In the present work, response surface methodology (RSM) based on a central composite rotatable design (CCRD), was used to determine optimum conditions for extraction of antioxidant compounds from Origanum vulgare leaves. Four process variables were evaluated at three levels (31 experimental designs): methanol (70%, 80%, and 90%), solute:solvent ratio (1:5, 1:12.5, 1:20), time (4, 10, 16 h), solute particle size (20, 65, 110 micron). Using RSM, quadratic polynomial equation obtained by...
A study was carried out to evaluate the variation of quality attributes among oils from different soybean varieties (Bovender special, Foster and F-8827).Oils were extracted using n-hexane as solvent. Results indicated that contents seed oil tested varied 15.85% 19.49%, moisture 8.4–10.2%, protein 41.67–45.64%, fiber 6.6–7.6% while ash 5.5–6.9%. The physical chemical characteristics as: color (4.2–5.3R + 40–50Y), iodine value (119–128 g I/100 oil), refractive index (1.4590–1.468), density...
Abstract Herein, we reported the imino phosphonate compounds: (4‐methoxy‐benzylidene‐amino‐phenyl‐methyl‐phosphonic acid diethyl ester ( MBPDE) , 4‐hydroxy‐benzylidene‐amino‐phenyl‐methyl‐phosphonic HBPDE ) and 4‐hydroxy‐3‐methoxy‐benzylidene‐amino‐phenyl‐methyl‐phosphonic HMBPD form chemical reaction of (α‐amino benzyl)phosphonate hydrochloride substituted benzaldehyde. These compounds were characterized by various spectroscopic techniques: FT‐IR, Mass, UV–VIS, 1H NMR 13 C NMR....
Star anise (Illicium verum Hook. fil.) is commonly utilized as a culinary and medicinal fruit most famous in indigenous systems of medicine. The present research work aims to appraise validate the potential polyphenol-rich star tea (SAT) on oxidative stress, obesity related biochemical parameters high-fat-sugar-diet (HFSD)-induced model rats. SAT was prepared using traditional method warm water. Reverse Phase High Pressure Liquid Chromatography (RP-HPLC) analysis performed for simultaneous...
Ginger (Zingiber officinale Rosc; Zingiberaceae family) is an herb commonly used as a spice and remedy for broad spectrum of diseases. The essential oil extracted from ginger effective antioxidant, anti-inflammatory, antifungal agent. present study has investigated the variations in yield chemical composition oils two cultivars (Chinese Thailand) locally available Pakistan. Two different drying pretreatments were employed to observe changes compositional ginger. fresh, oven-dried, sun-dried...
The objective of present study was to evaluate the variation in phenolic profile, β ‐carotene, flavonoid contents, antioxidant and antimicrobial properties Tagetes erecta patula ( T . ) through different vitro assays. Antioxidant activity determined 2,2‐diphenyl‐1‐picrylhydrazyl DPPH free radical scavenging inhibition linoleic acid peroxidation assays antibacterial antifungal activities studied using disc diffusion resazurin microtiter‐plate against bacterial fungal strains. Moreover, total...
The objective of the present research work was to evaluate antioxidant, antimicrobial and antimalarial activities essential oil various extracts from O. sanctum. Gas chromatography-mass spectrometry analysis identified following major compounds with their quantification as: eugenol (22.0%), β-elemene (19.2%), β-caryophyllene (19.1%), Germacrene D (5.03%). HPLC sanctum revealed that gallic acid, chlorogenic p-hydroxy benzoic caffeic vanillic p-coumeric sinapic ferulic acid were important...
