Abstract

F. communis and D. viscosa are perennial Mediterranean weeds that have been used for different therapeutic purposes in traditional pharmacopeia. Plant extracts were obtained from air dried D. viscosa young shoots (DvA) and F. communis aerial part (FcA) and roots (FcR) with n-hexane. The chemical compositions of the extracts were analyzed by HPLC-DAD, LC-MS (ESI) and LC-Q-TOF techniques. Two sesquiterpene lactones (inuviscolide, tomentosin) and three sesquiterpene acids (costic acid, hydroxycostic acid, ilicic acid) were identified from the D. viscosa extract, while in F. communis extracts three daucane sesquiterpenes (acetoxyferutinin, oxojaeskeanadioyl anisate, fertidin) and one coumarin (ferulenol) derivates were found. Biological activities of plant extracts were studied in in vitro experiments on the colonies and conidia of Botryotinia fuckeliana, Penicillium digitatum, P. expansum, Monilinia laxa, M. fructigena and Aspergillus spp. Extracts showed varying degree of antifungal activities on colony growth and conidia germination. The extract from FcA showed the least effect, while DvA extract had the strongest fungitoxic effects. FcRextract presented a fungitoxic effect on the colony growth, but it was not able to inhibit the conidia germination. These distinctions can be attributed to the differences in chemical composition of plant extracts.

Ethnopharmacological survey of traditional drugs sold in Israel at the end of the 20th century.

Efraim Lev, Zohar Amar (2000)

This report deals with the results of a study of present day uses of traditional medicinal materials in Israel. The survey covered selected markets in medicinal materials, belonging to various religious and ethnic communities, and also included questioning of the sellers and buyers about the healing characteristics of the various materials. The survey yielded information on many and varied medicinal materials, of which 310 are identified according to the following classifications, 264 species of plants (85.1%); 20 species of animals (6.5%); 19 kinds of minerals (6.5%); and seven materials of other or mixed origin (2.3%). Analysis of the data showed that a significant proportion of the materials were of local origin (51.5%) and some were imported from other countries. These data demonstrate that there is still a flourishing and well developed trade in these materials - a trade which is the remnant of a rich and ancient medical culture, which is disappearing from the modern world.

Antimicrobial activity of 20 plants used in folkloric medicine in the Palestinian area.

R M Yaghmour, Y R Faidi, Muslim Ali … (1998)

Ethanolic and aqueous extracts of 20 Palestinian plant species used in folk medicine were investigated for their antimicrobial activities against five bacterial species (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa) and one yeast (Candida albicans). The plants showed 90% of antimicrobial activity, with significant difference in activity between the different plants. The most antimicrobially active plants were Phagnalon rupestre and Micromeria nervosa, whereas, the least active plant was Ziziphus spina-christi. Only ten of the tested plant extracts were active against C. albicans, with the most active from M. nervosa and Inula viscosa and the least active from Ruscus aculeatus. Of all extracts the ethanolic extract of M. nervosa was the most active, whereas, the aqueous extract of Phagnalon rupestre was the most active of all aqueous extracts tested. The ethanolic extracts (70%) showed activity against both Gram positive and negative bacteria and 40% of these extracts showed anticandidal activity, whereas, 50% of the aqueous extracts showed antibacterial activity and 20% of these extracts showed anticandidal activity.
