ABSTRACT

Abstract Herba Cistanche (Cistanche species) in Traditional Chinese Medicine is used for the treatment of several diseases and symptoms, to include pain. The objective of this study was to evaluate the antinociceptive effect of the hydroethanol extract of Cistanche salsa (C.A.Mey.) Beck, Orobanchaceae, stolons in animal models of pain. Chemical composition of Herba Cistanche was analyzed by HPLC-UV. Mice Swiss Webster (25-30 g, n = 6) were orally pre-treated with Herba Cistanche (10, 30 or 100 mg/kg) and evaluated in the formalin test and in the capsaicin- or glutamate-induced licking response. Kazakh Herba Cistanche is composed mainly by phenylpropanoid glycosides, from which echinacoside, acteoside and tubuloside B are the main constituents. When Herba Cistanche was administered to mice it had an effect in both phases of the formalin test (77% activity at 30 mg/kg for phase 1 and 62% activity at 100 mg/kg for phase 2) suggesting analgesic and anti-inflammatory properties. Kazakh Herba Cistanche was able to reduce the animals licking time after injection of glutamate (81% reduction at 30 mg/kg) and capsaicin (81% reduction at 100 mg/kg). We conclude that phenolics present in the hydroethanol extract of C. salsa could be responsible for its pharmacological profile. In order to source a good quality raw material for Traditional Chinese Medicine we recommended this Kazakh species to be standardized using echinacoside and acteoside as markers.

ABSTRACT

Abstract Choisya ternata Kunth, C. ternata var. sundance Kunth and the hybrid Choisya 'Aztec-Pearl' are three related species belonging to the Rutaceae family. Ethanol extracts were prepared from the leaves of these three species and evaluated in relation to their antioxidant activity using in vitro and ex vivo models. The ethanol extracts belonging to the three species produced a very high antioxidant profile as evidenced by the DPPH radical scavenging activity, the determination of total phenolics and flavonoid equivalent. The generation of reactive species of oxygen in leukocytes stimulated with LPS was dramatically reduced when the three ethanol extracts were used. The alkaloids anhydroevoxine and choisyine were isolated from the ethanol extract of C. ternata using HEMWat (4:6:5:5) as the solvent system by means of high-speed countercurrent chromatography. This was the first time quinoline alkaloids were isolated from this species using HSCCC. These compounds were also assayed for their capacity to inhibit the generation of ROS in leukocytes stimulated by LPS and the results also suggested that they are reactive oxygenase inhibitors.

ABSTRACT

The aim of this review was to extract information of the book Medicinal Plants in Folk Tradition: An Ethnobotany of Britain & Ireland published in 2004 by Allen and Hatfield, to give an overview of plants with medicinal potential and their applications. This study attempts to attest, observe and comment on the diversity of plants, as well as the accompanying information which inevitably is vital for the future development of herbal medicines for human therapy. Initially, the information in relation to medicinal plants in Ireland only was extracted from the above-mentioned book and organised in tables. Afterwards, it was analysed through the construction of maps and the positioning of each piece of information in specific geographical regions of the country. Its division into provinces was taken into consideration as well as into counties within the provinces. These maps and graphs illustrate the most predominantly reported botanical families identified and utilised (Asteraceae, Scrophulariaceae and Lamiaceae), and to the most frequently cited medicinal uses were attributed to topical applications. As a result we can see that the uses of traditional medicines vary among these different geographical areas of the country. Not only different uses were reported but also different plants used to treat the same condition, or different conditions treated with the same plant depending on the county. Various phytopharmaceuticals date back several decades and despite the existing evolving technology, without a doubt herbal medicines can and still do provide exceptional and efficacious outcomes like many of the conventional remedies available today.
