BACKGROUND The discovery of the only animal pigment, bilirubin, in the plant Strelitzia nicolai has triggered a vast number of questions regarding bilirubin's formation and its role in the human body. Recent studies have confirmed that bilirubin at certain levels have many medical benefits. Various case studies have revealed that bilirubin is a potent antioxidant. Cervical cancer is one of Sout...

The first examples of Cu-catalyzed γ-selective allylic alkenylation using organozinc reagents are reported. (E)-Alkenylzinc iodides were prepared by Fe-catalyzed reductive coupling of terminal arylalkynes with alkyl iodides. In the presence of a copper catalyst, these reagents reacted with allylic bromides derived from Morita-Baylis-Hillman alcohols to give 1,4-dienes in high yields. The reacti...

Fruits of Trichilia cuneata (Meliaceae), a common tree in dtiet fotests of Central America, are eaten by a numbet of birds. The fruits are 10 to 12 mm in diameter, covered by a yellowish-brown, capsular exocarp, and contain three to six seeds distributed among three locules. Each seed is covered by an orangish-red aril that averages 59.7 percent lipid and 15.1 petcent protein, which makes this ...

Endosperm and embryo tissues from the seeds of Euonymus alatus (Burning Bush) accumulate high levels of 3-acetyl-1,2-diacyl-sn-glycerols (acTAGs) as their major storage lipids. In contrast, the aril tissue surrounding the seed produces long-chain triacylglycerols (lcTAGs) typical of most other organisms. The presence of the sn-3 acetyl group imparts acTAGs with different physical and chemical p...

aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. this study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘malase saveh’ pomegranates. the results indicated that concentrations of cu in the aril and k, mg, and mn i...

a simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid n-methyl-2-pyrrolidonum hydrosulfate ([h-nmp]hso4). the diazonium salts that are formed by this ionic liquid are stable at room temperature and react rapidly wi...

introduction iran is a frontier of pomegranate fruit production in the world (with almost 40 % of the world`s production). however due to traditional processing operations is not ranked as the largest pomegranate exporter. saveh, neyriz and ferdows are the top pomegranate producing cities in iran. pomegranate is consumed as a fresh fruit as well as processed product as food additive, paste, syr...
