The names of all mosses published up to the end of August 2011 in the countries of the Mediterranean basin, the Macaronesian Islands and Bulgaria are compiled in an annotated checklist. The list comprises accepted names and synonyms, and provides explanatory annotations for ambiguous and disputed names. Literature references supporting the reports in each individual area are given only for taxa reported once or in a single locality. A total of 1168 accepted species and 81 infraspecific taxa are reported from the whole area. Mosses / distribution / nomenclature / checklist / Mediterranean

The aim of this study was to estimate the total amount of phenolic compounds of olive trees leaves (Olea europaea L.) as a biomarker for the assessment of heavy metals (HMs) air pollution (Pb, Cu and Mn) in Baniyas area. Olive trees were selected as the predominant species in the study area. Samples were collected from 6 locations at different distances from the vicinity of Baniyas refinery (0.1, 0.5, 2, 4, 6, 10) Km. The control was taken from an area about 20 km from the refinery to the north-east (Al-Qardaha rural). The concentration of total phenolic compounds (TPC) during the summer was (45.6 -70.85) mg GAE/g dw, and during winter (35.6 -52.9) mg GAE/g dw. The concentrations of the studied HMs (Pb, Cu and Mn) in unwashed leaves during summer were (0.879 -2.170) ppm, (0.75 -5.21) ppm and (54.38 -8.78) ppm respectively, whilst during the winter concentrations were (0.479 -1.023) ppm, (1.54 -7.29) ppm and (53.79 -7.58) ppm respectively. The results showed significant differences in the concentration of total phenolic compounds and HMs (Pb, Cu and Mn) between sites (ANOVA), significant differences in concentrations of both total phenols and HMs (Pb and Cu) between summer and winter at all sites (t-test, p < 0.05). TPC, Pb and Mn were higher in summer in all sites than in winter. Levels of Cu were significantly higher in winter than in summer at all sites (t-test, p < 0.05). The results showed a negative correlation (t-test, p < 0.05) between the concentration of

Macaranga is a large genus belongs to Euphorbiaceae family which commonly distributed in the tropical region of Africa, South-East Asia, China, and India. The plant of this genus contain flavonoids and stilbenes bearing various terpenyl groups including prenyl, geranyl and farnesyl groups. The leaves of M. hypoleuca were collected from reserved forest UiTM Jengka Pahang, Malaysia, and the dried powdered leaves were macerated in methanol at room temperature. The crude methanol extract was subjected to liquid-liquid partition using n-hexane and ethyl acetate to obtain hexane, ethyl acetate and aqueous fractions. The ethyl acetate fraction was semi purified using vacuum liquid chromatography (VLC) to give nine major fractions (MHL1-MHL9). Fraction MHL3 was further purified by column chromatography (CC) and preparative thin layer chromatography (p-TLC) to give two pure compounds, 8-prenylnaringenin (1) and sakuranetin (5,4’-dihydroxy-7-methoxyflavanone) (3). Meanwhile, fraction MHL6 was purified using column chromatography (CC) and p-TLC to yield another two pure compounds, 6-(3-hydroxy-3-methyl)naringenin (2) and 7-O-methyleriodictyol (4). The chemical structure of these isolated compounds were determined based on their 1D and 2D NMR, UV, and IR data. From this study, four flavanones were isolated from the leaves of M. hypoleuca.
