The present study deals with the anti-hyperalgesic and anti-inflammtory effects of flavonoids (1-4) isolated from the chloroform fraction of Pistacia integerrima galls. The structure of isolated compounds was elucidated by using advance spectroscopy analysis and comparing their physical spectral data with reported one. The pretreatment of compounds (1-4) caused significant anti-hyperalgesic effects in acetic acid induced writhing test in a dose dependent manner. The compounds strongly complimented the effects in both phases of formalin test. However, the administration of naloxone did not abolish the induced antinociceptive effects and therefore suggested the absence of opioid receptor involvement. The pretreatment of flavonoids (1-4) elicited marked anti-inflammtory effects in carrageenan induced paw edema test in mice during various assessment times (1-5 h). The effects were dose dependent and maximum results were observed after 3rd h of treatments which remained significant up to 5th hour. It is concluded that the isolated flavonoids (1-4) possessed strong anti-hyperalgesic and anti-inflammtory activity and thus are strong candidates for further detail studies. © 2016.Published by Elsevier Ltd.

The current study was designed to assess the antinociceptive and skeleton muscle relaxant effect of leaves and barks of Buddleja asiatica in animal models. In acetic acid induced writhing test, pretreatment of ethanolic extract of leaves and barks evoked marked dose dependent antinociceptive effect with maximum of 70% and 67% pain relief at 300mg/kg i.p. respectively. In chimney test, the ethanolic extract of leaves and barks evoked maximum of 66.66% and 53.33% muscle relaxant effect after 90min of treatment at 300mg/kg i.p respectively. In traction test, the ethanolic extract of leaves and barks caused maximum of 60% and 73.33% muscle relaxant effect after 90min of treatment at 300mg/kg i.p respectively. In short, both leaves and barks demonstrated profound antinociceptive and skeleton muscle relaxant effects and thus the study provided natural healing agents for the treatment of said disorders.

The dimeric napthoquione 5,8,4′-trihydroxy-1′-methoxy-6, 6′-dimethyl-7,3′-binaphtyl-1,4,5′,8′-tetraone (1) was isolated from the chloroform fraction of Diospyros lotus extract. Compound 1 was screened for its inhibitory effects against four enzymes: urease, phosphodiesterase-I, carbonic anhydrase-II and α-chymotrypsin, and showed selective activity against urease enzyme with an IC50 value of 254.1 ± 3.82 μM as compared to the standard thiourea (IC50 = 21 ± 0.11 μM). Furthermore, in silico docking study was carried out to explain the molecular mechanism of compound 1 against the target receptor. © 2016 Informa UK Limited, trading as Taylor & Francis Group

A total of 177 strains of lactic acid bacteria (LAB) were isolated from early-stage Moroccan Picholine green olive fermentation, including Lactobacillus plantarum (44.63%), Lactobacillus pentosus (25.99%), Lactobacillus brevis (9.61%) and Pediococcus pentosaceus (19.77%). All the isolates were screened for their tolerance to olive leaf extract and oleuropein. Most of the isolates (85.3%) were found able to degrade oleuropein, when evaluated by either oleuropein or 5-Bromo- 4-chloro-3-indolyl β-D-glucuronide (X-Gluc) as substrates. The biodegradation capacity of the selected strains of each species was confirmed by HPLC analysis.
