Haplophyllum Myrtifolium

Introduction: In the classic treatment of Trichomonas vaginalis infection, although metronidazole has been used since the 1960s, there has been an increase in MTZ-resistant T. vaginalis strains and failure in the treatment of trichomoniasis causes serious concerns. Therefore, the present study aimed to investigate the in vitro antitrichomonal activities of extracts (ethanol and total alkaloid) and pure compounds (chrysosplenetin, dictamnine, gamma-Fagarine, skimmianine) of H. myrtifolium against T. vaginalis. Methodology: H. myrtifolium was collected from the town of Honaz in Denizli, located in the Aegean region of Turkey, and preparation of extracts and isolation and structure elucidation of pure compounds were performed. Later, different concentrations of extracts and pure compounds were incubated with T. vaginalis trophozoites isolated from Turkey, which are known to be sensitive to metronidazole. Results: It was found that ethanol extract caused a more effective lysis on T. vaginalis trophozoites compared with total alkaloid extract (P < 0.05). No compounds except for furoquinoline alkaloid skimmianine prepared above 37.5 µg/mL were found to have any inhibitory effect on T. vaginalis trophozoites. Conclusion: The ethanol extract of H. myrtifolium and skimmianine can be considered as potential candidates for antitrichomonal drug development.

  Objective: The objective of this study is to determine the minimum inhibitory concentration (MIC) of red betel leaf ethanol extract against Trichomonas vaginalis trophozoites.Materials and Methods: The samples of red piper betel leaf were extracted with 70% ethanol using a maceration method. The phytochemical screening of ethanol extract was performed using the standard procedures. Isolation of T. vaginalis trophozoites from vaginal secretions was conducted using swab method, then suspending it into a saline solution sterile and followed by observing trophozoites motility using a microscope. While the anti-leucorrhea activity test and determination of MIC extract was done using macrodillution method. The inhibitory effect of each extract concentration to trichomonas trophozoites’ morphology was observed under a microscope using staining techniques by adding Giemsa dyes.Results: The extract of red piper betel leaves contains several secondary metabolites such as alkaloids, flavonoids, polyphenols, quinones, and saponins. Of the six vaginal secretions, four positive trichomoniasis secretions were obtained. The results of anti-leucorrhea activity of red piper betel ethanol extract showed that the number of inactive trophozoites was proportional to the increasing of extract concentration. The inactive trophozoites were characterized by the absence of its motility under microscope observation. The MIC value of red piper betel extract of T. vaginalis trophozoites was 5% w/v.Conclusion: It can be concluded that the ethanol extract of red piper betel leaves could be contribute as a natural and safe anti-leucorrhea candidate for in vivo study on trichomoniasis in the future.

Cryptococcosis is a worldwide disease caused by the etiological agent Cryptococcus neoformans. It affects mainly immunocompromised humans. It is relatively rare in animals only affecting those that have received prolonged antibiotic therapy. The propolis is a resin that can present several biological properties, including antibacterial, antifungal and antiviral activities. The standard strain C. neoformans ATTC 90112 was used to the antifungal evaluation. The tests were realized with propolis ethanol extract (PEE) G12 in concentrations from 0.1 to 1.6 mg mL-1. The evaluation of MIC and MFC were done according to DUARTE (2002)5. The inhibitory effect of PEE G12 on the fungal growing was seen at the concentration of 0.2 mg mL-1 and 1.6 mg mL-1 was considered a fungicidal one.

Rosmarinus officinalis, which belongs to the Lamiaceaefamily, is a species of medicinal flora with therapeutic properties. In order to exploit the benefits of these properties, a mouthwash formulation was developed, with careful selection of raw materials to meet pharmacotechnical requirements. Extracts of the plant were incorporated into a mouthwash, which was shown to have inhibitory action in vitro against the micro-organisms commonly found in periodontics. Controls for assessing the quality of the drugs were carried out, quantifying phenols and flavonoids as chemical markers. Mouthwash solutions were formulated containing 0.1, 5 and 10% ethanol extract of R. officinalis; and 0.05, 5 and 10% of the hexane fraction of R. officinalis. In order to evaluate synergism, ethanol extract and hexane fraction were also added to formulations containing 0.05% sodium fluoride and 0.12% chlorhexidine digluconate. These formulations were assessed for inhibitory effect against the specific microorganisms involved in the process of bacterial plaque formation, S. mutans(ATCC25175) and C. albicans(ATCC 10231), frequently found in cases of oral infections. The agar diffusion method was used to evaluate the inhibitory activity of extracts and formulations. All mouthwash solutions displayed inhibitory activity having higher sensitivity to S. mutansfor the 5% ethanol extract+0.05% sodium fluoride, and greater sensitivity to C. albicansfor the 10% hexane fraction. Results were characterized by the appearance of a growth inhibition halo, justifying the utilization and association of extracts of R. officinalis.

Abstract Human trichomoniasis, caused by the pathogenic parasitic protozoan Trichomonas vaginalis, is the most common non-viral sexually transmitted disease that contributes to reproductive morbidity in affected women and possibly to prostate cancer in men. Tritrichomonas foetus strains cause the disease trichomoniasis in farm animals (cattle, bulls, pigs) and diarrhea in domestic animals (cats and dogs). Because some T. vaginalis strains have become resistant to the widely used drug metronidazole, there is a need to develop alternative treatments, based on safe natural products that have the potential to replace and/or enhance the activity of lower doses of metronidazole. To help meet this need, this overview collates and interprets worldwide reported studies on the efficacy of structurally different classes of food, marine, and medicinal plant extracts and some of their bioactive pure compounds against T. vaginalis and T. foetus in vitro and in infected mice and women. Active food extracts include potato peels and their glycoalkaloids α-chaconine and α-solanine, caffeic and chlorogenic acids, and quercetin; the tomato glycoalkaloid α-tomatine; theaflavin-rich black tea extracts and bioactive theaflavins; plant essential oils and their compounds (+)-α-bisabolol and eugenol; the grape skin compound resveratrol; the kidney bean lectin, marine extracts from algae, seaweeds, and fungi and compounds that are derived from fungi; medicinal extracts and about 30 isolated pure compounds. Also covered are the inactivation of drug-resistant T. vaginalis and T. foetus strains by sensitized light; anti-trichomonad effects in mice and women; beneficial effects of probiotics in women; and mechanisms that govern cell death. The summarized findings will hopefully stimulate additional research, including molecular-mechanism-guided inactivations and human clinical studies, that will help ameliorate adverse effects of pathogenic protozoa.

In the current study the phytochemical profile of 70% ethanol extract of Ziziphus jujubа (Rhamnaceae), cultivated in Bulgaria has been investigated. The fruit extract contained numerous phytochemicals, such as triterpenes, phenolic acids and flavonoids. Five triterpenes, 11 phenolic acids and 5 flavonoids have been identified. The fruit extract had a total phenolic content of 21.62 ± 0.0265 mg/g and total flavonoid content 1.34 ± 0.017 mg/g dried extract. Among the triterpenes with the highest concentration was the betulinic acid 20943.17±527.06 µg/g dried extract, rosmarinic acid (1174.26±29.55 µg/g) among the phenolic acids, followed by myricetin (214.61±5.40 µg/g) as a representative of flavonoids and rutin 3 046.89±76.68 among the quercetin glycosides. The inhibitory effect of Z. jujubа fruit extract has been investigated on the key enzymes linked to diabetes – α-glucosidase and α-amylase. In order to evaluate the type of inhibition a Lineweaver-Burk plot was produced. The results obtained from the enzyme kinetic studies exhibited a mixed noncompetitive-uncompetitive type of inhibition on α-glucosidase and mixed competitive-non-competitive type of inhibition on α-amylase. Besides that the obtained results proved high inhibition of α-glucosidase (79.46% at 1.33 mg.ml-1 extract) and moderate inhibition of α-amylase (39.10% at 0.666 mg.ml-1 extract concentration). These results suggest the possible use of fruits of Z. jujubа in the management of diabetes mellitus.
