PHYTOCHEMICAL SCREENING ASSESSMENT, ANTIOXIDANT CAPACITY AND ANTIMICROBIAL SUSCEPTIBILITY OF EXTRACTS FROM CECROPIA PACHYSTACHYA TRÉCUL. CECROPIACEAE (URTICACEAE) AS SOURCE FOR HERBAL MEDICINES DEVELOPMENT
Several plants used for medicinal purposes can be found in the Brazilian Cerrado, among which highlights the genus Cecropia used as a bronchodilator, antitussive, anti-diabetic, anti-diarrheal, anti-hypertensive, anti-inflammatory and vasorelaxant. Between species, there is Cecropia pachystachya belongs to the Urticaceae family. This study aims to evaluate the phytochemical screening, antioxidant ...
Polygonum flaccidum (Polygonaceae) is an annual herb widely distributed in Bangladesh, India, Bhutan, Sri Lanka, and Afghanistan. Objectives of the present study were to determine antioxidant, anthelmintic, cytotoxic, insecticidal and antibacterial activities of methanol extract of P. flaccidum. Antioxidant activity in terms of free radical scavenging ability was determined by DPPH free radical sc...
BIOLOGICAL ACTIVITIES OF EXTRACTS AND SEASONAL VARIATION IN ESSENTIAL OIL COMPOSITION FROM MYRCIARIA GLAZIOVIANA (MYRTACEAE)
Extracts from leaves, stems and flower buds of Myrciaria glazioviana were analyzed for their antioxidant and anticholinesterase activity. The methanolic extracts showed the best results in reducing power (623.52 - 806.15 mg AA/g of extract), DPPH radical scavenging (IC50 = 9.77 - 14.06µg/mL) and lipid peroxidation inhibition activity (21.30 - 66.80 %). These data were correlated to the total phen...
Lantana indica Roxb. (Verbenaceae) is grown as an ornamental plant in tropical and subtropical regions of the world. The plant is used to treat asthma, abdominal disorders, bilious fever, cancer, catarrhal infections, chicken pox, eczema, hypertension, malaria, measles, swelling, rheumatism, tetanus, and ulcers. Phytochemical investigation of a methanolic extract of the leaves led to isolating thr...
EVALAUTION OF ANTHELMINTIC ACTIVITY OF RICINUS COMMUNIS LINN. LEAVES BY USING DIFFERENT TYPES OF SOLVENT
Aqueous and ethanol ethyl acetate chloroform-methanol extracts from the leaves of Ricinus communis were investigated for their anthelmintic activity against Pheretima posthuma and three concentrations (50, 75 and 100 mg/ml) of each extract were studied for activity, in which paralysis and death time of the worm. Both the extract exhibited remarkable anthelminthic activity at all three concentratio...
IDENTIFICATION OF ENDEMIC CURCUMA ALBIFLORA THW. FROM CURCUMA SPECIES GROWN IN SRI LANKA BY DNA BARCODING METHOD
Curcuma is an important genus in traditional medicine. Five plants are reported in Sri Lanka; C. albiflora, C. aromatica, C. longa, C. zedoaria, and C. oligantha. Since the phylogenetic analysis of gene sequences and combining with complete genomic sequences helps to identify the genetic basis of plants, the current study was conducted. Standard CTAB method with little modifications was used for t...
Portulaca quadrifida Linn. (Portulacaceae) is commonly known as a chicken weed in English. In the traditional system, it is used to treat rheumatism and gynecological diseases, urinary tract infections, worm diseases, dysentery and dermatitis. To assess the cytotoxic potential of hydroalcoholic extract of P. quadrifida leaves using brine shrimp assay. Potassium dichromate was considered a standard...
Background: Sickle cell anemia continues to be prevalent in the African population of which Nigeria alone has epidemiology of 25%, and only a few official medications are available, necessitating this current study. Methods: Cnestis ferruginea Vahl ex DC., Connaraceae, Alcornea laxiflora (Benth.) Pax & K. Hoffman Euphorbiaceae, and Spathodea campanulata Beauv., Bignoniaceae, which have various...
Plants are a great source of medicines, which are useful in the treatment of various diseases. Today sophisticated modern research tools for evaluation of the plant drugs are available, but the microscopical evaluation method is one of the simplest and cheapest methods to start with for establishing the correct identity of the source materials. Ximenia americana of family Oleaceae have great medic...
Spirulina platensis is a blue-green alga that widely used as a food supplement over worldwide. Two models were used to study the effects of Spirulina platensis on nociception which was induced by acetic acid (Writhing test), formalin (Paw licking test). Spirulina platensis was administered in the dose range of 200 and 400 mg/kg orally 1 h before pain induction. Spirulina platensis contains β-caro...
