The present study was investigated to establish the diuretic and antiurolithiatic activities of chloroform and ethanolic leaf extract of Melochia corchorifolia. The chloroform and ethanolic leaf extract were administered to experimental rats orally at a dose of 200 mg/ kg and 400 mg/kg. Furosemide (5 mg/kg) was used as reference standard for diuretic activity. The parameters measured for diuretic activity was total urine volume; urine electrolyte concentrations such as sodium, potassium, chloride, and bicarbonates. In the in-vitro antiurolithiatic activity, Calcium oxalate crystallization was induced by the addition of 0.01M sodium oxalate solutions in synthetic urine. The effect of chloroform and ethanolic leaf extract of Melochia corchorifolia (100, 200 and 500 μg/ml) was studied by time course measurement of absorbance at 620 nm for ten minutes using a spectrophotometer. Both the extracts show good in-vitro antiurolithiatic activity. In the in-vivo antiurolithiatic activity, urolithiasis was induced in male rats by administering ethylene glycol (0.75% v/v) in drinking water for 28 days, and the parameters such as oxalate, calcium, and phosphate were...

Cadmium is a known nephrotoxic metal with other toxicities including pancytopenia. Telfairia occidentalis is a medicinal plant with antioxidant and chemoprotective properties. This study was carried out to investigate the ameliorating effects of aqueous extract of Telfairia occidentalison cadmium chloride-induced oxidative stress, renal damage and hematological alterations in rats. Twenty four (24) adult male rats were divided into 4 groups of 6 rats each. Group I received distilled water, group II, III, and IV were administered 5 mg/kg body weight CdCl2, group III; IV was treated with 200 and 400 mg/kg bw respectively of aqueous extract of Telfairia occidentalisfor 14 days while rats in group II were left untreated. Results obtained showed that administration of cadmium caused significant reduction in all the hematological parameters, reduced GSH, ascorbic acid, Superoxide dismutase (SOD), glutathione S-transferase (GST), Catalase (CAT), serum Sodium ion and bicarbonate ions as well as increase in MDA (malondialdehyde) level and serum level of potassium ion, serum urea, and creatinine. However, treatment with various doses of aqueous extract of...

Curcuma is an important genus used in Traditional Medicine in the world. Due to similar morphological characters and same Sinhalese vernacular names of Curcuma species, adulteration or substitution takes place. The current study was conducted to understand the similarities in morphological and microscopic characters by analyzing data using multivariate test on five species available in Sri Lanka; C. albiflora, C. aromatic, C. longa, C. oligantha, and C. zedoaria. Whole plants of Curcuma species were collected in 2016, from wet and dry zones of Sri Lanka. Voucher specimens of the plants were authenticated from National Herbarium, Peradeniya, Sri Lanka. Morphological characters of five Curcuma species and microscopic characters of five Curcuma species using 5 observations of each plant were analyzed. An experiment was conducted as per WHO guidelines and other published data. Statistical tests were performed using Minitab 17. Multivariate test was used to determine the complex relationship among variables by simple correspondence analysis. Analyses examined the relationships between the 25 observations and the associations between variables in two dimensions...

Nature has been a source of medicinal agents since times immemorial. The importance of herbs in the management of human ailments cannot be overemphasized. Different extracts from traditional medicinal plants have been tested to identify the source of the therapeutic effects. As a result, some natural products have been approved as new antibacterial drugs. The objective of this research is to find out the potent antibacterial agents from the selected medicinal plants: Mangifera indica and Osyris lanceolata of Rupandehi, and Palpa districts of Nepal. The Bark and Leaves of the plants Mangifera indica and Osyris lanceolata respectively were subjected to extraction by maceration process using solvent methanol. Screening of antibacterial activity was done by disc diffusion method against the microorganisms Staphylococcus aureus and Escherichia coli at three different concentrations (1 mg/disc, 2 mg/disc, and 4 mg/disc). Both plants showed potent antibacterial activity. Minimum inhibitory concentration (MIC) assay was determined for the two extracts against these bacterias. The concentration 4 mg/disc of M. indica showed maximum activity against both E....

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 three new chemical constituents characterized n-heneitriacont-4-en-16β, 17β, 18β-triol (n-heneitriacontenol, 3), 6, 4′- dimethoxy- 7, 3′- dihydroxy flavone- 7- O- β-D-glucopyranoside (lantanaflavone 7-O-β-D-glucoside, 6), urs-12-en-3β-ol-28-oic acid 3β-D-glucopyranosyl-6´-octadecanoate (ursolic acid 3-O-β-D-glucosyl-6′-oleate, 8) along with five known compounds characterized as n- hexadecanyl oleate (1), n-octadecanyl oleate (2), oleanolic acid (4), ursolic acid (5) and oleanolic acid 3-O-β-D-glucopyranoside (7). The structures of all the isolated phytoconstituents have been established on the basis of spectral data analysis and chemical...
