“…This result is similar to that reported by Mohammadzadeh et al (2007). For all films analyzed, no significant differences were observed in total phenol content, and means of 27.6 mg of gallic acid/g of film were observed.…”

“…Other less abundant ions corresponding to well known flavonoids: m/z 253 (chrysin), m/z 255 (pinocembrin), m/z 269 (apigenin/galangin), m/z 271(pinobanksin), m/z 283 (caffeic acid phenethyl ester, CAPE) and m/z 313 (pinobanksin acetate), found in propolis derived from Populus resins can also be observed [35]. Iranian propolis has been shown to have antioxidant properties and to contain between 1 and 8% of flavonoids and 3-8% of phenolic compounds [36]. This composition is in agreement with the characteristic ions observed in the EASI-MS of the Iranian samples classified among group 1 samples.…”

a b s t r a c tChemical profiles of a representative set of 49 propolis ethanolic extracts collected worldwide (North and South America, Europe, Asia and Oceania) were obtained via easy ambient sonic-spray ionization mass spectrometry (EASI-MS). This simple and easily implemented fingerprinting technique analyses directly (without any pre-separation or sample manipulation) a tiny droplet of the ethanolic extract placed on a inert surface under ambient conditions. Data acquisition took about a minute per sample with no substantial sample carry-over. Extraction of propolis with ethanol by using an ultrasonic bath method gave EASI-MS data similar to the traditional maceration method, reducing total analysis time for the crude propolis resin from a week to just ca 1 h. Principal component analysis of the EASI-MS data is shown to group samples according to the plant sources of their resins, which characterizes their geographical origin.

“…The flavonoid content of flaxseeds was determined spectrophotometrically by using the aluminium nitrate method as described by Mohammadzadeh et al (2007). Briefly, 0.5 mL of flaxseeds methanolic extract was added to a test tube containing 0.1 mL of 10% aluminum nitrate, 0.1 mL of 1 M aqueous potassium acetate and 4.3 mL methanol.…”

The objective of this work was to study the nutritional and bioactive composition of commercially available flaxseeds with the aim to develop new alternatives for their use as functional and nutraceutical food ingredient. The samples of flaxseed contained 20.86% protein, 31.16% fat, 29.07% crude fiber and 3.75% ash. Essential amino acids represented 34% of total protein. The amino acids profile showed that glutamic acid was the most abundant (3.87 g 100 g -1 ), followed by arginine (1.93 g 100 g -1 ) and aspartic acid (1.52 g 100 g -1 ). Fatty acids analysis indicated that alpha-linolenic acid represents the major fatty acid (54.51% of the total fatty acids). The ratio of unsaturated to saturated fatty acids was 8.67 while the n-3/n-6 PUFA ratio was 3.2. Total phenolics showed average contents of 295.92 mg GAE 100 g -1 , of which flavonoids accounted for 25.85 mg QE 100 g -1 . The results confirmed that, in addition to being one of the richest sources of alpha-linolenic acid, flaxseed is an essential source of high quality protein, soluble fiber and potent natural antioxidants.
