ABSTRACT

Fungi can be used as a potent chemotherapeutic agent to treat various cancers. In current study acetone and methanol extracts of Terfezia claveryi, Terfezia boudieri, Terfezia olbiensis, Picoa lefebvrei, Picoa juniperi were used to assess total phenolic contents, antioxidant activity, ion-chelating impact, antimicrobial activity, the cytotoxic and protective effects. Both methanol and acetone extracts of T. boudieri had the highest FRAP and DPPH scavenging abilities. Dose-dependent increased ion-chelating impact of all tested truffles species was found. Extracts of T. boudieri, T. claveryi, and T. albiensis exhibited higher antimicrobial activities. T. claveryi and T. boudieri showed the highest protective effects against H2O2-induced genotoxicity (P < 0.05), in S. cerevisiae BY4741. The least protective effect was showed by the acetone extracts of T. olbiensis (144 ± 8); methanol extracts of P. lefebvrei (140 ± 8) and P. juniperi (140 ± 10). MCF 7 cells showed more sensitivity against to methanol extracts of T. boudieri at 10-100 µg/mL concentrations. HepG2 cells showed more sensitivity against the methanolic extracts of T. boudieri at both doses. Overall, P. lefebvrei and P. juniperi extracts had the least cytotoxic effects. The species of Terfezia exhibit significant protective effects against DNA damage and also have the potential of cytotoxicity effects.

ABSTRACT

The quality of grape cultivars not only depends on the grape cultivar but also is influenced by the molecular concepts and agro-climatic factors. For this purpose, four different grape cultivars were collected from five different locations in Siirt province (Turkey). Totally twenty different grape cultivars were investigated. In the present study, the antioxidant activity (total phenolic, flavonoid, proanthocyanidin content, DPPH and FRAP activity) in seeds were indicated and phylogenetic analysis (cpDNA;trnL-F region) of twenty native grape cultivars were investigated to construct their phylogenetic tree. According to reported data on antioxidant activity and content of phytochemicals, all cultivars exhibited different values from each other, but Rutik and Gadüv cultivars were found as significantly higher in comparison to others. According to bioinformatics analysis, twenty grape cultivars were distributed into six different major groups. Rutik and Sevkeye cultivars exhibit significant distinction from other grape cultivars. The phylogenetic analysis was also associated and supported with the results of obtained data from bioactivity. The bioactivity and phylogenetic analysis were firstly identified and quantified in these grape cultivars, however, with regard to obtained data from the current study, the grape cultivars grown in Siirt province were indicated significant and valuable results and as a result, these cultivars have to be evaluated before extinction.

ABSTRACT

Laboratory experiments were performed to determine phytotoxic potentials of white top (Lepidium draba) methanol extracts (root, stem and leaf) on germination and early growth of corn (Zea mays) and redroot pigweed (Amaranthus retroflexus). Furthermore, the effects of different methanol extracts of L. draba on the phytohormone (indole-3-acetic acid (IAA), gibberellic acid (GA), abscisic acid (ABA) and zeatin) levels of corn and redroot pigweed were investigated. It was observed that all concentrations of methanol extracts of root, stem and leaf of L. draba inhibited germination, radicle and plumule elongation when compared with the respective controls. Besides this, the degree of inhibition was increased in concert with increasing concentrations of extracts used. On the other hand, phytohormone levels changed with the application of different extract concentrations. Comparing with the control, the GA levels significantly decreased while the ABA levels increased in all the application groups. Zeatin and IAA levels showed changes depending upon the applied extracts and concentrations.
