“…As shown in Figure 2, acetone and ethanol extracts of this species exhibit significant antioxidant activity. Similar results for antioxidant activities of Salvia species have been found by others (Malencic et al, 2000;Yildirim et al, 2000;Couladis et al, 2002). Furthermore, two potent antioxidant phenolic compounds from S. plebei were also reported (Weng & Wang, 2000;Gu & Weng, 2001).…”

“…Reports have demonstrated that Hypericum species contain many phenolic compounds such as flavonoids, phoroglucinols, bisanthraquinones, and xanthones, most of which have antioxidant activity (Zheng & Wang, 2001;Couladis et al, 2002;Cakir et al, 2003;Skerget et al, 2005). Thus, the strong antioxidant potential of Hypericum species tested in the current study may be attributed to their phenolic metabolites.…”

The antimicrobial activities of chloroform, acetone, ethanol, and water extracts of 25 plants, mostly used as remedies against various diseases in Turkish traditional medicine, were tested against 10 pathogenic bacteria and one fungus (Candida albicans) using the disk diffusion method. Among the tested plant species, Ziziphora clinopodioides Lam (Labiatae), Thymus fallax Fisch et Mey. (Labiatae), and three Hypericum species [H. heterophyllum Vent., H. hyssopifolium Chaix. subsp. elongatum (Ledeb.) Woron var. elongatum, and H. scabrum L.] (Guttiferae) showed antimicrobial activity at a broader spectrum. In particular, chloroform, acetone, and ethanol extracts of Z. clinopodioides inhibited the growth of all microbial species. Minimal inhibition concentration values of Z. clinopodioides extracts were also found to be low. The antioxidant activity of the acetone, ethanol, and water extracts of 20 plants was also evaluated by lipid peroxidation inhibition and DPPH free radical scavenging methods. It was found that water, ethanol, and acetone extracts of Z. clinopodioides, T. fallax, three Hypericum species, Artemisia santonicum L. (Compositae), and Echinophora tenuifolia L. subsp. sibthorpiena (Umbelliferae) have strong antioxidant activities among the tested plant species. In general, there is a correlation between the antioxidant potential and total phenolic contents of the extracts. In light of the current study, it can be concluded that Z. clinopodioides and T. fallax may have potential use in the food industry as antioxidants and antimicrobial herbs, as well as pharmaceutical interest.

PURPOSE:To investigate if the methanolic extract of the Otostegia persica can accelerating healing process of burn wound because of its anti-inflammatory and antioxidant effects. METHODS:Forty eight male Wistar rats were randomized into three study groups of 16 rats each. Burn wounds were created on dorsal part of shaved rats using a metal rod. In group I the burn wound was left without any treatment. Group was treated with topical silver sulfadiazine pomade. In group III, ointment containing the OP extract was administered. Skin biopsies were harvested from burn area on the 3rd, 5th, 14th and 21st days after burn and examined histologically. RESULTS:Re-epithelialization in the control group and in group II was lower than in group III. Re-epithelialization in groups II and III was significantly different from that in the control group. On the 5th day of the experiment, we assessed lower inflammation in the burn area compared to control group. This means that the inflammation was suppressed by methanolic extract of OP. From day 5 to 14; the fibroblast proliferation peaked and was associated with increased collagen accumulation. It was obvious that angiogenesis improved more in the groups II and III, which facilitated re-epithelialisation. CONCLUSION:Methanolic extract of Otostegia persica exhibited significant healing activity when topically applied on rats. OP is an effective treatment for saving the burn site.

“…In addition Hollman et al (1996) reported that the herbal flavonoids contain anti-inflammatory, anti-mutagenic and anti-allergic activities. Couladis et al (2003) reported that Stachys spruneri has an anti-oxidant activity against alpha-tocoferol. Stachys annula tea has been used for centuries against cancer (Aksoy et al 1988).…”

The genotoxic and anti-genotoxic effects of Stachys petrokosmos leaf extract in human lymphocytes using microsomal fractions

The genotoxic and anti-genotoxic effects of Stachys petrokosmos leaf extracts (Sp) were investigated in human lymphocytes. The cells were treated with 1.5, 3.0 and 6.0 lL/mL concentrations of Sp leaf extracts for 24 and 48 h treatment periods in the absence and presence of metabolic activator (S9mix). In the absence of S9mix, Sp alone did not induce chromosome aberrations and formation of micronucleus while inducing the mean sister chromatid exchange at the highest concentration. In addition, Sp decreased the mutagenic effect of mitomycin-c. Sp alone showed a cytotoxic effect determined by a decrease in the proliferation index, mitotic index and nuclear division index. On the other hand a mixture of Sp and mitomycin-c resulted in a higher cytotoxic effect especially for 48 h treatment period. In the presence of S9mix, Sp was not genotoxic and cytotoxic however, it showed an anti-genotoxic effect by decreasing the effects of cyclophosphamide.
