Phenolic compounds (polyphenols) are common plant secondary metabolites playing different roles in plants, and some of these vegetables and correlated fruits-figs, grapes, pomegranates, olives, date palms, etc.-contain remarkable and diversified amounts of these substances. In addition, polyphenols are reported to show positive effects for human health, because of their antioxidant behavior. Figs are an excellent source of polyphenols with highest concentrations of proanthocyanidins. Actually, figs contain higher amounts of polyphenols than red wine and tea.
Antioxidant activity of several flavonoids (a group of polyphenols) in figs is higher than that of, vitamin C, glutathione, or vitamin E. Pomegranates contain very high levels of polyphenols as compared to other fruits and vegetables. It is used in folklore medicine for the treatment of various diseases, such as hepatic damage, snakebite, ulcer, etc.
The health-positive potential of pomegranate fruit has been mainly attributed to ellagitannins, the predominant class of phenolics in pomegoxidation.
The chief phenolic compound found in fresh olive is the bitter secoiridoid oleuropein..
Processing of table olive decreases levels of oleuropein with correlated increases in the hydrolysis of hydroxytyrosol and tyrosol. find more Many of the health benefits reported for olives are thought to be associated with the levels of hydroxytyrosol. Date palm represents a staple food in most of the Arabian countries and is commonly consumed in several parts of the world.
Numerous researches revealed the antibacterial, anti-hyperlipidemic, hepatoprotective, antimutagenic, and nephroprotective activity of date fruits, with reported anticancer and anti-fungal features.

Bacterial enumeration data are typically log transformed to realize a more normal distribution and stabilize the variance. Unfortunately, statistical results from log transformed data are often misinterpreted as data within the arithmetic domain.
To explore the implication of slope and intercept from an unweighted linear regression and compare it to the results of the regression of log transformed data.
Mathematical formulae inferencing explained using real dataset.
For y=Ax+B+ε, where y is the recovery (CFU/g) and x is the target concentration (CFU/g) with error ε homogeneous across x. When B=0, slope A estimates percent recovery R. In the regression of log transformed data, logy=αlogx+β+εz (equivalent to equation y=Axα·ω), it is the intercept β=logyx=logA that estimates the percent recovery in logarithm when slope α=1, which means that R doesn't vary over x. Error term ω is multiplicative to x, while εz or log(ω) is additive to log(x). Whether the data should be transformed or not is not a choice, but a decision based on the distribution of the data. Significant difference was not found between the five models (the linear regression of log transformed data, three generalized linear models and a nonlinear model) regarding their predicted percent recovery when applied to our data. An acceptable regression model should result in approximately the best normal distribution of residuals.
Statistical procedures making use of log transformed data should be studied separately and documented as such, not collectively reported and interpreted with results studied in arithmetic domain.
The way to interpret statistical results developed from arithmetic domain does not apply to that of the log transformed data.

The presence of phenolic acids in edible products for human consumption is considered in relation to the production of odorant substances, with a variety of different aromas.
Phenolic substances anthocyanidins, anthocyanins, flavanols, flavones and isoflavones, flavones, flavonols, etc. - are extremely interesting as flavor additives, anti-aging or maturing agents, and color and aroma enhancers.
The connection between flavoring properties on one hand and the presence of phenolic compounds on the other can be discussed in terms of food acceptance by consumers, especially with relation to the "Mediterranean Diet" lifestyle.
The health perspectives of these and other food products related to Mediterranean Diet should be evaluated in the geographical ambit of the Mediterranean Basin, including several particular food and vegetable preparations - herbs and medicinal plants - of the Middle East.
The aim of this paper is to give a presentation on these specialties in relation to Jordan.
Medicinal herbs have interesting health properties against digestive problems, parasitic worms, liver diseases, diabetes, skin problems, nervous, cardiocirculatory, and respiratory diseases.

Lutein is gaining attention as a strong antioxidant contained in foods. It accumulates in the human blood and retina, and is considered to play an important role in the body, especially in the eyes.
A method to determine the lutein content of raw spinach (Spinacia oleracea L.) was developed with the aim of its enactment as a Japanese agricultural standard (JAS) measurement method for components beneficial to human health.
An interlaboratory study was conducted to evaluate an analytical method for the determination of lutein in spinach. The detection limit and quantification limit of lutein for this method were 0.2 and 0.7 mg/kg, respectively. Twelve participating laboratories independently analyzed test samples (five pairs of blind duplicates) using high-performance liquid chromatography (HPLC).
After removal of a few outliers, the repeatability relative standard deviation (RSDr), reproducibility (RSDR), and predicted RSDR of the evaluated method were 3.4-7.5, 4.6-13, and 7.5-8.5%, respectively, in a concentration range from 64.
