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 increasing interest of biochemists in sulphydryl compounds has led to the necessity of finding some method for the accurate determination of these substances. That the problem is complex may be judged from the number of papers proposing new methods or modifications of old ones. The original procedure of Rosenheim and Davidsohn [1904] for the volumetric estimation of thiol acids by the use o...

BACKGROUND Tetramic acids with polyenyl substituents are an important class of compounds in medicinal chemistry. Both solid and solution phase syntheses of such molecules have been reported recently. Thiolactomycin, a clinical candidate for treatment of tuberculosis has led to further explorations in this class. We have recently developed an efficient synthesis of tetramic acids derivatives fro...

Fermented soybeans, cheonggukjang (CKJ), are considered to be more wholesome than soybeans in Korea. To select the best soybean cultivar for making functional CKJ, a comparison was made between the biological activities of four soybean cultivars in their unfermented soybean (UFS) and CKJ states. Changes in 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity, 2,2'-azino-bis (3-ethyl...

The present study was concerned with the selection of suitable surfactant for the production of alpha amylase by Bacillus subtilis GCBM-25 in 250 ml shake flask containing 50 ml of fermentation medium. Different surfactants (laundry soap, detergent powder, sulphonic acid, acyle benzene sulphonic acid, liquid soap, Tween 80, sodium silicate, bath soap, sodium tripolyphosphate, sodium lauryl ethe...

The specific purpose of this study was to evaluate the significant effects of medium-chain triglycerides (MCTs) and N-3 fatty acids on chemically induced experimental colitis induced by 2,4,6-trinitrobenzene sulphonic acid (TNBS) in rats. Male Wistar rats were fed liquid diets enriched with N-6 fatty acid (control diets), N-3 fatty acid (MCT- diets), and N-3 fatty acid and MCT (MCT+ diets) for ...

In this study, antioxidant and antimicrobial potentials of Usnea intermedia, U. filipendula, and U. fulvoreagens and their stictic and usnic acid contents were investigated. Antioxidant activity and total phenolic contents were evaluated in acetone, ethanol, and methanol extracts of these three species. Antioxidant activity was measured by ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic...
