Labeled avidin-biotin (LAB) enzyme-linked immunosorbent assay (ELISA) was applied to detect Japanese encephalitis OE) antibody in swine sera. Purified laGAr-01 vaccine of lE, biotin labeled anti-swine Ig or IgM rabbit IgG conjugate and horseradish peroxidase (HRP) were employed in the assay. The f1 chain specific anti-IgM conjugate could detect only IgM antibody, but the anti-Ig conjugate could...

BACKGROUND/AIM Elevated uric acid level, an index of gout resulting from the over-activity of xanthine oxidase (XO), increases the risk of developing hypertension. However, research has shown that plant-derived inhibitors of XO and angiotensin 1-converting enzyme (ACE), two enzymes implicated in gout and hypertension, respectively, can prevent or ameliorate both diseases, without noticeable sid...

A limited number of mosses have ever been studied in regard to antioxidant activity, with only a few belonging to the European species. As part of our ongoing screening of bryophytes as natural antioxidant resources, a relevant biological activity investigation was conducted on three moss species, namely Brachythecium rutabulum (Hedw.) Schimp. (Brachytheciaceae), Calliergonella cuspidata (Hedw....


 Purpose: To investigate the anti-inflammatory effects and antioxidant activity of Oroxylum indicum (L.) Kurz fruit extract in lipopolysaccharide (LPS)-stimulated BV2 microglia.
 Methods: cells were treated with LPS for 24 h presence or absence O. extract. Then, nitric oxide (NO), reactive oxygen species (ROS) interleukin 6 (IL-16) levels measured using Griess reagent assay, CM-H2DCF...

The antioxidant properties and effect of essential oil of black pepper (Piper guineense) seeds on α -amylase, α -glucosidase (key enzymes linked to type-2 diabetes), and angiotensin-I converting enzyme (ACE) (key enzyme linked to hypertension) were assessed. The essential oil was obtained by hydrodistillation and dried with anhydrous Na2SO4, and the phenolic content, radical [1,1-diphenyl-2 pic...

In this study, n-butanol fraction (KBF) and aqueous fraction (KAF) isolated from methanol extract of Koelreuteria paniculata Laxm. leaves were evaluated for their antioxidant potential using (ABTS) 2, 2-Azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid), DPPH (2,2-diphenyl-2-picrylhydrazyl) assay, Reducing power assay and Superoxide anion radical scavenging assay. These fractions were also studi...

The chemical composition of essential oil extracted from the aerial parts Ballota saxatilis Sieber ex C.Presl Jordan has been elucidated by gas chromatography–mass spectrometry (GC-MS). Additionally, aqueous methanol (BsA), Butanol (BsB) and water (BsW) extracts were screened for their total phenol content (TPC), flavonoid (TFC), antioxidant activities using 2,2 Diphenyl-1-picrylhydrazyl (DPPH)...

The essential oils of the flowering aerial parts of two Ocimum species viz., Ocimum gratissimum and O. sanctum were analyzed by gas chromatography and gas chromatography/mass spectroscopy. The principal constituent of O. gratissimum and O. sanctum was eugenol (75.1%) and methyl eugenol (92.4%), comprising 99.3 and 98.9% of the total oils, respectively. In vitro antimicrobial activity of the ess...

In the present work we investigated, for the first time, the anti-inflammatory activity and the antioxidant properties of aqueous and ethanolic extracts, obtained from stem bark of Geoffroea decorticans (Gill. ex Hook. et Arn.) Burk. (Fabaceae). G. decorticans, commonly known as “chañar” or “chañarcillo”, is a traditional argentinean plant used as emollient, balsamic, antitussive, expectorant a...

Background. This study sought to investigate antioxidant capacity of aqueous extracts of two pepper varieties (Capsicum annuum var. accuminatum (SM) and Capsicum chinense (RO)) and their inhibitory effect on acetylcholinesterase and butyrylcholinesterase activities. Methods. The antioxidant capacity of the peppers was evaluated by the 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS...
