This study aimed to compare the influence of extraction methods on the pharmaceutical and cosmetic properties of medicinal and aromatic plants (MAPs). For this purpose, the dried plant materials were extracted using advanced (microwave (MAE), ultrasonic (UAE), and homogenizer (HAE) assisted extractions) and conventional techniques (maceration, perc...

In Morocco, despite the adaptation of the prickly pear cactus (Opuntia spp) to edaphoclimatic conditions, differing from those that prevail in the countries from which it originates, this introduced species is regressing due to biotic and abiotic stresses that impact its survival. Hence, finding innovative technologies to preserve this species are...

Ziziphus spina-christi has been traditionally used as a folk medicine for a variety of therapeutic benefits. However, there is no well-documented information regarding the protective role of this plant against toxicity induced by the overdose of trace metals, including iron. This work aimed to investigate the major components, as well as the antiox...

Salt stress is one of the major environmental factors limiting cereal productivity in worldwide agriculture. Evaluating and selecting salt tolerant genotypes are an effective approach to overcome yield losses. This study aimed to characterize and compare phenotypic variability among doubled haploid (DH) barley lines and their parent under different...

The fusion of secretory vesicles with the plasma membrane depends on the assembly of v-SNAREs (VAMP2/synaptobrevin2) and t-SNAREs (SNAP25/syntaxin1) into the SNARE complex. Vesicles go through several upstream steps, referred to as docking and priming, to gain fusion competence. The vesicular protein synaptotagmin-1 (Syt-1) is the principal Ca2+ se...

Two non-aqueous titrimetric and one visible spectrophotometric methods were developed and validated for the determination of valganciclovir hydrochloride (VLGH) in pure drug and tablets. The titrimetric methods were carried out by titrating the VLGH solution in glacial acetic acid with acetous perchloric acid (HClO4) in the presence of mercuric ace...

The present study aims to design for the first time the physicochemical properties, fatty acids, tocopherols and phytosterols of cactus juice and seed oil from O. aequatorialis (O.A) and O. leucotricha (O.L) than compared with two other species widely studied [O. ficus indica (O.F.I) and O. megacantha (O.M)]. Fatty acids and phytosterols were quant...

Ethnopharmacological relevance The genus Ziziphus (Rhamnaceae) contains 58 accepted species that are extensively used by local people and medicinal practitioners in arid and semi-arid regions for the treatment of diarrhoea, dysentery, cholera, diabetic, hypertension, inflammation, intestinal spasm, liver, malaria and other diseases. Aims of this r...

Vegetables from the genus Ziziphus (Rhamnaceae) have been identified as one of the main dietary antioxidants, especially phenolic compounds. However, their chemical composition varies according to the specie or the part of the plant. Mineral composition (potassium, magnesium, calcium, sodium, iron, and zinc), polyphenolic content (Flavan-3-ol, Proa...

Tetrahymena pyriformis (protozoa) is intensely investigated as a model organism, offering numerous advantages in comprehensive and multidisciplinary studies using morphologic or molecular methods. Since DNA extraction is a vital step of any molecular experiment, here a new mixed surfactant (Sodium dodecyl sulfate (SDS) 20%/Triton X-100) was adopted...

Ziziphus spina-christi and Z. lotus are very important medicinal plants of the family Rhamnaceae. The need for accurate identification and authentication of powdered crude drug samples in the face of growing world demand for herbal products cannot be over-emphasized. The aim of this study was to determine the content of essential nutrients and phyt...

Three simple methods are described for the determination of amoxicillin (AMX) in bulk drug and dosage forms using iodate-iodide mixture reagent. These methods employed the well-known analytical reaction between iodate-iodide mixture in the presence of acid solution. The iodide oxidized by iodate to iodine in an amount equivalent to the –COOH grou...
