Abstract: The effect of aqueous extract of Cecropia glazioui Snethlage (Embauba) in the rat fetal development. This study was to complement previous assays on the physical and neurobehavioral development of rats resulted from oral administration of 1 g/kg/day Cecropia glazioui Snethlage (C. glazioui) aqueous extract (LD50 > 5 g·kg-1in pregnant rats (peri- and post-natal studies). In the present study, the effect of 2.5 g/kg/week C. glazioui aqueous extract, administered to pregnant rats during 15 days, was verified in the rat offspring development. No acute or chronic toxicity (no effects on mortality or weight average daily gain) were observed. In addition, no effects on reproductive parameters (offspring vitality, placenta and fetus weight, number of corpora lutea on each ovary, pre- and post-implantation loss) and on offspring external morphology were found. We concluded that C. glazioui aqueous extract administered during pregnancy did not cause abnormalities in rat offspring.

Abstract: There is a wide diversity of plants and seasonal crops in Peru, due to the presence of many climatic zones. Numerous plants are used to cure or prevent diseases. These plants are promising candidates for functional foods products. The most frequent form in which they are used is an aqueous infusion or decoction. In this study, we compared the antioxidant properties of ten Peruvian plants infusions and investigated their relation to the phenolic content. The studied plants were: Uncaria tomentosa (cat’s claw), Lepidium meyenii (maca), Berberis vulgaris L. (barberry, agracejo), Phyllantus niruri (chanca piedra), Annona muricata L. (graviola, soursop), Gentianella alborosea (hercampure), Geranium dielsianum (pasuchaca), Tabebuia ochracea (tahuari), Notholaena nivea (“cuti cuti”) and Tiquilia paronychioides (“flor de arena”). Infusions of all studied plants have shown antioxidant activity, though there was a large diversity between the results. The antioxidant properties, determined with DPPH and ABTS scavenging assays as well as FRAP test, were strongly correlated with total phenolic content, while there was no correlation with the carotenoid content.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.516266

The objective of this study was to evaluate the use of biofertilizers and saline waters on gas exchange and growth of medicinal plant Plectrantus amboinicus. The experiment was conducted in the period February to May 2013 in a greenhouse. The experimental design was completely randomized in a 2 × 4 factorial arrangement, with two levels of salinity of irrigation water (ECw: 0.7 and 3.1 dS m-1) and four levels of bovine liquid biofertilizer applied to the soil, corresponding to 0%, 10%, 20% and 30% of the soil volume, with five replications. The experiment lasted 60 days, counted from the beginning of the treatments. The stomatal conductance (gs), photosynthesis (A), transpiration (E), intrinsic water use efficiency (WUEi) were performed at the end of the experiment, and the height, number of leaves and stem diameter at the beginning and at the end. Generally plants subjected to salinity of irrigation water of 3.1 dS m-1 had the lowest values of gas exchange. Moreover, the application of biofertilizers and the interaction between this and salinity did not affect any growth variable studied except the stem length in the final phase which was influenced by salinity at 5% probability by F test. The average values of this variable were 57.22 cm and 69.65 cm when applied water ECw: 0.7 to 3.1 dS m

Abstract: The floristic diversity of plants and their abundance were analyzed in 2.5 km campus to explore their medical importance by random sampling. The results for plant diversity in IIT-M campus showed nearly 100 species of flowering plants, with genera belonging to nearly 40 families. The most dominant family in the present study is Fabaceae with 15 species (25%) of the medicinal trees. In addition, the dominant medicinal herbs belong to the families of Acanthaceae, Apocynaceae, Fabaceae and Rubiaceae containing 4 species (12%) each. The identified medicinal tree and herb are verified with Red data book to explore their conservation status of every identified medicinal trees and herbs. On comparison with the existing IUCN red data list, the conservation status of 73% of trees and herbs identified in the present study were not assessed. Also, the biodiversity of plants focused on ethano-botanical aspects to reveal their medicinal uses.

Health (Health) , 2011, DOI: 10.4236/health.2011.39091
Abstract: Instrumental Neutron Activation Analysis has been used to make a multi-elemental determi-nation in the Zingiber officinalis and Salvia offi-cinalis, plants used in traditional medicine therapy in Algeria and in most countries. The concentrations of five elements Co, Cr, Sc, Sb and Rb have been determined by long irradiation time with 2.7E13 n?cm–2?s–1 thermal flux using a NUR Algerian Reactor. All these elements are present at trace levels. Their implications in Human health are herein discussed. The quality control of the measurements have been evaluated by analysing a HAY (V-10) IAEA-Standard reference material.

Health (Health) , 2013, DOI: 10.4236/health.2013.57149

The study aims to know the medicinal plants used by farming families of communities in four municipalities of the south region of RS for the relief of menstrual cramps. It is a descriptive study that analyzed qualitative data. The subjects were 19 farmers from Cangu?u, Arroio do Padre, Morro Redondo and Pelotas. Data were collected from January and May the 2009, through semistructured interviews. Eight plants used for relieve menstrual cramps were cited. This research showed that the popular knowledge of farmers is consistent, in 100%, with the search made in the scientific literature. It is evident that the plants Apium sp., Plectranhus sp., Cinnamomum sp., Chenopodium ambrostoides, Origamun sp., Petroselimum crispum have evidence in the scientific literature, showing that the individuals in this study use the medicinal plants suitable for their purpose.

Psidium guajava L. has extensive use in folk medicine. The aim of this study was to quantify the levels of phenolic, flavonoids, antioxidant activity, leathality assay and antibacterial and antitumoral activities of the extract of P. guajava. In the dry guava extract there were high levels of phenolics (766.08 ± 14.52 mg/g), flavonoids (118.90 ± 5.47 mg/g) and antioxidant activity (87.65%). The LD50 was 185.15 μg/ml. The MIC value was 250 μg/ml for Streptococcus mutans, Streptococcus mitis and Streptococcus oralis. IC50 of the extract tested in the HeLa, RKO and Wi cell lines was 15.6 ± 0.8 μg/ml, 21.2 ± 1.1 μg/ml and 68.9 ± 1.5 μg/ml, respectively. The results of all analyses allow us to conclude that the dry extract of guava leaves has promising activity to be applied topically in the oral cavity or in the development of antitumor formulation or even be used as a functional food.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.523364
Dactylorhiza hatagirea (D. Don) Soo, commonly known as “Panchaunle”, is an important medicinal plant species distributed throughout the Himalaya region. The present work was conducted in order to assess its availability in natural habitats because of its medicinal properties, cultural significance and declining population density. The work focused primarily on its ecological features and conservation status. The density of D. hatagirea was found to be 2.18 individuals·m-2 with frequency and abundance being 81.81% and 2.67 individuals·m-2, respectively. We considered grazing, trampling, number of cattle and distance to settlement as anthropogenic factors. While grazing and trampling were shown to have a significant, negative impact on population density, we observed no significant change in the number of the species with respect to number of cattle and distance to settlement. We conclude that the species is threatened and that anthropogenic factors have a significant effect on its habitation in the study area.
