Protective and antioxidant potential of the argan oil on induced oxidative stress in Tetrahymena pyriformis
Since reactive oxygen species (ROS) play an important role in the pathogenesis of many human diseases, attention is given to the development of safe and effective natural antioxidants. In the present study, the protective and antioxidant potential of the argan oil extracted from the fruit of Argania spinosa, an endemic tree in Morocco, was evaluated against hydrogen peroxide (H2O2) induced oxidative...

Plant-specific primers for the amplification of the nrDNA ITS region in fungus-associated Pulsatilla species
The internal transcribed spacer (ITS) region of nuclear ribosomal DNA is the most frequently used marker for distinguishing plant species. Previously published polymerase chain reaction (PCR) primers available for amplifying the ITS region from environmental plant samples provide a high degrees of success while maintaining a broad range of compatibility difficult to discriminate against fungal DNA. Thus, the...

Chemical composition and antibacterial activity of the essential oil from Eucalyptus pellita F. Muell.
The essential oil from leaves of Eucalyptus pellita F. Muell. was obtained by the hydrodistillation method and forty-three compounds in quantities higher than 0.02% were detected by gas chromatography/mass spectrometry analysis. The α-pinene (27.19% of the total amount) was the major component, followed by limonene (23.84%) and 1,8-cineole (19.01%), and considerable quantities of p-cymene,...

Anti-diabetic effects of fermented Acanthopanax senticosus extracts on rats with streptozotocin-induced type 1 diabetic mellitus
As a consequence of increased obesity prevalence, diabetes mellitus (DM) has become one of the most common diseases in humans. Acanthopanax senticosus is a species of small, woody shrub in the family Araliaceae and has been used as a medicinal plant. In a preliminary study, we found that extracts from A. senticosus fermented with Phellinus linteus (ASPL) had the most potent effects against...

Anti-oxidant properties and anti-hemolytic activity of Psidium guajava, Pandanous odorus and Rhinacanthus nasutus
The ethanolic extracts of leaves of Psidium guajava (PG), Pandanous odorus (PO),Rhinacanthus nasutus (RN) contained polyphenolic compounds in the order of PG > RN > PO. All the extracts exhibited 2,2-diphenyl-1-picryhydrazyl (DPPH) and 2,2’-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals scavenging activities. PG showed a marked antioxidant effect whereas PO and RN...

α-Glucosidase inhibitory potential of selected anti-diabetic plants used in North-Western Nigeria
α-Glucosidase inhibitory potential of selected anti-diabetic plants has been studied. The study evaluated α-glucosidase inhibition using α-glucosidase from Saccharomyces cerevisiae and p-nitrophenyl α-D-glucopyranoside as substrate. The result showed that the extract of Albizzia chevalieri leaf, Khaya senegalensis stem bark, Zizypus...

Preliminary phytochemical screening of Quercus infectoria Oliv. for treatment of skin diseases
In present work, fruits of Quercus infectoria are selected on the basis of traditional claim. Fingerprinting analysis for the said extract along with the biomarker, gallic acid was performed using high performance thin layer chromatography (HPTLC). The extract and biomarker were standardized with various instrumental techniques like Newton magnetic resonance (NMR), Fourier transform infrared (FTIR) and...
