Inhibition of Ascitic Ehrlich Tumor Cell Growth by Intraperitoneal Injection of Pfaffia paniculata (Brazilian ginseng) Butanolic Residue
This study aimed to investigate the effects of the administration of butanolic residue (BR) of Pfaffia paniculata by intraperitoneal route to Ehrlich ascitis tumor bearing mice. Initially, a toxicity study of P. paniculata BR was performed in which doses of 12.5; 25 and 50mg/Kg were administered by intraperitoneal injection for seven days to Swiss mice. The treatment did not show toxicity. Then...
متن کاملBiodegradable Bags for the Production of Plant Seedlings
The production of plant seedlings has traditionally used polyethylene bags, which are thrown out in the soil or burned after transplant because the large amount of organic material attached to the bags makes recycling difficult. Additionally, when a seedling is taken from the bag for transplant, there is the risk of root damage, which compromises the plant’s development. In this study, we devel...
متن کاملPhytochemical analysis of Pfaffia glomerata inflorescences by LC-ESI-MS/MS.
Pfaffia glomerata contains high levels of β-ecdysone, which has shown a range of beneficial pharmacological effects. The present study demonstrated that inflorescences of P. glomerata contain other important bioactive compounds in addition to β-ecdysone. The identification of compounds from inflorescences using liquid chromatography coupled with electrospray ionization tandem mass spectrometry ...
متن کاملExtraction and Quantitative HPLC Analysis of Coumarin in Hydroalcoholic Extracts of Mikania glomerata Spreng. (“guaco”) Leaves
Foram avaliados vários métodos de extração para os extratos hidroalcoólicos das folhas de “guaco” (Mikania glomerata Spreng.): maceração, maceração com ultra-som, infusão e extração por fluido supercrítico. Dentre os métodos estudados, a maceração com ultra-som proporcionou os melhores resultados, especialmente considerando-se a relação rendimento da extração/ tempo de extração. A cromatografia...
متن کاملEffect of cadmium on growth, micronutrient concentration, and δ-aminolevulinic acid dehydratase and acid phosphatase activities in plants of Pfaffia glomerata
Pfaffia glomerata (Spreng.) Pedersen plantlets were grown under different cadmium (Cd) concentrations (0, 20, 40, 60 and 80 μM) in a hydroponic system during 7 d. Plant growth, micronutrient, chlorophyll and carotenoid concentrations, as well as δ-aminolevulinic acid dehydratase (ALA-D; E.C.4.2.1.24) and acid phosphatase (AP; E.C.3.1.3.2) activities were analysed. Cadmium concentration in both ...
