A metal-free 16-membered N4-donor [1 + 1] Schiff-base macrocycle was isolated as HL(Pr)·2acid, by 1 : 1 condensation of diphenylamine-2,2'-dicarboxaldehyde (1), dipropylene triamine and an excess of either acetic or formic acid, or as HL(Pr)·(tosylic acid) when just one equivalent of tosylic acid was employed. Interestingly, the acid-free synthesis employed for the 14-membered analogue HL(Et) f...

In the present study, a set of 68 P. eryngii wild strains collected from nine locations in northwest and west of Iran along with six commercial strains were studied using universal rice primers (URP). The wild strains were isolated from Ferula ovina, F. haussknechtii, Cachrys ferulacea, Kellusia odoratissima and Smyrniopsis aucheri plant species. Eleven URP primers amplified 188 polymorphic fra...

Brassavola nodosa (L.) Lindl. is a tropical epiphytic orchid showing characteristics of interest for the ornamental nursery industry, as well considered an endangered species. Problems with traditional propagation methods limit development large-scale commercial production system. The use micropropagation has been investigated this species, and liquid in vitro systems showed potential temporary...

Treatment with aqueous toluene-ethanol has been shown to induce "pore" formation in plant cell membranes. The evidence is as follows: [List: see text]While the principal experimental material was roots of Atriplex nummularia Lindl., the fact that similar results were also observed with leaves of Pisum sativum L. and with the alga Chlorella pyrenoidosa Chik. suggests that the phenomenon is gener...

The coordination chemistry of actinide(IV) ions with hydroxypyridinone ligands has been initially explored by examining the complexation of Th(IV) ion with bidentate PR-1,2-HOPO (HL1), PR-Me-3,2-HOPO (HL2), and PR-3,4-HOPO-N (HL3) ligands. The complexes Th(L)4, Th(L)4, and Th(L)4 were prepared in methanol solution from Th(acac)4 and the corresponding ligand. Single-crystal X-ray diffraction ana...

Previous reviews of plum phytochemical content and health benefits have concentrated on the European plum, Prunus domestica L. However, the potential bioactivity of red- and dark red-fleshed Japanese plums, Prunus salicina Lindl., so-called blood plums, appears to warrant a significant increase in exposure, as indicated in a recent review of the whole Prunus genus. Furthermore, Japanese plums a...
