Verbascoside (VB) is a bioactive polyphenol from olive oil mill wastewater with known antioxidant activity. Oxidative stress is an emerging problem in assisted reproductive technology (ART). Juvenile ART is a promising topic because, in farm animals, it reduces the generation gap and, in human reproductive medicine, it helps to overcome premature ovarian failure. The aim of this study was to te...

To understand the resistance of the olive tree to the leaf-spot disease caused by Spilocaea oleagina, the constitutive and postinfectional synthesis phenolic compounds of the leaves were analyzed by HPLC in 110 genotypes F1 (susceptible cultivar “Picholine marocaine” x resistant cultivar “Picholine du Languedoc”) presenting of the differential behaviours to this disease (highly resistant, resis...

There are 34 Phlomis L. species (Labiatae) growing in Turkey. Some Phlomis species are used as tonics and stimulants in Anatolia . During our systematic phytochemical investigations of Phlomis species we have studied P. linearis Boiss. & Bal.3−6, Phlomis armeniaca Willd., Phlomis pungens Willd. var. pungens 8−10, Phlomis pungens Willd. var. hirta Velen, Phlomis bourgaei Boiss., and Phlomis long...

Quantitative determination of multiple effective components in a given plant usually requires a very large amount of authentic natural products. In this study, we proposed a rapid and non-destructive method for the simultaneous determination of echinacoside, verbascoside, mannitol, sucrose, glucose and fructose in Cistanche tubulosa by near infrared spectroscopy (NIRS). Near infrared diffuse re...

Introduction – Scutellaria lateriflora, commonly known as skullcap, is used as an ingredient in numerous herbal products. Unfortunately, it has occasionally been adulterated with Teucrium canadense or T. chamaedrys, commonly known as germander, which contains potentially hepatotoxic diterpenes. Chromatographic profiles of the phenolic components provide a means of distinguishing between these p...

Acteoside (verbascoside) is extensively distributed in Abeliophyllum distichum and has antimicrobial and anti-inflammatory properties. Thymic stromal lymphopoietin (TSLP) has a pivotal function in the pathogeneses of inflammatory diseases through increasing the mast cell proliferation via the activation of murine double minute 2 (MDM2). Here, we investigate whether acteoside attenuates the MDM2...

characterized by irreversible, progressive loss of memory followed by complete dementia. Cognitive impairment in AD is caused mainly by death of cholinergic neurons in basal forebrain area, though other neurotransmitter systems could well be involved. A deficit of acetylcholine (ACh) in an AD brain is well known. At the same time, extent of dementia correlates well with the extent of neuronal d...

The chemical composition of finished table olive products is influenced by the olive variety and the processing method used to debitter or cure table olives. Herein, a rapid ultrahigh-pressure liquid chromatography triple-quadrupole tandem mass spectrometry method, using dynamic multiple reaction monitoring, was developed for the quantitation of 12 predominant phenolic and secoiridoid compounds...
