INTRODUCTION The structural annotation of target relies on high-resolution mass spectrometry (HRMS) information resulting in dubious identities in most cases. The accurate annotation of isomeric structures is still challenging to be confirmed with significant bottleneck. OBJECTIVE This study focused on the improvement of structural annotation of candidate structures via four pairs of isomeric flavanone-7-O-diglucosides and their basic flavanone aglycones commonly detected in citrus products. MET...

INTRODUCTION Dried extracts of Piper methysticum G. Forst, also known as kava, has been widely used due to its anxiolytic and sedative properties. In order to assure the quality of these extracts, it is essential to accurately quantify kavalactones, known as the active principle. OBJECTIVES To develop and validate an analytical method for the simultaneous quantification of six major kavalactones (kavain, dihydrokavain, methysticin, dihydromethysticin, yangonin and demethoxyyangonin) in kava extr...

Introduction Ardisia elliptica Thunb. (Primulaceae) is a medicinal herb that is traditionally used for the treatment of fever, diarrhoea, measles and herpes. However, there is limited information regarding the correlation of its phytoconstituents with the bioactivity. Optimisation of solvent extraction is vital for maximising retention of bioactive molecules. Objective This study investigated the metabolite variations in A. elliptica leaves and the correlation with antioxidant activities. Method...

INTRODUCTION Korean mugwort has been used as a traditional medicine. Specifically, air-dried Artemisia princeps Pamp. cv. ssajuari (ssajuari-ssuk; Korean mugwort) has been used as moxa in moxibustion therapy. Thus, the evaluation of high quality ssajuari-ssuk containing herbal volatiles is of great interest in clinical therapy and the food industry. OBJECTIVE The aim of this study is to determine whether fast gas chromatography with uncoated surface acoustic wave (fast GC/SAW) sensor can be a us...

Introduction Medicinal plants have been used in healthcare since time immemorial, as have their therapeutic activities and the production of plant-based medicines. Objectives This study aims to use gene-targeted molecular markers for genetic diversity analysis of 16 medicinal plants. Besides, phytochemical analysis antibacterial and antifungal activities of some medicinal plant extracts commonly used in Egypt are compared to major compounds. Methods DNA-based classification of 16 medicinal speci...

INTRODUCTION Two species of oak are dominant in French forests: pedunculate oak (Quercus robur L.) and sessile oak (Quercus petraea Liebl.). Differentiating oak species is difficult, since features such as morphological characters, geographical origin and grain are not always relevant. Even if the former is generally richer in tannin compounds while the latter is often richer in aromatic compounds, the intra-species variability is high. The characterisation of the oak species remains a suitable ...

Introduction Hypericum perforatum L., Hypericaceae (St John's wort) is a highly familiar plant in the medicinal community which recently showed good antiviral activities including against some types of coronavirus. Objective Establishing the kinetics of isothermal extraction of total hypericin (TH) from the pre-extracted flowers of H. perforatum flowers. Methods The solvent extraction of TH from the remaining solid residue after the pre-extraction procedure was performed providing isothermal con...

INTRODUCTION Moringa oleifera Lam. is widely cultivated and applied in tropical and subtropical areas. Numerous studies have been focused on the antioxidant capacity of M. oleifera leaves, but its correlated bioactive phytochemicals remain elusive. OBJECTIVE In order to search for the corresponding chemical compounds from M. oleifera leaves responsible for their antioxidant activity, the correlations between phytochemical fingerprints of 15 batches of M. oleifera leaves and their antioxidant act...

INTRODUCTION The roots of Polygonum multiflorum (PM) serve as a classical traditional Chinese medicine (TCM), which has multiple biological activities. However, many cases of hepatotoxicity in PM have been reported in recent years. Processing PM with black beans decoction is one of the typical processing methods to reduce the hepatotoxicity of PM since ancient times. OBJECTIVES To find potential effective constituents, as well as the optimal variety and origin of black beans for the processing o...

Introduction The tomato plant, Solanum lycopersicum L. (Solanaceae), is one of the most widely consumed vegetables in the world and plays an important role in human diet. Tomato cultivars are hosts for diverse types of pests, implying diverse chemical defence strategies. Glycoalkaloids are the main specialised metabolites produced by tomato leaves and fruits to protect against pests. However, the roots have received little attention, leading to limited knowledge about their phytochemical content...
