Hexane Extracts

Spices are a part of the plants used for many purposes as preservatives and as colorants in foods or as medicinal intention. Main aim of the present research was to estimate the potential antimicrobial activity of some spices from Apiaceae family such as Amni visnaga (Diş otu, Hıltan), Anethum graveolens (Dereotu), Apium graveolens (Kereviz), Coriandrum sativum (Kişniş), Cuminum cyminum (Kimyon), Daucus carota (Havuç), Foeniculum vulgare (Rezene), Petroselinum sativum (Maydanoz), Pimpinella anisum (Anason). Thus, the fruits of the plants are used in the experiments. The fruits have been extracted by n-hexane, and all extracts have been subjected to TLC (Thin Layer Chromatography). The n-hexane extracts were screened for their potential in vitro antibacterial activity against Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 13883, Pseudomonas aeruginosa ATCC 27853 and antifungal activity against Candida albicans ATCC 10231 by microbroth dilution method. The hexane extracts of the fruits of Coriandrum sativum, Anethum graveolens, Daucus carota, and Pimpinella anisum did not show antimicrobial activity against tested microorganisms. Except these, the other extracts having MIC values of 2.5-5-10 mg/mL exhibited antimicrobial effect against some tested microorganisms. These results demonstrate that the extracts which have an antimicrobial effect can probably play a role as an antimicrobial agent owing to their nonpolar components which are accumulated to the n-hexane extracts.

Biological Actions

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.

Nine strains of yeasts capable of decomposing oil were isolated in order to directly treat wastewater from oil manufacturing plants with no pretreatment. The oil decomposing ability of these yeast strains was evaluated in terms of lipase activity and β-oxidation activity. Since the mixture of the isolated yeasts was superior to any single strain in the oil removal rate, a pilot plant utilizing the mixed strains was operated at the soybean oil factory. Following a one year pilot plant operation, it was found that 10,000 mgℓ−1 of hexane extracts in the raw wastewater could be reduced by yeast treatment to a concentration of about 100 mgℓ−1. This concentration was further treated by the activated sludge process to 2 mgℓ−1. The dominant yeasts in the pilot plant were found to form mycelial or pseudomycelial pellets and have low fermenting ability.
