Study of : phytochemical analysis of aqueous fruit extract and green synthesis of AgO nanoparticles.

AgO nanoparticle synthesis was carried out co-precipitation technique based on using AgNO and secondary metabolites present in the aqueous extract of fruit for the first time. The amount of measured total phenol, flavonoid content, flavone, and flavonol content, and anthocyanin were 38.46 μg eq gallic acid mg extract, 8.

Bioactive compounds analysis in ethanolic extracts of and exocarp and mesocarp.

The composition of phenolic compounds of ethanolic extract taken from mesocarp and exocarp parts of and peels cultivated in Iran have been identified. The Phenolic compounds in ethanolic extracts were quantified using HPLC-DAD. Different amounts of phenolic compounds were detected in the samples including hesperidin, -ferulic acid, catechin, sinapic acid, vanillin, chlorogenic acid and caffeic acid.

L., its antioxidant activity and polyphenolic constituents from Iran.

L belongs to the family of Umbelliferae (Apiaceae), and known also as common wild cumin. The aerial parts of were collected at the flowering stage and dried, then the methanolic extract was analyzed for polyphenol compounds identified by HPLC-DAD and antioxidant activity (DPPH(2,2-diphenyl-1-picrylhydrazyl) radical scavenging assay). It was found that the predominant phenolic constituents were chlorogenic acid, hesperidin, rosmarinic acid, hesperetin and vanillin.

Gontscharovia popovii, a new source of carvacrol, its polyphenolic constituents, essential oil analysis, total phenolic content and antioxidant activity.

The experiment was carried out using the shadow-dried aerial parts including leaves and shoots of Gontscharovia popovii collected in Fars province in order to investigate the polyphenolic compositions, antioxidant activity, total phenolic content and essential oil constituents. The result showed IC of 395.77 μg mL and total phenolic content of about 20.

The constituents of essential oil in leaves of Karaj accession of Trigonella foenum graecum.

The chemical composition of the essential oils of Karaj accession of Trigonella foenum graecum leaves was detected by hydro-distillation and analysed by gas chromatography (GC-FID) and gas chromatography-mass spectroscopy (GC-MS) apparatuses for first time. Thirty-six compounds representing 95.3% of the total components were identified.

Essential oil composition, free radical scavenging activity and polyphenolic content of Gaillonia eriantha Jaub. & Spach from Iran.

Gaillonia eriantha is a member of family Paederieae (Rubiaceae). The essential oil of G. eriantha growing wild in south of Iran was obtained by hydrodistillation and analysed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS).

An efficient and simultaneous analysis of caffeine and paracetamol in pharmaceutical formulations using TLC with a fluorescence plate reader.

A simple, rapid, and efficient method using TLC with a fluorescence plate reader has been described for simultaneous determination of caffeine and paracetamol. Determination was carried out using the fluorescence-quenching action of caffeine and paracetamol on a TLC plate with a fluorescent indicator at lambda ex = 254 nm in the linear ranges of 0.2-1.
