against both photoinhibition by visible light and UV stress in leaves, while flavanols may only be effective against the latter.

A Comprehensive Characterisation of Rosemary tea Obtained from Rosmarinus officinalis L. Collected in a sub ‐Humid Area of Tunisia
ConclusionThe infusion method allows several polyphenols present in rosemary tea to be extracted, therefore it could be a reference method for rosemary's compounds extraction. Moreover, traditional Tunisian Rosmarinus officinalis tea consumption is of interest for its rich phenolic content. Copyright © 2017 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)

Infrared ‐Assisted Extraction and HPLC‐Analysis of Prunus armeniaca L. Pomace and Detoxified‐Kernel and their Antidiabetic Effects
ConclusionIn comparison to conventional‐methods, IR‐AE appeared to be an efficient and time‐conserving novel extraction method. The antidiabetic‐potentials of pomace and detoxified‐kernels of P. armeniaca were probably mediated via the attenuation of glucose‐provoked oxidative‐stress, the inhibition of alpha‐glucosidase and the marked insulin‐secretagogue effect.

Simultaneous Qualitative and Quantitative Analyses of Triterpenoids in Ilex pubescens by Ultra ‐High‐Performance Liquid Chromatography Coupled with Quadrupole Time‐of‐Flight Mass Spectrometry
ConclusionThe developed UPLC‐ESI‐QTOF‐MS method was proven to be rapid and comprehensive for simultaneous qualitative and quantitative analyses of the characteristic triterpenoids in I. pubescens. The results may provide a basis for holistic quality control and metabolic studies of I. pubescens, as well as serve as a reference for the analysis of other Ilex plants.

A Metabolomic Approach Applied to a Liquid Chromatography Coupled to High ‐Resolution Tandem Mass Spectrometry Method (HPLC‐ESI‐HRMS/MS): Towards the Comprehensive Evaluation of the Chemical Composition of Cannabis Medicinal Extracts
ConclusionsNotwithstanding the use of a standardised starting plant material, great changes are caused by different extraction procedures. The metabolomics approach is a useful tool for the evaluation of the chemical composition of cannabis extracts. Copyright © 2017 John Wiley & Sons, Ltd.
Untargeted metabolomics was successfully applied to unveil the main differences between cannabis based medicinal extracts obtained using two different solvents and four extraction time points for each solvent. A series of cannabinoids and other relevant small molecules, including alkaloids and amino acids, were identified among th...

Benefits and Limitations of DNA Barcoding and Metabarcoding in Herbal Product Authentication
ConclusionsDNA barcoding and metabarcoding have potential in the context of quality control of both well and poorly regulated supply systems. Standardisation of protocols for DNA barcoding and DNA sequence‐based identification are necessary before DNA‐based biological methods can be implemented as routine analytical approaches and approved by the competent authorities for use in regulated procedures.
